Two species of hypopial nyrnphs of mites of the family Glycyphagidae were recovered from Heteromys gaumeri from Yucatan, Mexico. Numerous specimens of a hypopus identified as Dermacarus ornatus. Fain were recovered from the hair and skin. A single specimen of an endoparasitic hypopus identified as a new genus and species, Neolabidophorus yucatanensis, was recovered from the hair follicles. The new genus differs from similar forms of the subfamily Metalabidophorinae in having a rudimentary clasper organ represented by a median sclerite behind legs IV without external serrated claspers, structure and slightly dorsal position of the tarsal solenidia on legs I and 11, and a modified pair of subpalposoinal setae on the median venter.
