Roeseliana azami (Finot, 1892) Figs. 1b, 3d, 5e, 5f, 7e, 8c, 11, 23h Finot, 1892. Bull. Soc. entomol. Fr., 61: xxxv (Platycleis azami); type locality and depository: France, between Cogolin and La Foux, Var (MNHN, Paris). Material examined. France, Var VI.1888, Azam (1♁, 1♀ syntypes) (MNCN); France, Var, Azam (1♁, 1♀) (NMW); France, Crau, Bouches du Rhone VI.1967, M. Descamps (1♁, 1♀) (MCR, coll. P.

R. azami is characterized by the incision of the female subgenital plate. Nadig (1961), Harz (1969) and Massa et al. (2012) considered R. azami the nominate subspecies with minor as other subspecies, while Ĝtz (1969) moved it to subspecies of R. fedtschenkoi, Defaut (1999, 2001) followed Ĝtz’s opinion, Puissant & Voisin (1999), Voisin (2003) and Massa & Fontana (2011) considered it as a valid species. Male titillators have only few large spines in their half apical apex and their tip is less curved and stouter than that of R. azami minor and R. brunneri (Figs. 5e, 5f), the supragenital plate and the cerci of the male and the subgenital plate of the female are reported in Figs. 7e and 8c. The 10 th tergite of the male has a very long, broad and triangular processes (in R. brunneri processes are very large and separated by a wide incision), tooth of cerci short, rounded and placed in the last fourth (as in R. brunneri; in R. roeselii they are longer, placed in the last third and are more pointed); titillators of R. azami are similar to those of R. brunneri (folded as a hook), while those of R. roeselii show a very different shape (straight with apical spines) (cf. Fig. 5); in addition, the female subgenital plate of R. azami is as large as long, incised for half the length and its lobes are rounded (similarly to that of R. brunneri), while that of R. roeselii is laterally enlarged and its lobes are pointed (cf. also Massa & Fontana 2011). Fully-winged specimens are unknown. See also Tables 2 and 4. Distribution. Region du Var (Mediterranean France).

