Diagnosis. Body color light brown ( Figs 54–55). Anterior angles of pronotum each with obtuse projection; each anterolateral margin with three small spines, not evenly distributed; humeral angles quadrate, each with bilobed apex, anterior lobe with 1–2 spines and posterior lobe with a digitoid process; posterior margin weakly concave ( Fig. 11). Apex of scutellum reaching abdominal segment V. Apex of hemelytral radial vein calloused; corium reaching abdominal segment VI; membrane reaching anterior margin of abdominal segment VII on females ( Fig. 57) and surpassing abdominal apex on males ( Fig. 56). Male genitalia: posterolateral angles obtuse; inferior layer of ventral rim emarginate with one projection medially ( Figs 60–65). Female genitalia: posterior margin of each gonocoxite 8 concave; posterior margin of each laterotergite 8 acute; lateral margin of each laterotergite 9 straight ( Figs 74–75).

Male genitalia. Dorsal rim sinuous ( Figs 60–61; dr). Posterolateral angles obtuse ( Figs 60–61; pa). Inferior layer of ventral rim with median projection ( Figs 64–65; vr); superior layer of ventral rim depressed medially ( Figs 62–63; sl). Segment X rectangular ( Figs 62 –63, 67; X). Parameres F-shaped, apex acute dorsally and ventrally; basal process rounded bearing setal tuft ( Figs 60 –63, 66; par). Phallus: limit of sclerotized and membranous area of phallotheca straight ( Figs 70–71; ph). Ventral conjunctival processes each curved toward vesica apically, dorsal surface concave ( Figs 68–73; vcp). Each laterodorsal conjunctival process digitiform, sclerotized, longer than vesica ( Figs 68–73; lcp). Vesica cup-like, strongly projected dorsally, with dorsal margin uniformly concave ( Figs 70–73; v). Ductus seminis distalis ventrally curved, originating in central part of vesica ( Figs 70–73; ds). Process of gonopore absent.

Female genitalia. Gonocoxites 8 longer than wide; sutural margins juxtaposed at 1 / 3 basal portion, each widely separated and sinuous on the remaining 2 / 3; posterior margins concave; each sutural margin with fringe of setae covering gonapophyses 8 ( Figs 74–75; gc 8). Gonapophyses 8 visible, carinated medially ( Figs 74–75; g 8). Laterotergites 8 triangular, longer than wide; each posterior margin acute surpassing tergite 8; each spiracle placed posterior to lateral angle of each gonocoxite 8 ( Figs 74–75; la 8). Gonocoxites 9 trapezoidal, each with 1 + 1 tufts of long setae on disc ( Figs 74–77; gc 9). Each laterotergite 9 digitiform, depressed basally; apex rounded and surpassing tergite 8 ( Figs 74–75; la 9). Segment X rectangular ( Figs 74–75; X). Gonapophyses 9 each 1 + 1 sclerotized areas surrounding chitinellipsen ( Figs 76–77; ch) and 1 + 1 lateral folds reaching posterior margin of chitinellipsen ( Figs 76–77; ch). Chitinellipsen circular ( Figs 76–77; ch). Thickening of vaginal intima tube-like ( Figs 76–77; t vi). Median duct of vesicular area with a sclerotized ring at base ( Figs 76–77; md). Capsula seminalis with three processes ( Figs 76–77; cs).
