Description

This species is distinguished from congeners by the following combination of characters: Small shore flies, body length 1.20–1.95 mm. 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 0.31–0.39; M vein ratio 0.38–0.40.

Male terminalia (Figs 15–18): Epandrium in posterior view (Fig. 15) V-shaped with ventrolateral margin rounded and curved medially to base of surstyli; epandrium in lateral view (Fig. 18) somewhat narrowly rectangular on dorsal half than abruptly projected and angled anteriorly before taper posteroventral to base of surstyli; cerci in posterior view (Fig. 15) approximate dorsally then extended laterally to form an inverted V, each cercus robustly developed, medial margin distinctly sinuous, lateral margin shallowly and mostly evenly curved, bearing setae throughout length, especially medially and with very long setulae apically at expanded apex; cercus in lateral view (Fig. 18) lunate on dorsal third, then narrowed, linear before expanded, truncate apex; surstyli (ventral extensions of epandrium) in posterior view narrow, broader at base, tapered to apex, apical 1/3 shallowly recurved and very slightly spatulate, bearing several short setulae; surstylus in lateral view (Fig. 18) tapered on basal third, thereafter ventrally parallel sided and shallowly curved, apical fourth bearing several short setulae; aedeagus in ventral view (Fig. 16) elongate, narrowly ovate, bullet-like; very slightly tapered apically, in lateral view (Fig. 17) elongate, nearly parallel sided, apex bluntly rounded; phallapodeme in lateral view (Fig. 17) triangular, keel moderately tapered to form a triangular; gonite in ventral view (Fig. 16) bar-like, mostly parallel sided except for short, lateral expansion at apex; gonite in lateral view (Fig. 17) generally elongate, moderately wider basally, thereafter tapered gradually toward apex, apex produced as a lateral and ventral process, lateral process bearing 2 setulae, apical, process longer, bearing 1 setula.

Type material

The holotype male Allotrichoma deonieri is labeled “USA. V[IRGINI]A. Spotsylvania: Rappahannock River[,] 38°18.8'N, 77°32.5'W), 14 Aug 2006, D. & Wayne N.

Distribution

(Fig. 20) Nearctic: United States (Florida, Louisiana, Maryland, Mississippi, Tennessee, Virginia, West Virginia).

Etymology

The species epithet, deonieri, is a genitive patronym to honor one of the collectors of this species, D. L. Deonier, a long-time student of shore flies. Dick is not only our friend and colleague but an excellent field biologist. His collecting efforts have greatly assisted our research on shore flies.

Remarks

Although most records of this species are from the drainage of the Mississippi River, including nearby tributaries, the records from Maryland and Virginia represent a completely different drainage system.
