Calliopsis coloradensis Cresson, 1878


Scientific Name: Calliopsis coloradensis Cresson, 1878

Common Name: Calliopsis coloradensis


Calliopsis coloradensis Cresson, 1878: 63 [♀, ♂].

     Lectotype ♀ [designated by Cresson 1916: 115]. USA, Colorado, by Ridings or Morrison [ANSP no. 2187].

Calliopsis coloratipes fedorensis Cockerell, 1909: 28 [♀]. Synonymy by Cockerell (1921: 14).

     Holotype ♀. USA, Texas, Fedor, 21 September 1897, by Birkman [USNM no. 40096].

Calliopsis coloradensis fedorensis Cockerell, 1921: 14. Emended name.


Taxonomic Notes: Shinn (1967: 843) indicated that one of the five paratypes of C. coloradensis is actually a female C. chlorops, though fortunately the lectotype selected by Cresson (1916) was this species. In its original appearance, C. coloratipes fedorensis was used when Cockerell (1909) first named and described this subspecies, but in later works he (i.e., Cockerell, 1921) used C. coloradensis fedorensis, suggesting that his original usage was a mistake (Shinn (1967: 842) attributed the name to a misidentification), or that he allied it more closely with C. coloradensis. However, as the name C. coloratipes fedorensis not only appears in print (i.e., Cockerell 1909) but also on the type specimen which apparently was not examined by Shinn (1967), it seems more appropriate to record it as a synonymy of C. coloradensis, with credit Cockerell (1921). Calliopsis coloratipes Cockerell, 1898 [which does not occur in Canada] was originally named in a key (with short description provided in the key) to bees of New Mexico as C. flavifrons Smith, race coloratipes Cockerell, 1898, though Cockerell later considered it a subspecies of C. coloradensis (Cockerell 1900) indicating that this form differed from C. coloradensis by the extent of maculation on the clypeus of the female; the type material was a male specimen collected on 21 August [no year provided] by T.D.A. Cockerell in Mesilla, New Mexico [CAS no. 15399, Shinn indicated UofC Riverside]; see Cockerell (1898). Cockerell (1906, 1908, 1921) subsequently had considered it a full species, but in the latter work suggested it was “at least a good subspecies”; Shinn (1967) considered it a good species.

DNA Barcode Index Number (BIN)BOLD:AAK2214

This BIN is seemingly shared with C. chlorops Cockerell (only a single specimen has yielded a DNA barcode sequence). As other C. chlorops specimens have not yielded DNA (n=12), this DNA barcode might be based on a misidentification of C. coloradensis.

Diagnosis: In Canada, C. coloradensis is most similar to C. chlorops and C. andreniformis, all three species lacking the pale metasomal maculations present in Nomadopsis Ashmead (i.e., represented in Canada by C. australior Cockerell,C. barri Rozen, and C. scitula scitula Cresson). The female of C. coloradensis has maculated tegula and pale apical fimbria of tergum 5, both features which distinguish it fromC. andreniformis which have unmaculated tegula and dark brown apical fimbria of tergum 5. Females of C. coloradensis usually have dark brown to reddish mandibles and a dark labrum which are unmaculated, or if maculations are present, they are small and basal in position on the mandible, and small and medial on the labrum, while females of C. chlorops have large pale maculations on the labrum and basal 1/3 to ½ of the mandible.

The male of C. coloradensis and C. chloropslack the dense, velvety hair patches on the scutellum and metanotum which is present in C. andrenidormis, and both species have the tegula maculated, while C. andreniformis does not. The male of C. coloradensis has the fore tibia much more extensively yellow than C. chlorops, in which is largely brown on the posterior surface.
