It is interesting to note that by external characters this genus 

 scarcely differs from Forficula, except in the slender forceps and 

 spined pygidium. The validity of the genus is confirmed by a 

 study of the genital armature. The metaparameres are regularly 

 convex externally, straight internally and acute at the apex, 

 which is unusual in Forficula. 



Doru bimaculatum Fabr. will have to be removed to a 

 distinct genus, as the metaparamera are apically rounded, as in 

 Forficula, but it differs in several features from that genus.
