Type material examined
INDIA • 2 syntypes (Fig. 69A–E); head of Lanier River NE of Munipur; Godwin-Austen coll.; NHMUK 1903.7.1.2485.
Type locality
“Hills at head of the Lanier River, Naga Hills, ca. 5–6,000 feet ”.
Remarks
An easily recognisable species based on the three R3 swellings.
Differential diagnosis
Due to the complicated R3 swelling, this species is similar to some species of the Dicharax species group 7, but differs from most of those species by the more depressed shell, the rounded aperture, and the R3 swelling separated into 3 parts. See also under D. umashaankeri sp. nov.
