Abstract
The atyid shrimp Caridina linduensis Roux, 1904, has not been reported since its description more than a century ago. We here redescribe and figure this poorly known species based on new material from its type locality, Lake Lindu, Central Sulawesi, Indonesia. Two new species, C. dali sp. nov. and C. kaili sp. nov. are also found in this lake and they are described and illustrated. Compared to C. linduensis, C. dali sp. nov. is distinguished by its relatively shorter rostrum which only overreaches the end of basal segment of antennular peduncle and the fewer teeth on the incisor process of the mandible. Caridina kaili sp. nov. can be separated from C. linduensis by its extremely short rostrum, which reaches almost or just reaches the end of the basal segment of the antennular peduncle, proportionately stouter second pereiopod and larger egg size. The two new species also prefer different habitats; C. linduensis is a true lake inhabitant, C. dali sp. nov. can be found both in the lake itself and associated streams while C. kaili sp. nov. is an obligate stream species.
