蜂虱是蔷薇科植物的花粉甲虫。该属目前包括两个亚属，Meligethes和Odonthogethes的63个已知种，主要发生在古北界东部。通过对蜂亚科7属11个外类群的169个形态生态特征的分析，探讨了蜂亚科的发生发展。根据线粒体（COI，16 S）和细胞核（CAD）基因的DNA序列数据，对9种蜂、9种齿蜂、3种齿蜂和2种蜂进行了平行的分子生物学分析。形态系统发育重建支持单系的整个属和分支对应的声称的亚属Meligethes S.str.和Odonthogethes。主要的种组大多得到确认，但仍有一些未解决的多分支。分子数据将Ausicogethes的成员（包括42个主要与Ausicaceae相关的W古北种）作为Odonthogethes的姐妹，该分支是Meligethes s. str的姐妹。这种系统发育情况表明，单系Meligethes s. str。Odonthogethes和Aromicogethes应交替视为单系Meligethes的三个亚属，或在一个单系属复合体中的三个属，与相互单系的Aromicogethes和Odonthogethes。分子分析估计这一谱系的起源约在1980年。14-15 Mya来自一个共同的茎，包括Meligethinus。我们推测，Meligethes的祖先专门在中中新世（可能在Langhian时代）的蔷薇科，并随后在晚中新世和上新世更新世期间辐射维持在这个植物家族的营养生态位。这种辐射主要是由于东亚山区系统的地理隔离。结合形态学、寄主植物群丛的祖先状态简约性重建和分子证据，认为蔷薇亚科（Rosasspp.）代表了Meligethes s.str.的祖先宿主，随后是祖先Odonthogethes的独立转移（约。9-15 Mya）分布于悬钩子属（Rosoideae）和蔷薇科绣线菊亚科（Rosaceae Spiraeoideae）的植物上。其他的祖先Odonthogethes可能再次转移到不相关的植物科紫茎泽兰科（可能在中国南方的8-14 Mya），使紫茎泽兰科的分支迅速向西辐射。在线版本包含补充材料，可通过10.1186/s12983-021-00390-4获取。
Meligethes are pollen-beetles associated with flowers of Rosaceae as larvae. This genus currently consists of 63 known species in two subgenera, Meligethes and Odonthogethes, predominantly occurring in the eastern Palaearctic. We analyzed 74 morphological and ecological characters (169 states) of all species, as well as of 11 outgroup species from 7 Meligethinae genera (including Brassicogethes), to investigate their phylogeny. We also conducted a parallel molecular analysis on 9 Meligethes, 9 Odonthogethes, 3 Brassicogethes and 2 Meligethinus species based on DNA sequence data from mitochondrial (COI, 16S) and nuclear (CAD) genes. Morphological phylogenetic reconstructions supported the monophyly of the whole genus and clades corresponding to purported subgenera Meligethes s.str. and Odonthogethes. Main species-groups were mostly confirmed, however some unresolved polytomies remained. Molecular data placed members of Brassicogethes (including 42 mostly W Palearctic species associated with Brassicaceae) as sister to Odonthogethes, with this clade being sister to Meligethes s.str. This phylogenetic scenario suggests that monophyletic Meligethes s.str., Odonthogethes and Brassicogethes should be regarded alternatively as three subgenera of a monophyletic Meligethes, or three genera in a monophyletic genus-complex, with mutually monophyletic Brassicogethes and Odonthogethes. Molecular analyses estimated the origin of this lineage at ca. 14–15 Mya from a common stem including Meligethinus. We hypothesize that the ancestor of Meligethes specialized on Rosaceae in the Middle Miocene (likely in Langhian Age) and subsequently radiated during Late Miocene and Plio-Pleistocene maintaining a trophic niche on this plant family. This radiation was primarily due to geographic isolation in E Asiatic mountain systems. Combined evidence from morphology, ancestral state parsimony reconstruction of host-plant associations and molecular evidence suggested that Rosoideae (Rosa spp.) represented the ancestral hosts of Meligethes s.str., followed by an independent shift of ancestral Odonthogethes (ca. 9–15 Mya) on Rubus (Rosoideae) and members of Rosaceae Spiraeoideae. Other ancestral Odonthogethes probably shifted again on the unrelated plant family Brassicaceae (maybe 8–14 Mya in S China), allowing a rapid westward radiation of the Brassicogethes clade.
