Specimens of Dactylophlebia carnulenta Pescador & Peters, only known from nymphal stage, were collected and reared in situ. From the material obtained, Archethraulodes spatulus Pescador & Peters, known from male imago and the only known species for the genus, is proposed as junior synonymy with D. carnulenta. Additionally, female imago and subimagos of D. carnulenta are described.
