Genitalia. Exposed surface of pygophore castaneous; posterolateral angles moderately divergent, stout, posteriorly depressed, apices rounded (Fig. 5D–F). Parameres yellowish, subparallel to posterolateral angles, attaining apex of segment Xor slightly shorter, cylindrical, apices flattened with subapical denticle (Figs. 5D–F, 6B). Segment X subcylindrical, basal portion membranous forming a line at the limit of sclerotized area (Fig. 5D– F). Phallotheca globose, vesica sinuous, slightly longer than phallotheca (Fig. 7B).

Measurements (n=11): head length 2.40 ± 0.19 (2.80–3.20); width 3.16 ± 0.08 (3.03–3.28); pronotum length 3.66 ± 0.17 (3.30–3.78); width 6.60 ± 0.23 (6.10–6.81); scutellum length 5.73 ± 0.24 (5.35–5.98); width 4.23 ± 0.15 (4.04–4.47); abdomen length 6.27 ± 0.31 (5.68–6.53); width 6.88 ± 0.20 (6.53–7.1); length of antennal segments: I 1.17 ± 0.12 (1.00–1.26); II 1.14 ± 0.09 (1.05–1.26); III 2.18 ± 0.10 (2.04–2.32); IV 2.31 ± 0.11 (2.17– 2.45); V 2.64 ± 0.12 (2.51–2.75); length of labial segments: I 1.60 ± 0.16 (1.42–1.85); II 3.00 ± 0.22 (2.62–3.30); III 2.40 ± 0.21 (2.13–2.75); IV 2.58 ± 0.27 (2.13–2.85); total length 14.75 ± 0.74 (13.57–15.44).
Genitalia. Gonocoxites VIII longer than wide covering the base of laterotergites IX. Posterior margins of gonocoxites VIII over gonocoxites IX rectilinear. Laterotergites IX subrectangular, diagonally directed to apex (Fig. 8B). Arms of gonocoxites IX widening to apex, sclerotized. Vesicular area about six times longer than the combined length of pars intermedialis and capsula seminalis (Fig. 9B).
