Remarks: Comparison of the type specimens of these species revealed no remarkable differences between Chrysotus viridis and C. diligens . We herein consider both species synonyms. Moreover, BECKER (1922) ’s description of C. viridis is inaccurate: it refers to a black palpus, which is actually whitish yellow, as mentioned in PARENT’s (1931) description of C. diligens , although in some specimens it is somewhat opaque and misleading depending on light incidence. BECKER (1922) listed 5 males and 25 females in his type series of C. viridis , but only 29 specimens (22 males and 7 females), 7 of them with type red labels, were found. We selected the specimen with both the “typus” and the Becker’s handwritten labels to be the lectotype, although it is not any of the syntypes designated by KALLWEIT and NEGROBOv (1994).