Genus Roeseliana Zeuner, 1941 Morphological analysis Characters of the genus Roeseliana The genus Roeseliana was described by Zeuner (1941), who named it after the Austrian entomologist August Johann R̂sel von Rosenhof. However, several authors preferred to maintain Roeseliana as subgenus of the genus Metrioptera Wesmael, 1838. More recently, Massa & Fontana (2011) carried out a revision of Platycleidini and raised again Roeseliana to generic level. According to previous authors (Zeuner 1941; Massa & Fontana 2011), these are the characters of the genus: head slightly broader than long, ratio maximum width/length of head (from vertex to clipeus): 1.2–1.3. Brachypterous, rarely holopterous, pronotum flat, just depressed, margins rounded, humeral excision just evident, keel present in the metazona; ♀ subgenital plate large, bilobate, at the sides not touching the ovipositor; ovipositor short and clearly curved, somewhat angular at 1/3 from the base; ♀ VIIth sternite modified or not; hind femora/pronotum length ♁: 2.7–3.5, ♀: 2.7–3.6; ♁ Xth tergite with very broad processes separated by an incision, long cylindrical cerci, with a pre-apical inner spine. Colour of lateral lobes of the pronotum greyish bordered with a whitish stripe. Diagnosis. Tenth tergite of male with very broad anal segment, rounded cerci and short ovipositor are useful characters to separate Roeseliana from Metrioptera and Bicolorana Zeuner, 1941; with the latter Roeseliana shares the female subgenital plate not touching the ovipositor. Ovipositor— Figs. 1–2, Table 2 The shape of the ovipositor is fairly variable, but we could find taxa/populations with fine ovipositor (R. pylnovi, R. roeselii, R. azami minor from Lombardy, Piedmont and Emilia-Romagna, R. ambitiosa), and those with deeper ovipositor (R. azami, R. azami minor from Tuscany and Marche, R. brunneri and R. bispina). However, the ovipositor angle resulted also variable in the different taxa/populations, smaller in R. pylnovi, R. oporina, R. azami, R. azami minor from Lombardy, Piedmont, Emilia-Romagna and Tuscany, R. brunneri and R. bispina, bigger in others, namely R. roeselii, R. azami minor from Marche and R. ambitiosa. Stridulatory file— Fig. 3, Table 2 We describe preliminary the stridulatory file of different taxa/populations, that are very similar in their structure (Fig. 3). The length is ca. 1.2 mm, while the depth may range from 0.20 to 0.35 mm. Stridulatory file is a little arched, the total number of teeth ranges between 40 and 80 (R. brunneri: ca. 70–80 with 15 central larger; R. azami minor from Tuscany: ca. 50 with 15 central larger; R. azami minor from Piedmont: ca. 40, with 15 central larger; R. azami: ca. 45, more or less of the same size; R. roeselii: ca. 50, with 12–13 central larger teeth; R. ambitiosa: ca. 50 with at least 40 teeth of more or less the same size and a few very small teeth in the proximal part; R. bispina: ca. 60, more or less of the same size; R. pylnovi: ca. 50, with 12–13 central larger). Generally, the stridulatory file in its proximal part bears very small teeth (about 15–20), dense, decreasing in size and evenly spaced, the central part is composed of ca. 12–15 widely spaced larger teeth (with some exceptions, like in R. azami, R. bispina and R. ambitiosa), the distal part is composed of about 8–10 very small teeth. The differences are noted in Table 2. Female subgenital plate— Figs. 8, 9, Table 2 The ratio length to width of the female subgenital plate resulted to be maximum in R. pylnovi (2.8), followed by that of R. roeselii (2.0–2.1), R. azami minor from Marche (2.1–2.2), R. oporina (1.8), R. azami minor from Lombardy, Piedmont and Emilia–Romagna (1.8–2.2), R. brunneri (1.7–1.9), R. azami (1.7), R. azami minor from Tuscany (1.7), R. bispina (1.7) and R. ambitiosa (1.5). However, other differences in the shape of the apical tips of the subgenital plate are evident., Published as part of Massa, Bruno, Tagliavia, Marcello, Buzzetti, Filippo Maria, Fontana, Paolo, Carotti, Giovanni, Bardiani, Marco, Leandri, Fausto, Scherini, Roberto & Verde, Gabriella Lo, 2023, A taxonomic revision of the Palaearctic genus Roeseliana (Orthoptera: Tettigoniidae: Tettigoniinae: Platycleidini): a case of ongoing Mediterranean speciation, pp. 351-400 in Zootaxa 5270 (3) on pages 356-357, DOI: 10.11646/zootaxa.5270.3.1, http://zenodo.org/record/7859886, {"references":["Zeuner, F.

Roeseliana oporina (Bolívar, 1887) Figs. 2d, 5k, 6c, 8d, 10, 23g Bolívar, 1887. An. Soc. Espan. Hist. Nat., 16: 108 (Platycleis oporina); type locality and depository: Spain, Cuenca, Uclés near Saelices, Castillo de Castillejo (MNCN, Madrid). Material examined. Spain, Uclés (lectotypus ♁) (MNCN). Remarks. R. oporina was described in Platycleis, but Zeuner (1941) moved it to Roeseliana; Harz (1969) listed it in Metrioptera, subgenus Roeseliana, Massa & Fontana (2011) in Metrioptera. Only recently R. oporina was rediscovered and described again by Gutiérrez-Rodríguez & García-París (2016), who established definitively that it is belongs to Roeseliana. Morphological characters suggest that it is related to R. azami, but not to R. roeselii. R. oporina has male titillators not much apically hooked, with only small apical spines, the female subgenital plate is similar to that of R. azami, but male cerci are a little similar to those of R. roeselii. The lectotype has tegmina covering the abdomen, while specimens depicted by Gutiérrez-Rodríguez & García-París (2016) are more brachypterous. See also Tables 2 and 4. Distribution.

