The Taphrocerus is characterized by small size (typically 3-5 mm), metallic coloration, and compact body form. Definitive identification requires examination of antennal structure, prosternal shape, and elytral microsculpture. The species is most similar to T. chevrolati and T. leoni, from which it differs in details of the frontal grooves and patterns.
Habitat
Moist near water sources, particularly areas with sedges (Carex spp.) and mixed emergent vegetation. have been collected by sweeping grasses and sedges along creek beds and in riparian zones.
Distribution
Middle America and North America. Specific collection records include the southwestern United States (Arizona, New Mexico) and adjacent Mexican states. The has been documented from montane riparian areas in the Chiricahua and Huachuca Mountains of southeastern Arizona.
Seasonality
active in late spring through early summer. Collection records indicate peak activity in May and June, with specimens taken at elevations ranging from approximately 1,500 to 2,000 meters.
Behavior
are and have been observed flying to vegetation near water sources. They are readily collected by sweeping patches of sedges and mixed grasses. Adults may be found in company with , including T. chevrolati and T. leoni, in suitable patches.
