Dinarippiger discoidalis comb. nov. —past and future research Our study establishes the basis for future research on the genus Dinarippiger gen. nov. by presenting a comprehensive overview of the D. discoidalis comb. nov. occurrence in the Dinaric Alps. Special attention was given to the syntopic occurrence of D. discoidalis comb. nov. and Ephippiger species. At the present moment, we know that in several localities in Slovenia, Croatia, and Bosnia & Herzegovina the species co-occurs with E. ephippiger, a central European and Balkan species. In another part of its distribution, i.e., in Istria and Primorska region of Slovenia, D. discoidalis comb. nov. occurs syntopically either with another species of the genus Ephippiger, Alpine E. persicarius, or with a hybrid population of E. ephippiger x E. persicarius. This could be an interesting biogeographical case that requires further attention, as E. ephippiger and E. persicarius could be two subspecies of a single species, which would provide further confirmation that Ephippiger is an Apennine genus whose representatives spread to Eastern Europe relatively recently across the Western Balkans or along the northern banks of the Sava River. The area between Slovenia and Croatia is a well-known glacial micro-refugium (Taberlet et al. 1998, Joger et al. 2007, Jablonski et al. 2017, Wang et al. 2022) due to its contact with the Alps, the Dinaric Alps, the Pannonian basin, the Adriatic coast, and the Po region, harbouring ice-free habitats during the last glaciation. In many groups of plants and animals, these areas represent either the center of dispersal or the secondary contact regions (Surget-Groba et al. 2002, Brus 2010, Dufresnes et al. 2020, García et al. 2020). Dinarippiger discoidalis comb. nov. does not hybridize with any of the Ephippiger species in the areas of sympatric occurrence. Another interesting biogeographical and phylogenetic question is the presence of a single, highly variable species within the newly established Dinarippiger gen. nov. or several distinct species with more restricted distributions and currently undefined diagnostic traits. Many authors have tried to assess the intraspecific variability of D. discoidalis comb. nov., but have failed in reaching a definite conclusion (e.g., Fieber 1854, Krauss 1879). Previous authors have focused mostly on body size (Fieber 1853, Krauss 187), the number of inner and outer spines on the hind tibiae (Werner 1920), or calling song traits (Gomboc & Šegula 2014). Werner (1920) did not manage to find any consistent differences among D. discoidalis comb. nov. populations and noted that the substantial overlaps in trait variability could be the evidence of a single highly variable species. However, in the same study, Werner (1920) noted the presence of a northern smaller race and a southern larger race, but apart from body size no clear differences between the two were found. Geographical variation in body size is, for example, present in Italian Ephippiger cavannai Targioni Tozzetti, 1881, a species characterized by smaller individuals in montane locations and larger ones in the coastal areas (Massa et al., 2012). Galvagni (1956) initially described a separate taxon, E. perforatus tamaninii, which later turned out to be a montane population of E. cavannai. Without a systematic comparison of the individuals from distant and isolated populations, variability within D. discoidalis comb. nov. remains an open question. This issue is illustrated by a photograph of a peculiar male (Fig. 13) from Vremščica Mt. (Slovenia), serving as a reminder that future studies have to include a phylogeographical survey, detailed morphometric analyses, as well as comparative morphological and bioacoustic approach.

