This paper is another contribution to knowledge of the caddisfly fauna of India. We redescribe and illustrate Diplectrona marginata Betten 1909 based on previously collected material as well as from fresh collections. The status of D. marginata is validated after Betten (1909) and Martynov (1935) and a neotype is designated for D. marginata because the remaining syntype has been damaged and is not identifiable. Furthermore, D. kinulta Oláh et al. 2020 is considered a synonym of D. marginata based on the similarity of male genitalia. Diplectrona aurovittata (Ulmer 1906) is reported for the first time from India, bringing the number of Indian species of Diplectrona to 10.

Marilia ceylanica Martynov 1936, NEW RECORD FOR INDIA (Figs 6–11) Marilia ceylanica Martynov 1936, 248, textfigs 10, 11, “ Ceylan ” [Sri Lanka]. Material examined. Andaman and Nicobar Islands Union Territory of India: Great Nicobar Island, Gandhinagar, 6º59’6.54”N, 93º50’46.32”E, 18.xi.2018, Gopi & party (NZC), 2 males and 1 female. Diagnosis. Schmid (1958) considered M. ceylanica to be a synonym of M. mixta (Hagen 1858), but Malicky (1989) deemed M. ceylanica to be a valid species. The male genitalia of M. ceylanica are similar to those of M. sumatrana Ulmer 1951. However, in M. ceylanica, segment IX is without any angular horizontal plates above the bases of the preanal appendages (Malicky 1989; Martynov 1936); but in M. sumatrana segment IX bears angular horizontal plates in that position (Malicky 1989, 2010). [Ulmer (1951) described and illustrated tergum X of M. sumatrana without any apical notch in dorsal view, but Malicky (1989) considered that supposed difference from M. ceylanica to be an artifact.] Furthermore, Malicky (1989) compared specimens of M. sumatrana (populations from Sumatra and Thailand) with specimens of M. ceylanica and noted that, in addition to the difference in male genitalia, M. ceylanica can be easily distinguished from M. sumatrana on the basis of additional characters: “the great geographical distance between them, the difference in size (M. ceylanica is only half the size), and in the male forewing of the Thai species [M. sumatrana] the veins R4, R5 and M1+2 (sensu Ulmer) arise practically from one point, in M. ceylanica the last two form a fork” [translated from German]. Malicky (2013) more recently expressed his frustration for diagnosis of most species in Marilia as follows: “So we have to realize that our current methods of species identification in the genus Marilia are insufficient and that any attempt at identification is a pure game of chance” [translated from German]. Future revisionary work combining morphological and molecular studies could provide better insight to the species of this genus. Distribution.

Andaman and Nicobar Islands Union Territory of India: Great Nicobar Island, 10 km. EW road, 12.xi.2018, Gopi & party (NZC), 1 male. Diagnosis. The male genitalia of H. saranganica are similar to those of H. dido Malicky & Chantaramongkol 2000 (Philippines) and H. bonadea Malicky & Chantaramongkol 2000 (Sumatra) in the appearance of the long median keel of segment IX and the apicoventral setose lobe of segment X. However, it differs in having the median keel of segment IX directed posterad in lateral view; the dorsal interlobular gap is U-shaped in dorsal view; and the apical segment of each inferior appendage is slender and long. On the other hand, in H. dido, the median keel of IX is directed more nearly dorsad (posterodorsad) in lateral view; the dorsal interlobular gap is V-shaped in dorsal view; and the apical segment of each inferior appendage is thicker and shorter than in H. saranganica.

Oecetis jacobsoni Ulmer 1930, NEW RECORD FOR INDIA (Figs 1–5) Oecetis jacobsoni Ulmer 1930, 465–466, 492, 498, figs 132–134. Material examined. India: Andaman and Nicobar Islands Union Territory of India: North Andaman Island, Diglipur, 13º15’54.72”N, 92º58’5.00”E, 19.i.2019, Dubey (NZC), 1 male and 4 females. Diagnosis. The male genitalia of Oecetis jacobsoni are similar to those of O. meghadouta Schmid 1958, O. ixion Malicky 2005, and O. kodros Malicky 2005. In all these species, each side of segment IX of the male genitalia (in lateral view) has a concave subdorsal excision anteriorly; the posterior subdorsal edge has a slight excision ending in a blunt projection at mid-height (in lateral view). Among these species, O. jacobsoni is more similar to O. meghadouta which is also a widespread species in the Oriental Region. However, in O. jacobsoni, the subdorsal excision on each side of the anterior edge never reaches to the dorsal meson of segment IX, the projection on each posterolateral edge of segment IX is broad and acute (but not toothed), whereas on each side of segment IX of O. meghadouta in lateral view the subdorsal excision on the anterior edge extends to the dorsal meson of segment IX and the posterolateral edge of segment IX has a toothed projection. Also, as observed by Malicky (2005), there are visible differences in the spots on the wings that are more nearly uniform, not surrounded by bright hyaline regions and less conspicuous than those of O. meghadouta in which each spot appears as a flower with round petals surrounded by a bright circle.

