The first report of new species: Trichuris landak

Objective: To study nematode parasites morphology of Hystrix javanica, both through the feces and internal organs. Methods: Feces were observed by direct smear method, internal organ were observed after dissecting the host. Specimens for light microscopy examination were fixed with warm 70 persen alcohol, cleared and mounted in lactophenol for wet mounting. Specimens for SEM examination were postfixed in caccodylate buffer and glutaraldehyde, dehydrated through a graded series of alcohol and freeze dried. The specimens were attached to stubs with double cello-tape, coated with gold and observed with a JSM5310 LV Electron Microscope. Figures 1-14 were made with the aid of a drawing tube attached to Olympus compound microscope, other figures were photograph of Scanning Electron Microscope images . Measurements were given in micrometers as the mean followed by the range in parentheses, unless otherwise stated. Results: The nematode species found in the intestine of H. javanica are Gireterakis girardi and a new species, Trihuris landak. The new species differs with previously reported species from Hystrix because of having stylet and short cervical alae. The pattern of bacillary band is closed to T. trichiurus, the species that infect human, but differs because of the surface of its vulva not covered with densely spine. Conclusions: The species of nematodes find on Hystrix javanica are Gireterakis girardi and a new species Trichuris landak n.sp. Those two species are the new record in Indonesia.