Genus Dinarippiger Skejo, Kasalo, Fontana et Tvrtković gen. nov. Etymology. The generic name Dinarippiger derives from the words “ Dinara ”, the mountain between Croatia and Bosnia & Herzegovina after which the Dinaric Alps were named, and “ Ephippiger ”, the name of the genus type species has belonged to hitherto. The word “ ephippiger ” originates from the Ancient Greek word ἐφίππιον (ephippion), meaning saddle, and suffix “-ger, -gera, -gerum” meaning “-bearing”, originating from the Latin verb “gero” meaning “to carry”. The word for “saddle” also originates from two words, the adjective ἐπῐì (epí, meaning “on”) and ἵππος (híppos, meaning “horse”). The genus name is of the masculine gender. Type species. Ephippiger discoidalis Fieber, 1853, here designated; type species by original designation, but also by original monotypy. Diagnosis. The new genus is similar to Ephippiger (type species Gryllus ephippiger Fiebig, 1784 = Ephippiger ephippiger) and Uromenus (type species Ephippiger rugosicollis Serville, 1838 = Uromenus rugosicollis) and is intermediate in certain characters. From Ephippiger taxa, Dinarippiger gen. nov. can be separated by the following characters: 1) Red coloration of occiput directly adjacent to the prozona of the pronotum (black coloration in Ephippiger). 2) Basal color of the tegmina black, with a wide white line just anterior to the caudal margin of the tegmen (basal color uniformly brown in Ephippiger). 3) Cerci with bilobate tip, inner lobe almost as developed as the outer one (outer one ostensibly more developed in Ephippiger). 4) Metazona of the pronotum shorter and less elevated than in Ephippiger. From Uromenus taxa, Dinarippiger gen. nov. can be distinguished by the following set of characteristics: 1) Bright red coloration of the occiput (in Uromenus blue, yellow, orange, or reddish, but never vivid red). 2) Large part of the tegmina is visible (in Uromenus tegmina are mostly covered by the pronotum). 3) Tegmina with numerous small black dots on the dorsal margin forming a continuous black line (in Uromenus there are large black dots separated by white areas). 4) Ovipositor is typically long and straight (short and decurved ovipositor in Uromenus), but its length is highly variable among different populations. Furthermore, Dinarippiger gen. nov. males have trapezoidal and bilobate epiproct, while Uromenus and Ephippiger males have rounded or square epiproct, rarely weakly bilobate. In addition to the above-mentioned differences, it is important to note that abdominal tergites in Dinarippiger gen. nov. typically have black and white markings, which are not present in Uromenus and Ephippiger. Visually similar to Dinarippiger gen. nov. is Uromenus annae (Targioni-Tozzetti, 1881) endemic to Sardinia, in which males also have red occiput (in females, however, occiput coloration is dark), short metazona, ornamented abdomen, but short and decurved ovipositor typical of Uromenus, and distinct cerci (compare Buzzetti et al. 2019). Composition and distribution. The new genus includes a single species to date, Dinarippiger discoidalis (Fieber, 1853) comb. nov. inhabiting the karst of Italy, Slovenia, Croatia, Bosnia & Herzegovina, Montenegro, and Albania. The genus inhabits the area between the distribution areas of the genera Ephippiger and Uromenus. Uromenus inhabits the area south of Dinarippiger gen. nov. distribution, with the closest populations in southern Italy, and a single isolated population in Albania (Fig. 3). The distribution area of Dinarippiger gen. nov. borders/ overlaps with that of E. ephippiger in the central part of the Dinaric Alps (nearest known localities of Ephippiger are shown in Fig. 10). In Slovenia and Croatian Istria, the distributions of E. ephippiger or E. persicarius and D. discoidalis comb. nov. may overlap due to the mosaic composition of Mediterranean and continental habitats (Fig. 10)., Published as part of Skejo, Josip, Kasalo, Niko, Fontana, Paolo, Ivković, Slobodan, Tvrtković, Nikola, Rebrina, Fran, Adžić, Karmela, Buzzetti, Filippo Maria, Ćato, Sebastian, Deranja, Maks, Gomboc, Stanislav, Scherini, Roberto, Škorput, Jadranka, Veenvliet, Paul, Vuković, Marijana, Lemonnier-Darcemont, Michèle, Darcemont, Christian & Heller, Klaus-Gerhard, 2023, Dinarippiger gen. nov.

Macroscirtus can be separated from the other genera of Mecopodinae by the following combination of characters: fastigium of vertex about 2 times broader than antennal scapus; prosternum armed; tegmina longer than pronotum but not reach mid of hind femora; hind wings reduced or nearly missing. Male tegminal stridulatory organs missing except possibly in M. acutipennis, which has at least asymmetrical tegmina.