Dipseudopsis robustior andamanensis Weaver & Malicky 1994 Dipseudopsis robustior andamanensis Weaver & Malicky 1994, 134, fig. 47. While identifying species of the genus Dipseudopsis, the precise orientation of the modified hind tibial spur is crucial because slight rotations of a tibia produce different perspectives of the spur (Weaver & Malicky 1994; Oláh & Johanson 2010c). Furthermore, the male genitalia are rather simple, often lacking conspicuous characters (Oláh & Johanson 2010c). According to Weaver and Malicky (1994), “ D. robustior robustior Ulmer 1929 is the most common species of genus Dipseudopsis in Thailand and is somewhat difficult to distinguish from D. collaris and D. infuscata. Possibly these species are merely variants of a widely distributed species.” All three of these species are widespread in Southeast Asia: D. r. robustior has been reported from Cambodia, Indonesia (Sumatra), Peninsular Malaysia, Myanmar, Thailand, and Vietnam; D. collaris from China (Hong Kong, Guangdong, Jiangsu, Jiangxi, Zhejiang), Japan (Hongshu, Kyushu), and the Philippines; and D. infuscata from China (Yunnan) and Indonesia (Java, Kalimantan, Sulawesi, and Sumatra). On each hind tibia of D. robustior robustior the apical points of the modified spur are unequal: one has a long slender curved point and the other has a short broad point. In D. collaris the points are shorter and subequal, only 1/3 as long as the base. In D. infuscata, “the two apical points of the modified spur [have] the longer point straight and slightly shorter than the unmodified base of the spur, and the shorter point curved with its apex directed mesad” (Weaver & Malicky 1994). Dipseudopsis robustior andamanensis Weaver & Malicky 1994 differs from D. r. robustior in that each hind tibia has a pincer-like modified hind tibial spur with two subequal points. The more recently described species Dipseudopsis cocon Oláh & Johanson 2010c (from Vietnam) is very similar to D. robustior andamensis, as both of these species have subequal crescent-shaped, pincer-like points of the modified hind tibial spurs. In their diagnosis for D. cocon, Oláh and Johanson (2010c) did not mention D. robustior andamanensis. Malicky (2013) suggested that D. cocon may be a synonym of D. robustior andamanensis. The only difference appears in the ratio of the length of the undivided base of a modified hind tibial spur to that of its two apical branches: The ratio is 0.5 for D. cocon and 1.6 for D. robustior andamanensis. This difference may or may not be diagnostic for these two species-group taxa and D. robustior andamanensis may or may not be a distinct species rather than a subspecies of D. robustior. Resolution of these questions and questions about the status of D. collaris and D. infuscata will depend on morphological and molecular comparisons of multiple specimens of each of these purported taxa from Southeast Asia. For now, the conservative choice is to maintain the current situation, listing D. robustior andamanensis as an endemic subspecies on South Andaman Island.

The male genitalia of this species are similar to those of P. jotham Malicky 1993 (also reported from Nepal). However, in P. amphion, the preanal appendages are very broad, leaf-like in lateral view; the spiniform processes of the preanal appendages are strongly directed dorsad in lateral view; and the inferior appendages are broad basally, each with a spine-like, arched process at mid-length on the mesal surface and visible in ventral view. In contrast, in P. jotham, the preanal appendages are not as broad (only finger–like) and narrow in lateral view; the spiniform processes of the preanal appendages are not strongly bent; and the inferior appendages are broad but without any spines or arched processes at mid-length on the mesal surface in ventral view.

