Trichoxys Chevrolat, 1860

Trichoxys Chevrolat, 1860: 454; Thomson, 1861: 219; Lacordaire 1869: 63; Lingafelter and Wappes 2012: 155.

Trichoxys was described by Chevrolat (1860) as a subgenus of Clytus Laicharting, 1784. He included 14 species in the group but did not designate a type species. Later, Thomson (1861) elevated Trichoxys to genus level and designated Clytus (Trichoxys) bilineatus Chevrolat, 1860 as type species. Trichoxys is currently composed of 15 species, all of them recorded for Mexico with five of the species extending their known distribution into Central America (Tavakilian and Chevillotte 2018; Bezark 2019). Recently, Lingafelter and Wappes (2012) provided a diagnosis for the genus as follows: “ Trichoxys Chevrolat is characterized from other Clytini by 1) the abruptly recessed parasutural region of the elytron that starts at the anterior one-third and diverges more widely to the apex where it is approximately one-third of the discal width, and the strongly elevated anterior portion of the mesosternum (appearing abruptly recessed from ventral view) and 2) the evenly rounded pronotum that is distinctly narrower than the elytral base and without calli or lateral asymmetry. All the known species have bold, pubescent patterns on the elytra which are easily diagnostic for each species.” They also placed Trichoxys ochraetheoides Linsley, 1935 in synonymy with T. hirtellus (Chevrolat, 1860), described T. penrosei as a new species, and provided a key to the species based on their illustrations of elytral patterns.
