摘　　要：自从红羊新蚤ＮｅｏｐｓｙｌｌａｈｏｎｇｙａｎｇｅｎｓｉｓＬｉ，Ｂａｉ＆Ｃｈｅｎ，１９８６从宁夏回族自治区的海原和贺兰山林区发现并报道（四川动物５（２）：１－３）以后，青海、甘肃和陕西均先后发现他们以往鉴定为二齿新蚤的大多数为红羊新蚤。本文报道红羊新蚤的地理分布、海拔、主要宿主及鉴别特征的应用。Since the description of Neopsylla hongyangcnsis Li, Bat & Chen.1986 from Haiyuan and Helan Mountain in Ningxia had been published, specimensthat identified as N. bidentatijormis of Qinghai, Gansu and Shanxi were re--examined.We found that most of them were mis--identified. They are really N. hongyangensisinstead of being N. bidentatilormis. While N. bidentatijormis is a flea of medicalimportance, the geographical distribution, host preference and the identificationIcharacters of N. hongyangensis are presented and discussed for comparison.1. N. hongyangensis belongs to the bidentatijormts group of the genus Neopsylla and is near to N. bidentatiformis, but could be readily distinguished from thelater in the male, by the presence of a single median ventral arm branched from thebase of the distal arm of the 9th sternite. In the female, the anal stylet is longer,being 3.4--3.7 times as long as broad at the base, instead of 2.5--3.0 times; andwith fewer bristles on the 7th sternite, e. g. 5--6 in the main row, 14--16 smaller,ones anteriorly instead of 7--9 in the main row, and 27--30 smaller ones anteriorly.The median sclelotized portion of the aedeagal crochet being pointed basaly istriangular in N. hongyangentis instead of being broad basaly, the membraneous flapswhich vary in shape anterior and posterior to the sclerotized median portion.2. N. hongyangentis is Palaeoarctic with the altitute of 1 500--5 000M, whileN. bidentatijormis is below 1 500M. above sea level.3. N. hongyangensis has a low host-specificity, and Cricetulus longicaudata, C.lmigratorius, C. triton are the main hosts. Others are:species of the genera Apodemus, Rxtus, Niviventer, Mas, Marmota etc.4. N. bidentatiformis is a potential vector of plague. While N. hongyangensisis systematically near to it, and had been mixed up with N. bidentatiformis, it conedcause a new problem for the endemic diseaes research and control workers.
