A systematic review of the aleocharine genus Diaulota Casey is presented. Diaulota is redescribed, and eight species are recognized, one of which, D. alaskana Ahn, is a new species. Late-instar larvae of D. densissima Casey, D. fulviventris Moore, and D. harteri Moore are redescribed and late-instar larvae of D. aokii Sawada and D. uenoi (Sawada) are described for the first time. Genoplectes Sawada is synonymized under Diaulota Casey. A lectotype is designated for D. densissima. A key is provided for separation of the known species of Diaulota, and illustrations of diagnostic features are presented. |
