Diagnosis: Abdominal maculae cross abdominal margin; maculae on tergite 2 very small oval-shaped; maculae on tergites 3&4 transverse, narrow and slightly widened medially, narrow slightly towards margin ( Fig. 9A View FIGURE 9 ). Similar to D. venustus   ( Fig. 17A View FIGURE 17 ) however the maculae on tergite 2 are always small in D. limatus   , less than ¼ the width of the tergite, and are much larger in D. venustus   , greater than ⅓ the width of the tergite.

Redescription:

Body Length: 7.5–10.9mm; Wing Length: 6.8–10.4mm

Head: Frons dark with light pollenose fascia (in males it runs along ventral edge of where eyes meet, in female it is ½ or less the length between the antennae and ocelli, with a distinct separation medially) and dark pile; face light with dark vitta ⅓–½ the width of the face and reaches the antennal socket, face with dark pile, bare medially; gena dark with some light pollen ventral to eye, light and dark pile; occiput dark, covered in light pollen, pile light, some specimens with some dark pile; scape, pedicel and flagellomere dark.

Thorax: Scutum dark, may appear shiny or metallic, pile dark in males and light in female; scutellum light to dark with darker lateral edges, pile dark with some light pile along lateral edges to light with some dark on posterior edge; wing cell br bare basally and above spurious vein, bm bare on anterior ½–¾, r 1 bare at base and some with cup bare posterior to vein CuP ( Fig. 9C View FIGURE 9 ); haltere light; pro- and mesofemora dark on basal half, light on apical half, metafemur dark with light apical end, pro- and mesotibiae light, metatibia dark with light basal end, tarsi dark, pro- and mesotarsi with light ventral side.

Abdomen: Maculae on tergite 2 small, slender and oval, <¼ width of tergite, maculae on tergites 3&4 are transverse, slender and widen medially, narrowed toward margin, positioned anteriorly on the tergite, maculae cross abdominal margin ( Fig. 9A View FIGURE 9 ); sternites light with thick, dark fasciae.

Male Genitalia: Surstylus more or less oval in shape in lateral view, flattened with long pile on posterior side and spines on anteroventral side; cercus oval with long pile over entire surface; gonostylus triangular-shaped in lateral view, wide at base and elongated posterodorsal with small pointed projection on posterodorsal edge, posterior edge flares laterally, making it difficult to see in lateral view; pile on dorsal surface; basiphallus is greatly enlarged dorsally, fully sclerotized all the way around with no pile or spines; distiphallus is short with no enlarged area basally, apical end flared out into horn, which is mostly sclerotized but membranous at apex with no setulae dorsally ( Fig. 9D View FIGURE 9 ).

Intraspecific variation: Maculae on abdomen can be of varying thickness, however they are usually quite narrow.

Etymology: The word limatus   is Latin, meaning polished, refined.

Distribution: Canada (AB, BC, NT, NS, QC, YT), USA (AK, CO, MA, ME, NY, UT) ( Fig. 20D View FIGURE 20 )

Ecology: Collected on common cow parsnip ( Heracleum maximum   ). Collected from “sand dunes” and “outlet marsh” habitats. Collected April to September, although much more frequently collected from June through August. Collected from elevations of 320m – 3002m.

Discussion: The concept of limatus   has been applied consistently since Hine erected the name in 1922.
