Pectinated

The following are the terms used in describing the different forms of antennæ in the Lepidoptera:— 1. Pectinated, when the joints have long processes like the teeth of a comb. If these are on one side only, the antennæ are unipectinated; if on both sides, bipectinated.

Furthermore Patellapis (s. str.) is characterised by the broad, well defined and usually apically rounded basitibial plate of females, the weakly serrated to pectinated inner hind tibial spur of females, the fourth sternum of male[s] with a transverse apical row of coarse bristles, and the helmet-like crest of penis valves.
