Exallandra cinctifacies (Speiser)  

Very small slender dark species with small and rather variable yellow markings on thorax and abdomen.

In external structural characters, E. cinctifacies is extremely similar to the many species of Melangyna. However, the colour pattern and terminalia are strikingly different, and the reduction of the subscutellar fringe offers a convenient recognition character for both sexes. Generic separation of this species was reasonable for Vockeroth (1969). The distribution is disjunct from that of the typical and largest subgenus of Melangyna, but less so than that of the two small Papuan and Australian subgenera of the latter genus. These, however, have terminalia very little different in general structure from those of Melangyna s. str. and can be reasonably considered congeneric with them. Exallandra may be separated from Sphaerophoria by the much smaller genitalia and by the Syrphus-type abdominal colour pattern (Vockeroth 1969).
