tion. Dorsal pronotal area transversely costate,
and complete to end of dorsal posterior
margin of pronotum and transversely carinate.
Mesoscutum foveate-reticulate with
foveae set in rows between distinct, transverse
costae. Mesoscutellum foveate-reticulate;
sloping posterolaterally and posteromedially
raised into a low hump. Mesopleural
triangle distinctly impressed and pubescent.
Upper mesopleuron glabrous; speculum glabrous.
Longitudinal mesopleural impression
percurrent with several more or less evenly
distributed transverse costae. Lower mesopleuron
glabrous. Metanotal-propodeal complex,
except upper metepisternum glabrous,
foveate-rugose and densely pubescent. Lateral
propodeal carina percurrent and slightly
curved laterally; median propodeal area
areolate-reticulate.
Abdominal petiole half as long as wide in
lateral view. Relative length of T3–8:
1.7:1:1:2.3:1:1. T4–8 densely finely punctate.
All legs densely punctate with pubescence
except metacoxa dorsally glabrous. Metatibia
apically with four slender, pointed teeth. 1mt/
2–5mt 5 0.75.
DIAGNOSIS: The new species is similar
to P. scaber but it can be distinguished
by its glabrate-foveate gena, narrow and
distinct median emargination of pronotal
crest, foveate-reticulate lateral surface of
pronotum, areolate-reticulate median propodeal
area, and reduced to almost invisible
Rs+M vein of forewing. In comparison,
the latter has gena foveate-rugose, lower
median pronotal crest with a broader and
indistinct emargination, lateral surface of
pronotum foveate-reticulate with broken
oblique carinae, and a distinct Rs+M vein
of forewing.

BIOLOGY: Unknown.
Paramblynotus irkutensis Liu and Kovalev,
new species
FEMALE:
Length 4.5 mm. Body black
entirely, except upper mesopleuron and
speculum and legs dark brown. Wings transparent.
Upper face with finely rugose lateral areas
separated by distinct longitudinal carinae
from the glabrous antennal scrobes. Median
frontal carina short, present distinctly between
antennal sockets until one-fourth of
lower face and continued flattened to clypeus,
and bifurcated posteriorly to delimit
a small glabrous triangular area anterior to
anterior ocellus. Lower face foveate-reticulate.
Clypeo-pleurostomal sulcus and epistomal
sulcus form a smoothly curved arch;
clypeus foveate with pubescence. Gena foveate
with sparse pubescence. Vertex foveatereticulate
and laterally with a few secondary
longitudinal carinae. Occiput glabrous and
sparsely punctate with pubescence.
Anterior flange of pronotum glabrous.
Anterior plate of pronotum before lateral
pronotal carinae densely punctate with pubescence.
Lateral pronotal carina distinct
except dorsomedially. Lateral surface of
pronotum foveate-reticulate. Pronotal crest
distinct and distinctly emarginate medially.
Dorsal pronotal area transversely costate and
complete to end of dorsal posterior margin of
pronotum. Mesoscutum foveate-reticulate
with foveae set in rows between low transverse
costae. Mesoscutellum foveate-reticulate;
sloping posterolaterally and posteromedially
raised into a low hump. Mesopleural
triangle distinctly depressed and pubescent.
Upper mesopleuron glabrous mostly and
punctate anteriorly; speculum glabrous. Longitudinal
mesopleural impression percurrent
with several more or less evenly distributed
transverse costae. Lower mesopleuron glabrous
with sparse pubescence. Metanotalpropodeal
complex mostly foveate-rugose
with dense pubescence and glabrous in upper
metepisternum. Lateral propodeal carina
percurrent and distinctly curved laterally;
median propodeal area areolate-reticulate.
Abdominal petiole half as long as wide
in lateral view. Relative length of T3–8:
1.5:1:1:2:0.8:0.8. T4–8 densely finely punctate;
T6–8 also with a few slightly larger
setigerous punctures. All legs densely punctate
with pubescence except metacoxa dorsally
glabrous. Metatibia apically with four
pointed teeth. 1mt/2–5mt 5 0.60.
DIAGNOSIS: The new species is similar to
P. atratus but it can be easily distinguished by
the following characters: antennal scrobes
