摘要

Abstract

The xanthid genus

Medaeops

Guinot

1967 currently contains seven species reported from the Indo-West Pacific region. However

only one species

Medaeops

granulosus

(Haswell

1882)

has been recorded from China seas and was once thought to be widespread in the Indo-West Pacific region. In this study

two species of the

Medaeops

granulosus

species-group were identified during the analysis on

Medaeops

crabs from China seas.

Medaeops

japonicus

(Rathbun

1898)

which had previously been considered a junior synonym of

granulosus

is shown to be a distinct species that can be distinguished from

granulosus

by the lower first anterolateral tooth

the larger and concentrated granules on carapace dorsally

and the different shape of the male’s first gonopod. In addition

a new recorded species

Medaeops

edwardsi

Guinot

1967

was reported from China seas for the first time. A molecular analysis was conducted to determine the status of each species

and an updated key for species of the genus

Medaeops

was provided.
