Genus Hirtodrosophila Duda

Hirtodrosophila Duda 1923: 41 . As subgenus,

type species Drosophila carinata Duda ;

Grimaldi (1990), elevated to genus.

Dasydrosophila Duda, 1925 : unjustified replacement for Hirtodrosophila .

DIAGNOSIS: Eye from bare to having short, dense pilosity; anterior reclinate orbital seta small to minute; postocellar setae generally crossing; carina generally very short and narrow, nearly missing in some species; arista almost always with one ventral branch, near apex; basal flagellomere with long fine setulae in some species; cibarium with sclerotized hypopharyngeal bulb, reduced number of medial sensilla ( Grimaldi, 1990); oviscapt with simple margin or apical pegs differentiated, spermathecal capsule generally rounded, sclerotized; male: cerci not connected to epandrium; epandrium often with well-developed ventral lobe; surstylus often divided into dorsal and ventral lobes; hypandrium and aedeagus well developed but relatively simple.

TYPE SPECIES: Hirtodrosophila carinata Duda.

COMMENTS: The genus is probably paraphyletic with respect to Mycodrosophila Oldenberg , Paramycodrosophila Duda , and Zygothrica Wiedemann. Each of these particular genera appears to be monophyletic ( Grimaldi, 1987; 1990), but may be closely related to certain groups within Hirtodrosophila . There are some groups within Hirtodrosophila that appear to be monophyletic, such as the H. hirticornis group (defined by the large, projecting pegs at the apex of the oviscapt). If this is the case, there may need to be a division of some Hirtodrosophila into these other genera, with a more narrowly defined Hirtodrosophila (sensu stricto) for some. Any reclassification should ideally involve a revision of the world species as well as further phylogenetic study using morphological and molecular data.
