† Rovnoscydmus sp. specimen 7 (Figs 20, 151–154) Material studied. Late Eocene of Europe, Rovno amber: sex unknown; inclusion in subtriangular, irregular piece of amber 23 mm long (Fig. 20), collection number K-3037 (SIZK). Description. Body (Figs 151–154) elongate, slender and relatively strongly convex, moderately light brown; BL 0.95 mm. Head (Figs 151–154) broadest at eyes, HL about 0.15 mm, HW 0.20 mm; vertex strongly transverse; frons not visible; compound eyes large, strongly convex, oval; length of tempora in relation to eyes not possible to assess. Punctures and setae on dorsum of head poorly visible. Antennae (Figs 151–154) much shorter than half BL, AnL 0.35 mm, antennal club indistinctly demarcated; antennomeres I–II strongly elongate, shapes of proximal flagellomeres difficult to assess, antennomeres VIII–X about as long as broad, XI much shorter than IX–X combined, about 1.2 × as long as broad, with rounded apex. Pronotum (Figs 151, 153) slightly elongate, broadest near anterior fourth (but very indistinctly narrowing posteriorly); PL 0.25 mm, PW 0.24 mm; punctures and setae on disc poorly visible, setae on sides of pronotum replaced by distinct thick bristles (Fig. 153). Elytra (Figs 151, 153) elongate oval, broadest site not possible to define, EL 0.55 mm, EW 0.38 mm, EI 1.47; punctures (Fig. 153) fine but distinct, separated by spaces 2–3 × as wide as diameters of punctures; setae (Fig. 153) short, sparse and nearly recumbent. Legs (Figs 151–154) moderately long, slender, unmodified. Remarks. This specimen, although relatively well exposed, is unremarkable and difficult to identify as conspecific with any other inclusion of Rovnoscydmus.
