Diagnosis: Male with epandrium and surstyli distinctly bulb-shaped (posterior view) ( Fig. 6K ). Lateral surstylus longer than epandrium; posterior lobe of surstylus 10 times longer than anterior lobe ( Fig. 4G ). Medial surstylus as long as lateral surstylus. Proctiger triangular and smaller than epandrium. Phallus 2.3 mm long excluding glans (0.35 mm); glans sclerotised with well developed patterned praeputium (triangular and circular pattern), trumpet-shaped subapical lobe and short basal lobe; vesica sclerotised slightly to form hook-like structure ( Fig. 10E ).
