Definition
Mustilia orthocosta is a nominal species of moth belonging to the family Endromidae (formerly placed in Bombycidae).
Overview
The species is listed in taxonomic checklists of Asian Lepidoptera, where it is placed in the genus Mustilia Walker, 1865. The genus comprises medium‑sized moths primarily distributed in East and Southeast Asia. Detailed information on the biology, ecology, and geographical range of M. orthocosta is scarce in readily accessible literature.
Etymology / Origin
The specific epithet orthocosta derives from the Greek roots ortho‑ (“straight”) and costa (“rib” or “edge”), a term commonly used in Lepidoptera morphology to refer to the leading edge of the fore‑wing. The name likely alludes to a morphological characteristic of the species’ forewing costa.
Characteristics
Accurate morphological data for M. orthocosta are not widely published. Consequently, specifics such as wingspan, coloration, and distinguishing genitalia structures cannot be confirmed at this time. In general, members of Mustilia display robust bodies, relatively broad wings, and patterns that provide camouflage against bark, but whether these traits apply to M. orthocosta remains unverified.