(2016), reported from China (Guangdong, Guangxi, Sichuan) and Indonesia. Diagnosis. According to Malicky (2013), D. obscura (Ulmer 1930) is a synonym of D. aurovittata. These two species are very similar. No wing patterns are visible (perhaps because our specimens are preserved in alcohol). However, differences exist that distinguish these species (Malicky 2002). Variants for this species also exist (Malicky 2002), but we infer that illustrated variations depend on the orientation of a specimen as drawings or photographs are prepared. For example, in dorsal view (Fig. 22), the left lateral lobe of tergum X is very similar to that of the type of D. aurovittata, but the right lateral lobe appears smaller because it was drawn by rolling the genitalia slightly. Differences are clear and obvious. The differences include the following: In D. aurovittata the mesocaudal lobes of tergum X are directed dorsad in lateral view and the lateral (outer) edges of the lateral lobes of tergum X are pointed in dorsal view; whereas in D. obscura the mesocaudal lobes of tergum X are directed posterad in lateral view, and the lateral (outer) edges of the lateral lobes of tergum X are rounded in dorsal view.

D. kinulta Oláh et al. 2020: 160–161, figs 23–27; holotype male: China, Tibet, Muotuo [county], 80K 1000 m, 24.vii.2012, leg. Li Wen-liahng; deposited in the Entomological Museum of China Agricultural University, Beijing; NEW SYNONYM. Neotype. We designate a neotype for D. marginata (Betten 1909). One of the 2 female syntypes from India [Kurseong, West Bengal, collected by Dr Nelson Annandale, in May 1906] is missing from the NZC and is probably destroyed. The senior author himself examined the remaining one of these syntypes which is in very bad condition without head and with damaged wings, although the abdomen is intact. Another set of specimens from the Indian Himalayas (Martynov 1935: 181) was assigned to D. marginata and a male was described by Martynov (1935). The original description of the species is ambiguous and incomplete, creating confusion and uncertainty about the identity of this species and its distinction from other species (Schmid 1961: 201; Malicky 2002: 1214). Females of this genus are very similar and diagnostic characters for distinguishing them are subtle or unknown (Ito & Nozaki 2018; Mey 1999; Neboiss 2002; Wells & Neboiss 2018). Therefore, although Malicky (2002) recommended that the name Diplectrona marginata should be treated as a nomen dubium, we prefer to select a neotype from among a series of specimens in the Indian Himalayas (Martynov 1935: 181–182) and conforming with the limited details of the original description, thereby “clarifying the taxonomic status” of the species (International Code of Zoological Nomenclature 1999, Article 75.1). The specimen selected here is said by Martynov (1935) to “represent a mountain form of the species.” Material examined: Neotype: Male. India: Collection Label Verbatim: Punjab, Ghuma, Simla Hills, 3760 ft., 6–8-ix-1925, B.

