Male genitalia
V standard. T arched, waisted. Median lobe of gnathos ovoid. Sacculus rectangular: anterior margin straight (naturally somewhat inrolled); ALA distinct obtuse, no process; LM straight continuous with PP; PLA with a distinct narrow PP, directed posterolaterally; PM shallowly concave. Valvula broad. Transtilla robust, sinuate. Juxta a laterally compressed midline keel. Tunica pronged, both prongs with a small subapical tooth. Vesica about as long as tunica; annulus narrow discrete; curve weakly sclerotised. Cornuti at base (anterior end) of vesica: a moderate comb of many fine spines anterior to a small clump of ~3 short spines. Male genital key: Transtilla without any very distinctive feature; sacculus with a straight lateral margin ending in a posterior process at least half as long as the lateral margin

Female genitalia
Anal papillae pointed. Posterior apophyses ~2.5xOP. Anterior apophyses ~1.5xOP. Ostial plate slightly elongate; posterior margin slightly notched in midline; lateral margins slightly rounded. A pair of carinae on ventral surface diverge anteriorly from the midline of the posterior margin to the ostium, the carinae meeting again to form the anteroventral boundary to the ostium. Dorsal plate of A8 hyaline. Ostium at anterior margin; dorsal surface of ostium formed by the ostial plate between the carinae, with a midline extension of the sclerotisation into the dorsal wall of the antrum. Antrum shorter than OP, diffusely sclerotised. Ductus bursae long (~10xOP); posterior ⅔ with a loose coil, then 2 tight anterior coils, then a short straight section to junction with CB; DB narrower than antrum, fairly even diameter, slightly broader in anterior coils. Sclerotisations: circumferential-spiculate + linear from junction with antrum for the posterior half of the posterior coil ~4xOP, the linear sclerotisation extending posteriorly into the antrum; smudgy-diffuse in anterior coils. DS enters in 2nd (nearest CB) anterior coil. Junction with bursa distinct. Bursa elongate ovoid. Signum a large thorn with a broad base-plate and a strong curved spike, shorter than the diameter of the base plate. Female genital key: Corpus bursae with a medium-sized thorn signum, without an additional linear spiculate patch; ductus bursae with heavy spiculation extending from antrum for a length greater than that of the antrum and ostial plate together; ostium a tear-drop-shaped incision reaching close to the anterior margin of the ostial plate.
