Type material examined

INDIA • holotype (single shell mentioned in the original description: Fig. 56A–G); Koliaghur nr Tezpur, Assam; NHMUK 1903.7.1.2682 .

Type locality

“Koliaghur or Koliahur, Nowgoug District, Assam ”.

Differential diagnosis

Similar to D. chennelli, D. damsangensis, D. diagonius and D. vitreus, which have similar R1 sculptures. Unfortunately, the holotype specimen is broken at its R3, making it difficult to examine some key characters. Nevertheless, D. nowgongensis has a rounded aperture and a relatively low-spired shell, which differs from most congeners of the same species group.
