Abstract
The callipodidan genus Sinocallipus Zhang, 1993 (Callipodida, Sinocallipodidae) is reviewed within the scope of the Vietnamese fauna. A total of three species are recorded in Vietnam including a new one, Sinocallipus similis sp. nov. All three species are confirmed by morphological and molecular data. An existing identification key of Sinocallipus species is amended to include the new species.

Sinocallipus similis sp. nov.
Diagnosis: This species can be recognized by having up to 79 pleurotergites (in adult females, males with 78), yellowish body, long antennae, 5+5 crests between the ozopores on midbody PTs, almost equally subdivided paraprocts, gonopods with strongly swollen and long gonocoxal process g, and a long, trochanteral process of leg 9 with a pointed tip.
Etymology: From the Latin word “similis” meaning “similar” or “like”. The name denotes the morphological similarity between the new species and Sinocallipus deharvengi from Quang Binh Province in Vietnam.
