Phallus measurements (mm). (n = 4) Length 0.8–1.0 (mean = 1.0); apex width 0.3 (mean = 0.3); middle width 0.5 (mean = 0.5); basal width 0.6–0.7 (mean = 0.6); lateral apex width 0.3–0.4 (mean = 0.4); lateral medial width 0.5–0.6 (mean = 0.5); lateral basal width 0.5 (mean = 0.5). Female measurements (mm). (n = 17) Body length 24.5–29.9 (mean = 26.6); pronotum length 5.9–7.2 (mean = 6.5) tegmen length 3.1–4.8 (mean = 3.9); hind femur length 13.0–15.4 (mean = 14.3); dorsal ovipositor valve length 1.3–2.2 (mean = 1.7); ventral ovipositor valve length 1.2–2.2 (mean = 1.7).