Cosmoderus femoralis Sjöstedt, 1901 Material examined: 3 males [CH8626 (SR, TI, CHR), CH 8627 (SF, TI, CHR), CH8628 (CHR)], CAMEROON, 2018, obtained alive from P. Grabowitz, Cologne. Bioacoustics. The tegmina of Cosmoderus femoralis males show the typical Hetrodini shape (Fig. 2). The left file carries 65 relatively small teeth (Table 1; Fig. 4), much more than in the species described above. The recorded male produced its calling song only at night. In the beginning it made crescendoing series of syllables lasting a few seconds, but these sequences quickly became longer ending in very long trills (Fig. 5A, 8A; longest recorded uninterrupted songs 46 and 66 minutes). The spectrum of the song is typical for Hetrodini with the peak at 16 kHz (Fig. 6). Genitalia. The genitalic sclerites consist of a large, central, triangular, basal part (titillator) with a very short rectangularly-bent tip and two smaller lateral elements (Fig. 9A). Chromosomes: 2n = 25 (24 + X0), FN = 29; pairs 1 and 2 submetacentric (= bi-armed), 3–12 and X chromosome acrocentric (3 males); thin C-positive paracentromeric bands in all of the chromosomes and an interstitial one in the first pair of autosome (Fig. 12A)., Published as part of Heller, Klaus-Gerhard, Chobanov, Dragan, Warchałowska-Śliwa, Elżbieta & Hemp, Claudia, 2022, Review of song patterns and sound production in armoured ground crickets (Orthoptera: Tettigoniidae: Hetrodini) with karyological data and taxonomic notes, pp. 451-481 in Zootaxa 5120 (4) on page 464, DOI: 10.11646/zootaxa.5120.4.1, http://zenodo.org/record/6392707, {"references":["Sjostedt, Y.

Acanthoplus longipes (Charpentier, 1843) References: Conti & Viglianisi 2005, Kowalski & Lakes-Harlan 2011, Kowalski & Lakes-Harlan 2013 Bioacoustics. Acanthoplus longipes and A. discoidalis possess stridulatory files with unusually few teeth (fewer only in Anepisceptus horridus) and quite large intervals between the teeth. Their calling songs look relatively complicated because they consist of two groups of impulses which are repeated again and again resulting in a trilllike structure (Fig. 7; based on data and figures taken from literature). In our interpretation, both groups together should be considered as one syllable produced during one closing movement with a short break in the middle (e.g., in Leptophyes lisae; Heller 1988). This idea is supported by the observation that in the first group the impulses are typically increasing in amplitude and in the second decreasing (Fig. 7; not the case only in 7C). Both species differ distinctly in the syllable repetition rate with A. longipes singing faster than A. discoidalis. The differences in SRR between the two recordings of A. discoidalis (Conti & Viglianisi 2005, Kowalski & Lakes-Harlan 2013) result very probably from the different temperatures during recording. A. longipes females made phonotaxis mainly to the species-specific song pattern, while A. discoidalis females were attracted to a wider spectrum of song models (Kowalski & Lakes-Harlan 2011)., Published as part of Heller, Klaus-Gerhard, Chobanov, Dragan, Warchałowska-Śliwa, Elżbieta & Hemp, Claudia, 2022, Review of song patterns and sound production in armoured ground crickets (Orthoptera: Tettigoniidae: Hetrodini) with karyological data and taxonomic notes, pp. 451-481 in Zootaxa 5120 (4) on pages 461-462, DOI: 10.11646/zootaxa.5120.4.1, http://zenodo.org/record/6392707, {"references":["Charpentier, T. de (1843) Orthoptera descripta et depicta [1841 - 1845].

