Remains known from only two workers collected in 1933.
Identification
Snelling (1995) - A characteristic that will separate D. wheeleri from all previously described North American Dorymyrmex: the sparsely pubescent frons, the hairs of which are separated from adjacent hairs by several times their own widths (in the paralectotype many of the hairs are separated by their own lengths or more). In the paralectotype the entire frons is smooth and shiny, but in the lectotype most of the frons is distinctly shagreened.
The head shape is about as in D. insanus: lateral margins weakly convex, vertex margin so weakly convex that it is nearly flat. The profile of the mesonotum is flat and with a distinctly sloping posterior face. The mostly convex basal face of the propodeum is abruptly depressed behind, to form a distinct transverse crease in front of the short, acute tubercle.
These two workers appear to be nanitic, and I have seen no specimens like them in any of the numerous collections of Dorymyrmex available from the Tucson area.

Description
Worker
Snelling (1995) - (mm) lectotype (paralectotype): HL 0.73 (0.62); HW 0.60 (0.51); SL 0.71 (0.59); EL 0.19 (0.17); TL 2.5 (2.2). Indices and ratios: CI 82 (83); SI 97 (96); Slz 117 (115); 01 26 (27); OMR 93 (85); IOR 153 (146).
Type Material
Snelling (1995) - This species was described from two workers collected by P. Klingenberg at "College P. A.," Tucson, Arizona, on 22 March 1933; a specific holotype was not designated. A female specimen in the MCZ collection, perhaps conspecific with the two workers, has a similar label, with identical data, and a label written by W.M. Wheeler; "Dorymyrmex pyramicus n. subsp."
The locality data as cited by Kusnezov are incorrect: the first line of the label reads "College P. K." on both samples. According to F.G. Werner (personal communication), P. Klingenberg collected specimens in Arizona and sent them to W.M. Wheeler. Apparently, when the specimens were mounted and the labels written, the notation "coil. P. K." (= collector P. Klingenberg) became "College P. K.," misquored by Kusnezov as "College P. A." A further distortion is that of Shattuck (1994), who translated the citation to read "College Park, Tucson."
Of the two syntypes, the larger is here designated lectotype; the second specimen is the paralectotype.
