A new genus and species of the ghost-shrimp family Callianideidae from the Caribbean coast of Panama (Decapoda: Axiidea)

A peculiar new species of ghost-shrimp from Bocas del Toro Archipelago on the Caribbean coast of Panama is assigned to the genus Trichocallia gen. nov. in the family Callianideidae. The holotype and presently the only known specimen of Trichocallia delicatula sp. nov. was collected with a suction pump on a silty-muddy bottom under a network of decomposing and partly overgrown mangrove roots. The new genus appears to be most closely related to Callianidea H. Milne Edwards, 1837, with two species in the Indo-West Pacific, and Paracallianidea Sakai, 1992, with two species, one in the western Atlantic and one in the eastern Pacific.
