Type
: “Mex.” (MNHP;
Hespenheide 1979
); of
Agrilus caliginosus
, Tupátaro
,
México
(UNAM); of
Rhaeboscelis texana
, Brownsville
, Texas (USNM,
lectotype
designated by
Bellamy and Nelson 1989
). A photograph of the
type
of
Agrilus caliginosus
Duges
was provided by W.F. Barr and it is unequivocally this species, which is widespread and common in
México
.
Distribution: Common
970 specimens
examined, Texas to
Costa Rica
.
Host: Adults collected on
Sida
spp.
Discussion: This species as interpreted here is rather variable in size, as indicated above, and coloration. Although the typical color is given above, some specimens can have the elytra purple or dark violaceous and the pronotum brighter purple to golden; many specimens are completely black.
