Type locality.

"Mangut Valley, Jaintia Hills".

Material examined.

Mangat valley, Jiantia Hills, leg. Godwin-Austen, NHMUK 1903.7.1.2518 (8 syntypes).

Remarks.

Protoconch matte, R1 with regular, widely spaced, rather low ribs; no spiral striation observed; R2 very short, with ca. four ribs which are similar to the ones on R1 in terms of density and morphology.

This species was described as A. mangutensis by Godwin-Austen in 1914, and that name was later used as a valid taxon name ( Gude 1921; Ramakrishna et al. 2010). However, the name Alycaeus (Dioryx) granum var. major Godwin-Austen, 1893 for the same taxon was validly introduced, and is available. Thus, the species must be called Pincerna major (Godwin-Austen, 1893), and the name Alycaeus mangutensis Godwin-Austen, 1914 is a junior objective synonym.
