“…Wolfgang (1951) and Crites (1956) also described this single papilla in C. cameroni Wolfgan 1951and C. Americana Maplestone, 1930, respectively. As Travassos (1917, 1922, these authors did not describe deirids in C. tentaculata. In the present study, the morphological analyzes by light microscopy and SEM allowed the identification of the nematode parasite of the large intestine from D. marsupialis from Colombia and D. aurita from Brazil as C. tentaculata.…”

“…Travassos (1917) created the genus for this species naming it C. tentaculata (Rud., 1819), Travassos, 1917, whose main characters were the presence of an intestinal diverticulum projected toward anterior region and three columns of teeth-like structures lining the buccal capsule; later, he added other taxonomic characters to this species as: two pairs of papillae in each oral lip, nine pairs of male caudal papillae (Travassos 1922). Specimens of C. tentaculata Fig.…”

Further description of Cruzia tentaculata (Rudolphi, 1819) Travassos, 1917 (Nematoda: Cruzidae) by light and scanning electron microscopy

Species of Cruzia are parasites of the large intestine of marsupials, reptiles, amphibians, and mammalians. Cruzia tentaculata specimens were collected from the large intestine of Didelphis marsupialis (Mammalia: Didelphidae) from Colombia (new geographical record) and from Brazil and analyzed by light and scanning electron microscopy. The morphology of males and females by light microscopy corroborated most of the previous description and the ultrastructure by scanning electron microscopy evidence: the topography of the cuticle, deirids, amphids, phasmids in both sexes, a pair of papillae near the vulva opening, and the number and location of male caudal papillae, adding new features for species identification only observed by this technique.

“…The species of the genus Cruzia in which the set of morphological and morphometric characteristics is closest to those of Cruzia lauroi sp. nov. is C. tentaculata (Rudolphi, 1819) (Table 1), which occurs mainly in mammals of the family Didelphidae (Travassos, 1917(Travassos, , 1922Ruiz, 1947;Adnet et al, 2009). The latter species has also been recorded in Tupinambis teguixin (Linnaeus, 1758) (Squamata; Teiidae), and Rhinella marina (Linnaeus, 1758) (Anura; Bufonidae) (Ruiz, 1947).…”

Cruzia lauroi sp. nov. is described from Salvator merianae (Duméril & Bibron, 1839) (Squamata; Teiidae). The new species differs from all previously described species through several morphological characteristics: number of tooth like structures per row in the inner pharynx; and presence of unpaired papillae on the anterior border of the cloacal aperture. However, Cruzia lauroi sp. nov. is closest to C. tentaculata (Rudolphi, 1819), through having similar distribution of male caudal papillae, unpaired pre-cloacal papillae and females with an pre-equatorial vulva. Cruzia lauroi sp. nov. differs from C. tentaculata regarding smaller total body length of individuals, higher number of tooth like structures per row in the pharynx, greater size of diverticulum, smaller size of spicules and a more anterior vulva than in C. tentaculata; and the males do not have caudal alae. Cruzia mazza, C. travassosia, C. mexicana and C. testudines were considered to be species inquirendae, because their descriptions need more detailed taxonomic studies.

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.
