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.
