Figs 1 , 2

Inodesmus jamaicensis Cook 1896: 25 ; Attems 1898: 266; Loomis 1969: 144; Jeekel 1971: 310; Hoffman 1999: 483.

Diagnosis: Males possess a head + 19 rings, while females have a head + 20 rings. Adult males differ from other species of Inodesmus by their unmodified legs and gonopod structure. The telopodite ( Figs 1A–D ) exhibits the following features: pp slightly curved posteriorly, apical tab at is short, pointy, and bent posteriorly; dp directed laterobasally; mab divided into two wide triangular lobes. meb with two branches curving behind mab.
