A New Syphacia Species (Nematoda: Oxyuridae) Collected from Bunomys spp. (Rodentia: Muridae) in Central Sulawesi, Indonesia

Abstract

Syphacia (Syphacia) rifaii sp. n. (Nematoda: Oxyuridae) is described from endemic Bunomys chrysocomus and Bunomys prolatus (Rodentia: Muridae) on Sulawesi Island, Indonesia. The new species is closest morphologically to Syphacia (Syphacia) sulawesiensis , parasitic in Rattus xanthurus from Sulawesi Island, by having large vesicular lateral alae in males, but is readily distinguished by having a smaller body, a round cephalic plate in both sexes, the absence of lateral alae in females, a longer relative distance between excretory pore and vulva, and smaller eggs. Syphacia (S.) rifaii is surmised to be a specific parasite of Bunomys spp. and has evolved from a common ancestor with S. (S.) sulawesiensis on Sulawesi Island.

“…Specimens from Kabubaten Donggala identified as ''Bunomys chrysocomus'' and series from Lore Lindu said to be ''B. prolatus'' were found to be parasitized by the nematode, Syphacia rifaii (Oxyurida, Oxyuridae), which is presumed to infect only species of Bunomys (Dewi and Hasegawa, 2010). The sample of ''B.…”

“…''Bunomys chrysocomus'' and ''Bunomys prolatus'' from Lore Lindu have also been reported as hosts for the nematodes Subulura andersoni (Ascaridida, Subuluridae), Heterakis spumosa (Ascaridida, Ascarididae), and Syphacia muris (5 S. rifaii, see Dewi and Hasegawa, 2010); ''Bunomys chrysocomus'' from Lore Lindu is host to Protospirura muris (Spirurida, Spiruridae) and Trichurus muris (Trichurida, Trichuridae); and ''Bunomys prolatus'' hosts Molinacuaria indonesiensis (Spirurida, Acuariidae) (Purwaningsih and Dewi, 2007). Again, Bunomys prolatus has been found only on Gunung Tambusisi at the western margin of the eastern peninsula and does not occur in Lore Lindu and I suspect the voucher specimens represent B. chrysocomus.…”

“…The nematode, Syphacia rifaii (Oxyuroidea, Oxyuridae), was extracted from host specimens identified as B. prolatus that were collected in Lore Lindu (Dewi and Hasegawa, 2010), but the host rats are likely examples of B. chrysocomus and not B. prolatus.…”

Two new species ofSyphacia(Nematoda: Oxyuridae) in endemic murid rodents from Sulawesi, Indonesia

“…Species of the nematode genus Syphacia Seurat, 1916 occur in the rodent families Cricetidae and Muridae (Hugot, 1988). From the area east of Wallace's line, 15 fully described species have been recorded: S. abertoni Weaver & Smales, 2006, S. australasiensis Smales, 2004, S. boodjamullaensis Weaver & Smales, 2010, S. brevicaudata Weaver & Smales, 2008, S. carnarvonensis Weaver & Smales, 2010, S. coccymyos Smales, 2011, S. darwini Hugot & Quentin, 1985, S. helidonensis Weaver & Smales, 2010, S. longaecauda Smales, 2001, S. lorentzimyos Smales, 2010, S. mamelontenuis Smales, 2010, S. muris (Yamaguti, 1935), S. pseudomyos Weaver & Smales, 2008, S. rifaii Dewi & Hasegawa, 2010, S. sulawesiensis Hasegawa & Tarore, 1996 (Hugot & Quentin, 1985; Hasegawa & Tarore, 1996; Smales, 2001, 2004, 2010, 2011; Weaver & Smales, 2006, 2008, 2010; Dewi & Hasegawa, 2010). All of them are assigned to the subgenus Syphacia Seurat, 1916, but exhibit considerable diversity in morphology.…”

<i>Syphacia </i>(<i>Syphacia</i>) <i>maxomyos</i> sp. n. (Nematoda: Oxyuridae) from <i>Maxomys</i> spp. (Rodentia: Muridae) from Sulawesi and Sumatra, Indonesia

“…Seven species of Syphacia ( Syphacia ) from Indonesia are currently recognized i.e., S. longaecauda Smales, 2001, from Papua; S. sulawesiensis Hasegawa & Tarore, 1996, S. rifaii Dewi & Hasegawa, 2010, S. taeromyos Dewi & Hasegawa, 2014, and S. paruromyos Dewi & Hasegawa, 2014, from Sulawesi; S. semiadii Dewi, Asakawa & Fitriana, 2014, from Halmahera; and Syphacia muris (Yamaguti, 1935), a cosmopolitan species [3,4,5, 10, 17]. Moreover, Syphacia ( Rumbaisyphacia ) kumis Dewi, Hasegawa and Asakawa, 2014 and Syphacia ( Segienamsyphacia ) yuniae Dewi, Hasegawa and Asakawa, 2014 from Sulawesi have also been described under new subgenera [6].…”
