Material examined. Lectotype ♀, [ECUADOR, Napo], Archidona (BMNH), here designated. Paralectotype ♀ [ECUADOR, Napo], Archidona (BMNH), here designated. 1♀, ECUADOR, Pichincha, Bellavista Cloud Forest Reserve, 0°00’55”N 78°40’49”W, 2200–2300 m, tropical cloud forest, M.V. light, 24–28.VII.2007, CPDT Gillet leg. (BMNH); 3♂, 4♀, ECUADOR, Napo, Yanayacu Biological Station, 2144 m, 0.60°S 77.89°W, 24–30.XI.2009, D. Forero leg. [EC09_L1] (1♂ 1♀ UCRC; 1♂ 1♀ USNM; 1♂ 2 ♀ MNRJ).
Diagnosis. Head dark brown dorsally (Figs 12–13). Anterior angles of pronotum each with a stout, spine-like tubercle, surpassing lateral margins of each compound eye; anterolateral margins each with 1–2 small tubercles; each humeral angle bilobed apically, anterior lobe with 2–3 processes; posterior margin weakly concave (Figs 1–3). Apex of hemelytral radial vein calloused; corium ivory, reaching anterior margin of abdominal segment VI; membrane reaching anterior margin of abdominal segment VIII on females (Fig. 15) and surpassing abdominal apex on males (Fig. 14). Male genitalia: posterolateral angles of pygophore rounded; inferior layer of ventral rim weakly emarginate, with a bilobed projection medially; parameres acute apically (Figs 18–24). Female genitalia: posterior margin of each gonocoxite 8 rectilinear; posterior margin of each laterotergite 8 acute; laterotergites 9 digitiform (Figs 32–35).
Male genitalia. Dorsal rim concave with 1+1 trapezoidal projections laterally to segment X (Figs 18–19; dr). Inferior layer of ventral rim projected posteriorly, bilobed apically (Figs 20–23; vr). Superior layer of ventral rim depressed medially (Figs 18–21; sl). Posterolateral angles rounded, bearing setae (Figs 18–19; pa). Abdominal segment X rectangular (Figs 18–19, 25; X). Parameres F-shaped; head of paramere blade-like, acute apically; in lateral view, paramere with a rounded, median process bearing setae (Figs 18–21, 24; par). Phallus: limit between sclerotized and membranous area of phallotheca sinuous (Figs 28–29; ph). Ventral conjunctival processes curved toward vesica apically, its dorsal surface concave (Figs 26–31; v cp). Laterodorsal conjunctival processes each digitiform, membranous, shorter than vesica (Figs 28–29; lcp). Vesica cup-like, projected dorsally; dorsal margin strongly sclerotized and emarginated medially (Figs 28–31; v). Ductus seminis distalis curved ventrally, originating from central part of vesica (Figs 30–31; ds). Process of gonopore bilobed apically.
Female genitalia. Gonocoxites 8 longer than wide; each sutural margin parallel basally, sinuous and divergent apically; sutural margins setose, setae covering gonapophyses 8; posterior margins rectilinear (Figs 32–33; gc8). Gonapophyses 8 visible, subtriangular, carinated medially (Figs 32–33; g8). Laterotergites 8 triangular, each longer than wide; posterior margin acute, surpassing tergite 8 (Figs 32–33; la8). Gonocoxites 9 trapezoidal, each with 1+1 tufts of long setae on its disc (Figs 32–35; gc9). Laterotergites 9 depressed basally; lateral margins concave; apices rounded, each barely surpassing tergite 8 (Figs 32–33; la9). Segment X rectangular (Figs 32–33; X). Gonapophyses 9 with 1+1 lateral sclerotized areas placed along with chitinellipsen (Figs 34–35; ch) and 1+1 lateral folds partially covering chitinellipsen (Figs 34–35; lf). Chitinellipsen elliptical (Figs 34–35; ch). Thickening of vaginal intima circular with an anterior subtriangular projection (Figs 34–35; tvi). Median duct of vesicular area sinuous at base (Figs 34–35; md). Capsula seminalis with three finger-like processes (Figs 34–35; cs).
Measurements. Total length, 9.6±0.42 (8.4–11.5); head length, 2.2 ± 0.05 (2.1–2.5); head width, 1.6 ± 0.04 (1.5–1.8); length of pronotum, 1.9 ± 0.06 (1.8–2.3); width of pronotum at base, 4.3 ± 0.16 (3.7–5.1); maximum width of pronotum at humeral angle, 5.0 ± 0.18 (4.5–6.0); length of scutellum, 3.0 ± 0.11 (2.6–3.5); width of scutellum, 2.8 ± 0.10 (2.5–3.3); width of abdomen across third segment, 5.5 ± 0.13 (5.0–5.8).
Distribution. Ecuador (Napo, Pichincha) (Figs 78–79).
