discussion
Remarks. The only other species in Mesolamprops that have five terminal setae on the telson are M. bispinosus and M. japonicus, but in M. abyssalis the terminal setae are nearly equal in the female, and in the male the central seta is the longest. However, in M. bispinosa and M. japonicus the outer most pair of terminal setae are the longest, and the inner pair are shorter than the central seta. In addition, the pseudorostrum is distinctly produced in M. abyssalis, while M. bispinosa and M. japonicus hasve no obvious anteriorly projecting pseudorostrum.
