(Figs. 1–10, 15–18).
The genital sclerites of male. Supra-anal plate transverse with the distal margin bilobated. In the genital chamber the right-side paraproct hook-shaped with its apex directed apically (Figs. 2–3). Subgenital plate slightly asymmetrical with simple styles (Fig. 4).
Left phallomeres, subdivided in L1 and L2. The first genital sclerite L1 (Fig. 15) very well developed and various areas darkly sclerotized. L1 presenting a cleft with a sigmoid shape and a narrow aperture.
L2 placed medially with two intimately articulated articles. The ventromedial article L2vm (Fig. 16) with a well developed posterior apophysis, which extends dorsally (laterally in the photograph). Its posterior apophysis with a wide base that tappers distally. The dorsal article L2d (Fig. 16) with curved dorsal process under L2vm apophysis.
The right phallomere R2 a hooked sclerite retracted in a soft cuticular tube. The apical third (Figs. 17–18) sclerotized, with a globulous subconic base and a hooked apex with a narrow subapical incision that forms a free blade shaped lamina with a rounded apex.
External morphology of the female (Fig. 6). Size similar to male (Table 1). Female pronotal fissures (Fig. 5) narrower than those of male. Front leg type D, with ventral anterior and posterior margins unarmed and genicular spine absent. Tibial formula with the same distribution as those in the male and nymph [5–6*2*1] [10*2*4] [13*2*8]. The cerci tapering distally with color similar to male. Supranal plate darker than male. Subgenital plate with different shape with a clear subapical area (Fig. 7).
Mature nymph (Fig. 9). Body length 23 mm; pronotum length 4.45 mm; pronotum width 9 mm; interocular distance 2 mm; interantennal distance 2 mm; interocelar distance 1.55 mm.
The nymph with a pronotum not bifissate, but the fissures feeble, insinuated on the pronotal anterior border (Fig. 8). The mature nymph is likely to develop into a female, a deduction based on the absence of the styli (Fig. 10) and the measurements similar to those of the female. The pharate adult can be observed by transparent cuticle; its pronotal lateral wings and fissures are evident.
