Systematic status of Thominx platyrrhinorum Barus, 1961 (Nematoda: Capillariidae).
A reexamination of the type specimens of Thominx platyrrhinorum Barus, 1961, described from the small intestine of the monkey Cebus capucinus from a zoo in Czechoslovakia, has revealed that it belongs to the genus Aonchotheca López-Neyra, 1947. The minute refractile formations on the surface of the proximal part of the spicular sheath, originally described as spines in this species, are also present in Aonchotheca annulosa parasitizing murid rodents. Since there are no substantial morphological or biometrical differences between these two species, as indicated by the description of A. annulosa specimens originating from Apodemus sp. from Czechoslovakia, T. platyrrhinorum is considered to be a synonym of A. annulosa (Dujardin, 1845). Another synonym of the latter is the species originally described as Thominx sadovskoi (sic) (= sadovskajae) Morozov in Skryabin et al. 1957. Armocapillaria Gagarin et Nazarova, 1966, earlier considered a synonym of Pterothominx Freitas, 1959, is now reerected as a subgenus of Aonchotheca López-Neyra, 1947. Armocapillaria moschiferi and Capillaria brochieri are transferred to Aonchotheca as A. (A.) moschiferi (Gagarin et Nazarova, 1966) comb. n. and A. (A.) brochieri (Justine, 1988) comb. n.
