Abstract Allathelges pakistanensis, new genus, new species, is described as a parasite of Paguristes perspicax near Karachi, Pakistan. Allothelges is distinguished from other athelgine genera by the following characters: female, head no longer than broad, oostegite I folded and extending well beyond head, all pereiopods evenly spaced, no posterolateral extension of oostegite 5, 5 pairs of biramous pleopods, no uropods; male, head separated from pereion, pleonal margins not indicating fused pleomeres. Allathelges is most similar to Athelges from which it differs by having 5, not 4, pairs of biramous pleopods in the female. The other 4 known species of the Athelginae in the Indian Ocean are reviewed. Anathelges mossambica and Athelges caudalis are so poorly known that it is uncertain whether their generic placements are correct: Athelges aegyptius was well described and correctly placed; and Athelges nentenuicaudis is reassigned to the genus Parathelges.
