Pedilinae

Larvae of Pedilinae can be distinguished from other pyrochroid subfamilies by the presence of an uninterrupted transverse series of asperities on sternum 9. This character state supports the monophyly of Pyrochroidae: Pyrochroinae + Pedilinae + Cononotinae. Adults lack a comprehensive morphological diagnosis in the provided sources.

Larvae have been collected from debris associated with the base of dead, standing trees. Specifically, Pedilus flabellatus larvae were found in forest debris at the base of a dead Pseudotsuga menziesii in coniferous forest habitat.

Documented from western North America; Pedilus flabellatus collected in Mount Hood National Forest, Oregon. Broader geographic range of the subfamily requires additional sources.

Larvae develop in decaying wood and forest debris. The mature larva of Pedilus flabellatus has been described and illustrated. Species identity can be confirmed by rearing larvae to the adult stage.

• PyrochroinaeLarvae of Pyrochroinae lack the uninterrupted transverse series of asperities on sternum 9 that characterizes at least some Pedilinae larvae.
• CononotinaeShares the synapomorphic sternal character state with Pedilinae, supporting their sister-group relationship within Pyrochroidae.
