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 invalia Fallén, 1810), Homoneura maculipennis (Loew, 1847; Sapromyza Fallén, 1810), Poecilohetaerus suavis (Loew, 1847; Sapromyza Fallén, 1810). The following four species are removed from the family, three of which are put into the following new combinations Senopterina cyanea (Fabricius, 1805; Lauxania Latreille, 1804) (Platystomatidae), Dihoplopyga delicatula (Blanchard, 1854; Sapromyza Fallén, 1810) (Heleomyzidae), Pherbellia geniculata (Macquart, 1844b; Sapromyza Fallén, 1810) (Sciomyzidae). The remaining species, Sapromyza fuscipes Macquart, 1844b, is of uncertain family placement within the Muscoidea. The following new replacement names for species of Platystomatidae were necessary due to homonymy Senopterina gigliotosi Gaimari Silva (for Bricinniella cyanea Giglio-Tos, 1893, nec Lauxania cyanea Fabricius, 1805), and Rivellia macquarti Gaimari Silva (for Tephritis unifasciata Macquart, 1843 381, nec Macquart, 1835 465).The Chinese bees of the genus Anthidium Fabricius, 1804, are reviewed. Twenty-one species are confirmed to occur in China, five of which are described and illustrated as new Chinese endemics Anthidium (Anthidium) pseudomontanum Niu Zhu, sp. nov., A. (A.) pseudophilorum Niu Zhu, sp. nov., A. (A.) tasitiense Niu Zhu, sp. nov., A. (A.) xuezhongi Niu Zhu, sp. nov., and A. (Proanthidium) qingtaoi Niu Zhu, sp. nov.. The previously unknown female of A. (A.) kashmirense Mavromoustakis, 1937 and male of A. (P.) kashgarense (Cockerell, 1911) are described for the first time. Anthidium (A.) furcatum Wu, 2004 (junior primary homonym, nec Anthidium furcatum Ducke, 1908) is replaced with its valid and available synonym A. (A.) striatum Wu, 2004. New synonymies are also established for A. (A.) kashmirense Mavromoustakis, 1937 = A. https://www.selleckchem.com/products/as601245.html (A.) nigroventrale Wu, 1982, syn. nov., and A. (A.) florentinum (Fabricius, 1775) = A. (A.) helianthinum Wu, 2004, syn. nov. The non-Chinese Anthidium amabile Alfken, 1933 (junior primary homonym, nec Anthidium porterae var. amabile Cockerell, 1904) is unavailable and the available name Anthidium (Proanthidium) minimum Pasteels, 1969, is valid for this species. Updated synonymies and distributional data are provided for some widespread Palaearctic species including two now adventive in the New World. For Chinese species, the distribution and floral associations of each are provided along with illustrations and a key to the known species.The genus Olios Walckenaer, 1837 is revised, a generic diagnosis is given and an identification key to eight species groups is provided. Olios in its revised sense includes 87 species and is distributed in Africa, southern Europe and Asia. Three species groups are revised in this first part, an identification key to species for each group is provided, five new species are described and all included species are illustrated. The Olios argelasius-group includes O. argelasius Walckenaer, 1806, O. canariensis (Lucas, 1838), O. pictus (Simon, 1885), O. fasciculatus Simon, 1880 and O. kunzi spec. nov. (male, female; Namibia, Zambia, South Africa); it is distributed in the Mediterranean region, northern Africa including Canary Islands, in the Middle East, South Sudan, East Africa, and southern Africa. The Olios coenobitus-group includes O. angolensis spec. nov. (male; Angola), O. coenobitus Fage, 1926, O. denticulus spec. nov. (male; Java), O. erraticus Fage, 1926, O. gambiensis spec. nov. (male, female; Gambia), O. (Schmidt, 1971) comb. nov., Nolavia fuhrmanni (Strand, 1914) comb. nov., Nolavia helva (Keyserling, 1880) comb. nov., Nolavia stylifer (F.O. Pickard-Cambridge, 1900) comb. nov., Nolavia valenciae (Strand, 1916a) comb. nov., Nungara cayana (Taczanowski, 1872) comb. nov., Polybetes bombilius (F.O. Pickard-Cambridge, 1899) comb. nov., Polybetes fasciatus (Keyserling, 1880) comb. nov., Polybetes hyeroglyphicus (Mello-Leitão, 1918) comb. nov. and Prychia paalonga (Barrion Litsinger, 1995) comb. nov. One species is transferred from Olios to the family Clubionidae Wagner, 1887 Clubiona paenuliformis (Strand, 1916a) comb. nov.Details are provided on 16 land snail genera, eight freshwater molluscan species, one estuarine species, 47 land snail species and varieties from New Zealand, and a further three land snail species putatively from New Zealand, which were described by Frederick Wollaston Hutton between 1879 and 1904. Original primary type material of 54 species was located during the present study. Lectotypes are designated for Amphidoxa cornea Hutton, 1882, Amphidoxa jacquenetta Hutton, 1883, Amphidoxa perdita Hutton, 1883, Charopa cassandra Hutton, 1883, Cyclotus charmian Hutton, 1883, Fruticicola adriana Hutton, 1883, Gerontia cordelia Hutton, 1883, Gerontia pantherina Hutton, 1882, Microphysa pumila Hutton, 1882, Patula jessica Hutton, 1883, Patula lucetta Hutton, 1884, Patula sylvia Hutton, 1883, Patula tapirina Hutton, 1882, Pfeifferia cressida Hutton, 1883, Phrixgnathus celia Hutton, 1883, Phrixgnathus haasti Hutton, 1883, Phrixgnathus marginatus Hutton, 1882, Phrixgnathus phrynia Hutton, 1883, Rhytida australis Hutton,ermia Hutton, 1883 are treated as junior synonyms of Tasmaphena sinclairii (Pfeiffer, 1846), Phacussa fulminata (Hutton, 1882), Fectola infecta (Reeve, 1852) and Advena campbellii (Gray, 1834), respectively.