Hetrodini Brunner von Wattenwyl, 1878 stat. nov The 14 genera of Hetrodini have been divided into five groups (subtribes): Acanthoplina Ebner & Beier, 1964, Anepisceptina Schmidt, 1998, Enyaliopsina Weidner, 1955, Eugastrina Karsch, 1887 and Hetrodina Brunner von Wattenwyl, 1878. Despite some reservations, we follow this conventional classification. Surprisingly, the internal genitalic organs of the males did not attract much attention (except in Enyaliopsis; Glenn 1991) in taxonomic studies. This may be partly due to the fact that many studies were made before the importance of this character was known, and the titillators are difficult to prepare, but partly also because in some genera these structures do not seem to be sclerotized. In Eugaster and Eugasteroides we could not find distinct sclerotized elements, whereas, in other genera they are quite large (see Specific part). ......continued on the next page TABLE 1. (Continued) § Glenn 1991 $ Conti & Viglianisi 2005 & Kowalski & Lakes-Harlan 2013 * Naskrecki & Guta, 2019 # Schmidt 1990 % Grzeschik 1969 Bioacoustics Male tegmina. As in almost all tettigonioids, Hetrodini produce their songs by rubbing the stridulatory file on the lower side of the left tegmen against the scraper, the amplified edge of the right tegmen. In all species studied, left and right tegmen were quite similar in shape (Fig. 2). They do not show structures adapted for sound propagation or amplification like e.g., glossy mirror cells. Species differ in the size of the tegmina and in details of the venation but are in general quite uniform (Fig. 3). Stridulatory files. In all specimens studied by us and by others (Grzeschik 1969) the left tegmen was nearly always placed above the right tegmen as it is typical for tettigonioids. In Eugaster only 4 out of 237 males had a reversed position, but also these males were able to sing (Grzeschik 1969). The left file carried also more and stronger teeth and was longer than that of the right tegmen (Grzeschik 1969, Glenn 1991). The tooth number in the left file varied between 20 and 65, the length of the file between 1.4 and 4.3 mm, and the intervals between the teeth in the middle of the file between 32 and 136 µm (Table 1; see Fig. 4 for examples). The intervals between the teeth were distinctly larger in the two Acanthoplus species than in all other investigated species. Amplitude pattern. All Hetrodini species studied until now produce non-resonant songs with each syllable consisting of a series of distinct impulses (Fig. 7, 8, 10; see also e.g., figures in Kowalski & Lakes-Harlan 2013). However, in recordings containing many echoes these impulses can often not be recognised as separated units. According to the grouping of the syllables, the songs can be subdivided into three categories. Some species produce very long (sometimes lasting more than one hour), uninterrupted sequences of syllables (trilling species; Fig. 5A). Other species have also songs containing series of syllables lasting several seconds, but these sequences and their intervals are typically variable in duration. There is a more or less continuous transition from nearly trill-like sequences (Fig. 5B 1) to short groupings or even single series separated by large gaps (Fig. 5B 2, 3). The third group of species differs clearly from the preceding ones showing short groups of syllables (echemes) with intervals in a similar range, both quite constant in their duration (Fig. 5C). The echemes contained 7 to 31 syllables depending on the species. The syllable repetition rate of the species studied here varied between 7 and 44 Hz (Table 2; all song types). In all species studied, there seems to be only one type of hemisyllable; the sound is probably produced during the closing movement of the tegmina only. Accordingly, the steep side of the teeth is directed towards the wing edge (in SEM photos of Conti & Viglianisi 2005). Opening hemisyllables are missing or are very weak (Fig. 7I, 8G). Spectra. The power spectra of the male songs show one broad peak with the maximum always in the high audio range, between 9 and 19 kHz (Fig. 6, Table 2). The bandwidth 10 dB below peak ranged from 4 to 12 kHz. In interspecific comparisons, there were no obvious correlations between any morphological characteristics (body size, pronotum length, tooth number, file length, inter-tooth intervals) and peak frequency (r 2 =0.01–0.09; p=0.11–0.63) or bandwidth (r 2 =0.00–0.08; p=0.33–0.68; see Table 1 and 2). Song intensity. The loudness of the song is an important parameter that determines the range of the song to conspecifics and predators, depending also on spectral characteristics of the sounds and of the ears of the receivers. It is rarely measured because the procedure requires special equipment. In Hetrodini, Kowalski & Lakes-Harlan (2010) presented data for one species, and here another three are added (Table 3; all measured or calculated for a singing male in 1 m distance). Our new data may have a tendency for underestimating the loudness because the equipment was not sensitive for ultrasonic frequencies (>20 kHz). The much lower values of Acanthoplus longipes were obtained with equipment sensitive to 10 kHz only according to its datasheet. Syntopic occurrences. Despite the large number of (sub)species described there is little information which of these forms do coexist at a certain place and how they might manage to live together. In Table 4 we present all of the surprisingly few examples of syntopic occurrences we could find together with data on body size and song characteristics of the species involved. Chromosomes. A comparison of the karyotype of eighteen Hetrodini species/taxa revealed differences in the chromosome number (2n), the chromosome morphology (including X and Y chromosomes), the fundamental number of chromosomes arms (FN), the sex chromosome system, and C-banding pattern (C-band/C-block). The information presented applies to both new and previously published data (Fig. 13; Mbata 2005, Warchałowska-Śliwa & Bugrov 2009, Grzywacz et al. 2015, Warchałowska-Śliwa et al. 2015). The examined males had from 29 to 17 chromosomes and one of two sex determination systems: the classical X0 as well as neo-XY. Males of four Hetrodini species belonging to two different subtribes (Enyaliopsina: Enyaliopsis bloyeti; Eugastrina: Eugaster —2 species and Eugasteroides loricatus) have a similar karyotype characterized by 2n = 29 and acrocentric chromosomes including the X chromosome, the largest element in the set. In Hetrodes pupus (Hetrodini), Enyaliopsis ephippiatus, Enyaliopsis spec. 2 Mpwapwa and Gymnoproctus (both Enyaliopsina) the complement is reduced to 2n = 27 (all chromosomes acrocentric) as well as in Cosmoderus (Enyaliopsina) and Acanthoplus (Acanthoplina) to 25 with one or two bi-armed pairs of autosomes and an acrocentric or bi-armed X chromosome. The lowest chromosome number, 2n = 17 was found in Spalacomimus magnus (Eugastrina) with five bi-armed autosomes. All the abovementioned taxa show X0 sex determination system. On the other hand, a neo-XY sex chromosome mechanism was also observed in two subtribes: in the genera Enyaliopsis [E. jennae (2n = 28) and E. carolinus (2n = 26)] and in Spalacomimus [S. talpa and S. verruciferus (2n = 24) with different morphology of the neo-sex chromosomes]. After C-banding, chromosome regions showed quantitative variation in constitutive heterochromatin blocks among species and genera.

