Leptodius davaoensis Ward, 1941 # ( Fig. 39B, inset)

Leptodius davaoensis — present record.

Taxonomy: Ward (1941), Yuan et al. (2021).

Type: Holotype ò AMNH-8347 ( Ward 1941).

Type locality: Davao, the Philippines.

Distribution: Southeast and East Asia: from Micronesia (Kosrae Island), Lombok ( Indonesia), to Malaysia and Singapore, the Philippines, and South China ( Yuan et al. 2021).

Habitat: Intertidal and subtidal: beneath or among rock fragments in sheltered shores.

Remarks: Taxonomy of the present species remained poorly known. Locally, this species is not rare along semi-sheltered sandflats and shallow subtidal habitats adjacent to coral communities, and identification of relevant material has been confirmed by J.C.E. Mendoza (ZRC). This species has recently been reported from Hainan ( Yuan et al. 2021), and the presence in Hong Kong is not unexpected. Images showing live coloration of overall habitus and external surface of chela, is provided herein. This species is a new record for the fauna of Hong Kong.
