Vol. 85, Nos. 7 & 8, July & October 1974 22 1 BATFLIES (STREBLIDAE AND NYCTERIBIIDAE) IN THE EASTERN UNITED STATES, AND A NYCTERIBIID RECORD FROM SASKATCHEWAN 1 John O. Whitaker, Jr., 2 David A. Easterla 3 ABSTRACT: Batflies (Streblidae and Nycteribiidae) are uncommon on bats of the eastern United States, east of Kansas, Oklahoma and Texas, but two species of streblids and three of nycteribiids have been reported from this area. The streblids are Trichobius corynorhini from Plecotus townsendii and P. rafinesquii and T. major from Myotis austroriparius.. The nycteribiids are Basilia boardmani from Myotis austroriparius and A/. lucifugus, and B. forcipata and B. antrozoi from Tadarida brasiliensis. DESCRIPTORS: Batflies of eastern U.S. bats There are a number of records of streblid and nycteribiid flies on bats from Central and South America and in the western United States from Texas, Oklahoma and Kansas westward. There are few records east of these states. The purpose of this paper is to summarize records of Streblidae and Nycteribiidae of the eastern states and to present new state and host records for Trichobius corynorhini. Two species of Streblidae and three of Nycteribiidae are known from the eastern United States as follows. STREBLIDAE Trichobius corynorhini Cockerell, 1910: T. corynorhini has been reported from West Virginia by Wilson (1946), Whitaker (1957) and Handley (1959), and from Arkansas by Sealander and Young (1955). Handley (1959) reported T. corynorhini on P. townsendii. but the other three reports cited P. rafinesquii as the host. However, the genus Plecotus Accepted for publication: May 5, 1974 Professor of Life Sciences, Indiana State University, Terre Haute, Ind.. 47809 Dep't of Biology, Northwest Missouri Univ., Maryville, Missouri, 64468 ENT.
