Alycaeus (Dicharax) obscurus - Gude 1921 : 263. Chamalycaeus (Dicharax) obscurus - Ramakrishna et al. 2010: 64. Type locality. "Cherra Poonje". Material examined. Cherra Poonje, leg. Godwin-Austen, NHMUK 1913.3.16.8 (1 syntype). Remarks. Protoconch slightly elevated, but no spiral lines visible; R1 also without spiral lines; R2 moderately long with relatively dense but spaced, sharp ribs. The slightly elevated protoconch and the morphology of the ribs is similar to that of Chamalycaeus , but they are closer to each other than usually occurs in that genus.
