“…Cruzia tentaculata was reported parasitizing M. myosuros by Travassos (1922) and Thatcher (2006) in Brazil and by Tantaleán et al (2010) in Peru. Viannaia conspicua and V. pusilla were found in this marsupial by Freitas (1937) in Angra dos Reis, state of Rio de Janeiro, Brazil, and the latter was also reported by Thatcher (2006) in Brazil. Lent & Freitas (1937) reported P. mirandai in M. myosuros in Angra dos Reis, Brazil; Barros (2015) found this species in the states of Acre and Bahia, Lopes- Torres et al (2019) in the state of Espírito Santo, Brazil, and Tantaleán et al (2010) in Peru.…”

“…In relation to helminths, all studies published on this host have been reports of species occurrence or species descriptions (Travassos, 1913;Travassos, 1920;Travassos, 1922;Freitas, 1937;Lent & Freitas, 1937;Proença, 1937;Sarmiento, 1954;Vicente, 1966;Travassos et al, 1969;Grisi & Castro, 1974;Gomes, 1979a, b;Noronha et al, 2002;Thatcher, 2006;Tantaleán et al, 2010;Barros, 2015;Lopes-Torres et al, 2019). No studies on the helminth fauna or its community structure in this marsupial have so far been published.…”

Metachirus myosuros is a marsupial species widely distributed in South America. Despite this, there is a lack of knowledge about its helminth parasites and helminth community structure. The aims of this study were to describe the species composition and determine the parasitological parameters of helminth communities of M. myosuros in preserved areas of the Atlantic Forest, Igrapiúna, Bahia state, northeastern Brazil. Parasites were searched from 19 specimens of this marsupial (18 were infected with at least one species), counted and identified. Ten species of helminth parasites were obtained: 7 nematodes, 2 platyhelminths and 1 acanthocephalan. The most abundant species were Aspidodera raillieti, Cruzia tentaculata, Physaloptera mirandai and Viannaia conspicua (Nematoda). These species were also the only dominant ones in the component community. Male hosts had higher prevalence of P. mirandai and greater abundance of V. conspicua. We observed a relationship between host body size and helminth abundance in both male and female hosts, and between host body size and helminth species richness in female hosts. This was the first study to analyze the helminth fauna and helminth community structure of M. myosuros. This was the first report of occurrences of A. raillieti and Didelphonema longispiculata in M. myosuros.

“…The females were unknown. The males differed in considerable detail and their descriptions suggest that they are abnormal specimens : Travassostrongylus quatuor Freitas, 1937, T. quintus Freitas, 1937, and T. sextus Freitas, 1937 The dorsal ray in these individuals is very complex and irregularly divided into several digitations. The externo-dorsal ray is more slender than the others and does not reach the bursal margin.…”

On a Phylogenetic Classification of the Family Trichostrongylidae Leiper of Marsupials, Insectivores and Edentates

Leiper in 1908, created the sub-family Trichostrongylinae in his new family Metastrongylidae, for those small intestinal bursate nematodes without a buccal capsule. It included the genera Trichostrongylus, Haemonchus, Nematodirus, Cooperia and Ostertagia. In 1912, he raised the status of this sub-family to family rank as Trichostrongylidae Leiper, 1912. All the original genera in this family have a double ovarian system in the female; Heligmosomum described by Railliet and Henry in 1909, has a single ovary and in 1914, Travassos created a new sub-family Heligmosominae for this and related species.
