Odontocorynus subvittatus Casey

( Fig. 38 )

Odontocorynus subvittatus Casey 1920: 435 . Holotype male, labeled: ‘‘ Omilteme ,/ Guerrero,/ 8000 ft. / elv. H. H. Smi [th]’’, ‘‘ Oi ’’, Champion’s handwriting ‘‘ Odont —/ creperus/ Boh’ ’, ‘‘CASEY/ bequest/ 1925’’, ‘‘TYPE USNM/ 37915 ’’, ‘‘subvittatus/ Csy.’’

Recognition. Casey recognized and distinguished this species from O. creperus based on character states that are not consistently different. All specimens that I have studied are males, and they share with O. creperus the setose fascicle on the first ventrite. These species differ from each other particularly by their suites of specialized setae on the tarsomeres, a trait also present in Leptocorynus aspersus (Champion) and L. scutatus (Champion) . The subvittate, hirsute vestiture supports the identification of O. subvittatus at least in the material studied, but may be sexually dimorphic as in O. latiscapus and O. salebrosus . Females of this complex are difficult to identify in general, and information about female O. subvittatus is unavailable at present.

Distribution. Central and southern Mexico, localities in Transverse Volcanic Belt and Sierra Madre del Sur ( Fig. 38 ).

Type locality. Mexico .

Material examined. MEXICO: Guerrero ( USNM 1 ) , Michoacán ( CWOB 2 ) , Oaxaca ( JPPC 2 , TAMU 3 ). Total 8 specimens .

Temporal occurrence. Mid July to mid August [3 dates].

Plant association. None recorded.
