Diaugia Perty, 1833

Diaugia Perty 1833: 187, type species: Diaugia angusta Perty, 1833 (by monotypy).

Diaugia ; Townsend 1936: 30 (key to genera of Zeliini ), Townsend 1939: 77 (diagnosis), Guimarães 1971: 101 (as ' Diaughia ', catalogue, in Zeliini ), Tschorsnig 1985: 100 (as ' Diaughia ', citation, male terminalia characterization, in Dexiini ).

Diagnosis.

Diaugia differs from other South American Dexiini by the following combination of characters: eye bare; arista densely long plumose; no facial carina; parafacial bare; proepisternum bare; intrapostalar seta absent; 2 katepisternal setae; katepimeron (barette) setulose anteriorly; costal spine undeveloped; R1 without setulae; base of R4+5 setulose dorsally and ventrally; abdominal syntergite 1+2 and tergite 3 without median marginal setae (but females have a pair of median marginal setae on tergite 3) and all tergites without discal setae (but some ground setulae rather developed middorsally); male abdomen conspicuously elongate (although not caudate as in Uramya Robineau-Desvoidy and Trichodura Macquart).

Among Dexiini , Diaugia undoubtedly resembles the other genera formerly included in the extinct tribe Zeliini (sensu Guimarães 1971, 1975). If valid today, this tribe would include 11 genera, all them monotypic except for Zelia Robineau-Desvoidy with nine species. Although Diaugia may be distinguished from other " Zeliini " and Dexiini (former paragraph), as well as each of the former " Zeliini " genera may bear a set of diagnostic characters, a discussion about the validity of each of these 10 monotypic genera is extremely necessary. On the other hand, to achieve a reliable treatment of these generic names (if valid or not), a detailed and comprehensive revision including types and non-types of all the 11 genera is much required.
