Efesus trufanovi Simutnik , sp.n.

Figs 1–6 .

MATERIAL. Holotype ♀, №15, ZMUC, 1–4–1970; B. V. Henningsen, Danish amber, late Eocene (deposited in ZMUC). The inclusion is situated close to the surface in a separate clear amber piece (about of 15:11: 6 mm) of irregular coulomb shape.

Syninclusions absent.

DESCRIPTION. Body length, 1.4 mm. Other reported measurements are relative, one micrometer division = 0.014 mm, and are approximate because of optical effects in the amber.

Colour. Body and legs dark, with a silver sheen (possibly due to a thin layer of air surrounding the inclusion), wings hyaline. Head. Relative measurements: head width (dorsal view) 31, frontovertex minimal width 11, anterior ocellus diameter 3, POL 5, distance between apical margin of scrobal depression and anterior ocellus 5.5, pedicel + funicle + clava 30, pedicel 5, clava length 12, width 4.5; other proportions of antenna as in Fig. 6 ; distance between toruli 5, from torulus to eye margin 7. Mesosoma . Mesoscutum length 18, width 29; scutellum length 15, width 17; proportions of veins and setation pattern as in Fig. 4 . Metasoma. Length 40, distance between cercus and apex of Mt8 17.

ETYMOLOGY. The species is named after the zoologist and teacher Gennady Alekseevich Trufanov.
