Lf. Skerratt, STRONGYLOIDES-SPEAREI N-SP (NEMATODA, STRONGYLOIDIDAE) FROM THE COMMON WOMBAT VOMBATUS-URSINUS (MARSUPIALIA, VOMBATIDAE), Systematic parasitology, 32(2), 1995, pp. 81-89
Strongyloides spearei n. sp. is described from the small intestine of
the common wombat Vombatus ursinus from Healesville, Victoria. The new
species is distinguished from all known congeners by: the triangular
shape of the stoma and the length of the parasitic female; the blunt s
picules in the free-living male; and the presence of eggs in the faece
s of the host. S. spearei and S. thylacis Mackerras, 1959 form a separ
ate group within Strongyloides based on both species infecting marsupi
als, having directly recurrent ovaries in the parasitic female and hav
ing blunt-spicules in the free-living male. The histological localisat
ion of S. spearei is predominantly within the crypts of the small inte
stine.
