Remarks
Diogenes rectimanus
is referred to the
D. edwardsii
species group (
Asakura and Tachikawa 2010
), and is characterized by the following features: left chela with scattered stiff setae on outer surface, armed with sharp spines, forming longitudinal rows proximal to base of dactylus and on midline; carpi of second and third pereopods each with row of spinules on dorsal surface; propodi of third pereopod unarmed on dorsal margins; antennal peduncles clearly overreaching distal corneal margins; telson with spines continued onto lateral margins at least on left posterior lobe (
McLaughlin and Clark 1997
;
McLaughlin 2002b
;
McLaughlin et al. 2007
). The present specimens from Chinese waters agree well with
D. rectimanus
in every diagnostic aspect, fully confirming the occurrence of this species in Chinese waters.
