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).
