† Glaesoconnus unicus sp. n.

(Figs 11, 103–107)

Type material. Holotype: Late Eocene of Europe, Rovno amber: sex unknown; inclusion in elongate, P-shaped piece of amber 19 mm long (Fig. 11), collection number K-5770 (SIZK).

Diagnosis. As for genus, vide supra.

Description. Body (Figs 103–107) elongate, relatively stout and moderately convex, brown; BL 1.01 mm.

Head (Figs 103–107) broadest at eyes, HL 0.15 mm, HW 0.25 mm; vertex and frons together subtrapezoidal and strongly transverse; supraantennal tubercles weakly raised; compound eyes large, strongly convex, oval. Punctures on head fine but distinct, those on vertex (Fig. 106) separated by spaces as wide as 2–3 diameters of punctures; setae (Fig. 106) short, sparse, suberect. Antennae (Figs 103–107) shorter than half BL, AnL about 0.43 mm, with compactly assembled antennomeres but the orientation of specimen makes it difficult to assess shapes of antennomeres, of which scape and pedicel are strongly elongate and flagellomeres except XI seem to be transverse, antennomere XI oval, about twice as long as broad, with rounded apex.

Pronotum (Figs 103–104, 106–107) round, broadest near middle, anteriorly narrowing more distinctly than posteriorly; PL 0.24 mm, PW 0.30 mm; punctures on disc (Fig. 106) small but distinct, separated by spaces 3–5 × as wide as diameters of punctures; setae (Fig. 106) short, sparse and suberect, directed posteromesally.

Elytra (Figs 103–104, 106) elongate oval, moderately convex, broadest in front of middle, EL 0.63 mm, EW 0.48 mm, EI 1.32; setiferous punctures as small as those on pronotal disc, arranged in slightly irregular longitudinal rows (Fig. 106); setae short, sparse, suberect.

Legs (Figs 103, 105–107) moderately long, slender, unmodified.

Etymology. The name unicus was chosen to underline the uniqueness of this species (Latin "only, sole, single, singular, unique").
