Etymology: Trimma: Greek, trimma, -atos = something crushed (Ref. 45335);  macrophthalmus: Origin of name not given, but presumably from ‘macro’ for large and the Greek noun ‘opthalmos’, meaning eye; originally spelled as ‘macrophthalmus’, and the spelling is retained because the second half of the specific name is a noun; thus treated as noun in apposition.
