New taxa and records of Gryllacrididae (Orthoptera, Stenopelmatoidea) from South East Asia and New Guinea with a key to the genera Author Ingrisch, Sigfrid text Zootaxa 2018 2018-11-05 4510 1 1 278 journal article 27991 10.11646/zootaxa.4510.1.1 f3128a32-5f0b-413e-a755-c859bdd7cac4 1175-5326 10072806 EAA35595-0972-4CF8-A128-16267A59112B Gryllacris (Gryllacris) peracca Karny, 1923 Figs. 16 G–H, 17C Gryllacris kledangensis Karny, 1923 syn. nov. Gryllacris lombokiana Karny, 1926a syn. nov. (synonymised by Karny 1937 under G. kledangensis ) Material examined. Malaysia : Perak , Gunung Kledang , elev. 807 m ( 4°35'5.25''N , 101°1'19.4''E ), 1–30.xi.1901 — 1 male ( holotype ) (London BMNH ) ; Perak , Gunung Kledang , elev. 807 m ( 4°35'5.25''N , 101°1'19.4''E ), 1 female ( holotype of G. kledangensis ) (London BMNH ) ; unknown locality (Lombok in lit. in error, probably Gunung Kledang see Karny 1937 )— 1 female ( holotype of G. lombokiana ) (London BMNH ) . Discussion. The synonymy of G. lombokiana with G. kledangensis was already established by Karny 1937 . The description of the younger taxon was due to locality "mixup". G. kledangensis ( 1 female ) and G. peracca ( 1 male ) were both collected at the same locality, there are no morphological differences between both types except for sex specific characters, the slightly smaller size of the male falls within a supposed variation range of a species; there are also no differences in coloration (although mentioned in Karny 1923 ): the pronotum shows an extremely faint dark pattern in both specimens, and also the widths and extensions of the dark bands on the hind wings are identical; also the venation of the tegmina in both specimens fully agrees (but somewhat deviates in the female type of G. lombokiana , in which the two branches of CuA separate only in the apical third of tegmen while in both other specimens before mid-length. I thus have no doubt that both type specimens belong to the same species. The name G. peracca is chosen here as the dominant name as the type is a male, which in this genus shows better diagnostic characters than females, which may ease differentiation against other similar species. Description. Medium sized to large species. Head: Face ovoid; forehead nearly smooth with shallow transverse riffles; fastigium verticis hardly wider than scapus; ocelli visible; fastigium frontis separated from fastigium verticis by a transverse suture; subocular furrows present. Tegmen: Radius with two branches, both forked near tip; media anterior fused in basal area with radius, afterwards single branched; media posterior absent; cubitus anterior forks between basal third and mid-length into two veins, CuA1 and CuA2; cubitus posterior undivided, free throughout; with 4 anal veins. Legs: Fore coxa with a long spine at fore margin. Coloration: General color uniformly brownish. Face rather uniformly reddish brown with yellowish ocelli. Tegmen semi-transparent yellow with yellowish brown veins, veinlets of lighter color; hind wing semi-transparent; main veins brown; cross-veins blackish and bordered on both sides by dark bands. Male. Ninth abdominal tergite behind mid-length nearly rectangularly bent down and suddenly narrowed to posterior area, just before constriction with a small obtuse tubercle at both sides; posterior area with faintly converging, nearly subparallel margins; apical margin subtruncate. Apex of subgenital plate convex, very faintly excised in middle. Female. Seventh abdominal sternite wider than long, of normal shape. Subgenital plate with widened base rather short; central area with subparallel lateral margins, very faintly converging; apical area bi-triangular with apex excised in between; surface little modified, faintly sunk-in in middle, at base swollen, the apical triangles with rather weak oval swellings; behind basal swelling with a very small, linear sclerite ( Figs. 16 G–H). (in the type of G. kledangensis one of the apical triangles is broken). Ovipositor long, moderately curved, with faintly approaching margins; tip with a slight pre-apical expansion ( Fig. 17C ). Measurements partly after Karny (1923) ( 1 male , 2 females ).—body w/wings: male 38, female 45; body w/o wings: male 29, female 31–38; pronotum: male 6.5, female 7–8; tegmen: male 29, female 32; tegmen width: male 10, female 11.0–11.5; hind femur: male 18.5, female 20.5–21.5; ovipositor: female 22.5–25.0 mm.
