Austin B. Williams and Robert B. Moffitt

Abstract. -Deepwater trapping in the Mariana Archipelago, western North Pacific Ocean, included incidental catches of a spider crab and a homoloid crab with novel characteristics. Bothromaia griflni, new genus and species, family Majidae, subfamily Inachinae, represented by a male and female, seems most closely related to the genus Pleistacantha Miers, containing several species distributed in Indo-Pacific waters. The new species resembles members of this genus with respect to presence of pseudorostral horns, and shape of eyestalks, basal antennal article, epistome, third maxilliped, male sternites and pleopod 1, but differs from them in shape of pseudorostral horns, carapace, male pleo- pod, and in proportions of the ambulatory legs. Descriptions, illustrations, and comparative discussion are presented. Notes on the homoloid crab, Poupinia hirsuta Guinot, include locality data, measurements, remarks on distribution, and discussion of features distinguishing the families of Homoloidea, including a key for their identification.
