Dasyrhynchus pacificus Robinson, 1965 (Trypanorhyncha: Dasyrhynchidae) description of the adult form

Abstract

One out of four specimens of sharks, Carcharhinus brachyurus (Günther, 1860), captured off the southern Brazilian Coast, harboured cestodes identified as Dasyrhynchus pacificus Robinson, 1965, of which the adult form is now described and referred as ocurring in Brazil.

A revision of Dasyrhynchus Pintner (Cestoda: Trypanorhyncha), parasitic in elasmobranch and teleost fishes

“…15-19. (host: Sciaena antarctica Castelnau, 1872; Escalante & Carvajal, 1984, p. 191 (host: Sciaena deliciosa (Tschudi, 1844); Sao Clemente & Gomes (1989) …”

“…Until recently, D. pacificus Robinson, 1965 was known only from the plerocercus. Sao Clemente & Gomes (1989) however described the adult cestode from Carcharhinus brachyurus from Brazil. D. variouncinatus was described very briefly from an unknown species shark from Pacific waters off New Guinea (Pintner, 1913).…”

Nematodes of elasmobranch fishes from the southern coast of Brazil

“…In Brazil, the only reports on parasites of these hosts are related to the cestodes of the orders Tetraphyllidea and Trypanorhyncha (Rego et al 1974, Rego 1977, São Clemente & Gomes 1989a,b, 1992, São Clemente et al 1991 and to the anisakid nematodes, represented by two species: Terranova trichiuri Chandler, 1935 andT. rochalimai (Pereira, 1935) Johnston and Mawson, 1945(Vicente et al 1985, Vicente & Pinto 1999.…”

Eutetrarhynchid trypanorhynchs (Cestoda) from elasmobranchs off Argentina, including the description of Dollfusiella taminii sp. n. and Parachristianella damiani sp. n., and amended description of Dollfusiella vooremi (São Clemente et Gomes, 1989)

“…However, no eutetrarhynchids have yet been reported from these hosts in the southwestern Atlantic. Instead, they have been reported as hosts for tentaculariids and lacistorhynchids off Brazil (São Clemente and Gomes 1989b, Knoff et al 2002, Gomes et al 2005.…”
