Diagnosis. Recognized by its relatively small size among congeners; grayish brown dorsum with pale brown ventral surface, anterior pronotum, scutellum and lateral margin of hemelytron ( Figs 3E–F View Fig ); uniformly chocolate brown labium; pale legs with narrowly infuscate apex of metafemur and base of metatibia; and unique shape of vesica ( Figs 6J View Fig , 8C View Fig , 18D View Fig ), in addition to ratio of vertex in female greater than that of male.

Description. Body grayish brown, parallel-sided, relatively small (6.6–7.6 mm in total length); dorsal surface weakly shining, with uniformly distributed, pale, simple, semierect setae ( Figs 3E–F View Fig , 17A View Fig ). Head chestnut brown, relatively shining; vertex and frons sometimes pale along inner margin of eye; vertex 0.32–0.34 (J) / 0.30–0.32 (♀) times as wide as head across eyes. Antenna pale brown; extreme apex of segment I dark brown; segment II with dark base and apical 1/4–1/3; basal 2/5 of segment III and basal 1/4 of IV whitish brown. Labium uniformly shiny chocolate brown, slightly exceeding apex of metacoxa ( Fig. 17B View Fig ). Pronotum brown, more or less darkened on calli and posterior disk, with creamy yellow collar and posterior margin; pleura uniformly pale brown; metathoracic scent efferent system as in Fig. 17C View Fig ; mesoscutum and scutellum yellowish white; mesoscutum darkened medially; scutellum with triangular fuscous macula at base and dark apex. Hemelytron grayish brown, with pale exocorium; exocorial serration as in Figs 10D View Fig , 17D View Fig ; cuneus with narrowly yellowish margin and reddish apex; membrane smoky brown. Coxae and legs pale brown, except for darkened apex of metafemur, base of metatibia and tarsomeres II–III; metafemoral plectra as in Figs 10E View Fig , 12F View Fig ; tibial spines reddish brown; pretarsal structures as in Figs 17E–F View Fig . Abdomen pale brown. Male genitalia ( Figs 6H–K View Fig , 8A, C View Fig , 18A–E View Fig ): pygophore with conical process at base of left paramere ( Figs 6I View Fig , 18A View Fig ); left paramere rather L-shaped, with somewhat narrowed hypophysis ( Figs 8A View Fig , 18C View Fig ); vesical lobal sclerites as in Figs 6J View Fig , 8C View Fig , with an elongate, apically hooked sclerite that is accompanied by dense hair-like processes ( Figs 8C View Fig , 18D View Fig ). Female genitalia ( Figs 18F–I View Fig ): interramal lobe projected at inner margin, with uniformly and densely distributed spinules ( Figs 18G–H View Fig ); dorsal structure densely spinulate laterally ( Fig. 18I View Fig ).

Measurements. See Table 1.

Etymology. Named after the Polish heteropterist, Andrzej [Andzhey] Wolski, my long-time friend and colleague, who conducted fieldwork with me in Indochina (including the type locality of this new species) several times but regrettably passed away in May, 2024; a noun in the genitive case.

Biology. Unknown. All available specimens were captured by UV light trap set at tropical dry forest zone. Distribution. North and central Thailand.
