Ceratina lucidula Smith, 1854 by original designation. Diagnosis. Minute bees (3-6 mm long); usually metallic (rarely with the metasoma red); body elongated, with a slightly petiolate metasoma, the first segment as elongate-triangular; integument with extensive impunctate smooth areas, especially on head (paraocular area above antenna and on gena, sometimes on the whole head) and on mesonotum; second submarginal cell narrowed, sometimes converging to a point anteriorly, becoming almost triangular ( Moure 1941 ; Michener 2007 ). Among the species of Ceratina (Ceratinula) occurring in South America, C. (C.) fioreseana Oliveira, sp. nov. is similar to C. (C.) manni , especially in the pattern of facial maculation (Fig. 8 ). However, it is easily distinguished by the smaller and slimmer body, the color of the legs, antennal scape, pedicel and first three flagellomeres (honey-yellow in Ceratina fioreseana sp. nov. and dark brown in Ceratina manni ); the integumental microsculpture on the paraocular region and on the upper part of the clypeus (smooth in Ceratina fioreseana sp. nov. and microreticulate in Ceratina manni ); the yellow genal stripe (following the orbit in the lower region in Ceratina fioreseana sp. nov. and on the upper portion of the head diverging upward from the orbit in Ceratina manni ). The male genitalia also differ widely between the species, especially in the structure and shape of the valves, gonostyle, S5, S6 and S7 (Figs 3A-F ; 7A-F ).
