Morphology

prescutum = scutum (semi-transparent) = pre + scutum

Formed by the productive prefix 'pre-' added to the anatomical noun 'scutum' to denote the anterior part, so the structural relation is straightforward.

Etymology

The word prescutum is made of pre- ('before') and scutum ('shield'). So it means the 'front shield', which is the front part of an insect's upper thorax.
