Head. Eyes somewhat removed from pronotal collar (Fig. 1A); vertex convex medially, sloping onto posterior margin of vertex and frons (Figs 1C, E); antennomeres I and II nearly cylindrical, antennomere I weakly narrowed basally, antennomere II weakly broadened toward apex (Figs 1A, C, E); labium reaching hind coxae (Fig. 1B); segment I subdivided near medial part (Figs 1B, C); segment II subdivided near apex (Fig. 1B). Thorax. Anterior lobe of pronotum strongly convex, large, occupying two thirds of pronotum (Figs 1A, B, E); humeral angle thin and relatively long; posterior margin strongly concave (Figs 1A, G). Mesoscutum and scutellum. Mesoscutum weakly convex; scutellum flat (Fig. 1G). Thoracic pleura. Scent gland evaporative area of metepisternum narrow, situated posteriorly. Legs. Tarsus two segmented (Fig. 1I); pretarsal claw with subapical tooth (Fig. 1J). Abdomen. Female genitalia. Genital chamber membranous (Figs 2A, B); sclerotized rings paired, relatively large, subellipsoid, situated laterally (Fig. 2A); dorsal sac of genital chamber membranous, relatively broad, situated laterally (Fig. 2A); lateral oviducts removed from each other, conflating into dorsal sac (Fig. 2A); ovipositor thin; gonapophyses 8 connected by distinct membranous structure along entire length (Figs 2B, D); apices of gonapophyses 8 and 9 obtuse, without any teeth apically (Figs 2D, E); gonapophysis 9 dorsal margin with single tooth medially (Fig. 2E).

Etymology. The new species is named in honor of Sir David Attenborough, whose outstanding documentaries have sparked a love for nature in many people.

Remarks. Fulvius attenboroughi sp. nov. is classified as a member of the anthocoroides -group as characterized by Gorczyca (2002a), Sadowska-Woda et al. (2008), and Wolski et al. (2018) based on the following characters: head, pronotum, thoracic pleura, mesoscutum and scutellum with net-like sculpturation based on microsetae (Figs 1F, G) (Wolski et al. 2018: figs 41–43; Gorczyca et al. 2020: figs 1A, C), second tarsomere not subdivided medially, subapical tooth present (Fig. 1J) (Wolski et al. 2018: figs 45–46; Gorczyca et al. 2020: figs 3A, B); membranous structure between the gonapophyses 8 present (Figs 2B, D) (Gorczyca et al. 2020; figs 5C, D). The new species is most similar to Fulvius carayoni Pluot-Sigwalt & Chérot, 2013, F. kajae Gorczyca, 2000, F. kerzhneri Gorczyca, 2000, and F. webbi Gorczyca, 2000 in sharing the yellow stripes along hemelytra (Fig. 1A; Pluot-Sigwalt & Chérot, 2013). It can, however, be easily distinguished by the convex vertex (Figs 1A, C, E), eyes slightly removed from the pronotal collar (Fig. 1A), the upraised pronotal calli (Figs 1A, B, E), and the broader yellow stripes along hemelytra (Fig. 1A). Within the abovementioned, possibly closely related group of species, F. attenboroughi sp. nov. is most similar to F. kerzhneri in sharing the pale yellow pronotal collar and posterior margin of pronotum and unicolored scutellum (Figs 1A, 3A).
