Type locality: Ceylon [ Sri Lanka] .

Type material (Holotype, female) in NHMUK, examined .

Description of male genitalia. Uncus tapered, apically rounded; gnathos arms thin, long, not fused; gnathos reduced; valve leaf-like costal edge uneven, abdominal edge almost smooth, apically acute; juxta saddle-like, with pair of leaf-like lateral processes; saccus semicircular, of medium size; phallus very big, thick, longer than valve, strongly curved on border between basal and medium thirds, vesica with robust cornutus which is about third of valve in length.

Description of female genitalia. Ovipositor very long, with transverse notching on lateral surfaces; anterior apophyses one third shorter than posterior apophyses; membranous portions of genitals absent on slide, probably due to the specimen being damaged by the collection pests.
