Material examined: 5♂♂, 5♀♀, INDIA, West Bengal, Kalimpong , 8.xi.2016, Rakseh Pashi

Diagnosis: Male with epandrium and surstyli inverted U-shaped (posterior view) ( Fig. 7A ). Lateral surstylus much reduced than epandrium; apex of lateral surstylus not differentiated into anterior or posterior lobes. Proctiger quadrate and smaller than epandrium ( Fig. 4M ). Phallus elongate (6.17 mm long) excluding glans (0.5 mm); threefourth of glans sclerotised with fully patterned praeputium; subapical lobe and basal lobe present ( Fig. 10K ). Female with brown, bottle shaped oviscape (1.20 mm); elongate eversible membrane (3.35 mm) with spiclues on distal end conical ( Fig. 12H ); aculeus (3.28 mm) with acute apex ( Fig. 14H ). Two black, convoluted mulberry shaped spermathecae.
