Subhimalus Ghauri, 1971

Subhimalus Ghauri, 1971: 113

Type species: Subhimalus melanus Ghauri,1971

Brownish-black species, often with light veins on forewings. Head slightly wider than greatest width of pronotum, anterior margin slightly produced medially; posterior margin almost parallel to anterior margin. Vertex triangular, each side near fore margin with oblique streak; median length longer than width between eyes, coronal suture distinct. Eyes greyish brown, fairly long and oblique; ocelli pale yellow, located on the lateral margin of vertex, separated from adjacent eye by approximately their own diameter. Face with dark, often confluent, transverse streaks. Frontoclypeus narrow, longer than width between eyes, anteclypeus slightly narrowed apically. Antennae arising near lower corner of eye. Scutellum triangular, with large black spot at base, its length slightly shorter than length of pronotum, with transverse suture curved and depressed. Forewings with 4 apical cells and 3 subapical cells, subapical cells confused among reticulate veins, clavus irregularly reticulated with many extra veins, appendix narrow. Male genitalia. Pygophore slightly longer than high, with two groups of macrosetae, one basolateral, other posterodorsal. Valve short, subtriangular. Subgenital plate short and broad, with macrosetae and thin hairlike setae arranged in irregular sublateral band extended to apex. Aedeagus with broad base, with well-developed dorsal apodeme, moderate-sized shaft, gonopore apical on ventral margin. Connective, loop-shaped with arms fused apically, stem absent. Style, base broad and short, apical process long with serrate at apex, internal process elongate.

Remarks. Subhimalus may be distinguished from other Paralimnini by the following combination of features: forewing subapical cells and clavus irregularly reticulated with many extra veins; pygophore with basolateral and posterodorsal groups of macrosetae; style with external process elongate.

Distribution. Oriental Region.
