Odontocorynus creperus Boheman

( Figs. 1, 9 , 39 )

Odontocorynus creperus Boheman 1844: 271 . Holotype male, labeled: ‘‘Typus’’, ‘‘ Odontocorynus / creperus S.’’, ‘‘64’’ (NHRS).

Odontocorynus limatulus Casey 1920: 434 . Syntypes 2, male, labeled: ‘‘Cuernavaca/ Mor. Mex./ Wickham’’, ‘‘CASEY/ bequest/ 1925’’, first specimen handwritten ‘‘limatulus/ Csy.’’, USNM type number 37913. New synonymy.

Odontocorynus subglaber Casey 1920: 434 . Holotype male, labeled: ‘‘ Puebla / Mex.’’, ‘‘CASEY/ bequest/ 1925’’, ‘‘TYPE USNM/ 37912 ’’, ‘‘subglaber/ Csy.’’ New synonymy.

Odontocorynus vernicicollis Casey 1920: 435 . Syntypes 2, male, labeled: ‘‘ Puebla / Mex.’’, ‘‘CASEY/ bequest/ 1925’’, first specimen handwritten ‘‘vernicicollis/ Csy.’’, USNM type number 37914. New synonymy.

Recognition. Male O. creperus and O. subvittatus differ from all congeners by the possession of a setose fascicle on the first ventrite. They can be distinguished reliably from each other by using the character states given in the key. Female

254 specimens may be very similar to O. latiscapus , O. procerus , and probably O. subvittatus [not studied]. In the material available for study, O. creperus differed from those other species by shorter desmomere 2, less crowded punctures on frons and pronotum, and often larger size.

Distribution. Mexico ( Fig. 39 ).

Type locality. Mexico, site not specified .

Material examined. MEXICO. Chihuahua ( USNM 2), Colima ( AMNH 1, USNM 8), Guerrero ( CWOB 1, USNM 2), Jalisco ( AMNH 14, CMNC 17, CWOB 13, TAMU 1), México D. F. ( CWOB 9, TAMU 5, USNM 61), Michoacán ( CWOB 9, JPPC 4, TAMU 1, USNM 2), Morelos ( CMNC 1, USNM 55), Nayarit ( CWOB 5), Oaxaca ( AMNH 1, CMNC 25, CWOB 1, TAMU 6), Puebla ( CWOB 2, TAMU 7, USNM 5), San Luis Potosí ( USNM 2), Sonora

( CMNC 1), Tlaxcala ( CMNC 5 , CWOB 2 , JPPC 2 , USNM 9 ) , Veracruz ( USNM 1 ). Total 267 specimens .

Temporal occurrence. Mid July to early October.

Plant association. Asteraceae : Tagetes sp. (3X), T. lucida (5X), Xanthocephalum benthamianum (12X). Fabaceae : Mimosa biuncifera (4X). Papaveraceae : Argemone sp. (3X).

Nomenclatural notes. Casey (1920) described O. limatulus , O. subglaber , and O. vernicicollis based on individual rather than interspecific differences.