Roeseliana n. sp. Lemonnier-Darcemont & Darcemont, in press. Figs. 22d, 23d Lemonnier-Darcemont & Darcemont, in press. Zoosystema; type locality and depository: Mazarakia, Epirus, Greece (MNHN, Paris). Remarks. The description of this species has been proposed when we finished our revision and we were not able to examine specimens; however, thanks to the courtesy of Michèle Lemonnier-Darcemont it was possible to examine some photographs and to provide biometrics. Measurements. Male. Body length: 19.5; pronotum: 6.5; tegmina: 9.5; hind femur: 17.5. Female. Body length: 24.5; pronotum: 6.5; tegmina: 7.5; hind femur: 21; ovipositor: 8.5. Male differs from Roeseliana oporina by the shape of cerci and of titillators, from R. bispina by the width of the base of the apical tooth of the cerci, from R. ambitiosa and R. azami by the shape of titillators and the arrangement of their spines, from R. brunneri by the shape of the last tergite. By their last tergite largely indented with narrow and pointed lobes at their extremity, they are however close to R. azami, to R. oporina and to R. ambitiosa. The internal tooth of the male cerci is short and placed at ¾ of the cerci, it is barely wider at its base than at the apex as R. ambitiosa, R. brunneri, R. oporina and R. azami. The shape of titillators is similar to that R. bispina, but with a different number and arrangement of spines. The shape of the female subgenital plate is intermediate between that of R. oporina and R. azami but with a much shallower incision and a less pronounced central keel (Lemonnier-Darcemont & Darcemont in press)., Published as part of Massa, Bruno, Tagliavia, Marcello, Buzzetti, Filippo Maria, Fontana, Paolo, Carotti, Giovanni, Bardiani, Marco, Leandri, Fausto, Scherini, Roberto & Verde, Gabriella Lo, 2023, A taxonomic revision of the Palaearctic genus Roeseliana (Orthoptera: Tettigoniidae: Tettigoniinae: Platycleidini): a case of ongoing Mediterranean speciation, pp. 351-400 in Zootaxa 5270 (3) on page 366, DOI: 10.11646/zootaxa.5270.3.1, http://zenodo.org/record/7859886

