Joeropsis sp. 12

Material.

♀ (non-ovig. 3.2 mm), Hicks Reef, 14.44803°S, 145.4992°E, 21 February 2009, outer reef front, dead coral heads on reef edge, 5-7 m, LIZ09-16E, coll. NLB & MB-P (MTQ W31288).

Remarks.

The single specimen lacks both antenna. The dorsum is more setose than in other species and is covered in pale-brown chromatophores, these being more dense on the head forming a short (40% head length) band; the pseudorostrum is evenly rounded, the uropods have a prominent terminal spine and the pleotelson lateral margins each have 6 spines. There are no other similar species in the region; Joeropsis adusta sp. n. is smaller, less densely setose, and appears evenly dark brown; Joeropsis salvati Müller, 1989 is smaller still, and has a slightly truncate pseudorostrum.
