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 Xanthogryllacris timoriensis (Karny, 1931) Figs. 28 A–G Material examined. Indonesia : Iles de la Sonde , Timor central Soe ( 9°51'49.79''S , 124°16'35.78''E ), ex coll. le Moult— 1 female , 1 male (Brussels RBINS ) . Diagnosis. The male is characterized by the pair of stout, pincers-like projections at apical margin of ninth abdominal tergite that are little curved before acute tip ( Figs. 28 C–E). That resembles the situation in X. ralum sp. nov. but the projections in X. timoriensis are only little curved and pointing apicad not mediad The female is characterized by the largely membranous seventh abdominal sternite that terminates into a medium long beam-like process with sclerotised, obtuse tip. The female subgenital plate is rather flat, membranous at base, with converging margins and distinct bilobate tip ( Fig. 28G ). The measurements of the specimens at hand are little larger than the values given by Karny (1931). The female is described here for the first time. Description. Small species. Head: Face ovoid; nearly smooth with scattered impressed dots and very fine transverse riffles; fastigium verticis little wider than scapus; ocelli distinct; fastigium frontis separated from fastigium verticis by a very fine suture; subocular furrows distinct ( Fig. 28B ). Abdominal tergites two and three with stridulatory pegs (1, 8; 8, 10; n = 1 male ). Wings little surpassing hind knees ( Fig. 28A ). Tegmen: Radius releases RS little before mid-length of tegmen; media anterior fused in about basal third with radius; media posterior absent; cubitus anterior forks into two veins before mid-length; cubitus posterior undivided, free throughout; with 4 anal veins.

Scales 10 mm. FIGURE 30. Genus Xanthogryllacris : A–C , X. punctipennis aurantiaca (Brunner, 1888) male lectotype; D–F , X. punctata sp. nov. holotype; G–H , X. inquinata (Karny, 1928) comb. nov. holotype; I–J , X. lineata sp. nov. holotype.—Male abdominal apex in ventral (A, E) and apical view (B, D, G), apical teeth of ninth abdominal tergite in higher magnification (C, F, H); female end of abdomen with seventh sternite, subgenital plate and base of ovipositor in ventral view conserved in alcohol (H) and after desiccation (I). FIGURE 31. Genus Xanthogryllacris : A–C , X. p. ralum sp. nov. male holotype (A–B) and female paratype (C); D–F , X. p. dempwolffi (Griffini, 1909) female holotype (D), female from New Britain (E–F); G–H , X. p. keyica (Karny, 1925) male; I–J , X. p. subrecta sp. nov. female holotype.—Male abdominal apex in apical (A, G) and ventral view (B, H), female seventh abdominal sternite and subgenital plate (C–E, I), female ovipositor (F, J). Legs: Fore coxa with a spine at fore margin; fore and mid femora unarmed; fore and mid tibiae with 4 pairs of comparatively short ventral spines and 1 pair of smaller ventral spurs. Coloration. General color uniformly light brown. Face uniformly brown, labrum darker; lateral ocelli and a large spot around medial ocellus light yellow. Tegmen yellowish semi-transparent; hind wing with dark spots in cells. Male. Ninth abdominal tergite semi-globular: prolonged and down-curved laterally and apically; just above ventro-apical margin with a pair of compressed projections pointing mediad and with subacute tips ( Figs. 28 C–E). Female. Seventh abdominal sternite with transverse riffles; apical area prolonged into a narrow and moderately long projection with obtuse tip, covering base of subgenital plate ( Fig. 28G ). Subgenital plate in basal area membranous with stiffened lateral margins; otherwise conical with bilobate tip. Ovipositor of medium length, moderately curved dorsad, in subbasal area more strongly curved; with lateral furrow ending before reaching apical widening; dorsal margin with a slight expansion before tip ( Fig. 28F ). Measurements ( 1 male , 1 female ).—body w/wings: male 29.5, female 29; body w/o wings: male 20.5, female 28; pronotum: male 4.8, female 5; tegmen: male 21.5, female 20; tegmen width: male 7; hind femur: female 15; ovipositor: female 16.5 mm .