The male genitalia of D. marginata, in the shape of the lateral lobes of tergum X, are similar to D. jacobsoni Malicky and Chantaramongkol 2002 and D. pachalatkoi Malicky 2009. However, the mesocaudal lobes of tergum X are fused half their length, slender basally, broad apically, mesoapically pointed, narrowly separated apically in dorsal view in D. marginata; whereas the mesocaudal lobes of tergum X are broad at their base and separated apically in D. jacobsoni and the mesocaudal lobes of tergum X are fused, broad at their base and rounded apically with a narrow mesal separation in D. pacholatkoi. Furthermore, in D. marginata, the lateral lobes of tergum X are more divergent than in those species and a small inner lobe-like structure (or fold) is visible on the mesal margins of the lateral lobes of tergum X in dorsal and lateral views in D. marginata, a unique characteristic for this species. Drawings of genitalia of three other specimens are provided to show variation. These were redrawn to show the variation in the lateral lobes of tergum X which might be seen on opposing lateral lobes even in genitalia of the same specimen. For example, Fig. 19 generally agrees with fig. 24 of Oláh et al. (2020) in dorsal view. These are shown to justify our conclusion that this species is widely distributed with local variation and complexity or adaptive traits based on morphology. Redescription of adult male. Color in alcohol light brown, maxillary palp infuscate, legs and antennae pale yellow, dorsum of head dark brown, no setae or hairs visible on eyes. Length from tip of head to apices of folded forewings about 7.25 mm; maxillary palps each about 1.75 mm long, segment V longest; labial palps small, each 0.50 mm long. Length of each forewing about 6 mm; venation typical for genus; discoidal cell small; forks II and III petiolate, Cu 2 and A curved. Hind wings each 5.25 mm long, broad; Sc very thick; R1 fine and sinuate, fork I present. Gland on V sternum visible, filament directed posterad, length of filament more than 1.5x but less than 2x sternite length. Male genitalia (Figs 6–20). Abdominal segment IX annular; anterolateral margins convex, angled at anterior ends of pair of internal longitudinal carinae above middle; posterior margins irregular, produced slightly over bases of inferior appendages. Tergum X divided into pairs of mesocaudal lobes and lateral lobes; mesocaudal lobes fused, apically separated for short distance, blunt apicomesally, longer than lateral lobes; lateral lobes covered basally by broad and setose preanal appendages, broad basally and divergent with distal margins curved laterad, pointed, each with small sclertotized fold on mesal surface. Preanal appendages paired, broad, with prominent large setae visible both in lateral and dorsal views. Inferior appendages each 2-segmented; basal segment long, extending beyond mesocaudal lobes of tergum X, broad basally and apically in lateral view, slightly constricted and with slight bend dorsad near base, in ventral view abruptly curved mesad preapically; apical segment broad at base, 1/3 as long as basal segment in lateral view, curved mesad in ventral view and sharp apically. Phallus, tubular, slightly angled ventrad near base, with one pair of elongate spines and ventral scoop-like structure apically; phallicata complex and with pair of long, semicircular sclerotized ventral lobes in ventral view. Recently, Oláh et al. 2020 described D. kinulta from Tibet, mentioning in the diagnosis that this species is similar to D. burha because both of these species have subquadrangular, plate-like paraprocts (lateral lobes of tergum X) with variously divergent apical patterns. They did not mention D. marginata but observed that the male of D. kinulta differs from that of D. burha by the character combination of small seta-less eyes, a pair of large internal sacs in segment VIII, long posteroventral filaments on sternite V (2.24 times as long as the sternite), fork I on the hind wings, elongate lobes of segment X; and a deltoid head of the phallic organ. In contrast, the male of D. burha is characterized by lateral filaments of segment V that are 1–2 times as long as the segment, small internal glands of segment V, absence of internal glands of segment VIII, and a different shape of the genitalia (Malicky 2002; Ito & Nozaki 2018: 547, figs 2A, 2B). The male genitalia of D. burha are distinguished from those of other congeneric species (including D. marginata) mainly by large preanal appendages (p.a.) and segment X having each subquadrate lateral lobe often with a depression in the apical margin in dorsal aspect and its well-developed mesocaudal lobes (m.c.l.) are separated by a narrow mesal slit in dorsal aspect (Malicky 2002: pl. 14; Ito & Nozaki 2018: 547, fig. 2C). According to Oláh et al. (2017, 2020), the paraprocts are an extremely stable and invariant organ in a species but differing among species, including those in Diplectrona. Paraprocts act as titillating or stimulating organs of the genitalia, typically formed by an adaptive mechanism, and are a stable genetic component compared to the variable neutral organs under the influence of stochastic events. They (2020) conclude that Diplectrona is very diverse in southern Asia, with several species complexes currently identified as a single species, complexes they purport to be best analyzed with “fine phenomics.” The remaining questions and the validity of their research program, of course, can be addressed in future research based on population samples, molecular studies, and more care with a research focus on adaptive speciation traits. In the meantime, based on the observed morphological similarity, we consider D. kinulta a synonym of D. marginata. Distribution.

Diplectrona indica (Mosely 1931) (Figs 1–5) Diagnosis. This species is similar to Diplectrona jacobsoni Ulmer 1909, D. ismene Malicky 2002, D. hermione Malicky & Chantaramongkol 2002, and D. eurykleia Malicky 2002 as the dorsal views of the male genitalia are very similar in all these species, especially similar to D. ismene. However, the lateral lobes of tergum X are twisted outwards in D. indica at 2/3rd of their length in dorsal view and are longer than the mesocaudal lobes; whereas the lateral lobes, though twisted, are almost equal to the mesocaudal lobes in length in dorsal view in D. ismene. Description. Adult male color in alcohol dark brown, wings light brown, antennae and maxillary palps infuscate, dorsum of head and thorax black. Length from tip of head to apex of folded forewings about 7.25 mm; maxillary palps each 2.25 mm long, segment II longer than III, V as long as I–IV combined; labial palps each 0.75 mm long. Length of each forewing about 6 mm, venation typical for genus; Sc and R1 running independently to wing apex; each hind wing about 5 mm long, Sc thickened, R1 bowed subapically, fork I present. Male genitalia (Figs 1–5). Abdominal segment IX annular, anterolateral margins slightly convex; posterior margin nearly straight, produced ventrolaterally over bases of inferior appendages. Tergum X divided into paired mesocaudal and lateral lobes; mesocaudal lobes each apically rounded and slightly convergent in dorsal view, apicomesally separated to mid-length; enclosed by projecting lateral lobes. Lateral lobes each broad basally in lateral and dorsal views, distally narrow, angulate, slightly constricted, twisted, and divergent preapically. Inferior appendages long, stout, slender; each with basal segment about 3 times as long as apical one; apical segment small, curved mesad sub-basally and pointed apically. Phallus tubular, elongate, slightly angled near base, with 2 pairs of elongate dorsolateral spines and ventral scoop-like structure possibly representing phallicata. Material examined.

