Diagnosis. See above under the generic information.

Description. Paxillobitoma clinei is the only member of this genus and is diagnosed and characterized by the diagnostic features given in the generic description above. Likely species level diagnostic features may include the pronotal and elytral carination ( Fig. 18 ), coloration, and shape of the male genitalia ( Fig. 3k, l ).

Distribution. French Guiana ( Fig. 21 ).

Biology. Seven specimens were taken at a mercury vapor light; three from Eschweilera pseudodecolorans Mori and one from E schweilera wachenheimii (Benoist) Sandwith (Lecythidaceae) .

Etymology. Named after Dr. Andrew Cline, a fellow Coleopterist and friend who first brought the specimens to our attention.
