Description

This species is distinguished from congeners by the following combination of characters: Small to moderately small shore flies, body length 1.75–2.15 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. Pleural area lacking stripes. Wing with costal vein ratio 0.25–0.31; M vein ratio 0.42–0.50. Legs blackish brown to black; midtibia bearing numerous, erect setae along dorsal surface.
Abdomen: Male 5th sternal flap in lateral view (Fig. 67) broadly developed to it apex, bearing approximately 15 apical setulae; 5th medial process in lateral view (Fig. 67) narrow, digitiform. Male terminalia (Figs 63–66): Epandrium in posterior view (Fig. 63) rounded dorsally, constricted laterally at base of surstyli; epandrium in lateral view (Fig. 64) somewhat rectangular dorsally with anterior and posterior margins parallel sided, ventral portion with an anterior bulge and a narrow, sharp incision at about level or base of surstylus; cerci in posterior view (Fig. 63) approximate dorsally then extended laterally to form a lyre-like structure that curves laterally than ventrally and medially, apex of cercus bearing 4 short setulae; cercus in lateral view (Fig. 64) shallowly sinuous, nearly parallel sided, apex slightly expanded, bluntly rounded; surstylus (ventral extensions of epandrium) in posterior view (Fig. 63) as relatively wide at base third, thereafter ventrally abruptly narrowed, especially along medial margin, to form an elongate process that is slightly spatulate apically, apical portion bearing several short setulae; surstylus in lateral view (Fig. 64) moderately narrow, slightly expanding with apex obliquely pointed and bearing several short setulae; aedeagus in ventral view (Fig. 65) elongate, narrowly ovate, very slightly tapered apically, in lateral view (Fig. 66) elongate, nearly parallel sided, apex bluntly rounded; phallapodeme in lateral view (Fig. 66) triangular, keel abruptly tapered to narrow, digitiform apex; gonite in ventral view (Fig. 65) bar-like, slightly wider basally, apex with short, lateral process, apex bearing setula, in lateral view (Fig. 66) wide basally, gently but distinctly arched, tapered to apical point.

Type material

The lectotype female of Discocerina simplex Loew, here designated to preserve stability and make more universal the use of this name, is labeled “[United States.] M[arylan]d./Loew Coll./simplex m[ihi]. [handwritten]/Type 11150 [red; number handwritten]/Prop. of Harvard Univ. [yellow]/LECTOTYPE ♀ Discocerina simplex Loew by Mathis & Zatwarnicki 2011 [red].” The lectotype is double mounted (minuten in a block of cork), is in good condition (abdomen removed, dissected, stored in glycerin in an attached microvial), and is deposited in the MCZ (11150).

Distribution

(Fig. 68) Nearctic: Canada (Ontario), United States (Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Maryland, Massachusetts, Michigan, Minnesota, New Jersey, New York, Ohio, Texas, Vermont, Virginia, West Virginia). Palearctic: Austria, Bulgaria, China (Tibet), Czech Republic, France, Hungary, Israel, Italy, Morocco, Poland, Spain, Russia (European Territory), Switzerland, Yugoslavia.

Natural history

Deonier (1965[10]: 501) found this species to be “occasional” in mud shore and sand shore habitats but rare in sedge meadow and Eragrostis mat habitats. Runyan and Deonier (1979)[13] produced the only illustrations of immature stages, including an egg, the cephalopharyngeal skeleton of the third instar larva, and the puparium.

Remarks

This species has a Holarctic distribution, and Palearctic specimens have been named at least three different times, with Allotrichoma simplex being the senior synonym. The junior synonyms in chronological order are: Allotrichoma filiforme Becker (1896)[16], Allotrichoma trispinum Becker (1896)[16], and Allotrichoma dahli Beschovski (1966a)[20]. In Europe, there is also a very similar species, Allotrichoma strandi Duda, that differs only slightly but apparently consistently from this species. In males of Allotrichoma simplex, the cercus has four apical setulae, compared to three in Allotrichoma strandi, and the mesonotal stripes are more evident in Allotrichoma strandi than in Allotrichoma simplex.
In the Nearctic Region, this is a common species that may have the most widespread distribution.
