Description
Description. This species is distinguished from congeners by the following combination of characters: Small to moderately small shore flies, body length 1.35-2.30 mm (Fig. 1). Head: Medial facial carina above facial prominence shallow; labella broad, fleshy, shorter than mediproboscis; clypeus microtomentose, usually gray. Thorax: Presutural supra-alar seta present. Wing with costal vein ratio 0.27-0.33; M vein ratio 0.38-0.44. Abdomen: Male 5th sternal flap in lateral view (Fig. 4) shallow but long, bearing numerous, tuberculate setae; 5th medial process (Fig. 4) elongate, shallowly curved, bearing 4-5 setulae apically. Male terminalia (Figs 3, 5-7): Epandrium in posterior view (Fig. 3) like an inverted, laterally rounded, almost oval U; epandrium in lateral view (Fig. 5) relatively narrow dorsally, becoming wider ventrally; cercus in lateral view (Fig. 5) essentially straight, widest dorsally, then narrowed but gradually becoming wider ventrally, ventral apex narrowly spatulate, long and apically curved setulae especially evident on ventral 1/4; cercus in posterior view (Fig. 3) as a elongate, pendulous, ventrally projected process, gradually becoming wider ventrally, apex irregularly spatulate (slightly curved laterally), bearing numerous, very long setulae along length and especially long at apical 1/4; surstyli (ventral extensions of epandrium) in posterior view as parallel, narrow processes that bear setulae on apical portion, apical portion very slightly broadened and turned laterally; surstylus in lateral view narrow, elongate, gently curved, apical portion not expanded, bearing setulae apically; aedeagus in ventral view (Fig. 6) elongate, narrowly ovate, slightly tapered apically, in lateral view (Fig. 7) elongate, shallowly and narrowly lunate; phallapodeme in lateral view (Fig. 6) narrowly triangular, keel shorter than length, almost digitiform; gonite in ventral view (Fig. 7) somewhat bar-like, lateral margin shallowly curved, especially basally and apically, with short, subapical process, apex of process bearing a setula, with a subapical, distinct, angulate notch and bearing a subapical setula; gonite in lateral view (Fig. 7) wide basally, gently curved and tapered toward apex, with a subapical, short process that bears a setula and an apical setula.
