“…These characters confirm the synonymy of Mazamastrongylus and Spiculopteroides as previously established (see Jansen, 1986; contrary to Gibbons and Khalil, 1982). In contrast, Spiculopteragia is characterized by ventral rays that are not parallel, but converge distally, and a ray 4 that is substantially shorter than ray 5 (Hinaidy and Prosl, 1981;Durette-Desset, 1983;Jansen, 1986).…”

“…In Mazamastrongylus, the bursa has parallel and slightly divergent ventral rays (rays 2 and 3) and the antero-and mediolateral rays (4 and 5) are of near equal length with slightly divergent tips (Jansen, 1986). These characters confirm the synonymy of Mazamastrongylus and Spiculopteroides as previously established (see Jansen, 1986; contrary to Gibbons and Khalil, 1982).…”

“…The genital cone and particularly the structure of the accessory bursal membrane and "7" papillae (Fig. 4) is consistent with those described for M. trinitatis and other species of the genus (Jansen, 1986;Lichtenfels et al, 1993). The ovoid accessory bursal membrane is only slightly cuticularized and is supported by slender and divergent "7" papillae; lateral processes were present at the margin of the cloaca.…”

“…In agreement with Jansen (1986Jansen ( , 1989, characters of the bursa, genital cone, and spicules are consistent with placement of M. peruvianus in Mazamastrongylus. Additionally, the unique tapering pattern and hood ridges appear typical for species of Mazamastrongylus and are highly distinct when compared to cervical synlophes characteristic of Ostertagia and Teladorsagia (Lichtenfels and Pilitt, 1991; Lichtenfels et al, 1993).…”

A comparison of cuticular ridge patterns and other morphological characters of Mazamastrongylus odocoilei and Mazamastrongylus pursglovei (Nematoda: Trichostrongyloidea) from white-tailed deer Odocoileus virginianus

et al. 1993

The synlophes of Mazamastrongylus odocoilei (Dikmans, 1931) and M. pursglovei (Davidson & Prestwood, 1979) from Odocoileus virginianus were described to provide characteristics for their differentiation from related species in domestic and wild ruminants. The synlophes of M. odocoilei and M. pursglovei were identical. Both had single continuous dorsal, ventral and lateral ridges. Other ridges in the lateral fields in the anterior third of the body angled posteriorly ending adjacent to the single lateral ridge. The ridge system in Mazamastrongylus spp. appears to be unique in lacking the continuous subventral and subdorsal ridges present in all previously studied medium stomach worms from domestic ruminants. Only two characters, spicule length and structure, are known to be useful for differentiating males of M. odocoilei and M. pursglovei, and females cannot be differentiated. Evidence that M. odocoilei and M. pursglovei are separate species include: (1) the two species are frequently found together in the same individual host, but each is also found in the absence of the other; (2) no overlap in spicule size or intergrades in shape have been found although numerous populations have been sampled; and (3) the two species have overlapping, but different, geographical ranges in eastern North America. No differences in the synlophe were found between these two species. The importance of this finding is that the absence of differences in the synlophe is not an unequivocal indicator that nematodes are conspecific.

A list of 19 polymorphic species of the genera Ostertagia, Orloffia, Teladorsagia, Marshallagia and Spiculopteragia is presented. The morphs of the polymorphic species in question have identical females and show similarities in some male features, e.g. the structure of the oesophagus, the synlophe and the shape of the rays of the copulatory bursa. However, they differ by characters which are recognised as generic features, e.g. the structure of spicules, gubernaculum and genital cone. The presence or lack of minor morphs is a generic feature in the Ostertagiinae. Each polymorphic genus has a defined type of minor morph.
