A New Species-subgroup of the Drosophila immigrans Species-group (Diptera, Drosophilidae), with Description of Two New Species from China and Revision of Taxonomic Terminology

The Drosophila (Drosophila) curviceps species-subgroup is newly established for seven known and two new species, viz. D. (D.) brevitabula sp. nov. and D. (D.) papilla sp. nov. D. (Hirtodrosophila) audientis LIN et TING, 1971 is newly transferred to the subgenus Drosophila. The taxonomic relationships among subgroups of the D. immigrans species-group are discussed. New terminology revised by MCALPINE (1981) is adopted to standardize morphological terms for dipterists and to homologize structures throughout the Diptera.
