Mutilla (Sphaeropthalma) canella Blake, 1871 . Trans. Amer. Ent. Soc. 3: 239. Holotype 3: Texas (ANSP). Mutilla rugulosa Fox, 1899 . Trans. Amer. Ent. Soc. 25: 240. Lectotype (designated by Mickel, 1928 by referencing the “ type ” [Art. 74.5, ICZN, 1999]),Ƥ: Southern New Jersey, September (ANSP).
Mutilla infensa Melander & Brues, 1903 . Biol. Bull. 5: 24. Lectotype (designated by Mickel, 1928 by referencing the “ type ” [Art. 74.5, ICZN, 1999]), Ƥ: Woods Hole, Massachusetts ([WSUC]).
Diagnosis. FEMALE. The female of this species can be separated from other Dasymutilla by the head shape and mesosomal sculpture. The head is slightly angulate posterolaterally ( Fig. 14 View FIGURES 9 – 23 ), the mesonotum has transverse carinae situated antero-laterally to the scutellar scale, and the propodeum is strongly asperated dorsally and posterolaterally. MALE. The male of this species can be separated from other Dasymutilla by the exceptionally large and deep propodeal reticulations. The following characters are also helpful for identification: the head and mesosoma are covered entirely with black setae, there is a seta-filled pit on S2, there are silver setae on T5–7, and the cuspis is roughly 0.5x the free paramere length ( Figs 52, 53 View FIGURES 36 – 71 ).
Description of male genitalia ( Figs 52–55 View FIGURES 36 – 71 ). Free length of paramere dorsally curved apically, with ventral brush of long dense setae basally, remainder having scattered short sparse setae; paramere laterally kinked in basal 0.2, apices noticeably divergent. Cuspis slightly laterally compressed, tapering apically, ~0.55 × free-length of paramere, having a few scattered long setae, those on inner surface posteriorly directed. Densely setose basal lobe present. Digitus laterally curved internally, tapering slightly at apex, asetose, ~0.35 × free-length of paramere. Penial valve emarginated anterodorsally, ventral margin bidentate apically, teeth separated, unidentate medially; having longitudinal row of setae at apex and subapically on external margin.
Length. Females: 3.5– 7 mm; males: 4–7.5 mm.
Host. Unknown.
Distribution. This species is found in the northeastern USA and southeastern Canada.
Material examined. Type material. Holotypes: Mutilla (Sphaeropthalma) canella , USA: Texas, 13 ( ANSP); Lectotypes: M. rugulosa , USA, New Jersey, Southern New Jersey, 1Ƥ ( ANSP); M. infensa , USA, Massachusetts, [Barnstable Co.], Woods Hole, 1Ƥ ( WSUC); Paralectotypes, M. rugulosa , USA, New Jersey, Southern New Jersey, 2Ƥ ( ANSP); M. infensa , USA, Massachusetts, [Barnstable Co.], Woods Hole ( WSUC) Other material. USA: Connecticut: New Haven Co., Bethany, 13, 24.VI.1958 ( CUIC); Massachusetts: Barnstable Co., Dennis, 13, 4.VII.1954, J.W.

Williams ( EMUS); Michigan: Livingston Co., E.S. George Reserve: 6Ƥ, 30.VI.1950, D.G. Shappirio ( EMUS; UMMZ); 2Ƥ, 21.VII.1950, D.G. Shappirio ( UMMZ); Washtenaw Co., Ann Arbor, 6Ƥ, 23.VII.1950 ( UMMZ); New York: Suffolk Co., Gardiners Island: 13, 3.VIII.2008, R.G. Geolet ( AMNH). At least 40 additional specimens ( USA: CT, MA, MI) were examined ( CASC, DGMC, UMMZ).
Remarks. The phylogenetic results show a close affiliation between this species and D. macilenta . We believe these are distinct taxa, however, because of morphological differences (propodeal sculpture) seen in both sexes, differences in male genitalia, and geographic ranges.
The female of this species [as D. rugulosa (Fox) ] was initially placed in the D. quadriguttata species-group by Mickel (1928), because of the angulate postero-lateral head angles.