Roeseliana fedtschenkoi (Saussure, 1874) Figs. 6e, 10 Saussure, 1874. Mém. Soc. Sci. nat. Antrop. Ethnogr. Univ. Moscou, 11: 45 (Decticus (Platycleis) fedtschenkoi); type locality and depository: Uzbekistan, Maracanclam et prope Bairakum ad flumen Jaxartem (Samarkand, Syr Daria) (syntypus, ZMUM). Found near Samarkand on June 8, 1869 (larva) and May 17, 1871 in Bayrakum. Brown-green or yellowish-green color. The head is wide, smooth; the top of vertex is broad and blunt, on its sides above the eyes there is a horizontal brown stripe, separated or bordered by a yellowish line, extending from the eyes; vertex is decorated with three pale longitudinal lines, from which the lateral lines follow the edges of the brown stripes. The antennae are dark, green at the base. Mesothorax width the same as its length; the upper surface of mesothorax is wide, flat, slightly convex at the front end, slightly concave in the middle; the middle lobe is very weakly expressed, the lateral lobes are blunt; the rear edge is cut off, slightly turned upwards; the folded edge comes onto the lateral lobes of pronotum; the latter is bordered by a whitish stripe and decorated with irregular brown spots (or the area along the lobes and along the edges of the lobes is brown); rear part of side lobes of pronotum is blunt cut. The colour is green-brown or yellow-green. The head is broad and smooth; the apex of the head is broad and obtuse; on the sides, above the eyes, there is a horizontal brown stripe which divides a yellowish stripe or surrounds it, there are three pale lines running along the brown stripe, of these, the lateral ones reach the ends of the brown stripe. Width of the front part of the thorax equal to the length; the upper surface is broad and flat, slightly convex in the fore margin and slightly concave in the middle; the lobe of the middle is not very pronounced, the lateral lobes are a little obtuse, the hind edge is truncated, slightly raised; this raised edge joins with the lateral keels; in the anterior part of the pronotum there is a pale line with irregular brown flecks; the posterior edge of the lateral keels is cut obtusely at the point where they go towards the posterior side of the anterior part of the pronotum. Tegmina red-yellow, rounded at the apex, cover the entire abdomen except its three posterior segments; the veins of the elytra are brown, with the exception of a green “shoulder” vein, which is arcuately curved and gives five brown branches near its middle. The tympanum is poorly developed, the stridulatory file is poorly developed and is covered in the anterior part by the pronotum; the mirror is not closed, it has only the outer vein. The wings are rudimentary. The legs and body are concolourous. The hind femora are adorned with a longitudinal brown stripe. The ventral side of abdomen is pale. The supra-anal plate is incised with an oblong impression in the form of A on its surface; this depression is narrow, rounded-blunt at the apex, surrounded by hairs, has prominent sharp edges; the supra-anal plate is deeply incised at the apex. This notch has almost the same shape as the depression on the surface of the plate; the corners of the edges of the notch continue into triangular tongue-like spines. The cerci are long, somewhat protruding from the stylet-like processes of the subgenital plate; on their apical third, they are each armed with one sausage-like process, which apex is black. The subgenital plate is large, with an impression at its base, equipped with three strongly developed ribs, rounded at the free edge and incised in the form of V. The cerci are long, a little protruding from the plate cavity, in the distal third there is a black spine. Remarks. Saussure (1874) wrote that tegmina cover the entire abdomen, excluding three posterior segments, tegmina of the syntypes cover only one third of abdomen (Fig. 10). In addition, Saussure (1874) compared the species with Platycleis brevipennis (Charpentier, 1825) (currently synonym of R. roeselii), pointing out that R. fedtschenkoi is larger, has shorter tegmina, supra-anal plate of different shape and less developed tympanum. Later, Stshelkanovtzev (1907) recorded another male from Sossyur (Turkmenistan) and described the female from Lake Balkhash (Turkmenistan), pointing out that it was similar to R. roeselii, with tegmina apex less obtuse, shorter ovipositor, bigger size, but the subgenital plate very similar to that of R. roeselii. Thanks to the kindness of A. Gorochov, O. Korsunovskaya, V. Savitsky, and A. Ozerov we were able to examine the photo of the supra-anal plate of the syntype (Figs. 6e, 10), finding that it is very similar to that of R. pylnovi, including the male titillators, apically hooked, but different from R. roeselii, whose titillators are differently shaped. All authors agree with the validity of this taxon, with the exception of Heller (1988), who has considered it synonymous with R. roeselii (see above, R. roeselii). Tarbinsky (1932) considered R. pylnovi synonym of R. fedtschenkoi; indeed, in many museums there are specimens from Caucasian area identified as R. fedtschenkoi. According to Ĝtz (1969), R. fedtschenkoi (vasilii included), R. pylnovi, R. ambitiosa, R. azami, and R. minor constitute a ‘Rassenkreis’, a ring of neighbouring populations that exhibit a pattern of geographical replacement of one type by another. However, he treated vasilii, pylnovi, ambitiosa, minor and azami as subspecies of fedtschenkoi, without having studied specimens of true R. fedtschenkoi. Stolyarov (2005) followed the same arrangement. More recently, Chobanov & Mihajlova (2010) and Iorgu et al. (2013) treated R. fedtschenkoi as a subspecies of R. roeselii. See R. roeselii, Tables 2 and 4. The song of R. fedtschenkoi is presently unknown. Distribution. This species has been described from Uzbekistan, later it was collected in Turkmenistan, and probably it is restricted to the East Asia, while in West Asia and North Europe it is replaced by R. pylnovi and R. roeselii. According to Stolyarov (2005) it should be present also in Azerbaijan, Dashkesan, but specimens from this country could eventually belong to R. pylnovi., Published as part of Massa, Bruno, Tagliavia, Marcello, Buzzetti, Filippo Maria, Fontana, Paolo, Carotti, Giovanni, Bardiani, Marco, Leandri, Fausto, Scherini, Roberto & Verde, Gabriella Lo, 2023, A taxonomic revision of the Palaearctic genus Roeseliana (Orthoptera: Tettigoniidae: Tettigoniinae: Platycleidini): a case of ongoing Mediterranean speciation, pp. 351-400 in Zootaxa 5270 (3) on pages 362-363, DOI: 10.11646/zootaxa.5270.3.1, http://zenodo.org/record/7859886, {"references":["Saussure, H. de.

