Three new halacarid species belonging to the genus Copidognathus are described from the east coast of Zanzibar, Tanzania. Copidognathus corallicolus sp. nov. is characterized by dorsal setae 2 on membranous cuticle between anterodorÂsal plate and ocular plate, posterodosal plate with two single-rosette-pore wide costae, panels on posterodorsal plate subÂdivided, long rostrum extending to base of fourth palpal segment, tibia IV with a ventromedial pectinate seta, and tarsi III and IV with 4:3 dorsal setae. Copidognathus fungiae sp. nov. is a member of C. tamaeus group, and characterized by all ventral plates fused in male, posterodorsal plate with two 2- to 3-rosette-pores wide costae, palp a little surpassing anterior end of rostrum, second palpal segment with spinular lamella ventrodistally, ventrolateral lamella of telofemur I with medial edge slightly protruded, and patella IV with 4 setae. Copidognathus ungujaensis sp. nov., a member of C. bairdi group s. str., is closely allied with C. sidellus Bartsch, but differs from it by the presence of areola below second coxal region, almost straight anterior margin of posterodorsal plate, 2 rosette pores between gland pores on posterodorsal plate, lateral and middle costae not joining anteriorly, and more elongated anterior areola on anterodorsal plate.
