A morphological and morphometrical study of the closely related taxa Phlebotomus (Paraphlebotomus) sergenti et P. (Paraphlebotomus) similis confirms their specific taxonomic status. Differential characters between these two species are discussed. Males differ by the aspect of the basal process of the coxite which is curved and narrow in the first species whereas straight and thick for the latter. The P. similis process is bigger and tuffer and its style is longer than those of P. sergenti. Females differ by the morphology of the armature of the pharynx and by the number of rings of the spermatheca. Distribution areas of these species are described. P. similis is a North-Eastern Mediterranean species (from Yugoslavia to western Turkey and Azerbaïdjan). P. sergenti is present from Canary Islands (Spain) to India. From these data, the settlement of Paraphlebotomus in the Mediterranean basin may have occurred during the Miocene age. From an Asiatic common ancestor, two migration routes are proposed. One, north of the Paratethys Sea, may be responsible for the isolation of P. similis. The other, south of the Paratethys and Tethys Seas, may have contributed to the individualisation of P. sergenti. The authors consider P. similis as a suspected vector of Leishmania tropica.
对密切相关的物种—— Sergenti 白蛉（副白蛉属）和 Similis 白蛉（副白蛉属）进行的形态学和形态测量学研究证实了它们各自的分类地位。文中讨论了这两个物种之间的鉴别特征。雄性的区别在于抱器基节的形态，第一种的抱器基节弯曲且狭窄，而第二种则是直的且粗壮。Similis 白蛉的抱器基节更大更厚实，其阳茎比 Sergenti 白蛉的更长。雌性的区别在于咽骨片的形态以及受精囊的环数。描述了这些物种的分布区域。Similis 白蛉是地中海东北部的物种（从南斯拉夫到土耳其西部和阿塞拜疆）。Sergenti 白蛉分布于从加那利群岛（西班牙）到印度的区域。根据这些数据，副白蛉在地中海盆地的定居可能发生在中新世时期。从一个亚洲共同祖先出发，提出了两条迁徙路线。一条是在副特提斯海以北，可能导致了 Similis 白蛉的隔离。另一条是在副特提斯海和特提斯海以南，可能促成了 Sergenti 白蛉的分化。作者认为 Similis 白蛉是热带利什曼原虫的疑似传播媒介。
