HOLOTYPE: United States. Male holotype from Carlsbad, New Mexico, July 26, 1938 (Bjorkman), in the American Museum of Natural History.

Original description:
Muma, 1951: 69-70:

MALES: Total length, 19.0 to 30.0 mm.

	LENGTH	WIDTH
Chelicerae	5.2- 8.0 mm.	2.6-4.0 mm.
Propeltidium	2.5- 3.9	4.2-6.6
Palpi	14.0-22.0
1st legs	12.0-18.0
4th legs	20.0-30.0

Coloration in alcohol similar to that of palpisetulosus Fichter except the markings on the propeltidium are faint and the legs and palpi are unmarked.
Structure similar to that of palpisetulosus except the movable finger in lateral view exhibits no anterior tooth and only one intermediate tooth that arises on the distal margin of the principal tooth. In dorsal view traces of the apparently missing teeth can be seen. This species also differs in having the fondal notch little more than half as wide as the base of the fixed finger, the ectal row of fondal teeth graded I, III, II, IV, in size, the propeltidium wider than long by a ratio of 1 to 1.6, and two, short, flattened ctenidia on the first post-spiracular abdominal sternite.

DISTRIBUTION:

PUBLISHED RECORds: Arizona: Tucson, one male (0. Bryant). Texas: Big Bend Park, August, 1947, one male (Fritz Putlitz).

nOTES: Muma (1951) in a key to males of the palpisetulosus group, attributed the following characters to Eremobates nodularis Muma: Metatarsus of palpus without scopula; abdominal ctenidia distinct, broad, bladelike, and two in number. He commented that a study of the illustration and description of Eremognatha guenini Roewer indicates these species are closely related, suggesting that this species can be separated from guenini by the possession of two ctenidia on the first post-spiracular abdominal sternite. He observed that Roewer also does not report a mesoventral groove of the fixed finger for guenini.
