Diagnosis. Major cheliped dactylus swollen, upper and lower margins dentate; fixed finger with 2 dentate cutting edges. Rostrum acute, simple. Cl. to 18.1 mm.

Distribution. Red Sea and Gulf of Aden, Western Indian Ocean ( Saudi Arabia, Madagascar [type locality]).

Remarks. Lenz and Richters (1881) illustrated the minor cheliped that, with its broad spinose dactylus, immediately distinguishes this species from other species of Lepidophthalmus , from all other callichirids and from members of related families. Sakai et al. (2014) synonymised L. socotrensis with Podocallichirus madagassus [sic]; the new material would seem to confirm this and any differences in the shapes of the uropod and telson are size-related. The species’ range is extended into the Red Sea.

The male pleopod 1 has a short second article with a distal triangular apex (fig. 3a); pleopod 2 has an appendix masculina bearing a small field of hooks, all that remains of the appendix interna (fig. 3b) – not as complicated as in Sakai (1999: fig. 10). Female pleopods are typical of the genus (fig. 3c, d)—the appendix interna on pleopod 2 is placed about two-thirds along the mesial margin of the endopod.
