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.
