Vol. 94, No. 5, November & December 1983 213 PARAPHROSYLUS PRAEDATOR AND P. NIGRIPENNIS, NEW TO WASHINGTON, WITH NOTES ON THE GENUS (DIPTERA: DOLICHOPODIDAE) ^ Larry D. Corpus-* ABSTRACT: Adult Paraphrosylus praedator (Wheeler), P. nigripennis (Van Duzee), and P. direptor(Van Duzee) were collected from Freshwater Bay, Clallam County, Washington, This represents the first report of P. praedator and P. nigripennis occurring within the state. Habitat preferences of the 3 species are described. Paraphrosylus Becker, originally proposed as a subgenus otAphrosylus Haliday (Becker 1922) later considered a synonym ofAphrosylus (Foote et al., 1965; Cole 1969) is presently considered a valid genus (Robinson and Vockeroth 1981). Paraphrosylus contains 8 species (Van Duzee 1924; Harmston 1951, 195 2) found in the western Nearctic region. Collection of adult Diptera, at low tide, from a beach in Freshwater Bay, 22.5 km west of Port Angeles, Clallam County, Washington on 23 May 1981 yielded 3 species of Paraphrosylus. Six males and 6 female Paraphrosylus praedator (Wheeler), 4 male and 3 female adults of P. nigripennis (Van Duzee), and 4 male and 3 female adults of P. direptor(Van Duzee) were collected. The finding of P. praedator and P. nigripennis represents new records for Washington state. Prior collection records for P. praedator list various California locations from La Jolla in the south to Bodega Bay in the north (Wheeler 1897; Cole 1969) and Departure Bay in British Columbia (Saunders 1928). P. nigripennis has been recorded from Seaward, Alaska (Van Duzee 1924) and Waldport, Oregon (Cole 1969). Cole incorrectly indicated Waldport as being in Washington. P. direptor has been collected from Pacific Grove in California, and Ilwaco, Pacific County, Washington (Cole 1969). Specimens of the latter two species, in the James Entomological Collection at Washington State University, are from Seaview, Pacific County, Washington (Fig. 1). Adults were collected during low tide, between 1000 and 1 1 30 hours, by sweep netting close to the shaded regions of rocks covered with Fucus Deceived February 12, 1983. Accepted July 25, 1983. ^Scientific Paper Number 6454, Washington State University, College of Agriculture Research Center, Pullman. Work done under Project 0037.
