Ранее описанный по самке род Eocencnemus Simutnik с типовым видом E. sugоnjaevi Simutnik из ровенского янтаря, характеризуется архаичным строением брюшка с вершинным расположением пигостилей, отсутствием замыкающих щетинок на дистальном крае голой косой полоски ((linea calva), 3-зубыми мандибулами, длинными жилками передних крыльев. К этому роду предварительно отнесен и вновь обнаруженный самец, также обладающий всеми этими признаками. Новый вид отличается от Е. sugonjaevi более короткой постмаргинальной жилкой передних крыльев и отсутствием парапсидальных борозд (notauli).

A Description of the Encyrtid Male (Hymenoptera, Chalcidoidea, Encyrtidae) with Archaic Structure of
Metasoma from Rovno Amber. Simutnik S. A., Perkovsky E. E. — Eocencnemus vichrenkoi Simutnik,

This paper is the third communication on the finds of encyrtid wasps in the Rivne amber. In the two
previous papers, two new genera and species were described based on females: Eocencyrtus Simutnik (Ñèìóò-
íèê, 2001) è Eocencnemus Simutnik (Ñèìóòíèê, 2002) those probably belong to different subfamilies of
Encyrtidae. A new male described below is provisionally attributed to the genus Eocencnemus Simutnik.
All the examined samples of amber were originally collected either in the Klesov or Dubrovitsa amber
deposits in the north of Rivne (formerly Rovno) Region (Ukraine) (Perkovsky et al., 2003 a). The age of
this amber is estimated as Late Eocene (Perkovsky et al., 2003 b). The type material is deposited in the
collection of I. I. Schmalhausen Institute of Zoology, National Academy of Sciences of Ukraine (Kyiv).

Head somewhat wider than high (ratio 34 : 27); width of vertex 0.21 mm; vertex,
frons and face with shallow cellular sculpture; dorsal margin of occiput acute; ocelli
large, forming obtuse triangle; distance between posterior ocellus and eye margin more
than between ocellus and occipital margin; distance between ocellus and occipital mar-
gin slightly less than ocellus diameter; compound eye vertical diameter approximately
as long as intermalar distance; facial cavity deep, sharply emarginated, its dorsal mar-
gin almost reaching anterior ocellus; antennal grooves slightly below level of eye ven-
tral margin; mandible tridentate; scapus short (0.15 mm), slightly widened, all flagel-
lomeres longer than wide, flattened, densely pubescent (fig. 1, 5); clavus three-articu-
late, slightly longer than 2 preceding joints combined, as wide as flagellum.
Mesosoma: pronotum short; mesonotum short setulose, almost smooth, axillae and
scutellum with indistinct microcellular sculpture; scutum as long as scutellum (0.3 mm :
0.3 mm), width unavailable for measuring; mesothoracal pleura smooth, microcellular
sculptured.
Fore wing: wide, not darkened, almost twice as long as wide (1.16 mm : 0.63 mm),
uniformly pubescent; bare oblique stripe (linea calva) without enclosing setulae on dis-
tal margin; fringe short; veins long (fig. 1, 3–4).
Fore tibia with moderately long curved spur; midtibial spur slightly shorter than
first tarsomere. Propodeum short.

biology school teacher.
T a xonom i c a l n o t e s. It is commonly accepted among encyrtidologists to
establish no new species, and certainly no new genera based on males. “Various special
morphological modifications are more expressed in females than in males of [encyrtids],
making determination of species on the basis of males more difficult tha n on females,
and some genera virtually indistinguishable based on this sex” (Òðÿïèöûí, 1989: 23).
We therefore consider erection of another new genus based on the male described above
inexpedient; we assign it to the genus Eocencnemus Simutnik (Ñèìóòíèê, 2002), which
is characterized by an archaic structure of abdomen with the pygostyli apical, no enclos-
ing setulae on the distal margin of the bare oblique stripe (linea calva) on the wing, the
mandibulae tridentate, and veins on the fore wing long (fig. 2, 1–4). The male
described above also possesses all these characters, differing from E. sugonjaevi by the
the pa rapsidial grooves (notauli) absent and the postmarginal vein much shorter (fig. 1,
3 and 2, 1).
The apical position of the pygostyli rarely occurs among recent encyrtids, among
them Quadrencyrtus Hoffer, Eucoccidophagus Hoffer (Òðÿïèöûí, 1989; Ñèìóòíèê,
2002, 2005). Three of the four encyrtid specimens from the Late Eocene Rovno amber
