Morphology of the apical part of the abdomen

Male ( Figs. 2A–L , 3A–B and 4A–F ): Tergum X sclerotized. Epiproct with posterior margin variable. Cercus cylindrical, sclerotized and hirsute, with apical our sub-apical spine. Paraproct bilobulated. Subgenital plate trapezoidal and flat. Styles digitiform (absent in Polycleptis ). Epiphallus conical. Titillator dorsally reversible. Titillator sclerites together at the middle line, keel-shaped, with sheet-shaped lateral apodeme. Titillatory processes articulated, stick-shaped and asymmetric apex, with variable apical spines (absent in Polycleptidella ).

Female ( Figs. 5A–H and 6A–D ): Te rg u m X, epiproct, cercus and paraproct as in male, but less developed and without specializations such as protuberances, spines and pronounced curvatures. Ovipositor ensiform, slightly sharp at the apex towards its dorsal margin. Subgenital plate transverse, t r a p e z o i d a l, w i t h v a r i a b l e m a rg i n a l p r o c e s s e s. Spermatheca is a flexible capsule, oval or spherical. Spermathecal duct of variable length. Accessory gland is a single duct folded towards the capsule.
