Forty-one new species of Coniceromyia Borgmeier (Diptera: Phoridae), an identification key, and new distributional records for the species of the genus.

Forty-one new species of the mostly neotropical genus Coniceromyia Borgmeier are described. The descriptions follow the methodology of recent works on the genus taxonomy and illustrate habitus, foremetatarsus, wing, hind femur, and hypopygium for each species. Unique features of some species are also illustrated, including several male features possibly related to sexual selection such as processes on different tarsomeres of the foreleg. New records for the known species are presented, as well as an identification key for the species of the genus and maps with their updated distribution. Coniceromyia brandaoi Ament Amorim is synonymized with Coniceromyia plaumanni Borgmeier. Even though this work examined the Coniceromyia of the major collections of neotropical Phoridae, the high number of singletons and doubletons indicates that the real diversity of the genus may still be far from understood.

Taxonomic revision of the genus Hirotophora Brown et al. (Diptera: Phoridae) with the description of a new species from Chile.

The monotypic genus Hirotophora Brown et al. is revised, with a new species from Chile, Hirotophora chilensis sp. nov., described, and Chaetopleurophora dividua and Chaetopleurophora flavimarginata transferred to this genus. The addition of these species is based on the genus diagnosis, which is amended here, and on the synapomorphies recognized for Hirotophora. All species of the genus are extensively illustrated and new diagnostic characters are described. Females of Hirotophora are more structurally divergent than males, which show almost no conspicuous differences in the male terminalia among the species. This is an uncommon scenario for the subfamily Phorinae, and may relate to still-unknown life history particularities of the species of this genus.

Taxonomic revision of Coniceromyia Borgmeier (Diptera: Phoridae), with the description of three new species from Brazil.

The 55 known species of Coniceromyia are herein revised. Three new species from the Atlantic Forest in Brazil are described-C. apioneura, sp.nov., C. neofusca, sp.nov. and C. tanycrossa, sp.nov.-and fourteen species are redescribed. Most of the species have foreleg, wing, hind femur, and male terminalia illustrated. Characters previously unnoticed are described for the first time. Coniceromyia cubensis Brues, previously accepted as a synonym of C. latimana (Malloch), has its status reinstated. Taxonomic problems in the genus are addressed, including the condition of the damaged holotypes of C. boliviana Borgmeier and C. vespertilio Schmitz, and our inability to associate males with the female holotypes of C. arizonensis Borgmeier, C. fusca Borgmeier and C. grenadensis (Brues). The holotypes of Coniceromyia angularis Borgmeier & Prado and Coniceromyia laticosta Prado are considered to be lost.

FAMILY PHORIDAE.

The Phoridae recorded from Colombia are catalogued, totaling 226 species distributed in 19 genera and three subfamilies. For each species, distribution, hierarchic position and cited references are presented.

Taxonomic revision of the genus Chaetocnemistoptera Borgmeier (Diptera: Phoridae), with the description of five new species.

The Neotropical genus Chaetocnemistoptera is herein revised. Five new species are described-C. lobata, sp. nov., C. magdalena, sp. nov., C. phaeonota, sp. nov., C. pityropyga, sp. nov., C. trichopoda, sp. nov. The hypopygia of the previously described Chaetocnemistoptera palpalis (Borgmeier) and C. formosa (Borgmeier) are illustrated. The female holotype of Chaetocnemistoptera semifurcata (Borgmeier) could not be associated with any male specimen. A species identification key is provided and comments on the homology of structures and on species relationships are made.

Taxonomic revision of the genus Neopleurophora Brown (Diptera: Phoridae), with the description of thirty seven new species.

Thirty seven new Neotropical species of the phorid genus Neopleurophora are described­ N. acrensis, sp. nov., N. acrochaetopyga,sp. nov., N. atlantica, sp. nov., N. balbii, sp. nov., N. boliviana, sp. nov., N. brachypyga, sp. nov., N.brachytarsus, sp. nov., N. browni, sp. nov., N. carcharopyga, sp. nov., N. cauca, sp. nov., N. ceratopyga, sp. nov., N. chocoensis, sp. nov., N. colobopyga, sp. nov., N. costaricana, sp. nov., N. dichaeta, sp. nov., N. dicrodrilus, sp. nov., N. diffusa,sp. nov., N. dolichopyga, sp. nov., N. dorsimaculata, sp. nov., N. hymenodrilus, sp. nov., N. kleini, sp. nov., N. kungi, sp.nov., N. lamasi, sp. nov., N. manauara, sp. nov., N. marquesi, sp. nov., N. megalopyga, sp. nov., N. microssoma, sp. nov.,N. odontopyga, sp. nov., N. platypyga, sp. nov., N. polychaetopoda, sp. nov., N. prionotopyga, sp. nov., N. ptychodrilus,sp. nov., N. reginensis, sp. nov., N. scleropyga, sp. nov., N. setiventris, sp. nov., N. synaptodrilus, sp. nov., N. tanytarsus,sp. nov. The female holotypes of N. scutellata and N. scutellata var. jamaicensis could not be associated to any male specimen and there is no sufficient morphological evidence to consider either as different species. Neopleurophora setipes is redescribed and illustrated. The hypopygial morphology is studied in detail and the first illustrations of the phallus of the genus are presented. An identification key for the species of the genus is provided and groups of species are proposed.
