Description

edit

Dryadillo sp. have a cephalon with a frontal lamina (head shield) that does not protrude past the end of the cephalon. The epimera (side plates) of their first segment do not have a thickened margin and their postlateral corner has a shallow cleft with the inner lobe much shorter than the outer one. The epimera of their second segment have a semicircular ventral lobe.

Their telson has a conical shape and their uropod has a dorsal medial tooth and short exopod[3].

Distribution

edit

This genus has been found in China, Hong Kong, Indonesia, Macau, Taiwan, and Vietnam. Several species appear to be endemic to islands in Indonesia[1][4]. Some species in this genus are cave-dwelling and have troglomorphic traits[5].