Roeseliana fedtschenkoi vasilii (Götz, 1969) Ĝtz, 1969. Mitt. Zool. Mus. Berlin, 45: 157 (Metrioptera fedtschenkoi vasilii); type locality and depository: Romania, Negresti, Moldau (SMTD, Dresden). Remarks. Ĝtz (1969) described this taxon from Romania as subspecies of R. fedtschenkoi, and considered it related to pylnovi, ambitiosa, minor and azami. Examination of the drawings of the titillators and the female subgenital plate of this taxon by Ĝtz (1969) shows that it is undoubtedly related to R. roeselii, but the female subgenital plate is similar to that of R. ambitiosa.

R. bispina was described by Bolívar (1899) as Platycleis roeseli var. bispina, characterized by stout head and differences in the subgenital plate of the female, which has a broad concavity. Zeuner (1941) raised the taxon to species level within Roeseliana. This was followed by Harz (1969) and Massa & Fontana (2011). Heller (1988) considered it as synonymous with R. roeselii and Ünal (1999, 2006, 2018) listed it as Metrioptera (Roeseliana) bispina, recording some new localities from north Turkey. Morphological characters (see also Table 2 and 4) allow to separate it from other eastern (like R. fedtshenkoi, R. pylnovi) and western taxa (like R. brunneri, R. azami minor and R. azami). Male titillators are little curved, slender and nearly unarmed, with only few small apical spines (Fig. 5n). Distribution.

However, R. roeselii occurs with holopterous males and females with a variable frequency, mainly in the north of its distribution; e.g., Szanyi et al. (2014) found a high frequency (≤ 53%) of holopterous individuals of R. roeselii in some meadows surrounded by forests of Hungary. R. roeselii is the most easily diagnosable species from a morphological point of view. It is the only species with titillators without arched tips with small apical spines and a narrow male supragenital plate (Figs. 5i–5j, 6b); in addition, the female subgenital plate is very deeply incised with two sharp apices (Fig. 8b; see also Ĝtz 1969). Male cerci and female subgenital plate are more similar to those of R. pylnovi than to those of south European taxa. In particular the shape of cerci shows a long apically pointed part and an inner backwards and pointed spine (Fig. 6b). The south European taxa of Roeseliana differ clearly from R. roeselii. According to Heller (1988), R. fedtschenkoi is synonymous with R. roeselii. See also R. fedtschenkoi. However, according to Heller et al. (1998) while the South European forms formerly included in Metrioptera fedtschenkoi belong to R. roeselii, this may be not true for all of the South East European and especially the Caucasian and central Asian forms. However, most authors agree with the validity of the two taxa R. fedtschenkoi and R. roeselii and consider both polytypic species. We were able to examine only the photos of the syntype of R. fedtschenkoi, and we found that the latter is different from R. roeselii. However, authors who have cited R. fedtschenkoi really examined specimens collected in countries different from the typical area of the species (Uzbekistan-Turkmenistan) and this may be the reason of some misinterpretation. For characters of R. roeselii see also Tables 2 and 3. Distribution. Wide areas of the Palaearctic region (Galvagni 2001); it has been introduced in Canada, Montreal and Ville St. Laurent in 1950; since then its range has increased in Ontario and Quebec, and into the United States as far as Illinois (Vickery et al. 1975, Capinera et al. 2004), where now it is rather frequent. It also has spread in North Europe; according to Kaňuch et al. (2013), due to the limited ability of R. roeselii to cross geographical barriers through active dispersal, it is very much probable that transport of eggs potentially occurred with agricultural products, and consequently at least some of the isolated populations originated from human-mediated introductions rather than natural dispersal. It is present from lowland to high elevations., Published as part of Massa, Bruno, Tagliavia, Marcello, Buzzetti, Filippo Maria, Fontana, Paolo, Carotti, Giovanni, Bardiani, Marco, Leandri, Fausto, Scherini, Roberto & Verde, Gabriella Lo, 2023, A taxonomic revision of the Palaearctic genus Roeseliana (Orthoptera: Tettigoniidae: Tettigoniinae: Platycleidini): a case of ongoing Mediterranean speciation, pp. 351-400 in Zootaxa 5270 (3) on pages 358-360, DOI: 10.11646/zootaxa.5270.3.1, http://zenodo.org/record/7859886, {"references":["Hagenbach, J.

