from the only collection locality in Hong Kong, it was noted that the number of teeth on the masticatory margin are not consistent but were always between three and five. Teeth were either conspicuous or barely discernible from the mandible margin, suggesting these teeth might be worn down and, or broken. A distinct diastema between the basal tooth and fourth tooth was, however, always present. The utility of teeth count as a differentiable and diagnosable character should likely be treated with caution unless combined with additional less variable characters.

. Specimens from Hong Kong are known only from Sunset Peak, Lantau Island. One collection was by J. R. Fellowes in 1992, and another in 2023 by A. Reshchikov using a ground SLAM trap, which was positioned in a tiny fragment of forest near the top of the mountain which yielded one further specimen. Further sampling efforts by members of Insect Biodiversity and Biogeography Laboratory have yet to collect additional specimens from this locality and from Hong Kong at large. The species small eyes might suggest leaf litter and / or nocturnal foraging.
