Kyphosus sectatrix (Linnaeus 1758)

Extant specimens: MCUC ZOO.0000043 (Fig. 46a) and MCUC ZOO.0000058 (Fig. 46b).

Classification on the specimen: “P. Th. Chaetodon ”.

Common names on the specimen (Portuguese/Tupi): None.

Comments: Both specimens have the specific name “ triostegus ” written in pencil after the genus, which was subsequently crossed out also in pencil. This was probably a subsequent reidentification. Chaetodon triostegus Linnaeus 1758 (= Acanthurus triostegus) is an Indo-Pacific species very different morphologically from Kyphosus sectatrix . There are 24 herborized specimens of Chaetodon mentioned in the Ajuda’s inventory (Ferreira 1794), and while two specimens of Chaetodon triostegus are mentioned in the transference list to Coimbra, we believe that they are in fact specimens of Chaetodipterus faber (see in the comments of this species). Kyphosus sectatrix is a circumglobal species, occurring in tropical and temperate waters (Knudsen & Clements 2013).
