Abreviattions: ev = evaporatorium; ms = mesopleura; mt = metapleura; o = ostiole. Scale bars: 11–12 = 2 mm; 13–16 = 0.5 mm. 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 ).
