E t y m o l o g y: Named after the Jemez Mountains where the types were found.

D e s c r i p t i o n: Male, 2 mm, reddish-brown, hind wings absent, eyes moderately small. Covered with long and woolly, whitish hairs. Pubescence slightly erected, in the posterior half mixed with shorter and decumbent hairs (pubescence double). Beetle moderately shiny. Legs more stout, tarsi 5-jointed, hind tarsi 4-jointed (not in female). Fore tarsi (segments I to IV) slightly widened (not in female). Antennae moderately slender, 11-segmented with a 3-segmented club. Segments IX and X slightly transverse, segment XI drop-shaped. Segments I to VIII long as broad or indistinct longer. Segment III longer as wide, segment I nearly spherical, broader than the remaining, segment II broader than segments III to VIII. Pronotum moderately wider than long, punctuation strong and dense. Anterior callosity not prominent, with a little tooth oriented backwards. Lateral tooth placed in the middle of the lateral margin. Elytra elongated, oval, with strong punctuation less dense than on pronotum (basal third). Parameres as in fig. 3.

C o m m e n t: General shape like a few other species, e.g. Cryptophagus difficilis CASEY, 1900 or C. magdalenamontanus ESSER, 2017. C. difficilis is currently not known from New Mexico. C. magdalenamontanus is restricted to the Magdalena Mountains. Both have a anterior callosity forming a more strong tooth. Their pubescence is more erected than in C. jemezmontanus .

Cryptophagus jemezmontanus nov.sp. is very similar to C. sanmateomontanus nov.sp. ( fig. 2 ). There are no good features to distinguish the species without the parameres ( figs. 3, 4 ). So far known, C. jemezmontanus is restricted to the Jemez Mountains.

D i s t r i b u t i o n: Known only from the Jemez Mountains in New Mexico ( USA).
