interstriae 1 laterally broadened from basebase:
point or edge closest to the body; opposite of apex

pertaining to the elytral declivity
midpoint then narrowing towards apexapex:
point or edge furthest from the body; opposite of base
; discaldiscal:
pertaining to the disc of either the pronotum or elytra
interstriae that are two times the width of discaldiscal:
