1 The six numbers are, in order from left to right: fore femur prolateral and retrolateral, mid femur prolateral and retrolateral, hind femur prolateral and retrolateral. ‘1’ means that an apical spine is present, ‘0’ means that an apical spine is absent.
2 Body length is measured from the apex of the fastigium to the posterior margin of the suranal plate.
