Treatment

Cryptophagus sanmateomontanus nov.sp. ( fig. 2 View Fig , 4 View Fig )

T y p e m a t e r i a l: Holotype ♂: " USA: NM: Cibola Co., Mt. Taylor , pitfall trap, N35°15.21 W107°34.17, leg. R. J. Buss, 04.08.2017 " [cES]. GoogleMaps

Paratypes: 4♀♀ with the same data as the holotype [cBU, cES].

E t y m o l o g y: Named after the San Mateo Mountains where the types were collected.

D e s c r i p t i o n: Male, 2.5 mm, reddish-brown, hind wings absent, eyes moderately small. Covered with long and woolly, whitish hairs. Pubescence slightly erected in the anterior half, more erected in the posterior half and also with short 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 three-segmented club. Segments IX and X transverse, segment XI drop-shaped. Segments III to VIII more (segment III) or less (segment VIII) longer than wide. Segment I spherical, segment II less broad than I but broader than II. Pronotum hardly wider than long, punctuation strong and dense. Anterior callosity not prominent, with a little tooth oriented backwards. Lateral tooth placed nearly in the middle of the lateral margin. Elytra elongated, oval, with strong punctuation less dense than on pronotum (basal third). Parameres as in fig. 4. View Fig

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. sanmateomontanus .

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

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