Spalacomimus spec. near verruciferus S. near verruciferus differs only slightly morphologically from S. verruciferus distributed further north in Tanzania. In S. verruciferus the “warts“ on the 9th abdominal tergite are conspicuous structures while in S. near verruciferus these structures are low bumps or ridges rather than blade-like warts. Further, the posterior margin of the subgenital plate is differently shaped between these two species. Otherwise, in size and body shape, and the spination of the pronotum, both species are very similar.

Enyaliopsis ephippiatus (Gerstaecker, 1869) Enyaliopsis spec. 1 (near ephippiatus) E. ephippiatus is known only from Northern Tanzania and southern Kenya. Its type locality (Ugono in Tanzania) could not be localized by Glenn (1991), but refers to a mountain range now more commonly called North Pare Mountains (formerly Ugweno Mts.). When analyzing the songs it turned out that here two species exist, mainly differing in song (see below). Enyaliopsis ephippiatus has song type A, Enyaliopsis sp. 1 (near ephippiatus) song type B. Both song morphs are similar in titillator shape but differ in geographic range, morph A more northern than morph B. E. near ephippiatus from the South Pare Mts, situated adjacent to the North Pare Mts and E. ephippiatus from the North Pares and the Mt Kilimanjaro area are morphologically very similar. However, male specimens of E. ephippiatus have a narrower pronotum than E. near ephippiatus males. Females of E. ephippiatus are generally larger but more slenderly built than females of E. sp. 1 (near ephippiatus).

