Explanation of Names
Latin anomala 'irregular, deviant'
48 spp. in our area(4)
, 180 in the New World; a huge group, with >1,000 described species worldwide (some of questionable validity)(5)
Some characteristics of the genus:
small to medium-sized, slightly oval-shaped, convex in cross-section
antennae with 9 segments
pronotum not pubescent (hairy)
elytra with shallow striations and punctures, rather translucent (membranous) along sides
Mesosternum between mesocoxae concave to flat anteriorly, not elevated posteriorly to more than low umbo ......... top, most spp.
Mesocoxae separated by distinctly convex to prominently raised mesosternal process, sometimes porrect ...... bottom, includes spp. such as A. marginata, lucicola & oblivia
[These were placed in the genus Pachystethus
in much of the older American literature and Callistethus
was used in combination with marginata

Casey, 1915 - e. US to s. Calif. / Mex. to Columbia - Map (3)
Casey (1915) divided the genus Anomala
into 3 groups with subgenus status. He called the first Paranomala
and included most of the species studied in it. That name was synonymized by Machatschke (1957) with Anomala
