摘　　要：2017年2月,实验室对芜湖局送检的蝇类样品进行鉴定,该蝇种的特征为:颜脊缺或不发达;翅肩鳞、前缘基鳞黑色;胸部底毛黑色,具黄色绵毛被;肛尾叶侧面观直,末端尖锐并微向后翘起,阳茎下阳体三角形末端尖锐,侧阳体细长,末端不增粗并向前微弯,超过下阳体末端,与端阳体末端齐。同时应用DNA条形码技术对该蝇种进行分子鉴定,依据外部形态及雄性生殖器以及分子生物学特征,鉴定为长阳粉蝇Pollenia labialis Robineau-Desvoidy,1863,该蝇种为中国口岸首次截获。Morphological identification with male genitalia and DNA barcoding identification were performed among specimens intercepted at Wuhu ports of China in February 2017. PoUenia labialis Robineau-Desvoidy, 1863 was intercepted at entry-exit ports of China. It can be distinguished by the following characters： facial keel absent or indistinct, basicosta black; thorax with black hair underneath, yellowish cotton hair; cerei broad, acute. Surstylus with parallel edges, weakly curved in profile, sinuous apically in dorsal view. Aedeagus of labialis-type. Tips of paraphallus weakly sclerotised apically and curved strongly towards midline, tips pointing toward axis of distiphallus at right angles.
