Campsurus emersoni Traver

Campsurus emersoni Traver 1947: 392 .

Material. Not studied.

Distribution. Panamá.

Diagnosis and discussion. Campsurus emersoni can be separated from the other species of the genus by the following combination of characters: 1) pedestals and penes similar to C. violaceus ( Figs. 1–3 ) except that "thumb" is apparently absent from figure 36 of Traver 1947). This species is most probably another junior synonym of C. violaceus .
