Type Material
Holotype: “Say's specimens cannot be located in North American (Muma 1951) or European (Muma 1970) type depositories and are presumed lost. We hereby designate the following: male neotype from Highway 205c, Byers, Colorado, 17-VII-1973 by J. 0. Brookhart; female allotype from Castle Rock, Colorado, 27-VI-1973 by J. 0. Brookhart. Both are deposited in the American Museum of Natural History, New York, N. Y” (Brookhart & Muma, 1981, p. 292).
Measurements: “Males: Total length, 15.0 to 26.0 mm. Chelicerae, 4.5-7.2 mm length; 2.2-3.7 mm width. Propeltidium, 2.2-3.5 mm length; 3.5-5.8 mm width. Palpi, 14.0-20.0 mm. 1st legs, 11.0-17.0 mm. 4th legs, 18.0-26.0 mm” (Muma, 1951, p. 73).
Palpal Description: “Palpal papillae 55.6-40.5±13.8-18.1” (Brookhart & Muma, 1981, p. 292).
Ctenidia Description: “Ctenidia absent (Fig. 8)” (Brookhart & Muma, 1981, p. 292).
Operculum Description: “Female genital opercula triangular with the anterior margins slightly separated, somewhat bowed posteriorly, and the posterior edge curved (Fig. 14). A/CP 4.84±40.37” (Brookhart & Muma, 1981, p. 292).
Chelicerae Description: “Males with mesoventral groove narrow, flared on the ventral side, and a deep basal cup (Fig. 2, 3, 5, 6). Basal flange elongate forming a shallow ventral hollow the entire length of finger. Mesal tooth medium” (Brookhart & Muma, 1981, p. 292).
Diagnosis: “Species statistics were compiled from 4 populations ranging from Denver, Colorado southward to Lamar, Colorado. There is more inconsistency in this species than in any other member of the group. Occasionally a male will have a ctenidia and a female will have a scopula. The species may be highly variable or presently undergoing speciation. The population from Peyton Road near Colorado Springs was variant in many respects and may well represent a still unrecognized sibling species. Muma's records (1951) probably are valid for all of Colorado, Kansas, Oklahoma, Nebraska, North and South Dakota, and northern New Mexico east of the Rocky Mountains. His records from Idaho and Utah probably are E. docolora new species. The single record from Kirkwood, Missouri may be an error in locality label. Since this study has demonstrated that species of the pallipes group are geographically isolated, the synonyms of pallipes suggested by Muma (1951, 1970) must be considered to be largely invalid. At the present time only Galeodes subulata Say can be validly cited as a synonym of pallipes. On the bases of type examinations and original descriptions the following are Mexican species: Gluvia cinerascens L. L. Koch (1842), Gluvia formicarius C. L. Koch (1842), Datames lentiginosus Kraepelin (1899, 1901), and Eremostata dinamita Roewer (1934). Eremostata arizonica Roewer (1934), and Eremostata californica Roewer (1934) are recognized here as separate distinct species, but E. californica may well be the female of Eremothera sculpturata Muma (see Muma 1962), so is not considered here” (Brookhart & Muma, 1981, p. 292).
