Gamidactylus bryconis sp. n. (COPEPODA, POECILOSTOMATOIDA, VAIGAMIDAE) DAS FOSSAS NASAIS DE PEIXES, Brycon pellegrini HOLLY, 1929 E Β. melanopterus (COPE, 1872) DA AMAZÔNIA BRASILEIRA

Abstract

Gamidactylus bryconis sp. n. (COPEPODA, POECILOSTOMATOIDA, VAIGAMIDAE) DAS FOSSAS NASAIS DE PEIXES,ABSTRACT -Gamidactylus bryconis sp. n. was collected from the nasa) fossae of Brycon pellegrini and B. melanopterus. The new species resembles Gamidactylus jaraquensis in having antennae with moveable spines distally on the third segment and terminal claws, and a pair of strong moveable lateral retrostylets on the first thoracic somite. The new species can be distin guished from its congeners in the size and shape of the retrostylets and in the armature of the legs.

Gamidactylus piranhus sp. nov. (Copepoda, Vaigamidae) from the nasal fossae of serrasalmid fishes from the Três Marias Reservoir, Upper São Francisco River, Minas Gerais State, Brazil

“…Later, Thatcher and Boeger (1984a, b, c) described three other genera and species of this family, namely: Gamidactylus jaraquensis, Gamispatulus schizodontis and Gamispinus diabolicus, respectively. Subsequently, Gamidactylus bryconis was described from Brycon pellegrini Holly, 1929 = B. amazonicus (Spix et Agassiz, 1829) and B. melanopterus (Cope, 1872) by Varella (1995) and Gamidactylus hoplius from Hoplias malabaricus (Bloch, 1794) by Varella and Malta (1996). All of these species were found in the Amazon River Basin.…”
