This species presents the same dimorphism that is 

 common in many earwigs, that is, there are two forms, 

 niacroldbia and microlahia. It is a very distinct species, 

 distinguished by the unspotted elytra, compressed body, 

 square pygidium, and the form of the forceps. It is, 

 perhaps, in intermediate form between F. htrida or F. 

 auricularia and F. smyQ^nensis.
