Phenacogaster suborbitalis Ahl, 1936

Phenacogaster suborbitalis Ahl, 1936:24 . Type locality: Ostküste Brasiliens. [ Brazil]. Holotype: ZMB 20806. [Figure of the holotype in Zarske, Géry (1995, fig. 12)].

Distribution: 323 (H. J. Paepke, pers. comm.).

Remarks: Phenacogaster suborbitalis was described from a specimen donated by Johannes Paul Arnold. According to correspondences sent by Hans-Joachim Paepke (former curator of the fish collection of the Museum für Naturkunde Berlin), Arnold was a great German aquarium hobbyist and received the specimen from an importer, but both the importer and the precise locality of the specimen are unknown. Hans-Joachim Paepke further informed that Arthur Rachow, in a report titled “ Phenacogaster suborbitalis E. Ahl ”, mentioned the locality of the species as Eastern Brazil, in small coastal-streams between the states of Pernambuco and Maceió, but Rachow did not provide the source of the information. Until now, no species of Phenacogaster was found in the area mentioned by Rachow. Two species could be considered as occurring in the “east coast of Brazil ”, P. calverti from coastal rivers in the northeast and P. franciscoensis from Rio São Francisco and Rio Paraguaçu basins. However, they differ from the holotype of P. suborbitalis in several characters. Specimens similar to the holotype of P. suborbitalis were found in northern Brazil (Rio Guamá drainage) and based on that Lucena et al. (2007) cited the distribution of the species in streams near the city of Belém, Pará State.

Phenacogaster tegatus (Eigenmann, 1911)

Vesicatrus tegatus Eigenmann, 1911c:174 , Pl. 7 (fig. 1). Type locality: Jaurú , Upper Paraguay basin. [ Brazil]. Holotype: FMNH 54573 . [The holotype was considered missing (Ibarra, Stewart, 1987) until the examination of photos of five paratypes ( FMNH 54573 ) from Jaurú, sent by Kevin Swagel in October 24, 2022, which allowed the identification of the holotype among them. This specimen has the peculiar contour of the humeral spot, which is identical to the illustration in Eigenmann, 1911c (plate 7, fig.1) and was reproduced in Eigenmann, 1921(plate 52, fig. 4), and it also presents a half-open mouth, like in the figure. The four remaining type-specimens were cataloged as FMNH 148667 . For other comments see Lucena, Malabarba, 2010].
