【摘要】 <正> 关于北京市蚊种的研究过去已做了很多,但至今还没有报告过赛保蚊(Theobaldia)属的蚊子。1954年春季我们在西山发现一种属于这一属的蚊子。 根据Barraud氏的记载Theobaldia 属的特征有以下几点:成蚊胸部侧面有5—10根气孔毛(spiracular bristles),成一行排列在前气孔之前;在翅的缘下脉基部(remigium)翅的下面有细毛;腿的末端没有爪垫。幼虫的呼吸管基部有一对毛束。更多还原

【Abstract】 1.Many studies have been made on mosquitoes in Peking, but so far the genus Theobaldiahas not been represented. On May 11th, 1954, a number of larvae were collected from a fresh water pool beside ahil1y stream in Wo-fo-see, Western Hill, near Peking. On examination of the larvae, pupaeand hatched adults, they were found to be a species of Theobaldia. A careful study of the material showed that the mosquito was Theobaldia kanayamensisYamada. This species is nearly related to Theobaldia niveitaeniatus (Theobald) in Tibet, but differsfrom the latter in the following points: (1)The golden scales on the mesonotum form definite lines which comply well with thedeseription of the species. (2) Besides other characters of the male genitalia, the present species has on the styletwo terminal spines instead of one as in the case of T. niveitaeniatus. 2.The larvae and pupae were desoribed, which do not seem to have been described before. 3.This is evidently a rare species, as it had never been encountered before though numerousinvestigations were made by others as weil as by us in the past years.更多还原
