Material examined. Jordan, Aqaba, Murjan , 10–14 m, holotype, paratypes, other specimens, NHMW 15759–16777 View Materials (5.0– 6.2 mm) .

Diagnosis. Major cheliped merus 1.8 times as long as wide, lower margin with distally directed proximal spine; propodus palm 1.8 times as long as carpus, 1.2 times as long as wide, with oblique gape (narrower than base of each finger), without tooth; fixed finger half as long as palm, with subdistal tooth on cutting edge; dactylus as long as fixed finger. Uropod endopod oval, 1.2 times as long as greatest width, upper face with at least 2 short spiniform setae; exopod wider than length of anterior margin. Telson 1.1 times as long as wide, tapering to about 0.9 greatest width.

Distribution. Western and Central Indo-Pacific ( Jordan [type locality: Aqaba], Philippines, Indonesia); 10– 14 m.

Remarks. Dworschak (2003) illustrated the small ‘branchiostegal sclerite’ below the anterior of the linea thalassinica but did not note that the suture separating it from the branchiostegite is incomplete (fig. 2a, b). Pleomere 6 has an oblique groove posteriorly on the ventrolateral margin (fig. 2c–e) as do all species of Aqaballianassa .

Sakai (2011) placed the species in Cheramus without explanation.
