Thorax and mtg I+II. Pronotum attenuated anteriorly; anterolateral borders oblique; anterolateral angles triangular, not protruding; collar ill-defined, anterior margin concave; disc laterally with three prominent tubercles on either side. Mesonotum with a pair of large tubercles on either side; meso-, metanotum and mtg I+II fused, with a median longitudinal strongly elevated ridge with a pair of large tubercles on each segment, flanked by deeply punctured sclerites laterally. Abdomen. Fused mtg III to VI forming the tergal plate, anteriorly fused to mtg I+II, median pentagonal elevation highest on mtg IV, then sloping posteriorly flanked by a pair of transverse short ridges on mtg III, lateral apodemal punctures deep; deltg II triangular, reaching to mesonotum anteriorly, anterolaterally delimited by large dorsolaterally produced metathoracic scent gland evaporatoria which are visible from above; mtg VII strongly elevated posteriorly with a transverse ridge; spiracles II absent, III���IV ventral, V���VII sublateral and visible from above, spiracle VIII terminal on paratergites VIII, these short and truncate. Venter. Pro-, meso- and metasternum flattened medially, smooth and glabrous at middle, lateral parts with sparse pilosity; mst VII of male glabrous and smooth medially with a prominent round tubercle at middle. Etymology: The generic name is composed of ���para-��� (Greek) close to and Cremastaptera.

Oblongocoris Bai, Heiss & Cai, gen. nov. Type species. Oblongocoris hainanensis Bai, Heiss & Cai, sp. nov. Diagnosis. Apterous, of medium size (5.4���5.7 mm), body oblong oval; coloration blackish brown; surface rough, rugose and glabrous; lateral margins of body, legs and antennae with setigerous tubercles; thoracic segments fused to mtg I+II, with a median pentagonal ridge along meso- and metanota which is restricted, depressed and carinate along mtg I+II and flanked by a pair of transverse ridges on mtg I; fusion line between metanotum and mtg I+II marked by a suture; mtg III to VI fused into a subquadrangular tergal plate; spiracles II ventral, III���IV sublateral, IV at most faintly visible from above, V���VII lateral and visible from above. Oblongocoris gen. nov. resembles Rotundocoris Bai, Heiss & Cai 2019 from Hainan, China, sharing its basic habitus, but is distinguished from the latter by a set of morphological features: in Oblongocoris gen. nov. the lateral margins of the thoracic segments are incrassate, each showing three parallel layers in lateral view; the median deep furrow on the fused mtg I+II is flanked by a pair of transverse ridges on mtg I; and the pro-, meso- and metasterna are fused medially without a visible fusion suture between each other; whilst in Rotundocoris the lateral margins of thorax are not incrassate, showing two layers laterally; mtg I+II are without a pair of transverse ridges on mtg I; and the pro-, meso- and metasterna are fused medially with distinct fusion sutures between each other. Description. Head longer than width across eyes; genae slender, short; antenniferous tubercles stout, conical, apically pointed; eyes small, semiglobose, with convex face; postocular tubercles small, not protruding; postocular borders converging posteriorly to constricted neck; antennae short and slender, about 1.6 times as long as width of head, first segment longest, third longer than fourth, second shortest, first stout, clavate, second and third cylindrical, fourth fusiform; rostrum arising from a slit-like opening of atrium, not reaching limits of rostral groove. Thorax and mtg I+II. Pronotum strongly attenuated anteriorly, anterolateral angles rounded, granular, not protruding beyond collar, disc with medial groove. Meso- and metanota separated only laterally, with median pentagonal ridge, anterior surface on half length of ridge with a median shallow longitudinal sulcus, posterior surface of ridge smooth; metanotum with deep furrows adjacent to medial ridge, separated from mtg I and II by thin suture; lateral margins of thorax incrassate, showing three parallel layers laterally, with deep cleft between pro-, meso-, and metanota; mtg I+II fused, with a deep median groove with a thin longitudinal carina flanked by a pair of transverse elevated ridges and further laterad with a pair of large subtriangular deeply excavated depressions. Abdomen. Mtg III to VI fused into a subquadrangular tergal plate, anterior margin straightly elevated on median line with usual pattern of large and small callous spots and dots; mtg VII elevated posteriorly in female; deltg II+III completely fused, spiracles II ventral, III���IV sublateral, V���VII lateral on dorsally reflexed vltg V���VII and visible from above; ptg VIII dentiform. Venter. Pro-, meso- and metasterna fused, flattened medially, smooth. Thoracic sterna with conical processes pointing to coxae. Etymology: The generic name is composed of the Latin prefix oblongo - formed from the adjective oblongus, - a, - um, referring to the oblong habitus of the only included species, and the latinized Greek noun coris meaning bug. Gender masculine.

