This species is distinguished from other congeners by the following combination of characters: Small to moderately small shore-flies, body length 1.85-2.65 mm, generally black, subshiny to shiny species. Head: Frons black, very sparsely microtomentose, anterior half shiny, posterior subshiny, transition from shiny to subshiny gradual. Antenna black, densely microtomentose, appearing velvety black. Face black, sparsely microtomentose, antennal grooves and lateral areas shiny, otherwise subshiny, lacking prominent, vertical stripes; face bearing 2-3 larger facial setae, dorsal seta at about midfacial height, dorsomesoclinate; ventral seta just dorsad of epistomal margin, slightly dorsoclinate; parafacial blackish yellow; gena moderately high, gena-to-eye ratio 0.16-0.22. Thorax: Mesonotum uniformly sparsely microtomentose, black, subshiny; presutural supra-alar seta well developed; pleural area concolorous with mesonotum, subshiny black. Wing hyaline to very faintly infuscate, lacking pattern of spots; vein R4+5 extended at gradual to costa, not angulate subapically or bearing a stump vein; costal vein ratio 0.47-0.55; M vein ratio 0.60-0.62. Femora and tibiae black; Forefemur with posteroventral setae slender, not stout and peg-like; foretarsus with basal 2 tarsomeres white, tarsomere 3 darkened, apical 2 black; mid- and hindtarsus with basal 2 tarsomeres yellow, apical 3 tarsomeres blackish. Abdomen: Generally black, mostly subshiny to shiny, dorsum of tergites very sparsely and finely microtomentose. Male terminalia (Figs 3-6): Epandrium in posterior view (Fig. 3) generally vertically oval, each lateral arm narrow, almost parallel sided, acutely pointed ventrally, in lateral view (Fig. 4) with dorsal 2/3 rectangular, basal 1/3 almost twice width as dorsal portion, widest subventrally, apex broadly rounded, posteroventral portion bearing several larger setulae; cerci in posterior view (Fig. 3) elongate, narrowly semicircular, medial margin nearly straight, gradually tapered toward ventral apex, this apex acutely pointed, dorsal apex with medial short, digitiform extension, in lateral view (Fig. 4) semicircular; gonite in lateral view (Fig. 6) narrowly elongate, somewhat rod-like, ventral 1/3 narrower than dorsal 2/3, in ventral view (Fig. 5) very robustly C-shaped with medial concavity, wider than high; aedeagus in lateral view (Fig. 6) tubular, gradually tapered to apex, apex generally broadly rounded with very apex narrowed, curved anteriorly at nearly right angle; phallapodeme in lateral view (Fig. 6) very narrow, L-shaped, apex toward base of aedeagus acutely pointed, apex toward hypandrium slightly flared and truncate, in ventral view (Fig. 5) as an elongate hourglass, expanded at each apex and truncate; hypandrium in lateral view (Fig. 6) narrowed posteriorly, then abruptly expanded to

, this species is distinguished from congeners by the white forebasitarsomere, which is contrasted with the black, apical tarsomeres; the short gena (gena-to-eye ratio 0.10-0.14); and the shape of structures of the male terminalia (Figs 3-6).

<paragraph pageId="14" pageNumber="15">The distribution of this species is anomalously disjunct. Except for this species, which is found on the Indian Subcontinent, all other congeners occur in the New World, especially in tropical zones, which are many thousands of kilometers from India and Sri Lanka. This distributional anomaly prompts a number of questions. For example, is this species indeed a valid congener? If so, what is it related to? How did it come to be found on the Indian Subcontinent when other congeners occur in the New World? Although our responses to these and other questions are not wholly satisfactory, often being based on tenuous evidence, we offer some thoughts and observations.</paragraph>

Based on morphological evidence, both external and from structures of the male terminalia, we affirm that this is a congener within the genus
