The following species have much in common but are 

 clivisable into several genera. The common characteristics 

 are the divided saccus; the strong spine of the cornutus; 

 the absence of uncus; the flying socii, that is where the 

 socii terminate in a pair of chitinised, curved, slender hooks; 

 the generally well-developed sacculus: the bursa much 

 thickened often in folds and spined. 



Genus 5. type

 in long, fused arm; uncus absent; socii weak, broad, curved 

 inwardly. iEdceagus stout, orifice pointed; cornutus a

 The development is too pronounced to be included in the 

 other genera. 



Valva pointed; sacculus broad, produced in a long brush 

 of spines; transtilla a central arm, tip curved; socii reduced 

 to two weakly chitinised lobes set with fine hairs. iEdceagus 

 geniculate: cornuti a band of short, thick spines.
