Justification
This species is known only from one specimen. It is listed as Data Deficient in view of continuing uncertainties as to its extent of occurrence, status and ecological requirements. Surveys are required in lowland areas to determine its distribution. If it is found to be restricted to lowland forest, it is likely to be threatened.