Roeseliana n. sp. Lemonnier-Darcemont & Darcemont, in press. Figs. 22d, 23d Lemonnier-Darcemont & Darcemont, in press. Zoosystema; type locality and depository: Mazarakia, Epirus, Greece (MNHN, Paris). Remarks. The description of this species has been proposed when we finished our revision and we were not able to examine specimens; however, thanks to the courtesy of Michèle Lemonnier-Darcemont it was possible to examine some photographs and to provide biometrics. Measurements. Male. Body length: 19.5; pronotum: 6.5; tegmina: 9.5; hind femur: 17.5. Female. Body length: 24.5; pronotum: 6.5; tegmina: 7.5; hind femur: 21; ovipositor: 8.5. Male differs from Roeseliana oporina by the shape of cerci and of titillators, from R. bispina by the width of the base of the apical tooth of the cerci, from R. ambitiosa and R. azami by the shape of titillators and the arrangement of their spines, from R. brunneri by the shape of the last tergite. By their last tergite largely indented with narrow and pointed lobes at their extremity, they are however close to R. azami, to R. oporina and to R. ambitiosa. The internal tooth of the male cerci is short and placed at ¾ of the cerci, it is barely wider at its base than at the apex as R. ambitiosa, R. brunneri, R. oporina and R. azami. The shape of titillators is similar to that R. bispina, but with a different number and arrangement of spines. The shape of the female subgenital plate is intermediate between that of R. oporina and R. azami but with a much shallower incision and a less pronounced central keel (Lemonnier-Darcemont & Darcemont in press).

Roeseliana pylnovi (Uvarov, 1924) Figs. 1e, 1f, 3h, 6d, 8a, 10 Uvarov 1924. Trans. R. Entomol. Soc. London, 71(3–4): 534 (Metrioptera pylnovi); type locality and depository: Caucasus (UMO, Oxford). Material examined. Armenia, Tavush, Dilijan 6.VII.2005, M. Kalashian (5♁, 6♀) (BMPC); Georgia, Caucasus, Bakuriany 5–10.IX.1912, E. Konig (1♁, 1♀ paratypes) (NHM) (photographed by R.

Described in the genus Metrioptera by Uvarov (1924), it was transferred to the genus Roeseliana by Zeuner (1941). Following Tarbinsky (1932) it is synonymous with R. fedtschenkoi, but Zeuner (1941) listed it as valid species. Ramme (1951) considered R. pylnovi and R. fedtschenkoi different taxa, with different shape of wings. Ĝtz (1969) pointed out that the subgenital plate of female is more incised than that of R. fedtschenkoi, but he did not list specimens of the latter species. It seems that R. pylnovi is much related to R. fedtschenkoi and R. roeselii. However, titillators are different from those of R. roeselii (Fig. 6). Instead, the supra-anal plate and cerci of the male are a slightly similar to those of R. roeselii (Fig. 6d), however, differences may be detected with the female subgenital plate, which in R. roeselii is laterally more rounded (Figs. 8a and 8b).
