Abstract:

The subfamily Dacinae (Diptera: Tephritidae) from Hainan Province, China, is surveyed and reviewed. The following 14 species are recognized: Bactrocera (Bactrocera) dorsalis (Hendel), B. (B.) latifrons (Hendel), B. (B.) rubigina (Wang et Zhao), B. (B.) wuzhishana Lin et Yang sp. nov., B. (Sinodacus) hochii (Zia), B. (Zeugodacus) abbreviata (Hardy), B. (Z.) caudata (Fabricius), B. (Z.) cilifera (Hendel), B. (Z.) cucurbitae (Coquillett), B. (Z.) diaphora (Hendel), B. (Z.) scutellata (Hendel), B. (Z.) tau (Walker), Dacus (Callantra) haikouensis Wang et Chen, Dacus (Dacus) hainanus Wang et Zhao. B. (B.) wuzhishana Lin et Yang sp. nov. is differentiated from all other congeners of Bactrocera by having: 1) 2 large black spots on sides of face; 2) 2 lateral postsutural yellow vittae on scutum rather narrow and short, extending to a level with postsutural supra-alar setae; 3) costal band confluent with vein R₂₊₃ and slightly expanded apically; and 4) fore femora entirely black, mid femora black with the basal 1/2 yellow, hind femora black with the basal 3/5 yellow; abdomen entirely black. A check list and key to species of the Dacinae from this island is provided.
