Male genitalia
Vinculum entirely composed of a V-shaped saccus that forms a sac over (ventral to) the basal half of the sacculi (valvae can only be laid flat if this is torn open); no side arms. Tegumen tubular with a ~quadrate dorsal plate and fairly broad sidearms that articulate with the costa. Gnathos with short sidearms and a broad ovoid median lobe. Sacculus somewhat variable: AVM straight or very shallowly concave; ALA obtusely rounded or obtusely angular; LM rounded or fairly straight, somewhat crenate/serrate; PLA acute, unadorned. Valvula elongate with a rounded apex; interposed between sacculus and costa; extending a little further laterally than sacculus. Costa a short sclerotised bar connecting valvula and tegumen. Transtilla very fine, projects anteriorly from base of costa, not meeting in midline. Juxta an elongate fold connecting anterior end of sacculi/dorsal surface of saccus to the ventral surface of the base of the tunica. Tunica simple, curved through 90° ventrally in basal ½, narrowing towards apex. Vesica much shorter than tunica with a single cornutus at junction of vesica and tunica; annulus not discernible. Male genital key: Sacculus with finely serrate lateral and posterior margins, without a distinct anterolateral projection and ending in an acute posterolateral angle without a distinct projection.

Female genitalia
Anal papillae elongate, domed. Posterior apophyses 3.5-4xOP. Dorsal plate of A8 weakly sclerotised, except for a band at the anterior margin. Ventral plate of A8 slightly notched at posterior margin and bearing AP at anterolateral margins. Anterior apophyses 1½xOP. Ostium and antrum form a pouch ventral to A8. Ostium opens in the ventrodorsal (transverse) plane; bounded dorsally by the ventral plate of A8 and laterally by sclerotised bands connected to A8. Antrum distinctive; funnel-shaped, narrowing anteriorly from ostium and directed to the left. DB largely hyaline; fairly straight in posterior ⅓, a shallow sparsely spiculate single coil in middle ⅓, 2 tight coils in anterior ⅓; junction with BC distinct. BC elongate ovoid; signum a small, somewhat triangular, thorn. Female genital key: Antrum asymmetrically sclerotised (more heavily on the right) and curves to the left
