Genus Pelastoneurus Loew, 1861

(Fig. 14E)

DIVERSITY. — 5 species (2.9-5.5 mm).

MORPHOLOGY, ECOLOGY AND DISTRIBUTION

Rather small to large species, with a characteristic bulging clypeus and a strongly plumose antennal (arista-like) stylus (Fig. 14E). Sixty of the 67 Pelastoneurus specimens were collected by sweep net, all but three specimens exclusively in swamp forests. Contrary to Cheiromyia pennaticornis, Pelastoneurus species seemed to prefer well-lit places where they were encountered mostly on low leaves of broad-leaved shrubs and herbs, and on leaf litter. As with C. pennaticornis, representatives of this genus, and the larger species in particular, appeared very agile and hard to collect with a net.
