abstract

  • A new monotypic genus, Glassella, is recognized from the tropical East Pacific for Pinnixa costaricana Wicksten, 1982. This genus shares with Alarconia Glassell, 1938, Indopinnixa Manning & Morton, 1987, Scleroplax Rathbun, 1893 and Pinnixa White, 1846, a carapace wider than long, and third pair of walking legs the longest. Glassella is distinguished from other genera by: MXP3 with ischium-merus pyriform, carpus larger than the conical propodus, and small digitiform dactylus inserted sub-distally on the inner face of propodus. The type species is redescribed and illustrated.
