Data from: Taxonomic revision of the Malagasy Camponotus subgenus Mayria (Hymenoptera, Formicidae) using qualitative and quantitative morphology

The Camponotus subgenus Mayria is revised based on the analysis of both qualitative morphological characters and morphometric traits. The multivariate analysis combined the Nest Centroid (NC)-clustering method and Partitioning Algorithm based on Recursive Thresholding (PART) function to generate species hypotheses based on 19 continuous morphological traits of minor workers. The proposed species hypotheses were confirmed by cumulative Linear Discriminant Analysis (LDA). Morphometric ratios for the subsets of minor and major workers were used in species descriptions and redefinitions. In this study, 14 species are recognized, of which seven are newly described: C. lamosy sp. n., C. liandia sp. n., C. mainty sp. n., C. manabo sp. n., C. raina sp. n., C. sada sp. n., C. tanosy sp. n. Four species are redescribed: C. christi Forel, C. dromedarius Forel, C. lubbocki Forel, and C. repens Forel. The following are raised to species and redescribed: C. foersteri Forel stat. n., C. maculiventris Emery stat. n., and C. pulcher stat. n. The following are synonymized under C. foersteri: Camponotus cambouei Forel, syn. n.; C. christi ambustus Forel, syn. n.; C. christi ferrugineus Emery, syn. n. and C. pictipes Forel, syn. n. The following are synonymized under C. lubbocki: Camponotus lubbocki christoides Forel, syn. n. and C. lubbocki rectus Forel, syn. n. Also included in this revision are an illustrated species identification key, taxonomic discussions, images, and distribution maps for each species superimposed with the ecoregions of Madagascar.

本研究基于定性形态特征与形态测量性状的综合分析，对弓背蚁属（Camponotus）Mayria亚属开展分类修订。本研究结合巢心（NC）聚类法与基于递归阈值的划分算法（PART）函数开展多元分析，基于小型工蚁的19项连续形态性状构建物种假说。所提出的物种假说经累积线性判别分析（LDA）得到验证。研究采用小型工蚁与大型工蚁的形态测量比值，完成物种的描述与重新界定。本研究共确认14个物种，其中7个为新种：C. lamosy sp. n.、C. liandia sp. n.、C. mainty sp. n.、C. manabo sp. n.、C. raina sp. n.、C. sada sp. n.、C. tanosy sp. n.。另有4个物种得到重新描述：C. christi Forel、C. dromedarius Forel、C. lubbocki Forel与C. repens Forel。以下类群被提升为有效物种并予以重新描述：C. foersteri Forel stat. n.、C. maculiventris Emery stat. n. 及 C. pulcher stat. n.。以下类群被归为C. foersteri的同物异名：Camponotus cambouei Forel, syn. n.、C. christi ambustus Forel, syn. n.、C. christi ferrugineus Emery, syn. n. 与 C. pictipes Forel, syn. n.。以下类群被归为C. lubbocki的同物异名：Camponotus lubbocki christoides Forel, syn. n. 与 C. lubbocki rectus Forel, syn. n.。本次分类修订还包含各物种的鉴定图文检索表、分类学讨论、物种影像，以及叠加马达加斯加生态区图层的物种分布地图。
