包括红颈云雀Corypha africana、夏普氏云雀Corypha sharpii、红翅云雀Corypha hypermetra、索马里长嘴云雀Corypha somearia和阿什氏云雀Corypha ashipha的物种复合体包括31个在撒哈拉以南非洲被认可的分类群，其中许多是非常鲜为人知的，有些几十年来没有观察到。只有17个分类群已被研究的分子和全面的形态，发声或其他行为。在这里，我们进行了全面的综合分类学分析，基于羽毛和形态测量学（97%的分类群），线粒体和核基因座（77%），≤ 130万个全基因组单核苷酸多态性（68%），歌曲（许多首次描述; 52%）和其他行为数据（45%）。所有的多型种都是并系的，有8个主要的分支，间隔≤ 6.3-6.8百万年，广泛支持羽毛，形态测量学，歌曲和其他行为。最近的分歧涉及同域分类单元对通常被视为单独的种，而所有分支的分歧，包括C。非洲亚种与其他云雀属的姐妹种对一样古老。我们建议承认九个而不是五个物种，whileC。ashi与C.索马里花S.阿希。其地理分布尚不完全清楚，虽然这9个种通常是帕拉域分布，但有些可能是同域分布。
The species complex comprising the rufous-naped larkCorypha africana, Sharpe’s larkCorypha sharpii, the red-winged larkCorypha hypermetra, the Somali long-billed larkCorypha somalicaand Ash’s larkCorypha ashiencompasses 31 recognised taxa across sub-Saharan Africa, many of which are extremely poorly known and some not observed for decades. Only 17 taxa have been studied molecularly and none comprehensively for morphology, vocalisations or other behaviours. Here, we undertake comprehensive integrative taxonomic analyses based on plumage and morphometrics (for 97% of the taxa), mitochondrial and nuclear loci (77%), ≤ 1.3 million genome-wide single nucleotide polymorphisms (68%), song (many described for the first time; 52%) and additional behavioural data (45%). All polytypic species as presently circumscribed are paraphyletic, with eight primary clades separated by ≤ 6.3–6.8 Myr, broadly supported by plumage, morphometrics, song and other behaviours. The most recent divergences concern sympatric taxon pairs usually treated as separate species, whereas the divergence of all clades includingC. africanasubspecies is as old as sister species pairs in other lark genera. We propose the recognition of nine instead of five species, whileC. ashiis synonymised withC. somalica rocheiasC. s. ashi. The geographical distributions are incompletely known, and although the nine species are generally para-/allopatric, some might be sympatric.
