Male
Resembles X. kempeleni, but can be easily distinguished by the position of the tegular ridge, which is at 6 o’clock.
Female
Strongly resembles X. kempeleni, but can be distinguished by the loop formed by the insemination ducts related to the receptacles. They are apical in X. laetus and median in X. kempeleni.
