Family Asilidae 

Subfamilies found in Wyoming: Asilinae, Brachyrhopalinae  , Dasypogoninae  , Dioctriinae  , Laphriinae  , Leptogastrinae  , Stenopogoninae  , Stichopogoninae  , Trigonomiminae  , and Willistonininae 

Key to Subfamilies [adapted from Artigas & Papavero (1988); Dikow (2009b)]

1 Abdominal tergite 1 five or more times as long as wide; alula (axillary lobe of authors) reduced in size or lacking ( Fig. 2AView FIGURE 2), and pulvilli lacking; abdominal sternite 1 extending about halfway back under tergite 2........... Leptogastrinae Schiner, 1862 

- Abdominal tergite 1 no more than four times as long as wide; usually both alula ( Fig. 2B, C, DView FIGURE 2) and pulvilli present, although alula maybe reduced in size ( Fig. 2DView FIGURE 2); abdominal sternite 1 confined to area beneath tergite 1......................... 2

2 Fore tibiae with an apical spur; one of the spines at the apex of the ventral side of the fore tibiae differentiated, enlarged and stouter than remaining spines, or if not noticeably larger, twisted and sigmoid; prosternum dissociated by a membranous area from proepisternum................................................................................... 3

- Fore tibiae without an apical spur; all apical spines on fore tibiae straight, or if one is slightly curved then it is not thickened or sigmoid; prosternum either dissociated from proepisternum or fused to it......................................... 4

3 Proximal prothoracic, mesothoracic, and metathoracic tarsomeres longer than two following tarsomeres combined.................................................................................... Dasypogoninae Macquart, 1838 

- Only proximal prothoracic and metathoracic tarsomeres longer than two following tarsomeres..................................................................................................... Brachyrhopalinae Hardy, 1926 

4 Veins R 2+3 joining R 1 before R 1 meets C, with cell r 1 closed; vein R 4 maybe strongly sinuate and arched forward after separation from R 5; cells m 3 and cup closed before wing margin ( Fig. 2BView FIGURE 2)............................ Laphriinae Macquart, 1838 

- R 2+3 joining R 1 before R 1 meets C ( Fig. 2CView FIGURE 2) or at C ( Fig. 2DView FIGURE 2); R 4 not unusually arched and sinuate; cells m 3 and cup open to wing margin or one of the two closed, or both closed ( Figs. 2C and DView FIGURE 2)................................................ 5

5 Veins R 2+3 joining R 1 proximal to end of R 1, with cell r 1 thus separated from wing margin and closed ( Fig. 2CView FIGURE 2); either anepisternum (mesopleuron of authors) with at least one strong bristle on its dorsoposterior angle, or katatergite with a vertical row of bristles or bristly setae...............................................................Asilinae Latrielle, 1802.

- R 2+3 ending in C ( Fig. 2DView FIGURE 2); neither a strong bristle present on the dorsoposterior angle of anepisternum, nor a row of bristles present on the katatergite................................................................................6

6 Prosternum dissociated from proepisternum by a membranous area.............................................. 7

- Prosternum fused to proepisternum, forming a precoxal bridge................................................. 8

7 At least some of the median ommatidia distinctly larger...................... Willistonininae Artigas & Papavero, 1991  .

- All ommatidia of the eye are the same size................................................................. 9

8 Three to four antennal segments; occiput and pronotum dorsally generally with strongly differentiated bristles; female acanthophorites with spines on ovipositor................................................... Stenopogoninae Hull, 1962  .

- Four to six antennal segments; occiput without strong bristles; pronotum dorsally with fine pile or bristly hairs; female acanthophorites without spines on ovipositor.............................................. Dioctriinae Enderlein, 1936 

9 Frons narrowed at level of insertion of antennae and then suddenly and widely diverging towards apex, which is extremely shallow (eyes much more distant at vertex than at antennal level); face without tentorial pits or grooves, flat above and prominent below or very gibbose; lateral eye margin sinuate; posterodorsal corner of metepimeron bare; abdomen slender; female terminalia with ventral keel and spines............................................. Stichopogoninae Hardy, 1930  .

- Frons approximately of same width at level of antennal insertion and vertex, the latter excavated (eyes not noticeably more distant at vertex than at antennal level); face with pronounced tentorial pits or grooves extending well beyond eye margin; lateral eye margin not sinuate; posterolateral corners of metepimeron with short setae; abdomen very short, usually three-quarters or less width of wing; female terminalia simple, tubular, without spines.................. Trigonomiminae Enderlein, 1914  .
