Diagnosis. Head dark brown dorsally ( Figs 12–13 View FIGURES 12 – 17 ). 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 View FIGURES 1 – 11 ). 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 View FIGURES 12 – 17 ) and surpassing abdominal apex on males ( Fig. 14 View FIGURES 12 – 17 ). 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 View FIGURES 18 – 31 ). Female genitalia: posterior margin of each gonocoxite 8 rectilinear; posterior margin of each laterotergite 8 acute; laterotergites 9 digitiform ( Figs 32–35 View FIGURES 32 – 35 ).

Male genitalia. Dorsal rim concave with 1+1 trapezoidal projections laterally to segment X ( Figs 18–19 View FIGURES 18 – 31 ; dr). Inferior layer of ventral rim projected posteriorly, bilobed apically ( Figs 20–23 View FIGURES 18 – 31 ; vr). Superior layer of ventral rim depressed medially ( Figs 18–21 View FIGURES 18 – 31 ; sl). Posterolateral angles rounded, bearing setae ( Figs 18–19 View FIGURES 18 – 31 ; pa). Abdominal segment X rectangular ( Figs 18–19, 25 View FIGURES 18 – 31 ; 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 View FIGURES 18 – 31 ; par). Phallus: limit between sclerotized and membranous area of phallotheca sinuous ( Figs 28–29 View FIGURES 18 – 31 ; ph). Ventral conjunctival processes curved toward vesica apically, its dorsal surface concave ( Figs 26–31 View FIGURES 18 – 31 ; v cp). Laterodorsal conjunctival processes each digitiform, membranous, shorter than vesica ( Figs 28–29 View FIGURES 18 – 31 ; lcp). Vesica cup-like, projected dorsally; dorsal margin strongly sclerotized and emarginated medially ( Figs 28–31 View FIGURES 18 – 31 ; v). Ductus seminis distalis curved ventrally, originating from central part of vesica ( Figs 30–31 View FIGURES 18 – 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 View FIGURES 32 – 35 ; gc8). Gonapophyses 8 visible, subtriangular, carinated medially ( Figs 32–33 View FIGURES 32 – 35 ; g8). Laterotergites 8 triangular, each longer than wide; posterior margin acute, surpassing tergite 8 ( Figs 32–33 View FIGURES 32 – 35 ; la8). Gonocoxites 9 trapezoidal, each with 1+1 tufts of long setae on its disc ( Figs 32–35 View FIGURES 32 – 35 ; gc9). Laterotergites 9 depressed basally; lateral margins concave; apices rounded, each barely surpassing tergite 8 ( Figs 32–33 View FIGURES 32 – 35 ; la9). Segment X rectangular ( Figs 32–33 View FIGURES 32 – 35 ; X). Gonapophyses 9 with 1+1 lateral sclerotized areas placed along with chitinellipsen ( Figs 34–35 View FIGURES 32 – 35 ; ch) and 1+1 lateral folds partially covering chitinellipsen ( Figs 34–35 View FIGURES 32 – 35 ; lf). Chitinellipsen elliptical ( Figs 34–35 View FIGURES 32 – 35 ; ch). Thickening of vaginal intima circular with an anterior subtriangular projection ( Figs 34–35 View FIGURES 32 – 35 ; tvi). Median duct of vesicular area sinuous at base ( Figs 34–35 View FIGURES 32 – 35 ; md). Capsula seminalis with three finger-like processes ( Figs 34–35 View FIGURES 32 – 35 ; cs).