Tegmina (Fig. 3), stridulatory file (Table 1) and spectrum of the song (Fig. 6) do not show large differences to the typical Hetrodini pattern. The file of the holotype (photo in OSF) is very similar to that of a male from group A. The calling song consists of long series of syllables (song type B 3 in Fig. 5). These series are often produced in small groups with the first series longer than the following (9 s vs. 4–5-s). The two song types differ in SRR by a factor of about two; 35–45 Hz at 20–24ºC in type A (n = 8 specimens) and 20–24 Hz at 21–25ºC in type B (n = 3 specimens; Fig. 8D, E; see Table 2). Genitalia. According to Glenn (1991), the titillator of the holotype is lost. All of our four studied males show a slender, relatively long central part of the genitalic sclerites (Fig. 9D, E), ending in a blunt tip with a hook on both sides. In general shape, it is thus similar to the other species of the obuncus group (see Glenn 1991), but differs by missing additional tubercles on the tip of the titillator beside the lateral hooks. Chromosomes. The karyotypes of both species are very similar: 2n = 27 (26 + X0) male and 28 (26 + XX) female, FN = 29/30; pair 1 metacentric, 2–13 and X chromosome acrocentric (4 males, 1 female and 1 male described earlier [Grzywacz et al. 2015]: CH 7737); thick C-positive in large/medium and thin C-bands in short-sized pairs paracentromeric bands, thick distal C-block in pairs 3, 4 and the X chromosome (Fig. 12D)., Published as part of Heller, Klaus-Gerhard, Chobanov, Dragan, Warchałowska-Śliwa, Elżbieta & Hemp, Claudia, 2022, Review of song patterns and sound production in armoured ground crickets (Orthoptera: Tettigoniidae: Hetrodini) with karyological data and taxonomic notes, pp. 451-481 in Zootaxa 5120 (4) on pages 466-467, DOI: 10.11646/zootaxa.5120.4.1, http://zenodo.org/record/6392707, {"references":["Gerstaecker, A.

In a very detailed morphological study, Grzeschik (1969) combined the large variety of named forms into two species with several subspecies each.

The species is bioacoustically quite similar to S. stettinensis. The echemes seem to be shorter by a factor of two (only 19 syllables per echeme) and the echeme repetition rate is correspondingly faster (Fig. 10H; see Table 2). Genitalia. In size, the genitalic sclerites (Fig. 11E) are similar to that of S. stettinensis and S. talpa. The main part of the titillator, however, is not broad, but triangular and the lateral sclerites are intermediate between the other two species in size.

Eugaster spinulosa (Johansson, 1763) Material examined: 4 males (SR), MOROCCO, N Marakesh, 21.05.2013, N 31.88001, W 007.94920, 568–700 m, leg. Chobanov (spinulosa brevispina) Re ferences: Grzeschik 1969, Arias et al. 2012 Bioacoustics. All specimens of Eugaster recorded previously (Grzeschik 1969, Schmidt et al. 1997, Arias et al. 2012) and by us, showed a calling song consisting of a series of short echemes (Fig. 5C 2; Fig. 10A, B; see Table 2). Each echeme contains between 8 and 12 (once 14; see Grzeschik 1969) syllables. The SRR in these recording varies between 21 and 53 Hz at different and often unknown temperatures. For ERR fewer data are available (1–3.4 Hz) but here a strong and quite strict relationship with temperature is documented with a factor of about four between 15 and 35ºC (Nielsen 1974). So at present in our opinion there are no data that prove song differences between any named forms. The number of teeth in the stridulatory files is also quite similar between subspecies/species, ranging from 41.4 to 48.0 (means with n =5–30; Grzeschik 1969, p. 103). Genitalia.

Gymnoproctus spec. Only one male and one female were obtained from this new species. Oddly, the male is very small in body size. The posterior part of the pronotum is inflated. As in G. rammei the lateral sides are armed with long and slender spines. Also, the female is comparatively small, smaller than females of the morphologically similar G. rammei. G. similis occurring in the Singida area is similarly stout and large as G. rammei but has a less spiny pronotum, the spines having a rather stout base.
