Neodiplostomum spratti n. sp. (Digenea: Diplostomidae) from Antechinus spp. (Marsupialia: Dasyuridae) in Australia, with notes on other diplostomids from Australian mammals

Abstract

Neodiplostomum spratti n. sp. is described from Antechinus stuartii and A. swainsonii (Marsupialia: Dasyuridae). The status of Neodiplostomum minor, N. flabelliformis, N. intermedius, N. sarcophilus, N. diaboli and Pharyngostomoides dasyuri is reviewed. New hosts records for N. intermedius are Rattus lutreolus, R. leucopus, R. rattus (all Rodentia: Muridae) and Dasyurus maculatus (Dasyuridae). The following undescribed species are recorded: Neodiplostomum spp. from Dasyurus maculatus from Victoria, Dasyurus viverrinus from Tasmania, Perameles nasuta (Marsupialia: Peramelidae) from New South Wales, Sminthopsis leucopus (Dasyuridae) from New South Wales, and a diplostomulum from the lung of Perameles nasuta from New South Wales. The validity of Fibricola is reconsidered and it is proposed that it be considered a synonym of Neodiplostomum. The new combinations Neodiplostomum minor (Dubois, 1936), N. sarcophilus (Sandars, 1957) and N. flabelliformis (Pearson & Dubois, 1985) are proposed: all three were previously attributed to Fibricola.