Potamyia phaidra Malicky & Chantaramongkol 1997, NEW RECORD for India (Figs 13–20) Potamyia phaidra Malicky & Chantaramongkol 1997 (in Malicky 1997: 1037, plate 7) Potamyia trenhona Oláh & Barnard (in Oláh et al. 2006: 753, fig. 36), NEW SYNONYM Diagnosis. Potamyia aureipennis (Ulmer 1930) is similar to P. yunnanica (Schmid 1959). Segment IX is longitudinally short dorsally in lateral view, tergum X in lateral view has its apex much curved dorsad, the apical hook reaching to the height of the setose area (superior or preanal appendages) in P. yunnanica. Whereas, in P. aureipennis segment IX is well developed dorsally in lateral view, tergum X has its apex curved but is broad and not reaching above half the height of the setose area (superior or preanal appendages) in lateral view. Further, variations are already reported in genera of Hydropsychinae for many species from this region. Similarly, P. trenhona Oláh & Barnard 2006 from Vietnam, P. phaidra Malicky & Chantaramongkol 1997 from Thailand, Vietnam, and Laos, and P. assamana Oláh & Schefter 2008 (in Oláh & Johanson 2008) from India appear to be variants of P. aureipennis. However, P. auripennis and P. phiadra are distinct species (Malicky personal communications). These differences are obvious in the male genitalia of these two species; the differences are small but constant in the shapes of tergum X and in the apical segments of the inferior appendages of these two species. The apex of tergum X varies in the formation of the hook: in P. auripennis the dorsal margin of tergum X appears to be rounded in lateral view, the apex of the hook is not recurved anterodorsad, the distal incision is almost concave in dorsal view; the apical segment of each inferior appendage has its mesal margin slightly bulging before the apex in ventral view. On the other hand, in P. phaidra the dorsal margin of tergum X in lateral view is quadrate, the apex of the hook is recurved more nearly anterodorsad, the distal incision is almost round in dorsal view; the apical segment of each inferior appendage has its mesal margin almost concave. Further, while describing P. trenhona, Oláh & Barnard (2006) wrote that this species is similar to P. phaidra but the spine-like process on the hook is small and caudally situated, its surface is much simpler and the stem of the phallic apparatus is not geniculate in P. phaidra (which is not visible in the illustrations by Oláh et al. 2006, page 770). These variations, apart from the modification caused by variable ecological conditions, are also subject to slight modifications in preparations and drawing techniques and especially in the preparations from the dry specimens (structures shrivel in dry-preserved specimens). So, P. trenhona is considered here a synonym of P. phaidra. Furthermore, P. assamana Oláh & Schefter (2008) from (Kameng, Arunachal Pradesh) may also be simply a variant of P. phaidra because it differs only in the deeper incision of tergum X in dorsal view. If these hypotheses are true, then this species could be widely distributed in the northeastern states of India. Material examined.

Hydromanicus inferior Chantramongkol & Malicky 1995 NEW RECORD for India (Figs 11–12) Hydromanicus inferior Chantaramongkol & Malicky 1995, 105 (5): 93 Diagnosis. The male genitalia of Hydm. inferior Chantaramongkol & Malicky 1995 are similar to those of Hydm. punctosalis Mey 1996 (Thailand, Vietnam) and Hydm. fallax Mey 1996 from Vietnam as well as Hydm. sikkimensis sp. nov. However, the preanal appendages of Hydm. inferior are very characteristic, i.e., very broad to 2/3 length, and apical 1/3 very narrow in both lateral and dorsal views. The apices of the apical setose lobes of tergum X are truncate in dorsal view in the original description and illustrations by Chantaramongkol & Malicky (1995) but are somewhat rounded in our specimens from India. In the other three species, the preanal appendages vary from fingerlike to foliose and slender and the apices of the apical lobes of tergum X are rounded in dorsal view.

