Definition of epimeron in English:


nounepimerons, epimera

  • (in insects) the posterior part of the side wall of a thoracic segment.

    • ‘Its posterior margin runs at right angles to the longitudinal axis, before swinging inwards to form distinct genal angles and a genal epimeron on the left-hand side.’
    • ‘Where the posterior margin intercepts the lateral margin on either side, a sharp, posteriorly directed epimeron is formed.’
    • ‘Together the epimera on each side form a wall that encloses and protects the space ventral to the sternites.’


Mid 19th century from epi-‘near’ + Greek mēros ‘thigh’.
