Two new nematode species of Bunomystrongylus n. gen. (Trichostrongylina:Heligmonellidae) collected from Bunomys spp. (Rodentia:Muridae) of Sulawesi, Indonesia.
Bunomystrongylus n. gen. (Nematoda: Heligmosomoidea: Heligmonellidae: Nippostrongylinae) was proposed, and 2 new species, Bunomystrongylus abadii n. sp., the genotype, from Bunomys penitus and Bunomystrongylus miyagii n. sp. from Bunomys andrewsi, both collected in Sulawesi, Indonesia, were described. This genus is distinguished from other genera of Nippostrongylinae by the peculiar synlophe having round ridges without intracuticular supports on dorsal to left lateral fields in midbody, the extremely long filiform spicules, and the complexly coiled vestibule. Bunomystrongylus abadii differs from B. miyagii by having the right lobe of the bursa copulatrix larger than the left lobe, smaller length ratio of the spicules to body length, and a dorsal ray divided more distally. Bunomystrongylus is presumed to have derived from a common ancestor with Rattustrongylus and Hasanuddinia on the Asian continent and evolved on Sulawesi Island.
