We found that male beetles fly upwind in a zigzag manner, or face upwind when perching, behavior consistent with an animal that is tracking scent. Furthermore, the ultrastructure of the male and female antennae, like their gross morphology, is sexually dimorphic, with male antennae possessing many more of a particular type of receptor-the sensillum placodeum-than their female counterparts (approximately 30,000 vs.

Data on the original combination, current name, and type locality are verified and presented. There are 39 primary types of Onciderini including 11 in Oncideres Lacordaire, 1830; and three each in Hesycha Fairmaire & Germain, 1859; Hypselomus Perty, 1832; Lamia Fabricius, 1775; and Tybalmia Thomson, 1868.
