Two pairs of frontal setae. Gena, proboscis, and antennae are light to dark brown. Arista plumose.Palpi filiform. Females with a pair of interfrontal setae,two pairs of proclinate orbital setae (the upper one being very short), and one pair of reclinate orbital setae ( Figs. 1D , 2D , 3D ). One to two anterior anepisternal setae.The prealar seta shorter than the posterior notopleural seta. The apex of the scutellum is setulose ventrally. Prosternum bare. Dorsocentral setae 2+3.
