New Record for Camptodes nigerrimus Grouvelle (Coleoptera: Nitidulidae) from Southeastern Arizona
Members of the genus Camptodes Erichson are contained in the tribe Cyllodini of the subfamily Nitidulinae. Species are glabrous and typically oval in shape with various degrees of convexity in profile. Camptodes species are easily recognized by the above characters as well as lobed hind tarsi, bilobed labrum, exposed pygidium, and prosternal process greatly extended posteriorly, often completely covering the mesosternum. The genus contains approximately 175 species and is restricted to the Neotropics from Argentina and Uruguay north to Mexico and the southwestern U.S.
Three species are known to occur in the U.S.; C. texanus Schaeffer, C. gaumeri Sharp, and C. nigerrimus Parsons (see Parsons 1943 for detailed descriptions). The former two are known from southern Texas and the latter from southeastern Arizona. Both C. texanus and C. gaumeri are known to have ranges extending into Mexico, however, C. nigerrimus was previously known only from the type locality in Santa Cruz Co., Arizona. The new record below indicates that C. nigerrimus is distributed through more of southeastern Arizona. This new record indicates an eastward range extension of approximately 100km. Notably, this range extension also demonstrates that this species occurs on two separate mountain ranges in southeast Arizona.
