The taxonomy, zoogeography and phylogeny of the genus Dicrotendipes Kieffer, 1913 (Insecta: Diptera: Chironomidae) are reviewed on a world-wide basis. Sixty-eight species names are considered valid; the type-species for the genus is Chironomus septemmaculatus Becker, 1908. / The taxonomy of 14 species recognized from the Afrotropical region is reviewed. The previously unknown larvae and pupae of D. fusconotatus (Kieffer), D. kribiicola (Kieffer), D. septemmaculatus and D. sudanicus (Freeman), and the pupa of D. cordatus Kieffer are described. / Fifteen species are recorded from the Neotropical region. The adult males of 9 new species are described; adult females are described for 2 new species; and pupae are described for 2 new species. A key is provided to identify Neotropical adult males. / A total of 17 species are recognized from the combined Oriental, Australian and Oceanian regions. Three species previously considered to be Dicrotendipes are removed: Ch. blandellus Kieffer, D. paxillus Guha, Chaudhuri & Nandi, and D. socionotus Guha, Chaudhuri & Nandi. Seven new species are described from the combined regions. In addition, the males and females are redescribed, and pupae and larvae described, for: D. candidibasis (Edwards), D. conjunctus (Walker) and D. pelochloris (Kieffer); adult males are redescribed for D. bilobatus Kieffer and D. tenuiforceps (Kieffer). The pupa and larva of D. flexus (Johannsen) are redescribed. Keys are provided for adult males, pupae and larvae. / Distributions of selected species are discussed and distribution maps are provided. The phylogney of Dicrotendipes species known in all 3 life stages is analyzed utilizing a Hennigian cladistic analysis and a computer program, PAUP. Results of the analyses are similar, and indicate that 3 major lineages occur within the genus, with at least 9 species groups. / Source: Dissertation Abstracts International, Volume: 48-03, Section: B, page: 0638. / Thesis (Ph.D.)--The Florida State University, 1987.
