A Re-Description of Progamotaenia Ewersi (Schmidt, 1975) (Cestoda: Anoplocephalidae) from Wallabies and Kangaroos (Macropodidae) with the Description of a New Species, Progamotaenia Ualabati N. SP.

Abstract

A new species of anoplocephalid cestode, Progamotaenia ualabati n. sp., is described from the small intestines of the wallabies Wallabia bicolor (Desmarest, 1804) and Macropus parma Waterhouse, 1845. It most closely resembles P. ewersi (Schmidt, 1975) in having an ovoid cirrus sac which does not extend into the medulla, but differs in strobilar width, the length of the distal vagina, the asymmetry ratio of the female genitalia and the shape of the egg. Progamotaenia ewersi is redescribed from the type host, M. agilis (Gould, 1842). Specimens from this host species differ from those found in M. fuliginosus (Desmarest, 1817) and M. giganteus Shaw, 1790 in scolex size and from specimens from M. parryi Bennett, 1835 in the size of the seminal receptacle. Specimens are also reported from Macropus rufogriseus (Desmarest, 1817), M. irma (Jourdan, 1837), W. bicolor, Petrogale assimilis Ramsay, 1877, Pet. penicillata (Gray, 1825) and from captive M. rufus (Desmarest, 1822) and M. parma. However, insufficient material is available for detailed morphological comparisons. Specimens currently identified as P. ewersi from M. robustus Gould, 1841 represent an undescribed species.
