The Australian species of the genus Coelioxys Latreille are revised. Six species are recognized: Coelioxys albolineata Cockerell, 1905; Coelioxys froggatti Cockerell, 1911; Coelioxys reginae Cockerell, 1905; Coelioxys weinlandi Schulz, 1904 and two new species: Coelioxys julia sp. n. and Coelioxys tasmaniana sp. n. Three names are synonymized: Coelioxys biroi Friese, 1909 syn. n. and Coelioxys albolineata darwiniensis Cockerell, 1929 syn. n. under Coelioxys albolineata, and Coelioxys victoriae Rayment, 1935 syn. n. under Coelioxys froggatti. Species descriptions and redescriptions, illustrations, distribution maps, floral records and a key to both sexes of all species are provided., Léo Correia da Rocha-Filho., and Obsahuje bibliografii
In this paper the strictly attaphilous Central- and South American genus Phoxonotus Marseul, 1862 is revised. Based on the structure of their antennal cavities, the species of Phoxonotus are newly split into two subgenera: Phoxonotus Marseul, 1862 and Alienosternus subgen. n. (type species Saprinus venustus Erichson, 1834). The subgenus Phoxonotus contains three species: Phoxonotus (P.) tuberculatus Marseul, 1862 (French Guyana, Suriname, Brazil: Pará, Mato Grosso), P. (P.) lectus Lewis, 1902 (eastern Peru) and the newly described P. parvotuberculatus sp. n. (Guatemala, Costa Rica). The subgenus Alienosternus subgen. n. contains two species: Phoxonotus (Alienosternus) venustus (Erichson, 1834) (Brazil: Bahia) and P. (Alienosternus) fryi Lewis, 1879 (Brazil: Rio de Janeiro and Bahia). P. tuberculatus Marseul, 1862 is synonymized with P. suturalis Lewis, 1907, syn. n. Lectotype of Phoxonotus fryi Lewis, 1879 is designated. Genitalia of the males for the species for which they are available are illustrated, most type specimens are imaged and scanning electron micrographs of P. tuberculatus provided. Mouthparts and sensory structures of the antennal club of P. tuberculatus are depicted., Tomáš Lackner., and Obsahuje bibliografii
A revision of the genus Angulaphthona Bechyné, 1960 is provided, with a description of Angulaphthona confusa sp. n. from the Democratic Republic of Congo, and A. rossii sp. n. from Sierra Leone. The following synonymies are proposed: Angulaphthona latipennis (Pic, 1921) = A. latipennis zambeziensis (Bechyné, 1959) syn. n. and Angulaphthona pelengensis Bechyné, 1960 = A. exalta Bechyné, 1960 syn. n. The precedence of the name pelengensis is discussed. Angulaphthona violaceomicans (Chen, 1936) comb. n. (transferred from Aphthona) from Sri Lanka is established, and some hypotheses to explain the presence of the genus outside Africa are put forward. A key to the seven known species is supplied, with microphotographs of diagnostic characters, including male and female genitalia.
