DIVERSITY OF FREE-LIVING TERRESTRIAL NEMATODES (Nematoda: Dorylaimida) AT YOK DON NATIONAL PARK, DAK LAK PROVINCE
v u THI THANH TAM, NGUYEN THI ANH DUONG
SUMMARY
This is the first research on free-living lenestrial nematodes in order Dorylaimida not only in Yok Don National Park, but also for Tay Nguyen area.
The research result has shown that 39 species of Dorylaimida w^ere identified from Yok Don National Park, belong 22 genera, 11 families. In the total of 39 species were identified, 12 species are new records for the Vietnam's fauna, belong 8 genera 6 families (see more detail in the tist of Dorylaimida species, with symbol (*) as a remartt for new recond). Especially, 4 genera such as Paractinolaimus (famiV Actinolaimidae); Dorylaimoides (family Mydonomidae); Eudorylaimus and Microdorylaimus (fami^
Qudsianematidae) are recorded for the first lime for Vietnam's fauna.
In addition. 13 species of free-living tenestrial nematodes in order Dorylaimida were identified in other areas from Vietnam in previous also they were recorded in Yok Don. However, there are still 14 species that were not identified due to not available references.
