description: Dasymutilla chionothrix Manley & Pitts, new species   
Holotype female, Mexico, Sonora, 10 mi SE Alamos, VI-29-63, F. D. Parker and L. A. Stange [UCDC].  
 Diagnosis of Female (Plate C3E). This species can be diagnosed by the following unique combination of characters. The integument of this species is a dark reddish color, clothed primarily with yellow setae and some contrasting black setae. The head is distinctly narrower than the mesosoma, the antennal scrobe is carinate, and a genal carina is absent. The mesosoma is longer than broad, having both a scutellar scale and a sinuate carina anterior to the scale, and the pygidium is longitudinally striate.   
 Description. Female: Length, 12–15 mm. Head. Reddish, clothed entirely with pale yellow setae; mandible acute at apex, with inconspicuous inner tooth about 0.3X distance from apex; clypeus transversely concave, anterior margin nearly straight; scape carinate, clothed with yellow setae; flagellomere I slightly longer than remaining segments; antennal scrobe distinctly carinate; front and vertex with coarse contiguous punctures, sculpture concealed by dense setae; gena with shallow contiguous punctures, genal carina absent; head 2.3–3.1 mm, distinctly narrower than mesosoma; head to mesosoma ratio about 0.70:1.   
 Mesosoma. Reddish, distinctly longer than broad (3.2–4.4 mm wide X 3.9–5.3 mm long), clothed almost entirely with pale yellow setae; scutellar scale present and prominent, with sinuate carina anterior to scale; dorsum with coarse contiguous punctures, concealed by setae; propodeum deeply reticulate, posterior face with dense brush of black setae.   
Legs dark reddish, with pale setae; hind femora distinctly flattened ventrally.  
 Metasoma. Reddish, clothed almost entirely with pale yellow setae; tergum I smooth and shining, with only shallow scattered punctures; tergum II with coarse contiguous punctures, sculpture concealed by dense setae; pygidium longitudinally striate; sternum I with sharp carina about 0.5X length of segment, produced posteriorly into sharp tooth; setae entirely pale yellow, except apical fringe of tergum I black, bordered by yellow, apical fringe of tergum II narrowly interrupted medially with black, and black setae medially on tergum III.   
 Male. Unknown.   
 Paratypes. 2♀, MEXICO, Morelos, Yautepec, VII-13-63, F. D. Parker and L. A. Stange (DGMC); Sonora, Guirocoba, VIII-24-33 (LACM).   
 Distribution. Mexico (Morelos, Sonora).   
 Etymology. From the Greek chion “snow” and thrix “hair,” in reference to the white setae of the metasoma.   
 Remarks. This species is known only from the female.
