The name Leucophlebia pinratanai does not appear in widely available, reliable encyclopedic sources. Consequently, detailed information on its taxonomy, distribution, morphology, or ecology cannot be confirmed.
The generic name Leucophlebia is established for a group of moths in the family Sphingidae (hawk moths). The specific epithet pinratanai likely honors an individual with the surname Pinratana, a common practice in zoological nomenclature, possibly referencing a Thai entomologist or collector. However, without verifiable references, the existence and scientific description of this species remain uncertain.
