differing from contribal genera by the unique arrangement of the gonopod parts, including the promeres being positioned completely laterally rather than anteriorly in relation to the opisthomeres, and the solenomere being protected by specific grooves/channels in the anterior process of the opisthomere and in the distomesal process of the promere; as well as by the following combination of other characters: opisthomere with a lobe-like basoposterior process being mostly fused to CBO, ending with a freely protruding, branched, papillose, apical outgrowth, a well-developed anterior process, partially enveloping the solenomere, and a very slender, tapering solenomere, without any distinct apical structures.

It is also possible that one or both of these structures take part in copulation, facilitating the penetration of the solenomere into the vulval opening.
