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.
1904年被描述的阿蒂虾属林杜卡氏米虾（Caridina linduensis Roux），自其被描述以来已有一个多世纪，一直未再有报道。我们在此依据来自其模式产地印度尼西亚中苏拉威西省林杜湖的新材料，对这个鲜为人知的物种进行重新描述并配图。在该湖中还发现了两个新物种，即大理卡氏米虾（Caridina dali sp. nov.）和凯里卡氏米虾（Caridina kaili sp. nov.），并对它们进行了描述和绘图。与林杜卡氏米虾相比，大理卡氏米虾的区别在于其吻部相对较短，仅超过触角柄基部节的末端，且下颌切齿突上的齿较少。凯里卡氏米虾可通过其极短的吻部（几乎到达或刚好到达触角柄基部节的末端）、相对粗壮的第二对步足和较大的卵大小与林杜卡氏米虾区分开来。这两个新物种也偏好不同的栖息地；林杜卡氏米虾是真正的湖泊栖息者，大理卡氏米虾既能在湖中也能在相关溪流中发现，而凯里卡氏米虾是专性溪流物种。
