Amber drosophilids

23 p. : ill. ; 26 cm.Includes bibliographical references (p. 23)."All the known fossils of Drosophilidae occurring in amber are treated. Neotanygastrella wheeleri, new species, is named, redescribed (cf. Wheeler, 1963) with respect to certain features, and a holotype and paratype are designated for the two specimens from Chiapas, Mexico. Seven new species are described and two others are recorded from amber of the Dominican Republic (approximately early Miocene in origin): Chymomyza primaeva; Drosophila (D.?) poinari; D. (Hirtodrosophila) paleothoracis; D. succini (incertae sedis); Miomyia io, new genus; Protochymomyza miocena, new genus; Scaptomyza dominicana; and two Drosophilinae species (A and B) incertae sedis. Relative genealogical relationships for some drosophiline genera and subgenera are briefly discussed. Illustrations and photographs of the specimens are included, as well as ideas on significance of some of the fossils for Caribbean historical biogeography. A key to amber-fossilized Drosophilidae is provided"--P. [1]
