Material examined: Iran, Guilan Province: Rasht (37°11′45′′N 49°38′25′′E), 17♁ 40♀, light trap, 15.V.2021 ; Sangar (37°07′26′′N 49°43′50′′E), water inlet channel to the dam; 14♁ 30♀, sweeping, 06.VI.2021 ; Dasht-e-Veyl , near brook (36°50′47′′N 49°35′00′′E), 10♁ 5♀, sweeping, 18.VI.2022 .

Diagnosis: Body elongate and narrowed toward posterior third; hemelytron light-brown with an irregularlyshaped dark mark and with short unevenly arranged hairs; protonum wider than head, longer than median head length; eyes black or black with golden spots ( Fig. 8A ). Metaxyphus narrow, short and triangular, with apex narrowly rounded ( Fig. 8B ).

Males: pala with four long setae dorsally; ventrally, palmar area with single short seta distally and a few scattered setae in the middle, ca. 16 setae in mesial row and ca. 11 setae in lateral row, lateral row setae more pronounced than those of mesial row; palar claw broadened distally, apex rounded ( Fig. 11D ). Median lobe of sternum VII broad basally, narrow apically, with pointed apex and four long setae ( Fig. 9A ). Strigil present. Prestrigilar flap on segment V (as in Fig. 9B ). Free lobe of tergum VIII broad, mesial angle rounded with ca. 5 short setae distributed submarginally and lateral angle slightly produced with ca. 18 long setae ( Fig. 9C ). Left paramere: shaft flattened, parallel sided, apex with a noticeable ridge at the top; basal lobe long, tongue-shaped ( Fig. 9D ). Right paramere: proximal part of shaft widened, distal fourth curved, apex narrowly rounded; base with a distinct hump on mesial side, near base of shaft; pars stridens processus located on marginal part of the base ( Fig. 9E ).
