Description. Male. Body dark brown with yellow spots, lines and patches. Length of the body 3.0- 3.12 mm, width 1.32-1.34 mm.

Head dark brown with four pale dots on vertex and frons and a W-shaped pale line above clypeus. Clypeus, maxillary and mandibulary plates brown with small pale patches. Length of head 0.45 mm, width 0.70 mm, diameter of eye 0.20 mm. First antennal segment pale at base, then pale brown, apical part covered with pale and brown setae. Second segment pale brown at base and apex, covered with dense, dark setae. Third and fourth segments thin, dark, covered with long brown and short pale setae. Lengths of first to fourth antennal segments in mm: 0.30: 0.64: 0.44: 0.42. First rostral segment chestnut; remaining segments dark brown.

Pronotum. Anterior lobe of pronotum dark brown, only the anterior margin with a thin, yellow stripe, posterior lobe dark brown, sometimes slightly tinged with red, with six short, pale, longitudinal stripes. Length of pronotum 0.52 mm, length of anterior margin 0.55 mm, lateral margins 0.50 mm, posterior margin 1.05-1.07 mm.

Mesoscutum dark brown, paler on sides. Scutellum dark brown, shining, with pale yellow apex.

Hemelytra dark brown, with numerous small, pale yellow spots and patches. Medial fracture, R + M, margin of corium and claval suture pale yellow apically. Clavus dark brown with numerous small spots; margins along scutellum pale. Clavus brown, pale at apex, with a pale transverse line along costal fracture. Membrane dark grey; venation dark; major cell rounded; minor cell indistinct in all available specimens.

Ventral surfaces. Body dark brown ventrally, coxae and trochanters dark brown; femora brown with a paler patch near the apical part, apex sometimes tinged with red. Tibiae brown, darker than femora, with a contrasting pale, broad ring near the apical part ( Fig. 1 ); tarsi pale brown.

Male genitalia. Left paramere with a small sharp process; right paramere slender ( Figs. 2- 3 ). Phallus membranous, with sclerotized spiculi ( Fig. 4 ).

Female. Similar to male. Length of the body 3.12 mm, width 1.52 mm. Length of head 0.50 mm, width 0.75 mm, diameter of eyes 0.17 mm. Lengths of antennal segments in mm: 0.30: 0.55: 0.57 (fourth segment broken in the specimens examined). Length of pronotum 0.62 mm, length of anterior margin 0. 57 mm, lateral margins 0.52 mm, posterior margin 1.12 mm.

Female genitalia. Vagina particularly complex ( Fig. 5 ), including numerous sclerites. Parieto-vaginal rings difficult to see in dorsal view, classical in latero-dorsal view ( Fig. 6 ). Posterior margin (PmPv) of each ring narrow, its outer extremity in dorsal view partially hidden by a wide sclerites (S1). Latero-outer margin (LoPv) narrow, probably forming wide sclerites S1 posteriorly. Dorsal margin (Dpv) narrow, narrower on its inner part. Latero-inner margin (LiPv) relatively wide, sigmoid, partially hidden in dorsal view by a sclerite (S2) also partially obscuring the bulb. Dorsal wall (Dw) large, with two fields (F) of small teeth. Lateral oviducts (Ol) elongated. Dorsal wall lined by a complex of sclerites S3, partially hidden in dorsal view by parieto-vaginal ring and sclerites S2. A short and narrow sclerite S 4 in dorsal view seems to join together the sclerites S2. Anterior or seminal sac (Ss) large, lacking sclerites. Anterior margin of dorsal labiate plate (AmDLP) very wide. Posterior wall ( Fig. 7 ) very unique in shape. Inter-ramal sclerites (= A structures, AS) transversally subdivided by a membranous area (MA). Inter-ramal sclerites not subdivided longitudinally by a median process (= B structure), in the so-called dorsal part of the wall (below on our Fig. 7 ) but subdivided in the so-called ventral part (arrow). Inter-ramal lobes (= E structures, ES) large. Lateral lobe (= H structure) absent.

Etymology. This species is dedicated to Jacek Hulinka, a friend of the senior author.

Distribution. West Malaysia.
