Bothriocroton oudemansi (Neumann, 1910) n. comb. (Acari: Ixodida: Ixodidae), an ectoparasite of the western long-beaked echidna in Papua New Guinea: Redescription of the male and first description of the female and nymph

Specimens of Amblyomma oudemansi (Neumann, 1910) were collected in Papua New Guinea from an endangered monotreme, Zaglossus bruijni (Peters & Doria), the western long-beaked echidna. These ticks were compared morphologically and molecularly with species formerly assigned to Aponomma Neumann, 1899 (now included in Bothriocroton Keirans, King, & Sharrad, 1994 or Amblyomma Koch, 1844), and a phylogeny was generated. Based on our results, we reassign this tick to Bothriocroton, as B. oudemansi (Neumann, 1910) n. comb. Original descriptions are provided for the female and the nymph of this species and the male is redescribed. A revised list of all Bothriocroton records and holdings in the US National Tick Collection is also provided.
