Raillietnema minor Freitas & Dobbin Jr., 1961

Hosts (prevalence; range): P. azureus (26/47; 2–103).

Site of infection: large intestine.

Stage: adult.

Type host and type locality: Pithecopus nordestinus (Caramaschi) (= Phyllomedusa hypochondrialis ), Camaragibe, Pernambuco State, Brazil.

Comments: Travassos (1925) described Oxysomatium simples Travassos in Boana faber in Brazil (Rio de Janeiro and Minas Gerais). However, Travassos (1927) created the genus Raillietnema and its synonymy with Oxysomatium resulting in Raillietnema simples (Travassos) – the type species of the genus (Travassos 1927; Gomes 1966). Since then, several species were described in different regions of the world such as Africa and Madagascar (see Gomes 1966). Currently, there are 24 species, eight in Neotropical Realm, and they have the following main characters: large eggs in reduced number positioned as a rosary (Travasso 1927; Bursey & Goldberg 2006). Our specimens presented the main characters according to the description of Raillietnema minor , such as male tail with four pairs of preanal papillae in traversing grooves, length of spicules and size of female eggs (see Freitas & Dobbin 1961). Besides the type locality, R. minor had only been recorded in Pantanal wetland, Brazil (Campi„ o et al. 2016).
