Description. Male. Body small, covered with long pale and dark setae. Length of the body 3.10 mm, width 1.10 mm.

Head. Dark brown, only the middle part of clypeus, and mandibular and maxillary plates pale yellow, slightly tinged with red, covered with long, pale setae; eyes contiguous with the pronotal collar. Length of head 0.37 mm, width 0.60 mm, diameter of eye 0.17 mm. First antennal segment short, pale brown, tinged with red on the inner side, second segment darker, the apex excepted, covered with short, dense, brown and pale setae, slightly thickened towards the apex. Third and fourth segments thin, dark brown, covered with short fine, pale setae. Lengths of the antennal segments in mm: 0.25: 0.87: 0.62 (fourth segment partly broken). Rostrum pale brown, long, reaching beyond metacoxae.

stysi sp. nov., male. Habitus in dorsal view.

Pronotum. Disk dark brown, covered with dark and pale setae, humeral angles slightly elevated. Length of pronotum (including pronotal collar) 0.42 mm, length of the anterior margin 0.47 mm, lateral margins 0.42 mm, posterior margin 1.0 mm. Scutellum and mesoscutum dark brown but paler than pronotum.

Legs. Femora dark brown, with a paler patch ventrally in the apical part. Tibiae brown, with broad paler rings; tarsi pale, two-segmented, the first segment very short, second segment divided; claws with a distinct subapical tooth.

Hemelytra. Dark brown, covered with long, thick, brown setae and fine pale setae. Basal part of hemelytra, apex of clavus and the area contiguous with the basal part of cuneus pale (Fig. 1). Cuneus uniformly brown, membrane dark grey, venation grey, major cell rounded, minor cell hardly visible.

Ventral surfaces. Body dark brown ventrally, coxae and ostiolar peritreme pale.

Genitalia. Parameres very small, slim, and pointed ( Figs. 2-3 ). Phallus with a small sclerite and several teeth ( Fig. 4 ).

Female. External anatomy. Similar to male but paler, pale areas on hemelytra larger, second antennal segment paler than in male. Tibiae unicoloured, pale. Length of the body stysi sp. nov. Female genitalia (right lobe) in dorsal view.

2.52 mm, width 1.0 mm, length of head 0.47 mm, width 0.69 mm, diameter of eye 0.22 mm. Lengths of antennal segments in mm: 0.25: 1.0: 0.65: 0.55. Length of pronotum 0.47 mm (including pronotal collar), length of anterior margin 0.60 mm, lateral margins 0.50 mm, posterior margin 1.0 mm.

Genitalia. Parieto-vaginal rings large, pear-shaped ( Fig. 5 ). Posterior margin (PmPv) of each ring wide, practically straight. Latero-outer and latero-inner margins (LoPv and LiPv) slightly narrower and convex. Anterior margin (AnPv) narrow, convex. Each ring with a dorso-anterior prolongation (Dap) sensu CHÉROT (2002). Dorso-labiate plate difficult to see, membranous. Dorsal wall (Dw) large, devoid of sclerite. Lateral oviducts stout, short.Anterior sac damaged. Posterior wall membranous, its so-called dorsal margin reinforced.

Differential diagnosis. Fulvius stysi sp. nov. differs from F. subnitens Poppius, 1909 by the darker body coloration, the eyes contiguous with the pronotal collar (Fig. 1), the coloration of the antennal segments, and the shape of parameres ( Figs. 2-3 ).

Etymology. This species is named in honour of our friend Pavel Štys, an outstanding heteropterist.

Distribution. North-eastern Papua New Guinea.
