Holotype.

Australia • juv. ♂; Western Australia, Sharks Bay [Shark Bay] Inner Bar, auf dem Rücken der Bank [Inner Bar, backside of the bank], Hamburger südwest-australische Forschungsreise 1905 exped., stat. 022; 6–9 m depth; 16 June 1905; J. Wilhelm Michaelsen leg.; grobkrniger Sand und Sand mit Planzen [coarse-grained sand and sand with vegetation]; ZMH -K-016044.

Remarks.

Băcescu (1992) reported a male holotype deposited at the ZMB (no collection number assigned), with the same data as ZMH -K-016044. The ZMB Collection does not include Zimmer’s material of Cumella gibba (pers. comm. Antje Schwiering and Kristina von Rintelen, ZMB). Zimmer’s (1914) original description did not explicitly designate a holotype; however, his description is based on a single juvenile male, which will then be the holotype fixed by monotypy (ICZN; Article 73, section 73.1. 2).

Diagnosis.

Carapace with two depressions, each followed by a bump respectively in the middorsal line (seen from lateral); pseudorostral lobes meeting in front of ocular lobe but not forming a pseudorostrum; antennal notch distinct, wide and shallow; subrostral tooth blunt and little protruding; ocular lobe large and broad, with 8 lenses. The species is characterized by the two bumps in the posterior part of the middorsal carapace line (after Zimmer 1914).

Distribution.

West Australia, 6–9 m depth.
