Type material. HOLOTYPE: J, CZECH REPUBLIC: BOHEMIA: Brdy Mts., Tok Mt.(6249), 49°41′47″N 13°52′38″E, about 830 m a.s.l., Malaise trap, 12.v.2005, Liška leg. PARATYPES: 2 JJ 3 ♀♀, the same data as holotype. The type material is currently in my private collection, which is to be deposited in the National Museum, Prague, Czech Republic. Figures are based on paratypes (J ♀).

Description. Body length 5–7 mm. Ground colour brown to dark brown.

Head. Three orbital bristles; 3–4 frontal bristles; frontal vitta, parafacials, face and genae, scapus and pedicellus brown; orbitals, first flagellomere and posterior part of head dark; arista bare, basally shlightly thickened, one and half longer as first flagellomere; vibrissal callus very conspicuous with 8–10 strong bristles; palpi brown, basally narrow and in apical half enlarged with black and short bristles only.

Thorax. Acrostichal bristles very sparse, four to five dorsocentral bristles (2–3 + 2), two humeral bristles, three intraalar bristles, one presutural bristle, one prealar bristle, two postalar bristles, four scutellar bristles of equal size, two notopleural bristles, one distinct proepisternall bristle, one stigmatical bristle and one katepisternal bristle. Wings fumous with brown veins, crossveins R-M and M-Cu with a dark and wide circular colouration, membrane covered by small and dark microtrichia. Legs completely brown, fore femora dark and only apically brown.

Abdomen. Male. Sternite 3 more or less rectangular and caudally with low projection, sternite 4 oval with two small incisions caudally, lobes of sternite 5 basally wide, caudally very narrowed and pointed with short bristles in middle. All sternites with long, hair-like bristles laterally ( Fig.1 ). Cerci with long, hair-like bristles, surstyli short, more or less straight and with hair-like bristles on their inner side ( Fig. 2 ). Pregonite straight with two apical bristles, postgonite of equal size as praegonite and beak-shaped apically, epiphallus with promotory dorsoapically ( Fig. 3 ).

Female. Sternites 5 and 6 oval, sparsely setose, sternite 7 very small and irregular in shape. Tergite 7 completely divided in two sclerites partly moved ventrally and connected by membrane, with very short setae caudally, sternite 8 wide, pointed caudally and with sparse bristles laterally ( Fig. 4 ).

Etymology. The species is dedicated to the Czech heteropterist Petr Kment (National Museum, Prague).

Habitat. The type series was collected in a Malaise trap located at the edge of a waterlogged forest with Picea albies and of a peat bog; herb layer was with Sphagnum moss and cottongrass and tree layer with birch ca. 3–5 m in height, intermixed individual little spruces 1–3 m in height.
