Diagnosis

Male. Macropterous form; structure typical. Vertex and face brown, lighter spots coalescing and forming small bands across face, clypeus and antennae darker brown; pro- and mesonotum light in middle, dark brown outside of lateral carinae; rest of thorax, coxae, femora and abdomen dark brown; tibiae and tarsi light brown, spur on hind tibiae dark brown on outer side. Tegmina hyaline, fuscous brown, lighter over basal half, dark over apical half, especially distad of clavus; a triangular, lighter mark at end of costal cell and a smaller spot at apex of each apical cell, a small dark spot at apex of claval margin, rest of claval margin white or yellowish white; veins closely studded with black granules; wings hyaline, veins dark. Pygophor slightly compressed laterally, ventral edge medially produced into a small plate which is bifid at apex; at each side of base of plate the pygophor is slightly depressed; anal segment with a long, thin, inwardly curved spine from each ventral corner, spines reaching across pygophor; genital styles small, basal portion spindle-shaped, slightly flattened, apex drawn to a point which is at right angles to basal portion. Length, 2.7 mm; tegmen 4.
Female. Macropterous form, similar to male. Brachypterous form: heavier in build than the male, especially the abdomen, also lighter in colour; tegmina reaching about one fourth from apex of abdomen, hyaline, veins with brown granules, margin of clavus whitish with dark mark at apex; wings rudimentary (Muir 1916).
