Type material. Holotype female from PANAMA, Panama: 8-13 km N El Llano , 20.V.1987, F.T. Hovore leg. (TAMU, formerly DHCO).

Etymology. The new species is dedicated to the late Frank Hovore, colleague of both authors and collector of the holotype.

Remarks. The general appearance of Oedopeza hovorei sp. nov. is very similar to that of Paralcidion bilineatum Gilmour, 1957 ( Figs 26–30 ). We have seen photographs of specimens from Panama identified as P. bilineatum that, at least in dorsal view, appear to be O. hovorei sp. nov. However, P. bilineatum has the humeral carina well marked ( Figs 26, 29 ) from humeri to near apex, while the humeral carina is slightly distinct only basally in O. hovorei sp. nov., and there is another longitudinal carina ( Fig. 29 ) between humeral carina and epipleural margin (absent in O. hovorei sp. nov.). In fact, the presence of the well-marked humeral carina and of the longitudinal lateral carina in Paralcidion Gilmour, 1957 are the only features that allow it to be separated from Oedopeza . According to Gilmour (1957) on Paralcidion : “Allied to Alcidion Thomson in many characters, but differing in having the pronotal disc distinctly tuberculate, in having elytral setae and the prosternal protuberance very narrow.” However, the species of Alcidion also have elytral setae and the prosternal protuberance [prosternal process] is also narrow in the type species of Alcidion , A. humeralis (Perty, 1832) .

Oedopeza hovorei sp. nov. is similar to O. leucostigma ( Figs 16–20 ) and O. raberi sp. nov. ( Figs 8–15 ) but differs especially by the dense semicircle-shaped yellow pubescent macula close to suture on the posterior quarter of elytra (absent in O. leucostigma and O. raberi sp. nov.). It also differs from O. raberi by the absence of dense yellow pubescent maculae on the metaventrite and abdominal ventrites (present in O. raberi sp. nov.).

The holotype was one of several Panamanian cerambycids gifted to the first author during a visit to Hovore’s home in 1996.
