Gnathia camuripenis Tanaka, 2004

Ganathia camuripenis Tanaka, 2004: 51 [type locality: Urasoko Bay, Ishigakijima Island, Japan, 24°27ʹN, 124°13ʹE]. — Ota et al. 2007: 1266. — Ota & Hirose 2009a: 57; 2009b: 49.— Ota 2010: 3; 2011: 49.

Material examined. One male 3.15 mm in total length (RUMF-ZC-1434), from sand and mud sediment, Stn. Dredge 68 (silver dredge), 26°19.095ʹN, 126°49.008ʹE – 26°18.898ʹN, 126°48.969ʹE, 10.7–17.1 m depth, off Kumejima Island, the Ryukyu Archipelago, southwestern Japan, 18 November 2009.

Remarks. Gnathia camuripenis was originally recorded from a coral rubble trap that was placed in 0.5–1.0 m depth at Ishigakijima Island, south Ryukyus. Both adults and larvae were described in detail. The adult male of this species is easily distinguished from the other Gnathia species by remarkably large penes fused into a single crooked blade and mandible with 2 inner lobes ( Tanaka 2004).
