    Morphology and Anatomy:

    Ref: Baylis, 1930

    A characteristic of genus Nicollina:

    A synlophe with a small number of body ridges is considered a more primitive character within trichostrongyloid genera (Durette-Dusset, 1971)

     

     

    Females:

    • Didelphic
    • Vulva towards posterior end of body.

    Ref: Baylis, 1930

    Males:  

    • Bursa with symmetrical lateral lobes and without a distinct dorsal lobe.
    • Ventro-ventral and latero-ventral rays widely divergent, the former more slender than the latter. Medio-lateral and postero-lateral rays also rather widely divergent, the latter being more slender than the former. Externo-dorsal rays originate independently of the dorsal ray, near its base. Dorsal ray bifurcate at its tip and with a pair of accessory branches.
    • PrebursaI papillze present.
    • Spicules simple proximally, somewhat membranous and divided distally, with one of the terminations barbed or hooked.
    • An accessory piece present.

    Biology and Ecology:

    Relationships within the family Nicollinidae are not well-defined.  In Australia, Durette-Desset and Beveridge (1981) hypothesized that the genus Copemania is probably derived from Nicollina and suggested that dasyurid marsupials had acquired the genus by host switching of nematodes already present in monotremes.
