两性异形
Usually among the smaller members of their family, these beetles are of a slender shape – particularly the 胸節 (昆蟲) is markedly less wide than the wings, while the 翅鞘 tips are often pointed. They differ from most other longhorn beetles in that the 觸角e are not directly adjacent to the 複眼s. Hence, the latter are generally oval in outline, rather than having an indentation where the antennae originate, or even being divided by them. In addition, 两性异形 is not infrequently seen in lepturines; usually, longhorn beetles are not dimorphic or only have longer antennae in males.
