246 ENTOMOLOGICAL NEWS COLLECTIONS OF DROSOPHILIDAE (DIPTERA) IN KENYA, WITH DESCRIPTION OF A NEW SPECIES OF DETTOPSOMYIA 1 H. Takada 2 , R.C. Woodruff 3 , J.N. Thompson, Jr. 4 ABSTRACT: Drosophilids (Diptera) were collected by sweeping in 52 localities in Kenya from May to August, 1988. Natural population samples of Drosophila melanogaster were collected from 16 sites to screen for variation in mutation rates and other genetic factors. A total of 37 other species of drosophilid flies were also captured. A new species in the genus Dettopsomyia is described, and three new records are reported. Natural populations of Drosophila melanogaster carry transposable DNA elements that increase mutation rates and cause other genetic changes (Woodruff et al., 1983). Populations differ in the number of active elements in each individual. Since the species is thought to have originated in Africa, collections in Kenya were made by two of us (R. Woodruff, all sites; and J. Thompson, sites 22-31; see Figure 1) to survey transposable DNA levels (Woodruffs al., 1989). A total of 34 locations were sampled. In doing this, 35 other species of the subfamily Droso-philinae and 2 species of the subfamily Steganinae were identified among 1,211 alcohol specimens (deposited at Sapporo University, Sap-poro, Japan) and 36 live strains (maintained at Bowling Green State University, Bowling Green, Ohio). Information on species distributions, collection locations and methods are given below. All collection locations are cross-referenced to the map of Kenya (Figure 1). Information on drosophilid species is sum-marized in Wheeler (1981, 1986), and the Afrotropical drosophilid fauna is discussed in Tsacas et al. ( 1 98 1 ). A new species, Dettopsomyia woodruff, is described, and new distribution records are provided for three species of the subgenus Drosophila: Drosophila mercatorum, D.fulvimacula, and D. virilis. Genus Zaprionus Coquillett 1. Zaprionus tuberculatus Malloch, 1932. Stylops. 1(1): 11. Specimens examined: 144 males and 131 females. Locations: 1, 4-7, 1 1, 14, 16, 20, 26, 28, 29, 31, 34 Collection methods: sweeping and trapping on banana, mango, and other fruit, rotting tomatoes and fungus. ^Received December 29, 1989.
