Mesonotum covered with fine, short, procumbent hairs. Two pairs of postsutural, well developed dorsocentral bristles, with another stunted pair discernible in front. Unfortunately, majority of thoracic and scutellar bristles broken off, ratios thus unknown. Prescutellars very thin, comparatively long, — yet black, hair-like, thin bristles hardly recognizable against black base. Pleurae glabrous, except sparsely hairy meso- and sternopleurae. Tw r o vestigial prothoracic, and a strong, long, meso- and sternopleural bristle each. Of three pairs of scutellar bristles, only left lateral present, others discernible only by their points of emergence. On lower portion of fore coxae 3, and on middle ones 2, strong, curved bristles. Antero- and postero-ventral rows of bristles of fore femora consisting of sparsely spaced but long bristles. Dorsal preapical bristle of middle tibiae well developed. Wing two and a half times longer than wide. Ratio of penultimate and ultimate sections of vein m as 1 : 2,3. Distance between two crossveins twice as great as length of posterior crossvein. Marginal bristles of abdomen sparsely spaced, strong, long. First tergite almost glabrous, with but one group of hairs each laterally on posterior portion. Surstyli (Fig. 4 : B) thin, apically proclinate at right angles, sharply distinct from ninth (?) tergite. Dimensions: total length 3,8 mm; length of thorax: 1,6 mm; length of wing: 3,5 mm. Distribution: Ecuador: Guayas Chilcales. 1. Aug. 1955. leg. LEVI CASTILIO (holotype </')• Location of type: U. S. National Museum, Washington. As a peculiarity, the pattern resembles more that of the female of the nominate species than of the male. It differs from the male principally by the dark stripe of the frons, the preponderantly snow-white pleurae and haltères, the different coloration of the legs and the deviating shape of the surstyli.
