Diagnosis: Abdominal maculae do not meet abdominal margin; maculae on tergites 3&4 arcuate with medial edge flattened and usually broadly contacting anterior edge; markings unlike any other species ( Figs 6A & C View FIGURE 6 ).

Redescription:

Body Length: 6.7–10.5mm; Wing Length: 6.3–9.2mm

Head: Frons dark with light pollenose fascia (in male it runs along ventral edge of where eyes meet, in females it is ½ the length between the antennae and ocelli) and dark pile; face light with dark vitta ¼–⅓ the width of the face, usually not reaching antennal socket, face with light pile, dark pile lateral to the eye; gena light ( Fig. 6C View FIGURE 6 ) with light pile and usually some dark pile below eye; occiput dark, covered in light pollen, pile light; scape and pedicel light to dark, flagellomere dark.

Thorax: Scutum dark, may appear shiny or metallic, pile light; scutellum light to dark with darker lateral edges, light pile along anterior edge and dark pile elsewhere; wing cells br and bm entirely bare, cell c bare from base to ¾, r 1 bare at base and cup bare at base and along vein CuP ( Fig. 6D View FIGURE 6 ); haltere light; pro- and mesofemora ⅓–½ dark basially, ½–⅔ light apically, metafemur ⅔–¾ dark basially, ¼–⅓ light apically, tibiae light, metatibia with dark band ¼ of the way from the apex, tarsii light, sometime dark anteriorly.

Abdomen: Maculae on tergite 2 large and oval, maculae on tergites 3&4 are arcuate, with medial edge widened, flattened and usually broadly contacting the anterior edge of tergite, sometimes meeting medially, maculae do not reach abdominal margin ( Figs 6A & C View FIGURE 6 ); sternites light with dark fasciae.

Male Genitalia: Surstylus more or less triangular in shape in lateral view, flattened posteriorly, long pile on dorsal, laterodorsal and posterodorsal sides, row of spines on posteromedial edge; cercus oval with long pile over entire surface; gonostylus boot-shaped with projection on posterodorsal surface that projects dorsally, pile on dorsal surface; basiphallus elongate, basally bent at 90 degree angle towards dorsum, apical end curved ventrally and is partly membranous with pile on dorsal side; distiphallus elongate, apical end flared out into horn, which is mostly sclerotized but membranous at apex with minute setulae dorsally, basally bent towards dorsum and slightly enlarged at bend ( Fig. 6B View FIGURE 6 ).

Intraspecific variation: Scutellum colour varies from light to dark; maculae on tergites 3&4 sometimes meet medially and sometimes are separated, medial edge usually broadly contacts anterior edge of tergite but if not then it comes close to anterior edge and edge of maculae are rounded; dark fasciae on sternites vary in width.

Etymology: The word creper   is Latin, meaning dark or obscure.

Distribution: Southwestern Canada (AB, BC) and western USA (AZ, CA, CO, ID, MT, NM, OR, SD, UT, WA, WY). ( Fig. 20A View FIGURE 20 )

Ecology: Collected on ponderosa pine ( Pinus ponderosa Douglas ex Lawson & C. Lawson   , Pinaceae   ), sierra willow ( Salix orestera C.K. Schneid.   , Salicaceae   ), willow ( Salix Linnaeus   , Salicaceae   ), chokecherry ( Prunus virginiana   , Rosaceae   ), Ross’ avens ( Geum rossii (R. Brown) Seringe   , Rosaceae   ), avens ( Geum Linnaeus   , Rosaceae   ), tall ragwort ( Senecio serra Hooker   , Asteraceae   ), threenerve goldenrod ( Solidago velutina DC.   , Asteraceae   ), rabbitbush ( Chrysothamnus Nuttall   , Asteraceae   ). Habitats listed on labels include “along timberline”, “creek margin” and “on tundra”. The specimen collected on the “tundra” was collected in Colorado at 3505m, so this is in reference to an alpine tundra habitat. Collected April to October, although much more frequently collected in July and August. Collected from elevations of 305m – 3688m, although most frequently collected from elevations above 2000m.

Discussion: Presumably Williston (1887) was referring to a specimen of D. creper   when he described the female from New Mexico as a second specimen in his description of lotus   . He noted there were differences but that it was “perhaps allied” with the female from Arizona that he described as lotus   . He describes the abdominal maculae of this second specimen as “more oblique, and strongly concave in front” and “more convex behind” and the gena as having a “black stripe”, which are characters more befitting of Snow’s description of creper   , which came some seven years later.

Three years before Snow formally described creper   in 1895 he described specimens as pauxillus ( Snow 1892)   . In his description of creper   he synonymizes his 1892 pauxillus   description with creper   . Snow is also the one who suggests Williston’s (1887) variety of lotus   is probably creper   .

In Curran’s monograph ( Curran 1925) he demotes S. creper   from the rank of species to a variety of S. lotus   . He claimed that there were no differences between the two except for the amount of interruption in the second and third abdominal bands. He believed it was just an extreme in coloration and did not warrant the rank of species. However, in the same paper he provides a redescription of lotus   and based on the characters discussed and illustrated (Plate VI: 51) it is clear that his concept of lotus   is not the same as Williston’s and he is actually describing creper   . In 1933, Fluke re-elevated creper   to the rank of species. Fluke states that at that time lotus   was only known from the type and that published records of lotus   probably refer to creper   . Fluke also notes that Curran was probably looking at specimens of creper   , not lotus   .

Fluke (1933) clearly distinguishes between these two species based on the abdominal markings, with lotus   having more straight bands and those of creper   being more arcuate. Fluke also places both species into Metasyrphus   and into the amalopis   group with other species currently recognized as Dasysyrphus   .
