description: Illustrated Key to Species of Aneflomorpha from the United States
This genus, perhaps more than any other in the United States, is nearly lacking in distinctive external features that allow for easy identification. Specimens need to be clean, relatively fresh without rubbed setae, and mounted well with legs and antennae not obscuring other structures. Even then, this key will not work for every specimen. Due to intraspecific variation, mutations, possible hybrids, or undocumented species, a few specimens will, unfortunately, remain indeterminate. However, for nearly all specimens, this will be the most useful tool since the genus was proposed over 100 years ago.
