The phlebotomine sandfly Phlebotomus perniciosus Newstead is a vector of Leishmania infantum Nicolle in the western Mediterranean basin. In northern Morocco it is often caught in sympatry with a closely related species, P. longicuspis Nitzulescu. In the locality of Chefchaouene where females of both species were morphologically distinguishable, none of the collected males exhibited forked copulatory valves, which is considered a specific character for P. perniciosus. They 1st were identified as P. longicuspis. Isoelectrofocusing of 7 enzyme systems was used to compare these specimens with the sympatric females. Two groups of males were separated and assigned to each species by their isoenzyme patterns associated with morphological differences in the shape of the aedeagus and in the number of coxite hairs. Based on our results, a reexamination of the distribution of both species is necessary especially in many locations where P. longicuspis has been identified only from males.
白蛉属的有害白蛉（Phlebotomus perniciosus Newstead）是西地中海盆地婴儿利什曼原虫（Leishmania infantum Nicolle）的传播媒介。在摩洛哥北部，它经常与近缘种长尖白蛉（P. longicuspis Nitzulescu）同域捕获。在舍夫沙万地区，两种白蛉的雌性在形态上可区分，但所采集的雄性均未表现出叉状交配瓣，而叉状交配瓣被认为是有害白蛉的一个特定特征。它们最初被鉴定为长尖白蛉。利用7种酶系统的等电聚焦技术，将这些标本与同域的雌性进行比较。根据与阳茎形状和抱器毛数量的形态差异相关的同工酶模式，将两组雄性分开并分别归为两个物种。基于我们的结果，有必要重新审视这两个物种的分布情况，特别是在许多仅从雄性鉴定出长尖白蛉的地点。