Two new species of genus Hydromanicus Brauer 1865 are described and illustrated: Hydromanicus religiosus sp. nov. and Hydromanicus sikkimensis sp. nov. (both from Sikkim). Potamyia phaidra Malicky & Chantaramongkol 1997 (from Meghalaya) and Cheumatopsyche chrysothemis Malicky & Chantaramongkol 1997 and Hydromanicus inferior Chantaramongkol & Malicky 1995 (both from West Bengal) are also reported for the first time from India. Further, the species Potamyia trenhona Oláh & Barnard 2006 (in Oláh et al. 2006) is considered a synonym of P. phaidra based on the similarity in wing venation, male genitalic appendages, and phallic structure.

Hydromanicus religiosus sp. nov. (Figs 1–5) Material examined. Holotype: Male, India: Sikkim; Chungthang, 27°36’14.04’’N, 88°38’47.04’’E, 2200 m, 15.ix.2009, Pandher & Parey, (NPC). Paratypes. 2 females, collection data same as of holotype. Diagnosis. This species is unique in having reduced preanal appendages in its male genitalia. The male genitalia of this species are similar to those of Hydromanicus hermosus Banks 1934 and Hydm. elam Malicky 2009 (both from Borneo) in lateral view. However, in Hydm. religiosus the apicolateral lobes of segment IX are very pointed and produced in lateral view; tergum X is broad in dorsal view; the posterodorsal keel of segment IX is open. In Hydm. hermosus and Hydm. elam the apicolateral lobes of segment IX are not strongly produced and are slightly rounded in lateral view; tergum X is not as broad as in Hydm. religiosus in dorsal view; the posterodorsal keel of segment IX is open in Hydm. elam but closed in Hydm. hermosus in dorsal view. Description, adult male. Color in alcohol brown. Wing membrane light brown. Length from tip of head to apices of folded forewings about 10 mm. Forewings each 8.50 mm long, venation typical for genus; crossveins m-cu and cu separated; Sc and R running independently to wing margin; Cu2 and A separately joining wing margin. Hind wings each about 6.50 mm long; fork I present; median cell closed. Male genitalia (Figs 1–5). Abdominal segment IX long, tall, convex anterolaterally, apicolateral lobe on each posterolateral margin broad and triangularly produced; anterior apodeme dividing segment IX into broad sternum and small dorsal tergum in lateral view; in dorsal view anterior margin concave; posterodorsal keel (MK) broad, triangular, open distally. Preanal appendages (PA) lobe-like, each with narrow base, sparsely setose, not arising on elevated tubercle. Depression between dorsum IX and tergum X slightly demarcated. Tergum X broad, quadrate both in lateral and dorsal views, apically pointed; apical setose lobes (ASLX) seen in profile at apicolateral corners in dorsal view, capitate apically in lateral view; dorsal inter-lobular gap (ILG) small and delimited by apical setose lobes; anterodorsal setose lobes (ADSLX) reduced. Inferior appendages (INF) each two-segmented: basal segment (coxopodite) long, slender, and sinuous in lateral view, curved mesad in ventral view; apical segment (harpago) small, broad basally and slightly narrowing to mesally hooked apex in ventral view. Externally, basal 1/4 of phallic apparatus (phallotheca) directed dorsad then bent caudad; posterior part of phallotheca horizontal, slightly sinuous, ending distally in pair of sclerous endothecal processes, regularly semicircular in dorsal view; pair of small, irregular sclerites (possibly representing vestigial phallicata) located between and beneath sclerous endothecal processes. Internally, ejaculatory duct (not shown) narrow, tubular, entering phallus through anterior phallic foramen and ending at gonopore near base of phallus; larger and retracted and inverted membranous endophallus extending from gonopore posterad to pair of small sclerites. Broad and pointed pair of sclerous endothecal processes (apicoventral keels) dominating apex of phallus in lateral view. Distribution. India: Sikkim. Etymology. This species is named with respect to the religious importance of the type locality. According to the belief of the local people in Chungthang, the First Sikh Guru visited here in 1509 AD. He blessed this place and spread rice grains as there was no food grown locally. This is the only place in North Sikkim where rice cultivation occurs with his blessings., Published as part of Pandher, Manpreet Singh, Kaur, Simarjit & Garima, Deepti, 2021, New species and new records of Hydropsychinae (Insecta: Trichoptera: Hydropsychidae) from India, pp. 364-376 in Zootaxa 4915 (3) on page 366, DOI: 10.11646/zootaxa.4915.3.5, http://zenodo.org/record/4456544, {"references":["Banks, N.

