MORSE, GEOFFREY E. & RIBEIRO-COSTA, CIBELE STRAMARE, 2024, New and Confirmed Combinations of New World Bruchinae (Coleoptera: Chrysomelidae) with a List of incertae sedis Species, Zootaxa 5543 (1), pp. 57-82 : 74

Acanthoscelides x-signatus (Pic, 1938). Combination confirmed. Spelling emendation.

Bruchus xsignatus Pic, 1938c: p. 25 . From labels: “Bresil / Nova Friburg / ( Bresil)” [ Brazil]. Female syntype deposited in the MNHN. There is a “ Holotype ” label affixed to this specimen by J.M. Kingsolver. However, the original publication does not designate a holotype nor does it indicate the number of specimens examined. Because no lectotype has been published, this must therefore be considered a syntype. Pic (1938c) publishes this without a hyphen, but includes the hyphen on the specimen label. Because the “x” explicitly refers to an appearance of the specimen (“Jolie espèce, à dessins noirs particuliers des élytres formant, étendus sur la suture et les extrémités, une sorte d'x” = “Pretty species, with particular black patterns on the elytra forming, extended over the suture and the extremities, a sort of x”), and Pic clearly indicates the spelling x-signatus on the label, the spelling is emended to x-signatus in accordance with Article 32.5.2.4.3 of the ICZN (1999). All subsequent publications have used this spelling.
