Acanthanas pusillus, new genus, new speceis, a miniature alpheid shrimp with spiny eyes from the Philippines (Crustacea : Decapoda)

Acanthanas pusillus, new genus, new species, is described on the basis of three specimens collected from coral and coral rubble in Panglao, Philippines. The new genus appears to be most closely related to Athanas Leach, 1814, from which it may be separated by the stouter, bulky body; the more concealed eyes with two peculiar acute projections; the presence of a subacute projection on the merus of the chelipeds; non-enlarged chelipeds; and the presence of strap-like epipods on the third maxilliped and first and second pereiopods. With a total length of about 6-7 mm, Acanthanas pusillus is one of the smallest known caridean shrimps.
