Paradoxapseudes floppae Bird, 2015

Fig. 12D

Paradoxapseudes floppae: Bird (2015) : 370 –375, figs 1–5, 400, table 2; Bird (2019): 69, table 10.

Material examined. 99 specimens, AMS P.103183, SWP2017-135-2; 7 neuters, two preparatory (prep.). ♀♀, 3 ovigerous (ov.). ♀♀, AMS P.103259, SWP2017-137-2; 8 neuters, 4 prep. ♀♀, AIM MA168502, SWP2017-143 -2.

Distribution. Raoul Island and Macauley Island, 4– 18 m.

Remarks. These new records conform to those obtained previously (ibid: 371, 375), although the shallowest depth is now potentially 4 m (vs. 10 m). A particularly useful tabulation of seven external characters of the thenknown sixteen species of Paradoxapseudes was published by Tzeng & Hsueh (2014) as the Bird (2015) paper was in press. Another species, P. shimojiensis Kakui & Fujita, 2020 , has been recently described. Excluding the number of antennal flagellar segments that is fairly consistent in the genus (five segments in 13 species, of 17), P. floppae shares, at the most, only two characters with three species: P. botosaneanui ( Guţu, 2001) with five pereopod-1 superior plumose setae, and twelve pereopod-6 basis superior plumose setae; P. garthi ( Menzies, 1953) with six and two antennular flagellar segments, and five and 13 uropod exopod and endopod segments respectively; and P. heroae ( Sieg, 1986) with two cheliped carpus ventral apophyses, and four pereopod-1 propodus inferior spines. An as yet undescribed NZ species of Paradoxapseudes from the East Coast of the North Island does not appear to be conspecific with P. floppae (Bird & Webber unpublished data).
