IUCN Red List Status: Not Evaluated (N.E.) Ref. (130435)
Threat to humans:  harmless
Country info:  A single MNHN specimen (MNHN 2002-2974) was collected from the country, is most probably identical with this species. However, since the specimen is heavily damaged, it was not included within the type series (Ref. 75138).
