Matheus Vieira Volcan, Luis Esteban Krause Lanés and Ândrio Cardozo Gonçalves: Austrolebias bagual, a new species of annual fish (Cyprinodontiformes: Rivulidae) from southern Brazil, pp. 161-172

Abstract

Austrolebias bagual, a new species of annual fish closely related to the A. adloffi species group, is described from specimens collected from temporary ponds located in the middle course of the Rio Camaquã, Laguna dos Patos system at the municipality of Encruzilhada do Sul, Rio Grande do Sul, Brazil. The new species is distinguished from other Austrolebias species by the unique male pigmentation pattern of the dorsal fin, with black vertical bars elongated from the base to the medial portion of the fin, and by the pattern of transversal black bars on the body, which become gradually shorter and fainter towards caudal peduncle. It is also distinguished from all species of the A. adloffi species group by the lower body depth and head (except in A. rei­cherti), lower anal fin base length and caudal fin length in males, and the lower head depth (except in A. reicherti) and anal fin base length in females. In addition, A. bagual females do not have the pair of black spots arranged vertically in close proximity on the posterior portion of caudal peduncle typical of most species of the A. adloffi group.

William D. Anderson, Jr.: The plates in Holbrook’s Ichthyology of South Carolina, 1860, pp. 173-218

Abstract

Best known for North American Herpetology, John Edwards Holbrook (1794-1871) also published several ichthyological works, the most important of which was his Ichthyology of South Carolina (1855b, 1860). Because of their rarity, reproductions of the plates from the 1860 edition are presented herein, along with comments on the fishes illustrated, Holbrook’s artists, his other ichthyological work, and his herpetological contributions. In order to put his efforts in perspective, I also include a biographical sketch of Holbrook.
