Eupholidoptera singularis Ünal

sp. nov.

Eupholidoptera singularis Ünal  , sp. nov.

( Figs. 300–311 View Figure , 339–348 View Figure )

Description. Male (holotype): Fastigium of vertex as wide as width of eye. Antennal scapus 1.8 times narrower than fastigium of vertex and width of eye; 1.3 times wider than frontal groove. Pronotum ( Figs. 300–303 View Figure , 339 View Figure ) 2.2 times longer than high; with sooth surface, prozona cylindrical, metazona slightly flattened; anterior margin very slightly concave, posterior margin convex but with a weak concavity in the middle; metazona extended posteriorly, reaching beyond half of 1 st abdominal  tergite, never extending beyond end of 1 st tergite  in paratypes; shoulder incision distinct as a weak concavity. Tegmina ( Figs. 30 View Figure 0–303, 339) almost concealed, slightly protruded under pronotum, reaching to 1/3 of 2nd abdominal tergite, not reaching beyond the end of 2nd tergite in paratypes. Femora unarmed. Hind femur ( Figs. 300–301 View Figure , 339 View Figure ) very short, only 4.1 times longer than wide, reaching to end of abdomen, slightly longer in some males; longer proximal part wide, narrowed distal part very short. Last abdominal tergite ( Figs. 304 View Figure , 341–342 View Figure ) strongly narrowing to apex, 1.75 times wider than long; posterior margin strongly downcurved (almost under right angle) with 2 short, spine-like lobes and with a wide, shallow, broadly rounded incision. Cerci ( Figs. 304 View Figure , 343 View Figure ) unique in the genus, short, straight with a large inner tooth placed in distal part of cercus; inner tooth pointed with slightly upcurved spine; apical narrowing part slightly longer than inner tooth. Subgenital plate ( Figs. 305–306 View Figure , 344–345 View Figure ) divided into left and right parts along its length, longer than wide; posterior lobes very long and narrow, converging each other apically, with a large strongly upcurved apical spine; styli large as long as the apical spine. Titillator ( Figs. 307 View Figure , 346–347 View Figure ) slender, basal arms almost V-shaped, reaching to half of unfused part of apical arms; apical arms fused in basal 2/3, slightly widened; apical 1/3 part unfused, like 2 long spines, slightly curved forewards and touching each other at apex.

Female: Fastigium of vertex almost as wide as width of eye. Antennal scapus 1.9 times narrower than fastigium of vertex; as wide as frontal groove; 1.8 times narrower than width of eye. Pronotum ( Figs. 308–310 View Figure , 340 View Figure ) as in male, but reaching 1/3 of 1 st abdominal  tergite, 1.5 times longer than high and shoulder incision slightly more distinct. Tegmina ( Figs. 308–310 View Figure , 340 View Figure ) fully concealed under pronotum, reaching to end of metanotum, in some females slightly longer; contiguous at dorsum. Legs ( Figs. 308 View Figure , 340 View Figure ) as in male. Hind femur slightly surpassing the end of abdomen. Last abdominal tergite short and wide, slightly extended posteriorly and strongly narrowed in the middle, posterior margin slightly concave. Cercus simple, spine-like, longer than last tergite. Subgenital plate ( Figs. 311 View Figure , 348 View Figure ) short (2.6 mm), slightly longer than wide, without median carina; apical lobes triangular but hind corner very narrowly rounded, with a deep V-shaped incision reaching slightly less than 1/3 of the length of plate, in Taraşcı population as wide as long and posterior incision smaller. Ovipositor ( Figs. 308 View Figure , 340 View Figure ) weakly longer than hind femur, in paratypes slightly shorter; slightly upcurved along its length; narrowed in the middle part and weakly widened in distal part; apex sharply and regularly pointed.

Color. Body almost unicolor yellowish cream with several typical black, yellow orange parts. Head, pronotum (except metazona), legs including hind femora without any dark spots or stripes. The extended part of metazona orange in dorsal view. Male tegmina black except the narrow creamish part of costal margin. Dorsal surface of 1 st abdominal  tergite in both sexes black. Apical half of abdomen yellowish, basal half slightly brownish in male. Male last tergite black. Ovipositor with short black stripe on dorsal surface basally; apical part slightly darkened.

Diagnosis. This new species is easily recognizable by the unique male cerci with a large inner tooth in distal part. Male subgenital plate somewhat similar to Eupholidoptera unimacula Karabağ, 1956  and Eupholidoptera tucherti Harz, 1988  , male last tergite near to Eupholidoptera prasina (Brunner von Wattenwyl, 1882)  and Eupholidoptera karabagi Salman, 1983  and titillator somewhat similar to Eupholidoptera tasheliensis Çıplak, 1999  . But the remaining characters are different from these species. Female subgenital plate smaller but similar to Eupholidoptera annulipes (Brunner von Wattenwyl,1882)  . But this similarity is superficial and all the other characters are very different. Moreover both species are in different species groups. Although this species have male cerci with inner tooth it is clearly in E. prasina  species group by the small size, short hind femur, unicolor body and pronotum.

Material examined. TURKEY: Antalya, Gündoğmuş, Geyik Dağları , Susambeli , 2300 m, 20.9.2017, 4 males (including holotype)  , 3 females, plus 2 males, 5 females in alcohol; Antalya, Gündoğmuş, Geyik Dağları, Namaras yaylası-Susambeli, 2200–2330 m, 14.7.2017, 3 males nymph, 1 female nymph (in alcohol)  ; Antalya, Gündoğmuş, Susambeli , southern slopes, 2230 m, 14.7.2017, 1 male nymph (in alcohol)  ; Konya, Seydişehir, Taraşcı, Rezebeli , 1960–1990 m, 2.9.2015, 1 male, 2 females, plus 1 female in alcohol, 3.9.2015, 1 male, 1 female, plus 1 female in alcohol, 1850–2180 m, 17.7.2017, 1 female, plus 3 males nymph, 5 females nymphs in alcohol (all leg. M. Ünal) (AİBÜEM). 

Measurements (mm). Holotype: body 20; pronotum 7.2; hind femur 13.3. Paratypes: body: male 20.2–23.8, female 19.5–22.2; pronotum: male 6.1–7.6, female 6.3–7.6; hind femur: male 12.3–14.7, female 13.7–15.9; ovipositor: 13.3–15.6.

Etymology. The species name “ singularis  ” in Latin means unique, unmatched. The new species has unusual male cerci in the genus.

Remarks. The specimens of Rezebeli population have larger size. This new species was found with E. tasheliensis in Susambeli Pass  and with E. anatolica in Rezebeli Pass  as congeneric partners.
