(Figs. 22, 39)  
Holotype male, labeled: ‘‘ MEXICO, Coah [uila], Hwy./ 57, 15 mi. SE. Saltillo,/ 7000’ 12 Sept. 1982 C. &/ L. O’Brien & G. Wibmer’ ’, ‘‘ HOLOTYPE / Odontocorynus / procerus/ Prena’ ’ (California Academy of Sciences, on longterm loan to CWOB).  
Paratypes 2 males, 4 females: Mexico, Coahuila, 15 mi [24 km] SE Saltillo, 7000’ [2135 m], 12.9.1982, C.W. & L. O’Brien, G. Wibmer (CWOB 1, USNM 1); Nuevo León, Hwy. 58, 32 mi [51 km] W Linares, 6000’ [1830 m], 11.9.1982, C.W. & L. O’Brien, G. Wibmer (CWOB 2, JPPC 2).  
 Description. Total length 4.2–4.8 mm, standard length 3.9–4.4 mm; body elongate, derm black, scales elongate, dingy white, not forming pattern (Fig. 22); pronotal punctures dense, interspaces with trend to longitudinal ridges; prosternum channeled, its lateral edge interrupted by subapical constriction; elytral apices rounded conjointly and covering pygidium. Male: rostrum curved weakly and rather evenly, flank punctate coarsely throughout, anteantennal portion 0.33X length of rostrum; scape lamellate and gradually widened, first desmomere approximately 1.5X longer than second, distal desmomeres increasingly asymmetrical, dorsally expanded and lamellate, club elongate-ovate, as long as width of eye, basomere excised and with distinct conical process; anterolateral margin of pronotum with tubercle; ventrite 1 depressed, without setose fascicle; tibiae normal, without additional subdistal tooth; tarsomeres normal, without specialized setae; aedeagus as in Fig. 31, apex pointed, basal portion of internal sac one-half as long as apodemes, median and distal portions with armature consisting of numerous anvil-shaped denticles. Female: rostrum curved moderately at base, distal portion less curved, glabrous, flank with punctures gradually decreasing in size toward apex, anteantennal portion 0.47X length of rostrum; first desmomere approximately 1.5X longer than second, club ovate, approximately as long as first desmomere; tibiae normal, without additional subdistal tooth.   
 Distribution. Northeastern Mexico, Sierra Madre Oriental: Coahuila, Nuevo León (Fig. 39).   
 Temporal occurrence. September [2 dates].   
 Plant association. None recorded.   
 Specific epithet. A regular Latin adjective, first and second declension, meaning elongate.   
 Discussion. Odontocorynus procerus is very closely related to O. falsus, which occurs further north. These species differ chiefly in male character states of the antenna, i.e., size of the club and shape of the scape. I have seen another undescribed species of this complex that is intermediate between O. procerus and O. latiscapus. Females may be identified by their dingy white vestiture (usually yellow in O. falsus) and distributional range.
