REMARKS

In the published description by H. Milne Edwards (1853) a locality is mentioned, i.e., “Mers de Chine, Taoranne”. A quick check with Dr Tran Anh Duc and M. Nguyen Thanh Son ( Vietnam National University-University of Science) regarding “Taoranne” has revealed that the locality should be Tourane, the French name of Da Nang, a port city in Vietnam. The term “Indes Orientalis”, or East Indies, was used in colonial times to designate the territories of South and Southeast Asia, including countries like Iran, Pakistan, India, Nepal, Bhutan, Bangladesh, Myanmar, Sri Lanka, Maldives, Thailand, Malaysia, Vietnam, Cambodia, Laos, the Philippines, Brunei, Singapore, East Timor, and Indonesia. It is thus possible to consider that “Indes Orientales” may correspond to “Mers de Chine ”, and “Taoranne” the type locality.

The type status was suspected unknown according to Davie (2002: 214). Four samples of dry Grapsus gracilipes are actually present in the MNHN collection and hereby designated as lectotype and paralectotypes, respectively.
