A new species of Austinixa Heard and Manning 1997 (Decapoda: Pinnotheridae) and new records of A. felipensis (Glassell, 1935) from the Mexican Pacific

Abstract

A new species of the pinnotherid crab genus Austinixa from La Cruz de Huanacaxtle, Nayarit, Mexico is described. The new species is closely related to Austinixa roblesi Palacios Theil and Felder, 2020, however these can be distinguished mainly by the shape of the male pleon and telson, gonopod and chelae. In addition, four new records of distribution of Austinixa felipensis Glassell, 1935 are added. The species is known previously from the type locality to the north of the Gulf of California and the Pacific coast of El Salvador and Nicaragua. The new collection sites are located on the eastern coast of the Gulf of California and the states of Nayarit and Jalisco, Mexico.
