2 NEW NEMATODE SPECIES OF BUNOMYSFRONGYLUS 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 a badii n. sp. the genotype, from Bunomys penitus and Bunomystrongylus m iyagii n. sp. from Bunomys andrewsi, both collected in Sulawesi, Indon esia, were described. This genus is distinguished from other genera of Nippostrongylinae by the peculiar synlophe having round ridge without intracuticular supports on dorsal to left lateral fields in midbody, the extremely long filiform spicules, and the complexly coiled vestibu le. Bunomystrongylus abodii differs from B. miyagii by having the righ t lobe of the bursa copulatrix larger than the left lobe, smaller leng th 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.
