Type material examined

INDIA • holotype (single shell mentioned in the original description: Fig 63F–J); Darjeeling; Godwin-Austen coll.; NZSI M.8075 • several shells (Fig. 63A–E); Rissom Pk. (W. Bhutan); Godwin-Austen Coll.; NHMUK 1903.07.01.2552 .

Type locality

“Darjeeling”.

Differential diagnosis

Dicharax nongtungensis is smaller, has a thicker peristome and a narrower umbilicus. Dicharax politus has a more depressed shell and a more strongly inflated R3 swelling. See also under D. dalingensis, D. ganeshaiahi sp. nov., and D. nattoungensis .

Remarks

This species was described based on a strongly corroded shell (Godwin-Austen 1874). Later, Godwin-Austen (1914) provided a more complete description and drawings based on multiple additional specimens. We received photos of the holotype (Fig. 63F–J) from the Zoological Survey of India, and could confirm that the figured shell (Fig. 63A–E) is conspecific with the holotype.
