Anancistrogera bicornuta ( Karny, 1930a)

Figs. 35 A–C

Material examined. Indonesia: Sulawesi: Celebes, 1 female (type) (Wien NHMW) .

Description. Small but rather stout species. Head: Face ovoid; forehead surface nearly smooth with scattered impressed dots; fastigium verticis little wider than scapus; ocelli visible but little distinct; fastigium frontis not clearly separated from fastigium verticis; subocular furrows present but not strong ( Fig. 35C ). Wings about covering abdomen ( Fig. 35A ). Tegmen: Radius with two branches, both forked near tip; media anterior free from base; forked behind basal third into two veins: MA and MP; cubitus anterior and cubitus posterior both single branched, free throughout; with 3–4 anal veins.

Coloration. General color uniformly brown. Face uniformly brown. Tegmen semitransparent yellow; veins yellow, darker towards base; hind wing semitransparent with darker venation.

Male unknown.

Female. Seventh abdominal sternite wider than long, before tip with a small pit on stiffened surface. Subgenital plate apical margin with three recurved (= preparation artifact) triangular lobes, the lateral two larger than the central one. Base of ovipositor ventral valves with strongly stiffened margins. Ovipositor long, moderately upcurved throughout; tip acute ( Fig. 35B ).

Measurements from Karny (1930a) (1 female).—body w/o wings: 16; pronotum: 4.2; tegmen: 12.5; tegmen width: 5; hind femur: 11.5; ovipositor: 9.5 mm.

Discussion. The general habitus of this and other species of the genus Anancistrogera is nearly identical to that of species described under Aphanogryllacris .
