Victoriasquilla poorei, a new genus and species of mantis shrimp from southern Australia, and a range extension for Hadrosquilla edgari Ahyong, 2001 (Crustacea: Stomatopoda: Nannosquillidae)

Abstract

Victoriasquilla poorei, a new genus and species of nannosquillid stomatopod from southern Australia is described. Victoriasquilla poorei appears to be most closely related to species of Austrosquilla, especially A. osculans (Hale, 1924), with which it shares a similar rostral plate, a similar complement of antennal papillae, similar raptorial claw armature, and telson and uropod structure. Victoriasquilla poorei also superficially resembles the eastern Atlantic Nannosquilloides occulta (Giesbrecht, 1910), but differs in numerous features including fusion of the ocular scales, the number of ventral papillae on the antennal protopod, size of the epipod of maxilliped 5, the armature of the basal segment of the pereopods and posterolateral margin of AS6, and the absence of a 'false eave' on the telson. New distributional records of Hadrosquilla edgari are also reported.
