Diagnosis: Male with epandrium and surstyli distinctly bulb-shaped (posterior view). ( Fig. 7B ). Lateral surstylus shorter than epandrium; apex of posterior lobe of surstylus pointed, as long as anterior lobe. Proctiger quadrate and smaller than epandrium ( Fig. 4N ). Medial surstylus longer than lateral surstylus tapering towards apex with a pair of thick prensisetae ( Fig. 7B ). Phallus 2.3 to 2.5 mm long excluding glans (0.425 mm); 0.75 of glans sclerotised with patterned (hexagonal) praeputium; subapical lobe and basal lobe present ( Fig. 10L ). Female with brown oviscape (1.7 mm); elongate eversible membrane (4.03 mm), spiclues on distal end of eversible membrane with 5̄6 projections, tapering laterally ( Fig. 12I ); aculeus 2.4 mm long, with acute apex and three pairs of preapical setae ( Fig. 14 I ). Two brown, convoluted mulberry shaped spermathecae ( Fig. 15 M ).
