C.L = length of carapace; G.W = width of same; G.L = length of genital segment; G.W = width of same. 
Proportion of genital segment and carapace is taken from the drawings given by the original authors unless otherwise indicated. 
Numerals shown in the rightmost column represent from the left to the right the number of spines on each of joints from basal 
to apical in due order. They denote, when put in parentheses, the spine borne on the outer border of joint, otherwise the terminal 
spines. Presence or absence of spine on the protopodite is indicated by 1 ) or 0) . 
’Kirtisinghe’s alalongae does not seem conspecific with Kroyer’s. 
-C. fulvipurpureus Shiino is a synonym of macarovi.
