AFFINITIES. Jordanius maysaraensis gen. et sp. n. shows some morphological similarities with J. granulomanus comb. n. in the presence of large, rounded, somewhat pointed granules on the dorsal surface of chela manus; also in having a remarkably elongated chela manus. The new species can be distinguished from J. granulomanus comb. n. by:

a) having less dense and relatively smaller granulation on the external surface of chela manus ( Figs. 75–78 View Figures 75–78 ).

b) higher pectinal teeth number; 11–13 (average 12.0) in males (26 combs, n=13), 10–12 (average 10.9) in females (24 combs, n=12) in J. maysaraensis gen. et sp. n.; whereas it is 9–12 with average 10.7 in males (18 combs, n=9), 8–11 with average 9.9 in females (44 combs, n=22) in J. granulomanus comb. n.

c) general coloration of J. maysaraensis sp. n. is olive yellow ( Fig. 5 View Figures 3–8 ), whereas J. granulomanus comb. n. has generally reddish-brown coloration ( Fig. 6 View Figures 3–8 ).
