“…The type species of the second taxon was rst described as Enterobius sciuri (Cameron, 1932) from Sciurus carolinensis in Scotland. Later, Kreiss (1944), described as a new species a pinworm parasite collected in Sciurus vulgaris in Switzerland, which ignoring Cameron's work, he also named Enterobius sciuri (sic). Since then "Enterobius sciuri" has been recorded from S. vulgaris, in Switzerland (Hörning, 1963), Czechoslovakia (Erhardova, 1958;Tenora, 1967), France (Quentin and Tenora, 1975;Hugot, 1984a), Britain (Keymer, 1983;Hugot, 1984a), Spain (Rocamora et al, 1978;Hugot and Feliu, 1990), and Ukraine (Sharpilo and Lugovaya, 1984).…”

A morphologically based cladistic analysis of the Enterobiinae, which includes most of the Oxyuridae parasitic in Primates, allows a reevaluation of the Cameron's hypothesis of close coevolution with cospeciation between hosts and parasites. Each of the three genera separated in the Enterobiinae fits with one of the suborders defined in Primates: Lemuricola with the Strepsirhini, Trypanoxyuris with the Platyrrhini, and Enterobius with the Catarrhini. Inside each of the three main groups, the subdivisions observed in the parasite tree also fit with many of the subdivisions generally accepted within the Primate order. These results confirm the subgroups previously described in the subfamily and support Cameron's hypothesis in its aspect of association by descent. Although the classification of the Enterobiinae generally closely underlines the classification of Primates, several discordances also are observed. These are discussed case by case, with use of computed reconstruction scenarios. Given that the occurrences of the same pinworm species as a parasite for several congeneric host species is not the generalized pattern, and given that several occurrences also are observed in which the speciations of the parasites describe a more complex network, Cameron's hypothesis of a slower rhythm of speciation in the parasites can be considered partly refuted. The presence of two genera parasitic on squirrels in a family that contains primarily primate parasites also is discussed. The cladistic analysis does not support close relationships between the squirrel parasites and suggests an early separation from the Enterobiinae for the first (Xeroxyuris), and a tardy host-switching from the Platyrrhini to the squirrels for the second (Rodentoxyuris).

“…Travassos (1920) proposed that species with six branches should be included in a separate genus Hexametra by designating Ascaris hexametra Gedoelst, 1916, from an African chameleon as type species of Hexametra. Baylis (1921Baylis ( , 1936, Yorke & Maplestone (1926), and Yamaguti (1961) did not adopt this proposal, but it has been accepted by Kreis (1944), Skrjabin, Schikhobalova & Mozgovoy (1951), Mozgovoy (1953), Hartwich (1957), Kutzer & Grunberg (1965) and Araujo (1969). The species in Polydelphis and Hexmetra were listed recently by Araujo (1969).…”

The ascaridoid nematodes with more than two uterine branches, which occur in snakes and lizards, are grouped into three genera: (1) Polydelphis (without interlabia, with four uterine branches) containing the type species, P. anoura, occurring in Old World pythons, with P. brachycheilos as a species dubium. (2) Travassosascaris, a new genus with interlabia and with four uterine branches, with type species T. araujoi (new name for P. quadrangularis (Schneider) of Araujo, 1969) occurring in New World rattlesnakes. (3) Hexametra (without interlabia, with six uterine branches) containing species in lizards and snakes. In lizards, H. hexametra (type species), H. applanata, H. angusticaecoides and H. rotundicaudataaxc tentatively differentiated. In snakes, two Hexametra species are tentatively differentiated: (1) H. boddaertii (with three synonyms) in New World pit vipers and colubrids; (2) H. quadricornis (with twenty-two synonyms) in Old World viperids, elapids and colubrids. The morphology, host range, geographical distribution, development and harmful effects of these species are discussed.