Variation. The two specimens from Yunnan, Pingbian, Daweishan share all essential characters of T. montana sp. nov., but show slight differences in minor structures (e.g. slightly longer antennae, somewhat wider antenniferous tubercles, postocular lobes more granulate, compare Figs 10, 12). The Daweishan mountains are located about 108 km distant from Huanglianshan and are not directly connected. These records are presently classified as T. montana sp. nov., but not included in the type series, as it cannot be excluded that the species from Daweishan represents an endemic taxon, which needs to be tested by molecular data and dissection of genitalia. Etymology. The species name, montanus (- a, - um), is the Latin adjective referring to the mountainous region of Yunnan where it occurs. Distribution.

Cathaycoris gen. nov. Type species. Cathaycoris bibulbosus sp. nov., here designated. Description. Head about as long as wide across eyes; genae produced over clypeus, cleft at middle; antenniferous lobes short and blunt; antennae about 1.7 times as long as width of head, segment I thickest and longest, the following thinner and shorter; eyes globose, not inserted in head; postocular lobes with lateral tooth, then converging to neck. Rostrum arising from a slit-like atrium, shorter than head. Pronotum about twice as wide as long; collar large, triangularly produced posteriorly, laterally separated from anterolateral angles by an incision; disk with 2(1+1) smooth callosities, lateral sclerites produced anterolaterally, lateral margin concave, posterior margin sinuate, delimited by a transverse carina, raised at humeri. Mesonotum consisting of a T-shaped scutellum-like, median, posteriorly elevated sclerite, which is fused to 2 (1+1) oval lateral expansions, interpreted as wing pad rudiments; posterior margin of mesonotum fused to metanotum, both delimited by a deep transverse sulcus. Metanotum. The 2 (1+1) sclerites situated in the lateral margin of the median scutellar projection of mesonotum are of polygonal shape, their surface being irregularly rugose; fused to mtgI, its fusion line marked by a thin suture. Mtg I+II fused without being delimited by a visible fusion line, of trapezoidal shape; mtgI strongly elevated at middle into 2 (1+1) granulate humps, higher than adjacent median mesonotal elevation; mtg II sloping posteriorly to transverse suture separating it from tergal plate; surface except humps deeply impressed. Abdomen. Tergal plate with large median elevation highest on mtg IV+V sloping laterally; deltg II+III fused, triangular, anteriorly reaching mesonotum; deltg III–VII separated by sutures; lateral margin with dorsally reflexed vltg V–VII visible as lateral expansions on deltg V–VII; tergite VII strongly raised in male for accommodating the pygophore. Venter. Prosternum with a median ridge, meso- and metasternum and mstII flat at middle, tooth-like projections directed to coxae not developed; surface of pleural regions rugose, that of sternites III–VII smooth and shiny at middle, rugose laterally of lateral apodemes; spiracles II ventral, III–IV sublateral close to lateral margin and slightly visible from above, V–VII lateral on dorsally reflexed vltg V–VII and visible from above, VIII terminal on ptg VIII; sternite VII of male bears a large glabrous round tubercle, produced posteriorly below the reflexed vltg VII and visible from above. Legs long and slender, unarmed, claws with thin pulvilli. Differential diagnosis. Apterous, medium sized; surface of body and appendages are granular and rather mat, tergal plate is glabrous except the median elevation; coloration is black. Distinguished from other genera by sharing the conspicuous T-shaped mesonotum as follows. There are only three apterous genera of Oriental Carventinae sharing the triangularly produced, T-shaped scutellum-like mesonotum extending to mtgI – Apteraradus Drake, 1957 from Malaysia, Thailand, Vietnam and Sunda Islands, Taiwanaptera Heiss & Nagashima, 2008 from Taiwan and Japan, and Parataiwanaptera Heiss, 2010 from Vietnam. Cathaycoris gen. nov. differs from the preceding genera at first glance by the high median elevations on mesonotum, mtgI and tergal plate (which are flat in the other genera), by the shape of pronotum, and the distinct lateral tooth of the postocular lobes. Etymology. Refers to ‘ Cathay ’ the ancient name for China used by the famous European traveller Marco Polo when returning to Venice in 1295 and ‘ coris ’, the Greek word for bug.

