MORPHOLOGY OF THE HEAD OF SERICODERUS LATERALIS (COLEOPTERA, CORYLOPHIDAE) WITH COMMENTS ON EFFECTS OF MINIATURIZATION

摘要

The mouthparts and musculature of the head of Sericoderus lateralis are described. It is shown that the mouthparts of minute beetles can keep the complex structure and they are not significantly affected by miniaturization. Such a stability allows us to use these features in macrosystematics of groups with various body sizes.
