? Euconnus sp. 2

(Figs 27, 189–192)

Material studied. Late Eocene of Europe, Rovno amber: sex unknown; inclusion in subquadrate piece of amber 10 mm long (Fig. 27), collection number K-24859 (SIZK).

Description. Body (Figs 189–192) elongate, relatively stout and strongly convex, nearly black; BL 1.55 mm.

Head (Figs 189–192) broadest at eyes, HL 0.30 mm; shape of vertex and frons difficult to assess but both convex (Fig. 192); tempora seem about as long as eyes or slightly longer (Fig. 192). Punctures and setae on frons and vertex poorly visible, setae seem sparse and suberect (Fig. 192), tempora (Fig. 192; tm) covered with sparse thick bristles. Antennae (Figs 189–192) slightly shorter than half BL, AnL 0.75 mm, scape and pedicel strongly elongate, shapes of most of flagellomeres, especially distal ones, difficult to assess, but antennae seem to have indistinctly demarcated club composed of antennomeres VIII–XI.

Pronotum (Figs 189–192) of unclear shape; PL 0.38mm; anterior margin seems arcuate; posterior margin shallowly bisinuate, shapes of pronotal corners and lateral margins difficult to assess; base of pronotum with short but distinct sublateral carinae (Fig. 192; slc) and one (inner) pair of antebasal pits (Fig. 192; abp). Punctures on pronotal disc (Figs 191–192) small but distinct, separated by spaces 3–4 times as wide as diameters of punctures; setae (Figs 101–192) short, sparse, suberect; sides of pronotum with thick bristles.

Elytra (Figs 189–192) elongate oval, strongly convex, EL 0.75 mm; punctures and setae similar to those on pronotum (Figs 191–192). Scutellum not visible between elytral bases.

Legs (Figs 189–192) moderately long, slender, unmodified.

Remarks. This specimen resembles many extant species of Euconnus, but key generic characters, located mostly on the ventral side of pterothorax, are not visible. If this is Euconnus, then certainly not conspecific with the two specimens described above.
