Micropotamia Carvalho, 1993 View in CoL

Type-species: Phaonia minuscula Albuquerque, 1955 , by original designation.

Diagnosis. Male holoptic, eyes pubescent; female dichoptic. Fronto-orbital plate slender in both sexes; female with proclinate orbital seta. Gena narrow, at most 1/10 of head height, and with strongly inclined genal seta. Arista pubescent, setae shorter at base. Dorsocentral setae 2+3, pre-sutural acrostichal setae in 3 series; pre-alar seta 1. Notopleuron bare. Anepimeron bare. Posterior spiracle small in both sexes, smaller than base of halter, margin bare. Veins bare, except costa. Subcostal gently curved on apical portion. Mid femur on ventral surface with 1 preapical seta. Hind tibia on posterior portion with 2 preapical setae; posterodorsal seta well developed on apical third (calcar). Hind coxa bare on apical posterior margin. Pulvilli yellow and claws black. Abdomen with translucent yellow tergites 1+2 and 3. First abdominal sternite bare. Male terminalia: distiphallus with small denticles. Female terminalia: sternite 8 developed; cerci longer than the hypoproct; spermathecae 3.

Distribution. Brazil, Costa Rica, Mexico.

Considerations. The identification key includes the males of all species, and the females of only four, because the males of Micropotamia amazonica , M. fuscisquama , M. minuscula , and Micropotamia fortuna sp. nov. could be associated with their female counterparts.
