Summary: | Recent redescriptions of most members of the Oxyuridae Cobbold, 1864 parasitic in primates revealed that they share following derived characters: sexual dimorphism of lateral alae (single-crested in the males, double-crested in the females); in males a second pair of genital papillae always surrounded by strongly cuticularized rings; in females, uterine tube divided into 2 parts by a cellular wall forming a diaphragm. These characters are interpreted as synapomorphies, providing evidence that these taxa represent a monophyletic group, and we propose to classify them in a new subfamily of the Oxyuridae: the Enterobiinae subfam. nov. The Enterobiinae as recognized herein occurs in both Old World and New World Primates and rodents of the family Sciuridae (tribe Sciurini in the Holarctic region and tribe Xerini in the Ethiopian region). The new subfamily includes the following genera:
Enterobius Leach, 1853;
Colobenterobius Quentin, Betterton & Krishnasamy, 1979;
Rodentoxyuris Quentin & Tenora 1974;
Xeroxyuris Hugot, 1995;
Lemuricola Chabaud & Petter, 1959;
Protenterobius Inglis, 1961;
Madoxyuris Chabaud, Brygoo & Petter, 1965;
Trypanoxyuris Vevers, 1923;
Hapaloxyuris Inglis & Cosgrove, 1965 and
Paraoxyuronema Artigas, 1936. The genus
Paraoxyuronema is revalidated as a subgenus of
Trypanoxyuris due to its very specialized buccal structures. This genus groups all pinworm nematodes specific for primates of the family Atelidae, including:
P. brachytelesi Artigas, 1937 occurring in
Brachyteles arachnoides; P. atelis (Cameron, 1929) occurring in
Ateles spp., and
P. duplicidens (Buckley, 1931) and
P. lagothricis (Buckley, 1931), which are parasites of
Lagothrix spp.
Inglisoxyuris inglisi Chabaud, Petter & Golvan, 1961, included in the monospecific genus
Inglisoxyuris and previously classified as a subgenus of the
Lemuricola, does not share the characters of the new subfamily and, until its precise classification can be considered with more information, it is proposed to refer to this species as an Oxyuridae
sensu lato. A diagnosis and a key of the genera included in the new subfamily are given. |
