摘要

本文报道了一种新的达尔文小黄蜂——kobensis Shimizu sp. nov.(膜翅目:姬蜂科:蚜蜂科)。结果表明,该新种与欧洲的O. osus Gravenhorst, 1829的O. minutus种群有密切的亲缘关系,但可以通过体色全黑,有浅黄色斑点,侧面没有倾斜的外阴凸等形态学特征来区分。这一新记录是日本和远东地区首次记录的O. minutus种群。系统发育分析表明,O. minutus种群作为Ophion s. str.的单系姐妹类恢复较弱。分析还表明,O. minutus种群中的两个分支(O. minutus和O. osus)分化显著。这表明,类群,以及两个包含的分支,可能被视为单独的类群或属。本研究支持了以往对蛇蛇属的综合分类和系统发育研究,并为对具有挑战性的日本和远东蛇蛇属的研究迈出了基础的第一步。

A New Distinctive Darwin Wasp Represents the First Record of the Ophion minutus Species-group (Hymenoptera: Ichneumonidae: Ophioninae) from Japan and the Far East, with an Analysis of DNA Barcode-based Species Delimitation in Ophion.

A new Darwin wasp species, Ophion kobensis Shimizu sp. nov. (Hymenoptera: Ichneumonidae: Ophioninae), is described using the integrated morphological and molecular species delimitation approaches. Our results indicate that the new species is closely related to European O. ventricosus Gravenhorst, 1829 of the O. minutus species-group but can be distinguished using morphological characters, such as entirely black body colour with some light-yellow marks and not inclined epicnemial carina in lateral view. This record of the new species represents the first record of O. minutus species-group from Japan and the Far East. Phylogenetic analysis indicate that the O. minutus species-group is weakly recovered as monophyletic and sister to Ophion s. str. The analysis also indicated that two clades within the O. minutus species-group (O. minutus and O. ventricosus) diverged significantly. This suggests that the species-group, as well as the two included clades, could potentially be treated as separate species-groups or genera. The present study supports previous integrative taxonomic and phylogenetic studies of Ophion and represents a first fundamental step for studies focused on the challenging Japanese and Far Eastern Ophion.
