Konarus cheiris Bamber, 2006 , 7–12; figs 3–5.

Pseudoleptochelia bulbus Bamber, 2006 , 16–20 (males only); fig 9.

Material: One female, holotype ( MNHN.Ta895), one female, paratype ( MNHN.Ta896), one male, (previously paratype of Pseudoleptochelia bulbus ) ( MNHN.Ta901 [part]), sample LF3 ‘83’, Baie de Santal, Loyalty Islands, 20º07.27′S 167º07.34′E, 12 m depth on red algae. Two females, paratypes ( BMNH 2005.216 – 217 ) on Sargassum , one female, robust morph, paratype ( MNHN.Ta897), one male, (previously allotype of Pseudoleptochelia bulbus ) ( MNHN.Ta900), on Halimeda, Lagon, Ilot Maitre , New Caledonia, 22º19.41′S 166º20.89′E, 20 m depth 9/11/95; all coll. Ichiro Takeuchi.

Remarks. Re-examination of material in the light of the comments of Bird (2011) has revealed that:

• the ischium of each of pereopods 2 and 3 does appear to have only one seta, although the possibility of a second one having broken off cannot be discounted; the carpi of these pereopods may have a very small rounded distal spine, but it could not be resolved clearly at a magnification of x 640;

• the dactylus of pereopod 1 has a long proximal seta (misinterpreted as being distal on the propodus in Bamber, 2006);

• the propodi of pereopods 4 and 5 do have three dorsodistal setae, as in the original description, rather than spines as in Parakonarus ;

• the carpi of the posterior pereopods have three, not four, distal molariform spines (as shown for K. straddi in Fig. 5C, D ), one inner, one outer and one ventral (the original description interpreted two ventral spines); this configuration also accords with the findings in Parakonarus .

The males generally resemble those of Parakonarus species , although they are without any ventral apophysis on the cheliped carpus ( Fig. 2C ), and without distal setules on the dactyli of the posterior pereopods.
