A living female specimen of black fly was collected on a livestock ship Singaporean flag,which came from Port of Portland,Victoria,Australia at quarantine anchorage of Qinhuangdao Port,China on May 2,2014.This female species is placed in the subgenus Morops of genus Simulium based on the peculliar morphological characteristics of the pleural membrane,katepisternum and the basal portion of the wing's radius haired and claw with a small tooth.Because of no pupal exuviae and cocoon,and the relevant identify references available,the specimen was not named.The morphological description of the female specimen is presented to assist with the future researches.The specimen is kept in the Medical Entomology Collection Gallery,Academy of Military Medical Sciences,Beijing,China.The species of subgenus Morops of genus Simulium are found at the southeast districts of Australia,where the ship came from,and distributed in Oceania,the islands of South Pacific,Indonesia,Philippines and Japan up to now.The entry ship loaded with living animals is at high risks to carry introduced blackflies and other biting vectors into naive country,and more attention should be paid on them.%2014年5月2日在秦皇岛港检疫锚地停泊的一艘来自澳大利亚维多利亚州的波特兰大港的运载进口奶牛的入境船舶新加坡籍“吉布雷快车”(M.V.GELBRAY EXPRESS)轮上采获一只活的输入性蚋类雌虫.经鉴定,根据该蚋虫标本的中胸侧膜、中胸下侧片及翅径脉基部具毛和爪基齿等形态结构,符合蚋属Morops亚属的特征.因仅采获一只蚋类雌虫,且无蛹的标本,因此,未定种名,暂命名为蚋属Morops亚属未定种.现将该蚋类雌虫的形态学特征予以描述,以供研究参考.标本保存于军事科学院军事医学研究院医学昆虫标本馆.蚋属Morops亚属的蚋类最早发现于澳大利亚东南部地区,分布于大洋洲和南太平洋诸岛以及印度尼西亚、菲律宾和日本等地.而该轮始发港澳大利亚的波特兰大港即位于澳大利亚东南部地区,所装载的奶牛也来自附近区域.我们应高度重视入境船舶特别是运载动物的入境船舶携带输入性蚋类等病媒生物入侵的危害,确保国门生物安全.
