Explanation of Names
Cupedidae Laporte 1836
37 species in 8 genera worldwide; 4 genera, with one species each, in our area:(1)(2)
Cupes capitatus e. NA
Tenomerga cinereus e. NA
Priacma serrata w. NA
Prolixocupes lobiceps so. AZ, CA

Additionally, Tenomerga mucidae is known from Hawaii and Paracupes mexicanus is known from southern Mexico. (2)
These beetles have a flattened parallel-sided body, large closely placed elytral punctures, and broad scale-like setae.

Key to genera/species in American Beetles (pg. 20). (1)
Larvae are known to live in fungal-infested wood. Adults may found associated with the larval habitat, and they are sometimes attracted to lights. Adults may also be collected in traps designed to catch wood-boring insects (e.g. Lindgren funnel traps).
The larvae devour the eggshells populating their intestines with the same microbes as their mothers.(3)
Extinct species outnumber extant species worldwide.(4)
Adults will come to lights.(4)
Male beetles are enticed by the odor of laundry bleach. Females must emit a pheromone that smells like this.(4)
