Three new phytotelma mosquitoes of the genus Topomyia (Diptera: Culicidae) from Katibas, Lanjak-Entimau, Sarawak, Malaysia

Three new species belonging to the subgenus Topomyia of the genus Topomyia are described under the name of Topomyia (Topomyia) katibasensis, To. (Top.) chaii and To. (Top.) nicksoni. The adults and pupae are described in detail and illustrations of the male genitalia and pupae are provided. Partial descriptions and illustrations of their fourth-instar larvae are also provided based on associated larval exuviae of the species. These species occur in the secondary rain forest along Katibas River in the Lanjak-Entimau Wildlife Sanctuary at elevation of approximately 200 m. The larvae of these species breed in the leaf axils of phytotelma plants, Pandanus sp., Phrynium sp. and arrowroot (Marantaceae). The new species described in the present paper are attributed to Miyagi and Toma