Pronotum less than three times as wide as long at midline; collar very narrow, granular; anterolateral lobes strongly produced forward, lateral margins sinuate, subparallel at humeri, posterior margin convex; fore lobe with a median sulcus flanked by 2 (1+1) ovate callosities, followed laterad by 2 (1+1) prominent, sublateral conical tubercles; hind lobe with 2 (1+1) setigerous tubercles posterolaterally. Mesonotum. Scutellum large, subtriangular, apex widely rounded, disk with an anterior median high tuberculate bulbous elevation; hemelytra reduced to small oval wing pads laterad of scutellum, lateral margins raised, beset with setigerous tubercles; posterior margins rounded. Metanotum and abdominal tergum I fused together, forming narrow transverse plates, no fusion line discernible, divided into 2 (1+1) plates by scutellum, separated from mtg II by a distinct transverse suture, posterior margin trisinuate. Abdomen. Mtg II consisting of 2 (1+1) small triangular plates separated by an anteriorly produced tergal plate, the latter of pentagonal shape with a median elevation on mtg III���VI, lateral parts with shallow depressions; disk of mtg VII of female with two conical tubercles medially; deltg II���VII separated by sutures, surface granulate, posterior margins with conical tubercles; lateral margins of deltg II���VI slightly sinuate (Fig. 1). Venter. Sterna III to VI raised along posterior border, depressed along anterior border; lateral plates with shallow pits; spiracles II���VII ventral, VIII lateral (Fig. 3). Legs slender, without spines; trochanters distinct. Distribution. China: Yunnan. Etymology. The generic name refers to the general similarity of the new genus to Wuiessa Hsiao, 1964. Discussion. The new genus shares the conspicuous anteriorly produced tergal plate with the abovementioned brachypterous Oriental Mezirinae genera Lophocoris and Wuiessa and the micropterous genus Stipesoculus. Lophocoris is easily distinguished by different head structure with non-stylate eyes, lateral margins of pronotum with two finger-like projections, a prominent round elevation on mtg III���IV and posterolateral angles of deltg II��� VII laterally angulately produced. Stipesoculus differs from the new genus by its extremely stylate eyes, its micropterous condition, and the triangular scutellum with acute apex. Brachypterous Wuiessa species are highly similar, but distinct at generic level, differing from Pseudowuiessa gen. nov. in their shorter genae, eyes not being stylate, postocular lobes with a lateral tooth, and anterior pronotal disk with two median conical tubercles., Published as part of Shi, Kai, Bai, Xiaoshuan, Wu, Zhiyi, Heiss, Ernst & Cai, Wanzhi, 2016, Pseudowuiessa, a new genus of brachypterous Mezirinae (Hemiptera: Heteroptera: Aradidae) from China, pp. 146-150 in Zootaxa 4158 (1) on page 147, DOI: 10.11646/zootaxa.4158.1.10, http://zenodo.org/record/256330, {"references":["Hsiao, T.

Paramorphocoris Bai & Heiss, gen. n. Type species: Paramorphocoris henanensis Bai & Heiss, sp.n. Diagnosis. Apterous. Medium sized. Body elongate ovate. Dorsal and ventral surfaces partly covered by grayish incrustation of unique pattern, only lateral borders with few short bristles. Head longer than width across eyes; genae slender, produced over clypeus; antenniferous tubercles stout, conical, apically pointed; eyes small, semiglobose, with convex face; postocular lobes anterolaterally subparallel with some distinct tubercles, converging posteriorly to constricted neck; vertex and clypeus together forming a median ridge; antennae long and slender, first and third segments of subequal length, second shortest, first stout and clavate, second and third cylindrical, fourth fusiform; rostrum arising from a slit-like atrium, not reaching limits of rostral groove. Pronotum attenuated anteriorly, anterolateral angles protruding anteriorly beyond collar, disc with narrow medial groove. Meso- and metanota medially fused to narrow, high longitudinal ridge strongly constricted at middle and flanked by deep depressions, laterally separated by furrows, metanotum separated by furrows from mtg I, mtg II and triangular fused deltg I+II; lateral margins of thoracic segments incrassate, deeply cleft between pro-, meso-, and metanota. Mtg I separated from mtg II by a furrow. Tergal plate of fused mtg III-VI pentagonal. Tergite VII strongly elevated posteriorly (Fig. 2) Thoracic sterna with processes pointing to coxae. Legs long and slender, without spines trochanters fused to femora. Distribution. China. Etymology. The generic name reflects the similarity to Morphocoris, >para Remarks. General habitus, head and thoracic structures of the new genus resemble those of the Oriental genus Morphocoris Kormilev 1980 (Kormilev 1977 (as Glyptomorpha); Heiss 1982), which comprises 3 species from Thailand, Malaysia, and India. Compared with a male paratype of Morphocoros thailandicus in the collection of the co-author (EH) (no female specimen has ever been illustrated), the latter is distinguished from Paramorphocoris henanensis gen. et sp. nov. by a much wider and less constricted median ridge of meso- and metanotum without a longitudinal sulcus, by the very deep oval lateral excavations of metanotum, the deeper median depression of mtg I+II showing 2 longitudinal carinae at its bottom on mtg II, the straight anterior margin of the tergal plate, and the deep median excavation on mtg III in continuation of that of mtg I+II flanked by raised margins. The elevations and deep cavities cannot be recognized from Kormilev’s 1977 only illustration of this species (p. 618, Fig. 19).
