Dimensions (mm) (holotype male/ paratypes female).

Type material. Holotype male from PANAMA, Bocas del Toro: Fortuna Cabins, 08.7814ºN 82.1909ºW, MV/UV, 27.IV-4.V.2023, B.T. Raber leg. (TAMU, formerly DHCO). Paratypes — 1 female, same data as holotype (DHCO); 2 females, same data as holotype, except UV light, 23-30.V.2022, E.G. Riley leg. (MZSP; DHCO).
Etymology. The new species is dedicated to Brian Raber, friend of the first author and collector of the holotype.
Remarks. Oedopeza raberi sp. nov. is similar to O. leucostigma Bates, 1864 (Figs. 16–20), but differs: posterior quarter of elytra with oblique, uniform white pubescent band reaching suture in both sexes (Figs 8, 14); protibiae with abundant, long setae laterally in male (Fig. 11); protibiae in male with distinct, elongate carina on apical region of ventral surface (Figs 12–13); and protarsomeres in male with abundant, long setae laterally (Fig. 8). In O. leucostigma, the white pubescent band on the posterior quarter of elytra is irregular, often almost transverse, and does not reach the suture in both sexes (Figs 16, 20), protibiae in male have sparse and moderately short setae laterally (Fig. 16) and the ventral carina is short and slightly distinct (Fig. 19), and the protarsomeres in male have no abundant and long setae laterally (Fig. 16). We have seen photographs of O. raberi sp. nov. identified as O. leucostigma (in the former collection of Frank T. Hovore, now deposited at CASC).
