Fig 1.
Adult Euplatypus parallelus antennae in dorsal vision.
E. parallelus have a geniculate antenna, is sensory appendage on either side of the rostrum, and composed of 6 segments, namely the scape, 4-segmented funicle, and club. The antennae of females are significantly longer than males. A: Geniculated antennae of E. parallelus. B: Club. C: Funicle. D: Scape. Cl: Club; Fu: Funicle; Sc: Scape.
