title: Tinaminyssus juxtamelloi sp. n. (Acari: Dermanyssidae; Rhinonyssinae) from the nasal passages of the band-tailed pigeon, Columba fasciata, in New Mexico.
abstract: Tinaminyssus juxtamelloi sp. n. is described from the nasal passages of Columba fasciata in New Mexico. The new species is most similar to Tinaminyssus melloi (Castro) 1948 and T. turturi (Fain) 1962, but differs in (1) possessing only 5 pairs of ventral opisthosomal setae, (2) presence of 3 pairs of enlarged setae on the dorsal opisthosoma at the posterolateral margin of the podosomal plate (1 pair) and at the lateral margins of the opisthosomal plate (2 pairs), (3) elongate shape and larger size of the poststigmatic plates, and (4) chaetotaxy and solenidiotaxy of the legs, especially tarsus I with a cluster of 4 solenida and 1 club-shaped solenidion on the apex of the dorsum. The relationships of this with allied species of the genus Tinaminyssus from columbiform birds are briefly discussed.
