Taxonomy
Superfamily: Geometroidea Family: GeometridaeSubfamily: LarentiinaeTribe: XanthorhoiniP3 Number: 910260.00 MONA Number: 7416.00 MONA Synonym: Orthonama centrostrigaria
Identification

Adult Markings: A medium sized Wave with sexually dimorphic wing markings. Males have a pale grayish or brownish median band bounded on the basal side with a chocolate brown area that extends to the antemedian. A similar chocolate brown band also exists on the outward side bordering the postmedian but below the cell this band changes sharply to a paler brown. Females are similar but have a blackish median band. Males of Orthonama obstipata are similar to female centrostrigaria in having a blackish median area, but have paler brown between the black median area and the whitish antemedian and postmedian lines (Forbes, 1948). The apex is also marked with a dark wedge in centrostrigaria but is pale in obstipata and bounded below by a dark dash or shade. Additionally, the postmedian in obstipata is usually incurved where it meets the costa but is either slightly excurved or straight in centrostrigaria.
Wingspan: 20 mm
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
