E t y m o l o g y: Named after the Magdalena Mountains in New Mexico ( USA ), the type locality. D e s c r i p t i o n: Male, hind wings absent, 2,2 mm . Body oval, convex, elytra broadest in the middle, pronotum 1,5 times wide as long. Pubescence yellow and not very dense, with only erect hairs. Punctation of the pronotum coarse, distance between the punctures in the middle of the surface like the diameter. Punctation of the elytra (basal third) like that of the pronotum. Eyes conical, head above the eyes wide as the pronotum between the anterior angles. Antennae rather short, 11-segmented with a 3- segmented club. ( fig. 1 ). Pronotum 1,5 times broader than long, anterior callosity thickened, with a little prominent tooth. Tooth on the margin of the pronotum in the middle, sides behind the tooth straight except slightly concave in front of the posterior angles. Elytra oval, convex, broadest close to the middle, humeral callus absent. C o m m e n t:Verysimilarto Cryptophagus difficilis CASEY, 1900 and it differs only in the shape of the parameres and its setae ( C. difficilis ( fig. 3 ): two long setae on the apex, C. magdalenamontanus ( fig. 2 ): three long setae on the apex). The widespread C. difficilis is in some cases (WOODROFFE & COOMBS 1961) fully winged, but the writer saw only wingless specimens. Similar, but fully winged are C. discendens CASEY, 1900, described from Arizona , furthermore recorded from Colorado . Also similar is C. fumidulus CASEY, 1900 with wings developed in some cases ( California , Utah ). D i s t r i b u t i o n: As far as known restricted on the Magdalena Mountains in New Mexico ( fig. 8 , 9 and 10). A wider distribution in the mountains ranges of New Mexico is conceivable, also in the neighbouring states, but probably vicarious with C. difficilis CASEY, 1900 and C. discendens CASEY, 1900.
