Abstract
Nasal mites of the subfamily Speleognathinae were recovered from several species of birds in Texas. New host records include Ophthalmophagus striatus (Crossley) 1952 from Columbigallina passerina, Boydaia clarki Fain 1963 from Callipepla squamata, Boydaia falconis Fain 1956 from Falco sparverius, and Boydaia tyrannus Ford 1959 from Myiarchus cinerascens. Also recovered was Astrida coccyzae Pence 1972 from Coccyzus americanus. Boydaia pheucticola sp. n. from Pheucticus melanocephalus is described. It differs from similar species in the adult female by having the coxal setae formula 2-1-2-0, sensillae clavate but not globose or subglobose, and interior seta on coxa I reduced in size but not vestigial. The larva is differentiated by the modified legs II with one long recurved hooklike claw and a shorter curved claw.
