Caridina Lanzana , A New Troglobitic Shrimp from Somalia (Crustacea Decapoda)

Abstract

During the 12th Biological Expedition in Somalia (27 July-11 September 1969; see PARDI, 1976), undertaken under the auspices of the Centro di Studio per la Faunistica ed Ecologia Tropicali of the Con- siglio Nazionale delle Ricerche, Florence (Director Prof. L. Pardi), some very interesting troglobitic shrimps were collected. These shrimps belong to the family Atyidae and prove to represent an undescribed species of the genus Caridina. The strong reduction of the eyes shows that the shrimps are true troglobites; thus far only three troglobitic species of the genus Caridina were known.
