Antennal teratology in Ammophila sabulosa (Hymenoptera: Sphecidae)

Year: 2026
Type: article
Abstract: A male Ammophila sabulosa specimen exhibiting antennal teratology is reported. Both antennae have 12 segments instead of the typical 13. Partial fusion of antennal segments (incomplete symphysocery) is present on both antennae, involving segments 4 and 5 on the left antenna and segment 4 on the right antenna. Additionally, the terminal segment of the left antenna is shorter than that of the right antenna. This represents a rare case of antennal malformation in Ammophila, characterized by a reduced number of antennal segments and bilateral asymmetry.
