Capnogryllacris (C.) elongata ( Fritze, 1908) View in CoL

Figs. 47F View FIGURE 47 , 48K View FIGURE 48 , 50 View FIGURE 50 F–G

Holotype (male): Indo-Malaysia: Borneo—Genève ( MHNG), seen but not studied in detail.

Material examined. Malaysia: Pahang, Taman Negara , forest trails, 19–22.vii.1984, leg. S. Ingrisch— 1 male (Bonn ZFMK) .

Additional Description. Medium sized to large species. Head: Face ovoid; forehead nearly smooth; fastigium verticis wider than scapus; ocelli distinct; fastigium frontis separated from fastigium verticis by a very fine suture; subocular furrows very shallow ( Fig. 48K View FIGURE 48 ). Abdominal tergites two and three without stridulatory pegs.

Wings surpassing middle of stretched hind tibiae ( Fig. 47F View FIGURE 47 ). Tegmen: Radius forked near tip; media anterior at very base free, then it closely approaches or sub-fuses for about 5 mm with radius, after both veins separated again media receives a short oblique connection vein from radius (probably RS), in apical third of tegmen MA separates from the fused MA+RS vein as an oblique posterior branch while RS terminates into three posterior branches; cubitus anterior at base single-branched and distinctly thickened, it divides at end of basal third, the first branch in a curvature and then divides into MP and CuA1; CuA2 remains single branched. Cubitus posterior undivided, free throughout; with 4 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 ventral spines and one pair of smaller ventral spurs; hind femur with about 6–7 external and about 12–14 internal spines on ventral margins getting distinctly larger towards end; hind tibia with spaced spines on both dorsal margins, ventral margins with one pre-apical spine; with 3 apical spurs on both sides.

Coloration. General color medium brown with indistinct ornament; rim of pronotum red brown. Face yellowish brown; antennal scrobae, a wide vertical band below compound eyes, margins of clypeus and labrum and maxillary palpi dark brown. Tegmen semi-transparent yellowish, towards base darker; veins medium to dark brown; hind wing dark red brown, towards hind margin lighter and cells with yellowish spot in middle; main veins black to brown; cross veins medium brown to yellowish.

Male. Eighth abdominal tergite with dorsal area prolonged, not laterally. Ninth abdominal tergite with a strong medial furrow, globular on both sides; semi-globes at ventro-internal angle compressed and prolonged into a large compressed triangular process pointing about mediad; process at base yellowish, afterwards dark brown with black margin ( Figs. 50 View FIGURE 50 F–G). Epiproct small triangular. Subgenital plate wider than long with a large triangular excision from base, lateral margins convex and converging, apical margin wide roundly excised, with a shallow furrow in midline between apical and basal excisions; cerci little upcurved, longer than subgenital plate, inserted at wide trunks that occupy all of the non-excised apical margin. Phallus membranous.

Measurements (1 male).—body w/wings: 51; body w/o wings: 29; pronotum: 6.5; tegmen: 42; tegmen width: 12; hind femur: 18; antenna: 85 mm.

Discussion. Habitus and wing venation agree with the type of Capnogryllacris (C.) elongata ( Fritze, 1908) , except that MA is fused with R in subbasal area instead of only leaning on R but not fused as in the type; basic color of hind wings is dark reddish brown instead of more yellowish brown in the type. Also in the holotype there is a short oblique connection branch from R to MA (fusion of RS with M) although it is missing in the drawing that came with the original description by Fritze in Carl (1908). The shape of the male ninth abdominal tergite and its processes agree with the descriptions in Fritze in Carl (1908) and Griffini (1911d).
