Genus Palpomyia Meigen, 1818

Type species

Ceratopogon flavipes Meigen, 1804 ; by original designation.

Diagnosis

Wing with 2 radial cells, costa extending at least ⅔ wing length, but not to apex. Fore femur slender to swollen, usually with stout ventral spines; mid and hind femora slender, often with ventral spines; fifth tarsomeres with or without 2 ventro-lateral rows of stout bristle-like setae; female claws equal, small to enlarged, with or without small, basal inner tooth. Female abdomen with paired internal tergal apodemes and 2 seminal capsules. Male genitalia with prominent cerci; gonocoxite simple or with lobe; aedeagus

conical or triangular, with well developed basal arms; parameres fused or divided, usually with welldeveloped basal apodemes (de Meillon & Wirth 1991).

Remarks

There are no universally recognized subgenera of Palpomyia ; however, four species groups have been proposed for this genus: distincta group, flavipes group, lineata group and tibialis group ( Grogan & Wirth 1975, 1979; Spinelli et al. 2009).
