Description of the adult form of Nybelinia (Syngenes) rougetcampanae Dollfus, 1960 and some new data on n. (n.) bisculata (Linton, 1889) (Trypanorhyncha: Tentaculariidae)

The adult form of Nybelinia (Syngenes) rougetcampanae Dollfus, 1960 is described, parasitizing one specimen of Sphyrna lewni (Griffith & Smith, 1834) out of the five ones necropsied and one out of six Nothorhynchus pectorosus (Garman, 1884) was found harbouring N. (N.) bisculata (Linton, 1889). The finding of these cestodes under Trypanorhyncha in sharks captured off the coast of Rio Grande do Sul State, Brazil, amplifies their known geographical distribution and adds new host records for these parasites.

Description of males of Parabronema pecariae Ivaschkin, 1960 (Nematoda, Habronematoidea) parasitizing peccaries (Mammalia, Tayassuidae) in Brazil

Nematodes studied herein and identified as Parabronema pecariae were collected in 1936 in the States of Rio de Janeiro and Pará and in 1940 in the State of Mato Grosso do Sul, Brazil. This species was proposed, with basis on female specimens that had been described earlier as Parabronema sp. Although the presence of males of P. pecariae was previously reported in Brazil, their description was not provided. The present paper deals with the first complete morphometric data on male specimens of P. pecariae recovered from peccaries (Pecari tajacu and Tayassu pecari).
