Abstract: | The first positively associated larva and pupa of Cernotina are described. Tentative diagnoses are provided for distinguishing them from those of other genera of Nearctic Polycentropodidae, especially Polycentropus s.lat. , which Cernotina most strongly resembles. The larva of Cernotina may be distinguished from that of Polycentropus s.lat. by protarsi nearly as long as the protibiae and by sharply curved anal claws, each bearing a single dorsal accessory spine. The pupa of Cernotina may be distinguished from that of Polycentropus s.lat. by a fringe of swimming hairs on the protarsi, the absence of baso-lateral setae on the mandibles, only one pair of large bristles on the anterior portion of its labrum, and only about 10 setae on each of the rounded apical abdominal lobes. |
