Type material examined

INDIA • 3 syntypes; Shengorh Peak, Dafla Hills; Godwin-Austen coll.; NHMUK 1903.7.1.2498 .

Type locality

“Shengorh Peak” and “Tánir ridge at 4000 feet ”.

Differential diagnosis

Dicharax tangmaiensis is larger, and has a shorter distance between the R3 swelling and the peristome. See also under D. plectocheilus .

Remarks

The shell regions and the sculpture are similar to D. digitatus, but the undulation of the peristome started anterior to the R3 swelling. Moreover, the R3 swelling is situated at a greater distance from the peristome edge. Therefore, D. subdigitatus is a species in its own right, instead of a subspecies of D. daflaensis .
