    Morphology of the synlophe and genital cone of Parostertagia heterospiculum (Trichostrongylidae) with comments on the subfamilial placement of the genus (1992)

    Notes: Abstract The genus Parostertagia is referred to the Cooperiinae with reference to a suite of shared characters of the synlophe and genital cone postulated as derived homologies for the subfamily. The genus has traditionally been relegated to the Graphidiinae or Ostertagiinae, but unique structural attributes of the synlophe and genital cone indicate close affinities with the Cooperiinae. The synlophe of Parostertagia heterospiculum is characterised by a relatively low number of ridges in the cervical zone (16–20 at the excretory pore), a frontal axis of orientation, sequential increase in ridges posteriorly, lateral addition of ridges, minuscule lateral-most ridges and hypertrophy of specific ridges in the lateral field of females. The genital cone with a tripartite “0” papilla, a pair of dorsal cloacal papillae (a character potentially homologous with lateral protuberances in some cooperiines, but reported for the first time in this study), and paired “7” papillae supporting a small accessory bursal membrane appear unique among the trichostrongylids. Additionally, Parostertagia was found to possess minuscule cervical papillae and a rudimentary (or reduced?) cephalic and cervical expansion. Inclusion of Parostertagia within the Cooperiinae is based on shared characters with this subfamily (postulated synapomorphies) rather than differences that may be utilized to separate this genus from members of other subfamilies of the Trichostrongylidae.

    Comparative morphology of Ostertagia mossi and Ostertagia dikmansi (trichostrongylidae) from Odocoileus virginianus and comments on other Ostertagia spp. from the Cervidae (1993)

    Notes: Abstract The synlophes of Ostertagia mossi Dikmans, 1931 and O. dikmansi Becklund & Walker, 1968 were found to be identical supporting recognition of these as the major and minor morphotypes, respectively, of a putative species pair within the Ostertagiinae. The cervical synlophe included three narrowly spaced, continuous, parallel ridges laterally and three parallel but more widely spaced ridges in the dorsal and ventral fields (Type II and Type A patterns, respectively). The disposition of the synlophe in conjunction with a long oesophageo-intestinal valve, and attributes of the genital cone and spicules are characteristics shared among other Ostertagia spp. from cervids in the Holarctic region that allow recognition of a species group morphologically distinct from the Ostertagiinae of domestic ruminants. The morphological similarity of O. mossi/O. dikmansi, O. leptospicularis Assadov, 1953/O. kolchida Popova, 1937 and O. gruehneri Skrjabin, 1929/O. arctica Mitzkewitsch, 1929 is substantial, but these species can be differentiated by small but constant differences in the synlophe and genital complex of males; females cannot be easily distinguished. The morphological similarity of this cryptic complex of species and their relatively restricted distribution among cervids suggests a coevolutionary history for hosts and parasites in the Holarctic region.

    Alcataenia atlantiensis n. sp. (Dilepididae) from the razorbill (Alca torda Linnaeus) in the eastern North Atlantic basin (1991)

    Notes: Abstract A new species of Alcataenia is described from razorbills Alca torda Linnaeus from the southern region of the North Sea in the coastal waters of Belgium. It differs from known species of the genus in having 18–20 rostellar hooks measuring 63–74 μm in length. Other attributes include a cirrus-sac 145–228 μm in length, 36–49 testes and a vitelline gland measuring 114–202 × 59–112 μm. This is the first species of Alcataenia described from razorbills and appears to be the only member of the genus which is endemic to the North Atlantic basin.

    A comparison of cuticular ridge patterns and other morphological characters of Mazamastrongylus odocoilei and Mazamastrongylus pursglovei (Nematoda: Trichostrongyloidea) from white-tailed deer Odocoileus virginianus (1993)

    Notes: Abstract 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.
