Perkinsyllis is recorded for the first time in Brazilian waters with three species, two of which are new to science. Perkinsyllis longisetosa has unidentate dorsal simple chaetae, with coarse spinulation; bidentate blades of falcigers, with a rounded distal tooth and coarse spines; and spiniger-like dorsal-most compound chaetae. Perkinsyllis koolalyoides sp. nov. has dorsal simple chaetae unidentate on anterior-most chaetigers, bidentate to distally bifid on remaining chaetigers, with distal-most spine reaching beyond level of subdistal tooth; compound chaetae as falcigers with bidentate blades with long spines, distal-most spines reaching beyond the level of the subdistal tooth; spiniger-like chaetae absent. Perkinsyllis biota sp. nov. has dorsal simple chaetae unidentate on anterior-most chaetigers and distally bifid, with short spinulation on remaining chaetigers; bidentate blades of falcigers with long spines, distal-most spines reaching beyond level of subdistal tooth; and 1–5 spiniger-like dorsal-most compound chaetae, bidentate, with short spinulation. We present a key to all described species of Perkinsyllis, including an Australian species referred to this genus for the first time.
