Syntergosternite 7+8 as long as high in lateral view, orange, with golden microtrichosity. Epandrium bright orange. Cercus orange proximally and brown distally. Cercus in lateral view progressively narrowing towards the apex, with the dorsal margin angulated and a dorsal notch. Cercal apex acute in lateral view. Surstylus orange, finger-shaped, with a rounded apex. Pregonite with dorsal membranous extension. Postgonite tongue-shaped, straight in lateral view, with an undulated apex. Basi- and distiphallus connected by a desclerotized strip. Phallic tube short and straight. Juxta with a demarcated connection with the phallic tube. Juxta bilobed, each lobe with an acute apex. Lateral styli fused and forming only one broad tube. Vesica absent.

Variable features. Outer vertical seta of same size as postoculars. Chaetotaxy: dorsocentrals = 0 + 3 (anterior one shorter).
