Diagnosis

Brachypterous, pale testaceous to light brown, with sparse dark brown speckling. Male pygofer roundly lobate, with oblique groove dividing basal section from apical lobate section which bears subapical biseriate row of macrosetae decreasing in length from dorsal to ventral. Ventral margin of lobe emarginate forming two ventral prominences. Subgenital plates forming quadrate, transverse plate. Parameres with apical section finely rugose, well sclerotised, short, broad and shallowly concave apically with outer lobe narrower than inner which is little more than angulate corner. Basal section transverse, narrowing towards articulation with connective. Aedeagus stout, parallel sided, curved anterodorsally, bifurcate apically on anterodorsal side of apical gonopore. Female: Pregenital sternite with hind margin sinuately emarginate, deeply and triangularly excavated medially. Length: Female 3.80–3.82 mm (males are comparable in size but length is difficult to estimate once the abdomens were removed) (Fletcher & Zahniser 2008).
