T y p e m a t e r i a l: Holotype ♂: " Arizona: Graham Mts. , May 18 1969, K. Stephan leg [ FSCA] . Paratypes: 2♂♂, 1♀ with the same data as the holotype [ FSCA, cES] ; 1♀: " Arizona Graham Mts. , 9200 ft., April 25 1971, K. Stephan leg [ FSCA]."

E t y m o l o g y: Named after the Graham Mountains in Arizona ( USA) where the types were collected.

D e s c r i p t i o n: Male, 1.8 mm, hind wings absent, humeral callus nearly absent, with small tooth. Reddish-brown with legs and antennae paler, eyes of normal size. Punctation fine and moderately dense on head and pronotum, less dense on elytra (basal third). Covered with yellowish and decumbent pubescence. Pronotum hardly wider as long. Anterior callosity short but prominent, forming a hook. Lateral tooth in the middle, lateral margin concave before the tooth and convex behind the tooth. Rim of the margin indistinct before and distinct behind the tooth. Elytra strongly elongated. Legs more stout, antennae slender without any features, segment IX and X slightly transverse.

C o m m e n t: Typical species which is similar to C. stephani ( fig. 7 View Fig ) and very similar to C. bussi ESSER, 2017 ( fig. 6 View Fig ). C. stephani has a strongly elongated pronotum, C. bussi a less elongated pronotum which is more elongated as in grahammontanus with more convex posterior margin. Legs and antennae are in grahammontanus more slender than in bussi. Cryptophagus bussi was described from the Magdalena Mountains in New Mexico. So far known, the species seems to be restricted to this mountain range. It is obvious, that C. grahammontanus is also restricted to mountain range of the Graham Mountains.
