Diagnosis.
This species is distinguished from congeners by the following combination of characters: Small to moderately small shore flies, body length 1.70-2.40 mm.
Head: Frons dull, heavily microtomentose, 2-toned, mostly tan with some faint golden reflections on posterior 2/3, anterior 1/3 (from level of fronto-orbital setae anteriad), gray. Antenna mostly yellow to yellowish orange, anterior portion of pedicel and basodorsal area of basal flagellomere with some blackish coloration; arista with 5 dorsal rays. Face at narrowest point about equal to combined length of pedicel and basal flagellomere; face densely microtomentose, microtomentum with shiny to pearly luster, mostly white but with considerable gold coloration in antennal grooves and extended laterally onto parafacial; parafacial not markedly differing from middle of face in color, more golden dorsally, becoming whiter ventrally; parafacial with slight to considerable ventral dilation; parafacial 2-3 times wider ventrally than dorsally; gena relatively short, less than 1/4 eye height; gena-to-eye ratio 0.12-0.14.
Thorax: Mesonotum mostly dull, densely microtomentose, concolorous with posterior 2/3 of frons; pleural area blackish gray. Anterior margin of wing lacking spine-like setae; costal vein ratio 0.36-0.43; M vein ratio 0.56-0.62. Forefemur lacking row of 9-10 short, stout setae along apical half of anteroventral surface; forefemur with a row of 7-9, well-developed, evenly spaced posteroventral setae, each equal to width of femur; tibiae mostly yellowish; basal tarsomeres yellow, apical 1-2 brown.
Abdomen: Tergites 1-4 bicolored, subshiny to dull, dark gray medially, gray lateroventrally; tergites 3-4 of male subequal in length, tergite 4 not unusually longer, tergite 3 not produced ventrolaterally; dorsum of tergite 5 of male not darker than preceding tergites and usually with distinct, semicircular, grayish areas laterally; tergite 5 of male in dorsal view blunt, truncate, bearing row of 6-10, distinctly larger setae along extreme posterior margin with posterodorsal orientation; tergite 5 of male also gray on posterior 1/2-1/3; sternites 3-4 of male with dense row of setulae along posterior margin; sternite 5 as 2 subtriangular sternites. Male terminalia (Fig s 119-122): Epandrium not connected dorsally above cerci, in posterior view (Fig. 119) tapered ventrally to an acutely pointed apex under which lies cordate-shaped, laterally flanged anterior margin (Fig. 119); epandrium in lateral view (Fig. 120) slightly curved anteroventrally, pointed apically, and with subapical ledge that also ends ventrally in a point, bearing large, subapical setae laterally (Figs 119-120); gonite in lateral view rod-like, shallowly curved (Fig. 122); aedeagus in lateral view (Fig. 122) shallowly sinuous, bifurcate apically, anterior process sclerotized, posterior process longer, wider, membranous, apex complicated with gill-like folds laterally, apex slender, recurved anterodorsally giving appearance of rounded apex; phallapodeme with extended flange fan-like (Fig. 122); hypandrium in lateral view sinuous (Fig. 122), in posterior view deeply Y-shaped.

Remarks.
This species is distinguished from Polytrichophora prolata in having a smaller body (body length of 2.40 mm or smaller). In addition, male tergites one through four are bicolored (mostly blackish brown dorsally in contrast with the lateroventral surface being gray), male tergite five is truncate and is gray on the posterior one-third, and male sternites three and four have a dense patch of setulae along the posterior margin. Structures of the male terminalia (Figs 119-122) are unique within the genus in having the ventral margin pointedly rounded, without two apical processes.