Chimarra gangtokensis sp. nov. (Figs. 1���5) Material examined. Holotype: Male, India: Sikkim; Gangtok, 27 �� 19���49.764��� N, 88 �� 36���48.772��� E, 1800 m, 17.v.2011, Pandher & Parey (NPC). Paratype. 1 male, collection data same as of holotype. Diagnosis. Chimarra gangtokensis sp. nov. is similar to C. talos Malicky 2007, C. nahesson Kimmins 1964, and C. megara Malicky 2007 due to the presence of long, pointed, sclerotized lateral lobes of tergum X in lateral view. Chimarra gangtokensis is most similar to C. megara in the general structure of male genitalia. However, in C. gangtokensis sp. nov. segment IX has its posterolateral margins produced and subtriangular, and the arms of the mesal lobe of tergum X are long and curved dorsad apically, whereas in C. megara segment IX has its posterolateral margins slightly convex and the arms of the mesal lobe of tergum X are directed posterodorsad and are not curved apically. Moreover, there is a distinct difference in the shape and number of endothecal spines. Description. Adult male, color in alcohol black, dorsum of head black, wings fuscous. Body covered with black and scattered pubescence. Length from tip of head to apices of folded forewings about 6.25 mm; antenna each 4.25 mm long; maxillary palps each 1.25 mm long, its segment III slightly longer than II; labial palps each 0.70 mm long. Length of each forewing 5 mm; discoidal cell about 2 times as long as its width. Length of each hind wing 3.75 mm. Male genitalia (Figs. 1���5). Segment IX with tergum very reduced mesally and produced anterad submesally; anterolateral margins concave; anteroventrally much produced; posterolateral margins produced and subtriangular medially; posteroventral process present. Preanal appendages angled obliquely posterodorsad, setose, semicircular in lateral view; globular in dorsal view. Inferior appendages longer than tergum X, almost uniformly wide, each gradually narrowing towards apex, setose in lateral view; in ventral view wide basally, constricted medially on outer edge; mesally with three preapical dents and pointed apically. Tergum X with divergent pair of sclerotized lateral lobes and convergent pair of projecting mesal lobes: each lateral lobe wide basally, down-curved at midlength and slender towards pointed apex, with multiple sensilla in lateral view; in dorsal view wide sub-basally, distal 2/3 gradually tapering with slightly concave outer edge towards pointed apex; mesal lobes directed posterodorsad, narrow at base, wide medially, narrow towards apex, hooked dorsad in lateral view; digitate, smaller than lateral lobes in dorsal view. Phallobase rounded and sclerotized; endotheca tubular, length not discernable, with 2 lateral rows of small comb-like spines and pair of large, long, laterally directed spines visible in ventral view. Distribution. India: Sikkim. Etymology. This species is named after the type locality Gangtok., Published as part of Kaur, Simarjit, Garima, Deepti & Pandher, Manpreet Singh, 2020, New Species and New Records of Caddisflies (Insecta: Trichoptera) from India, pp. 350-360 in Zootaxa 4747 (2) on page 351, DOI: 10.11646/zootaxa.4747.2.7, http://zenodo.org/record/3694852, {"references":["Malicky, H.

Cheumatopsyche chryseis Malicky & Chantaramongkol 1997, NEW RECORD for India (Figs. 10–14) Cheumatopsyche chryseis Malicky & Chantaramongkol 1997 (in Malicky 1997b, 1030) Material examined. India: West Bengal; Suntalikhola Park, 22 ° 31’7.14” N, 88 ° 21’4.32” E, 25–27.ix.2018, Pathania & party (NZC), 6 males. Diagnosis. Cheumatopsyche chryseis is similar to Ch. concava (Ulmer 1930), Ch. chrysothemis Malicky & Chantaramongkol 1997 (in Malicky 1997b), and Ch. copia Malicky & Chantaramongkol 1997 (in Malicky 1997b). However, in Ch. chryseis the apical segment of each inferior appendage is slender and pointed at the apex whereas the apical segment of each inferior appendage is wide in Ch. concava and broad basally in Ch. chrysothemis and Ch. copia. Moreover tergum X is almost dome-shaped at midlength in dorsal view in Ch. chryseis whereas tergum X is almost triangularly produced at midlength in Ch. concava, blunt in Ch. chrysothemis, and with a midlength concavity in Ch. copia. Distribution. Thailand, India.

Chimarra kailishchandrai Malicky 1997a, NEW RECORD for North Andaman Island Chimarra kailishchandrai Malicky 1997a, 220 Material examined.

