Palaemonetes karukera Carvacho, 1979, a junior synonym of Leander paulensis Ortmann, 1897 (Decapoda, Palaemonidae)

Palaemonetes karukera Carvacho, 1979, a junior synonym of Leander paulensis Ortmann, 1897... Palaemonetes karukera Carvacho, 1979 was described from specimens collected in a low salinity mangrove canal on the Caribbean island of Guadeloupe, but no further specimens have been reported upon since his original description. Recently, the species was transferred to Palaemon Weber, 1795 in the reappraisal of De Grave & Ashelby (2013) of selected Palaemonidae genera. Although the species has generally been accepted as valid, the illustrations in Carvacho (1979) are not totally informative and raise doubt regarding its taxonomic position as a member of the genus Palaemon , as some characters are very reminiscent of those characterizing the genus Leander Desmarest, 1849. However, the clearly illustrated branchiostegal suture (Carvacho, 1979, fig. 2A) would maintain the species in Palaemon . In view of the potentially conflicting information in Carvacho (1979), we herein re-studied the type series of Palaemonetes karukera to check the generic placement of the species.

Abstract

Palaemonetes karukera Carvacho, 1979 was described from specimens collected in a low salinity mangrove canal on the Caribbean island of Guadeloupe, but no further specimens have been reported upon since his original description. Recently, the species was transferred to Palaemon Weber, 1795 in the reappraisal of De Grave & Ashelby (2013) of selected Palaemonidae genera. Although the species has generally been accepted as valid, the illustrations in Carvacho (1979) are not totally informative and raise doubt regarding its taxonomic position as a member of the genus Palaemon , as some characters are very reminiscent of those characterizing the genus Leander Desmarest, 1849. However, the clearly illustrated branchiostegal suture (Carvacho, 1979, fig. 2A) would maintain the species in Palaemon .
