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.

Genus Macroscirtus Pictet, 1888 Synonym Macroscyrtus Bolívar, 1893. The name Euthypoda Karsch 1886 with the type species E. difformis, designated by monotypy in Karsch 1892, is a junior synonym of Vetralla [quadrata] Walker 1869 (Kirby 1891). The type species designation of E. acutipennis by Kirby (1906) is invalid. Diagnosis. 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.

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.

Gymnoproctus sculpturatus Schmidt, 1990 References: Schmidt 1990, Schmidt & Mungai 1996 Bioacoustics. The calling song (Fig. 7E) is quite similar to that of G. rammei and consists of long series of syllables (song type B in Fig. 5; see Table 2). Genitalia. According to Schmidt & Mungai (1996), the genitalic sclerites are only weakly sclerotized and easy to find in old males only. The titillator is triangular, broad in its base, and continuously tapering to the tip., 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 471, DOI: 10.11646/zootaxa.5120.4.1, http://zenodo.org/record/6392707, {"references":["Schmidt, G.
