Remarks.

This is a new record for Penang Hill. So far, this species has only been found in human-altered habitats. The most reliable method for determining species identity involves detailed anatomical examination. However, as this specimen is a juvenile, some identifying features may not be fully developed. Based on the available evidence, we tentatively identify it as L. alte .
