Description
This species is distinguished from congeners by the following combination of characters: Small shore flies, body length 1.15–1.45 mm. Head: Frons mostly unicolorous, at most with narrow, anterior fronto-orbits slightly lighter in color, lacking distinctively colored ocellar triangle; pseudopostocellar setae subequal in length to ocellar setae. Pedicel with well-developed, proclinate, dorsal seta. Facial coloration sexually dimorphic, males unicolorous and darker; face with dorsal 2/3 between antennal grooves shallowly carinate, becoming more prominent ventrad of facial grooves, slightly tuberculate; clypeus mostly bare, black, subshiny; maxillary palpus blackish.
Thorax: Mesonotum generally dark brown; chaetotaxy generally well developed; prescutellar acrostichal setae much larger than other acrostichal setae and more widely set apart; presutural supra-alar seta well developed, length subequal to notopleural setae; katepisternum with 2 setae, 2nd seta smaller and inserted below larger seta. Wing mostly milky white; veins behind costa brownish; alular marginal setulae short, less than 1/2 alular height; costal vein ratio 0.34–0.44; M vein ratio 0.33–0.36. Legs: tibiae dark, concolorous with femora.
Abdomen: 5th sternite transversely narrow, shallowly arched, bearing numerous setulae. Male terminalia (Figs 75–78): Epandrium in posterior view (Fig. 75) uniformly and broadly as an inverted U, slightly broader ventrally and ventral apex abruptly curved medially; in lateral view (Fig. 76) moderately narrow, height 3X width, widest dorsally, dorsal surface slightly produced posteriorly, thereafter ventrally slightly tapered and shallowly curved anteriorly, ventral margin produced anteriorly as a short, pointed extension; cercus in posterior view (Fig. 75) becoming broader ventrally, ventral margin broadly rounded, dorsal margin slightly produced and pointed medially, in lateral view (Fig. 76) with anterior margin shallowly curved, posterior margin rounded, slightly narrower dorsally than ventrally; surstylus a rod-like, nearly horizontal, slender process that bears prominent setulae posteriorly; aedeagus in ventral view (Fig. 77) elongate, narrowly rectangular, almost parallel sided, base rounded, not cleft apically, in lateral view (Fig. 78) very shallowly curved, broadly elliptical, apex broadly rounded; phallapodeme in lateral view (Fig. 78) well developed, keel broadly triangular, apex broadly but asymmetrically rounded, in ventral view (Fig. 77) as a double T (2 cross bars); gonite in lateral view (Fig. 78) short, as high or higher than long, apical margin irregularly truncate, bearing 2–3 setulae, in ventral view (Fig. 77) short, more or less triangular; hypandrium in ventral view (Fig. 77) broadly U-shaped, arms angled posterolaterally, in lateral view (Fig. 78) with base slightly hooked, becoming wider apically, bearing numerous setulae along apical half.
Type material
The holotype male of Allotrichoma atrilabre Cresson is labeled “Lansdale [Montgomery County] P[ennsylvani]a[,] VII, 12, 1908 [12 Jul 1908]/♂/TYPE, Allotrichoma ATRILABRIS E.T. Cresson, Jr. [red; species and generic names handwritten]/Loaned by A.N.S.P.” The holotype is double mounted (glued to a paper triangle), is in poor condition (fore- and midlegs on right side and left wing missing; right wing, left 1st flagellomere, and right hindleg removed and glued to a second paper triangle; abdomen removed, dissected, structures stored in an attached microvial of glycerin), and is deposited in the ANSP (6320). Cresson (1926)[1] also listed two male and one female paratopotypes (ANSP).
The holotype male of Allotrichoma yosemite Cresson is labeled “Yosemite Valley[,] V,22,'08, [22 May 1908] Cal[ifornia]./♂/TYPE Allotrichoma YOSEMITE E.T.Cresson,Jr. [red; species and generic names handwritten]/Loaned by A.N.S.P.” The holotype is double mounted (minuten in a rectangular card), is in good condition (right wing torn; abdomen removed, dissected, the parts stored in an attached microvial of glycerin), and is deposited in the ANSP (6321). Cresson (1926)[1] also listed one male and eight female paratopotypes (ANSP).
