Helminths of sympatric populations of kangaroo rats (Dipodomys ordii) and grasshopper mice (Onychomys leucogaster) from the high plains of eastern New Mexico.

During a 1-yr period 124 Dipodomys ordii and 92 Onychomys leucogaster were trapped from the same locality and were examined for helminths. Only 1 cestode species (Catenotaenia linsdalei) was recovered from D. ordii, whereas O. leucogaster was infected with 2 nematoda (Litomosoides carinii, Mastophorus muris), 2 cestoda (Hymenolepis citelli, and 1 unknown), and 1 acanthocephalan (Moniliformis clarki) species. All represent new host and distribution records.