Chimarra kailishchandrai is similar to Chimarra nepalensis Kimmins 1964 and many other species which have segment IX with anterior and posterior edges almost parallel in lateral view. All of these species have very long and broad inferior appendages, but C. kailischandrai has a very long and distinct shape of the lateral lobes of tergum X (bent S-shaped). Distribution. India (Andaman & Nicobar Islands) Remarks: The spelling of the species epithet is unfortunate. In the original description, Malicky (1997) consistently spelled the epithet as ���kailishchandrai��� and provided the following etymology: ���This beautiful species is dedicated to Dr. Kailish Chandra with compliments.��� Dr. Chandra���s given name is actually spelled Kailash. Because there is no evidence of an inadvertent error in the original publication itself, The International Code of Zoological Nomenclature (International Commission on Zoological Nomenclature 1999, as amended 2020, Article 32) precludes emendation of the original spelling., Published as part of Kaur, Simarjit, Garima, Deepti & Pandher, Manpreet Singh, 2020, New Species and New Records of Caddisflies (Insecta: Trichoptera) from India, pp. 350-360 in Zootaxa 4747 (2) on pages 351-353, DOI: 10.11646/zootaxa.4747.2.7, http://zenodo.org/record/3694852, {"references":["Malicky, H.

Polyplectropus admin Malicky & Chantaramongkol 1993, NEW RECORD for India (Figs. 20���25) Polyplectropus admin Malicky & Chantaramongkol 1993, 452 Material examined. India: Andaman & Nicobar Islands; Diglipur, Lamiya Bay, 13 �� 12���15.9��� N, 93 �� 01���29.0��� E, 9.viii.2019, Dubey (ZSIANRC), 1 male; Kalpong, 13 �� 14���12.7��� N, 92 �� 58���21.4��� E, 8.viii.2019, Dubey (ZSIANRC), 2 males, 1 female. Diagnosis. This species has very peculiar male genitalia. Tergite VIII is very large (produced distally to cover all of the flat IX segment as well as the preanal appendages in both dorsal and lateral views. Sternite IX is flat, somewhat dorsoventrally compressed. In the original description (Malicky & Chantaramongkol 1993) there appears to be one pair of dorsobasal processes of the preanal appendages, but one pair of small membranous process also emerge from the bases of the preanal appendages (which were illustrated by Malicky & Chantaramongkol 1993; Taf. 9). Inferior appendages are also very characteristic, being narrow but with a depression just before the apical end and in ventral view very broad with an inward-directed subdistal tooth. Remarks. The occurrence of this species in India was suspected by Malicky 2010 in ��� Atlas of Southeast Asian Trichoptera��� but without any confirmation. So the collection of this species from Andaman and Nicobar Islands confirms his suspicion and also strengthens the evolutionary theory that these Islands were once part of the mainland (now part of the Sundaland Biodiversity hotspot).

Cheumatopsyche globosa (Ulmer 1910), NEW RECORD for India (Figs. 6���9) Cheumatopsyche globosa (Ulmer 1910, 56) Material examined. India: Arunachal Pradesh; Ramsing, 27 �� 55���40.548��� N, 95 �� 29���21.012��� E, 26.x.2017, Maheshwaran & party (NZC), 1 male. Diagnosis. Cheumatopsyche globosa (Ulmer 1910) is very similar to Ch. truncata Martynov 1935 described from India. Probably, Ch truncata is a synonym of Ch. globosa. Malicky 1997b also suggested this probable synonymy while describing and illustrating the variations of Ch. globosa from Asia. Furthermore, there are considerable similarities in the colour pattern of the forewings (in both of these species it is light brown but some specimens from Thailand have bright spots) and also the wing length is the same (5���7 mm) as mentioned by Malicky 1997b. The only possible difference is in the shape of tergum X in these species. Ch. simayorum Ol��h & Johanson 2008 also seems to be the same species. We refrain from designating these species as synonyms pending further morphological and molecular study.

As pointed out by Malicky (2010), this species is very similar to Oecetis iphitos Malicky 2005 and Oecetis philoktetes Malicky 2005 as all of these species belong to the Oecetis testacea Group and have a very similar color pattern on the forewings. However, Oecetis asmada has the dorsal branch of each inferior appendage very broad in lateral view, whereas in Oecetis iphitos each inferior appendage has the dorsal branch in the form of an equilateral triangle and Oecetis philoktetes has each inferior appendage with three tooth-like structures: one ventral, one dorsal, and one median tooth; from each of these teeth arises a very fine long appendage which is bent dorsad in lateral view.
