We examined the morphology, colour patterns and genetic relationships of Nososticta populations allied to N. salomonis (Selys) from across Melanesia. Seven species-level taxa are recognised in the N. salomonis 'complex': N. africana (Schmidt), N. boonei sp. nov., N. chrismulleri Theischinger & Richards, N. hedigeri sp. nov., N. salomonis (Selys), N. stueberi sp. nov., and N. tagula sp. nov. All of these species are black damselflies with blue markings, and they differ from all other Nososticta by having: 1) a prominent spike on the male superior appendage, 2) a prominent angular base of the male inferior appendage, and 3) a complex posterior lobe on the female pronotum bearing two pairs of processes in the rough shape of a chair when viewed laterally. A molecular phylogeny based on the DNA barcode fragment of the COI gene plus two nuclear genes indicates that these seven species are closely related, but more extensive sampling of Nososticta species is required to confirm that they form a monophyletic group.
我们研究了美拉尼西亚各地与所罗门诺氏蟌（N. salomonis，赛利斯）相关的诺氏蟌种群的形态、色斑和遗传关系。在所罗门诺氏蟌“复合体”中识别出7个物种级分类单元：非洲诺氏蟌（N. africana，施密特）、布氏诺氏蟌（N. boonei，新物种）、克里斯穆勒诺氏蟌（N. chrismulleri，泰申格和理查兹）、赫迪杰诺氏蟌（N. hedigeri，新物种）、所罗门诺氏蟌（N. salomonis，赛利斯）、施图贝里诺氏蟌（N. stueberi，新物种）和塔古拉诺氏蟌（N. tagula，新物种）。所有这些物种均为带有蓝色斑纹的黑色豆娘，它们与所有其他诺氏蟌的区别在于具有：1）雄性上附器上有一个突出的尖刺；2）雄性下附器基部有一个突出的角；3）雌性前胸背板上有一个复杂的后叶，从侧面看时带有两对呈大致椅子形状的突起。基于细胞色素氧化酶亚基I（COI）基因的DNA条形码片段加上两个核基因构建的分子系统发育树表明，这七个物种密切相关，但需要对诺氏蟌物种进行更广泛的采样，以确认它们构成一个单系类群。
