Published: October 2020

A fully annotated catalog of genus- and species-group names of Neotropical Lauxaniidae (Diptera: Lauxanioidea) is presented, providing details of references to these names in literature, and providing additional details such as distributions, generic combinations, synonymies, misspellings and emendations, information on types, notes on unusual situations, etc. As this catalog is meant to supplement the older Catalog of the Diptera of America North of Mexico, to complete the cataloging of the New World Lauxaniidae, “Neotropical” is herein inclusive of everything south of the United States, and the Nearctic parts of Mexico are not separately distinguished. The catalog is organized alphabetically within each of the three lauxaniid subfamilies, Eurychoromyiinae, Homoneurinae and Lauxaniinae, treating 91 available genus-group names, of which 77 represent valid genera. In the species-group, the catalog treats 441 available species-group names, of which 391 represent valid Neotropical lauxaniid species, 39 are invalid, three are valid but extralimital lauxaniids, five are valid but removed from Lauxaniidae, and two are new replacement names for two homonyms outside Lauxaniidae. The following nine new genera are described, based on previously described species: Elipolambda Gaimari & Silva (type species, Sapromyza lopesi Shewell, 1989), Griphoneuromima Silva & Gaimari (type species, Sapromyza frontalis Macquart, 1844b), Meraina Silva & Gaimari (type species, Lauxania ferdinandi Frey, 1919), Myzaprosa Gaimari & Silva (type species, Myzaprosa mallochi Gaimari & Silva), Paradeceia Silva & Gaimari (type species, Sapromyza sororia Williston, 1896b), Pseudodeceia Silva & Gaimari (type species, Lauxania leptoptera Frey, 1919), Sericominettia Gaimari & Silva (type species, Minettia argentiventris Malloch, 1928), Zamyprosa Gaimari & Silva (type species, Sapromyza semiatra Malloch, 1933), and Zargopsinettia Gaimari & Silva (type species, Minettia verticalis Malloch, 1928). The following four new replacement names in the species-group replace junior homonyms: Myzaprosa mallochi Gaimari & Silva (for Sapromyza spinigera Malloch, 1933, nec Malloch, 1925), Pseudogriphoneura mallochi Silva & Gaimari (for Minettia infuscata Malloch, 1928, nec Sciomyza infuscata Wulp, 1897), Xenochaetina hendeli Silva & Gaimari (for Allogriphoneura robusta Hendel, 1936, nec Helomyza robusta Walker, 1858), Zamyprosa macquarti Gaimari & Silva (for Sciomyza nigripes Blanchard, 1854, nec Sapromyza nigripes Macquart, 1844). The following six genus-group names are new synonyms: Allogriphoneura Hendel, 1925 (= Xenochaetina Malloch, 1923), Bacilloflagellomera Papp & Silva, 1995 (= Stenolauxania Malloch, 1926), Haakonia Curran, 1942 (= Xenochaetina Malloch, 1923), Homoeominettia Broadhead, 1989 (= Allominettia Hendel, 1925), Paraphysoclypeus Papp & Silva, 1995 (= Physoclypeus Hendel, 1907), Tibiominettia Hendel, 1936 (= Allominettia Hendel, 1925).
