Abstract

<abstract abstract-type="main"> <title>Abstract</title> <p>This study reports genome size (C‐value) estimates for seven species of ladybird beetles (Coleoptera: Coccinellidae) in Japan using flow cytometry. The results demonstrated genome sizes of 1.0–1.4 Gb in four closely related phytophagous ladybird beetles belonging to the <italic>Henosepilachna vigintioctomaculata</italic> species complex. These values were approximately two times larger than that of a congeneric phytophagous ladybird beetle <italic>H. vigintioctopunctata</italic> (0.66 Gb), and of two very distantly related common carnivorous ladybird beetles, <italic>Harmonia axyridis</italic> (0.46 Gb) and <italic>Coccinella septempunctata</italic> (0.42 Gb). These lines of evidence suggest that rapid and large genome size increase occurred just after the branching of the common ancestor of the <italic>H. vigintioctomaculata</italic> species complex from other ladybird species.</p> </abstract>
