Notiocoenia pollinosa Mathis 1980: 18  .—Lizarralde de Grosso 1989: 59 –60 [list, Argentina].— Mathis and Zatwarnicki 1995: 250 [world catalog].

Diagnosis. Because this is the only known species of the pollinosa  group, the diagnosis of the latter, as cited previously, will adequately serve to distinguish specimens of this species. Should additional species of this speciesgroup be discovered, character states of the male terminalia will undoubtedly distinguish them from the present species. Small to moderately small shore flies, body length 1.98–2.56 mm; generally shiny, dark brown dorsally.

Head ( Figs. 21–22View FIGURES 21 – 23): Frons width-to-length ratio 0.36–0.38; coloration of frons mostly pale brown with some faintly olivaceous to greenish tinges. Antenna unicolorous, black. Coloration of face unicolorous, whitish gray to silvery gray; antennal groove shallowly impressed. Eye height-to-width ratio 0.86–0.88; gena-to-eye ratio 0.11– 0.13; gena pale brown; well-developed genal seta 1.

Thorax ( Fig. 23View FIGURES 21 – 23): Mesonotum and scutellum concolorous, shiny, bronzish brown, except extreme anterior margin of mesonotum dull, grayish. Pleural areas gradually becoming paler brown ventrally, grayer, particularly forecoxa and katepisternum. Wing palely infuscate, pale brown, appearing dull; with 2 white spots on either side of crossvein dm-cu; costal vein ratio 0.14–0.16; M vein ratio 0.58–0.61. Legs unicolorous, black; fore- and hindfemora appearing swollen. Halter brownish yellow, unicolorous.

Abdomen: Subshiny anteriorly, becoming distinctly shiny posteriorly; coloration grayish black anteriorly, becoming very dark greenish black posteriorly; female tergites becoming progressively longer posteriorly, also narrowing with gradual taper toward posterior end; male tergite 4 subequal to combined length of tergites 2 and 3; male tergite 5 subtrapezoidal, bluntly rounded apically, length about equal to length of tergite 4; male tergite 4 produced ventrally to acutely pointed apex; male sternite 4 subquadrate, becoming densely setose medioposteriorly. Male terminalia ( Figs. 24–26View FIGURES 24 – 26): Epandrium generally setulose, in posterior view ( Fig. 24View FIGURES 24 – 26) with dorsal 2 / 3 as an inverted U, more thinly developed dorsally, in lateral view ( Fig. 25View FIGURES 24 – 26) dorsal arch of inverted U more thinly developed, thereafter ventrally in lateral view gradually becoming wider to level of ventral margin of cercal cavity, ventral 1 / 3 in posterior view ( Fig. 24View FIGURES 24 – 26) flared laterally as bluntly rounded, lateral projections, posterior and anterior margins nearly parallel, posterior margin straight; ventral epandrial margin, which is probably the fused surstylus, obtusely angulate with a V-shaped medial notch and partial medial suture; cerci free in cercal cavity, not fused with epandrium, semihemispherical, short, subequal to ¼ length of epandrium and fused surstyli; aedeagus in lateral view ( Fig. 26View FIGURES 24 – 26) elongate, conspicuously wider on basal half, apical portion narrowed, slender, pointed apically; gonite produced anteroventrally as curved parallel-sided slender process.
