Treatment

Alycaeus chennelli Godwin-Austen, 1886: 192-193, pl. 48, fig. 2.

Alycaeus chennelli and chennelli var. - Godwin-Austen 1914: 387.

Alycaeus (Dicharax) chennelli - Kobelt 1902: 366; Gude 1921: 240-241.

Chamalycaeus (Dicharax) chennelli - Ramakrishna et al. 2010: 57.

Type locality.

“Piknúi, Naga Hills"; "Lhota Naga Hills" ( chennelli var.).

Material examined.

Piknui, Naga Hills, leg. A. Chennell, NHMUK 1903.7.1.2612 (8 syntypes); Lhota Naga Hills, leg. Chennell, NHMUK 1903.7.1.2613 (10 shells = " chennelli var.").

Remarks.

Protoconch rather glossy, low, no spiral lines visible; R1 glossy, with widely spaced sharp ribs which are present only near the suture, and without spiral lines; R2 with curved ribs, typical to Dicharax .

The only stable character which distinguishes D. chennelli from D. diagonius is the presence of a lower apertural bay in the former, whilst it is absent in the latter.
