The antennae have the typical shape of the Nematocera (multi-segmented, each segment bead-like), but the first segmnet is strongly swollen compagered to the other ones. The first segments here are long plumose, the terminal ones have very few hairs. The hairs closest to the base of the antennae are spread out (the outher light fan), the later ones form the brush-like bundle (leaf-like part) and the tip appears to be bare (inner rod bearing tiny elelments).
