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 Eugryllacris sulcata sp. nov. Figs. 5E, 5K , 8 E–F, 9J Material examined. East Malaysia : Sabah , Mt. Kinabalu, Poring, elev. 500–700 m ( 6°5'N , 116°33'E ), 1– 31.vii.1992 , leg. K. Riede— 1 female ( holotype ) (Bonn ZFMK). Diagnosis. E. sulcata can be recognized by the deeply furrowed face ( Fig. 5E ), but especially characteristic are the shapes of the female seventh abdominal sternite and the subgenital plate ( Figs. 8 E–F). The seventh sternite is rounded disc-shaped except for the truncate basal margin, flat and without apical projection; also the subgenital plate is flat with a rather long membranous base, afterwards triangular but with truncate apical margin. This situation resembles somewhat the condition in Philippine Eugryllacris species as E. inversa sp. nov. and E. maculipennis laticauda ( Karny, 1925a ) . Both species also have a triangular subgenital plate with truncate tip and the seventh sternite without a medial projection with apex simply rounded in E. sulcata instead of slightly bilobate in E. inversa . Description. Large species ( Fig. 5K ). Head: Face wide ovoid; fastigium verticis about twice as wide as scapus; ocelli visible, especially median ocellus, but not very striking; fastigium frontis separated from fastigium verticis by a very fine suture; a pair of very strong sub-antennal furrows, starting at internal angle of antennal scrobae, separates central area of face from lateral areas and fuse ventrally with clypeo-frontal suture; clypeo-frontal suture interrupted in middle; subocular furrows also very distinct; clypeus with a fine transverse furrow below about basal third ( Fig. 5E ). Abdominal tergites two and three with few minute stridulatory pegs. Wings reaching or little surpassing middle of stretched hind tibiae ( Fig. 5K ). Tegmen: Radius with two branches, both forked near tip; media anterior fused in basal area with radius; media posterior absent; cubitus anterior forks before mid-length into two veins, CuA1 and CuA2; cubitus posterior undivided, free throughout; with 5 anal veins. Legs: Fore coxa with a spine at fore margin; fore and mid femora unarmed; fore and mid tibiae with four pairs of large, on mid tibiae comparatively short, ventral spines and one pair of smaller ventral spurs; hind femur with 8– 10 external and 5 internal spines on ventral margins. Coloration. General color green when alive; vertex unicolored; disc of pronotum unicolored, hind margin hardly darker. Legs of general color. Face almost unicolored, probably green when alive; clypeo-frontal furrows black connected by a dark brown line. Tegmen semi-transparent with green veins; area behind radius faintly infumate in basal half to two thirds; hind wing semi-transparent with green or brown veins and veinlets; cells with large dark brown spots. Male unknown. Female. Seventh abdominal sternite with apical margin as whole prolonged to cover base of subgenital plate; roughly appearing as a round disc with truncate base ( Figs. 8 E–F). Subgenital plate in about about basal third membranous except for sclerotised margins; with strongly approaching lateral margins; apex subtruncate, faintly concave ( Fig. 8F ). Base of ovipositor with a small sclerite before base of ventral valves. Ovipositor of medium length, distinctly but not strongly curved dorsad, margins slightly and gradually narrowing towards tip; dorsal margin with a slight expansion before tip ( Fig. 9J ). Measurements ( 1 female ).—body w/wings: 53; body w/o wings: 40; pronotum: 8.5; tegmen: 40; tegmen width: 19; hind femur: 19; antenna: 125; ovipositor: 17 mm . Etymology. The new species is named for the deeply furrowed face; from Latin sulcus (furrow).
