segments (figs. 32, 33). Median frontal carina
simple and present only between antennal
sockets. Antennal scrobes laterally always
defined by a weak, but distinct carina
(fig. 30). Eye laterally about to reach or
slightly extended beyond outer margin of
gena (fig. 31). Occiput glabrous. Lateral
surfaces of pronotum foveate-reticulate, usually
without secondary transverse costae and
punctures, and not separated dorsomedially
by an extended, less sculptured anterior area.
Lateral pronotal carinae distinct, but not
reaching pronotal crest dorsomedially
(fig. 35). Pronotal crest slightly to strongly
raised dorsomedially, with or without a median
emargination. Dorsal pronotal area, as
defined by dorsal pronotal carina, extended
from pronotal crest posteriorly, always
sculptured and usually reaching end of dorsal
posterior margin of pronotum. Mesoscutum
not strongly convex; predominantly transversely
carinate with only superficial foveae
in between (fig. 35). Mesoscutellum sloped
posteriorly, with or without a distinct posterior
vertical surface, and foveate-reticulate
dorsally. Scutellar sulcus is divided into two
foveae by median longitudinal carina. Axillar
area with distinct, but not conspicuous
pubescence (figs. 34, 35). Mesopleural triangle
ventrally well defined by a smoothly
curved carina. Upper mesopleural area glabrous;
speculum without setigerous punctures.
Median mesopleural impression
straight, almost continuous posteriorly with
the vertical part of the ventral mesopleural
impression, and with multiple, equally
strong vertical carinae. Metepisternum alveolate-reticulate
in upper half and pubescent
ventrally (fig. 35). Wings hyaline; Rs-M
from middle of basalis. Dorsoapical teeth
of metatibia long and bluntly pointed
(fig. 36); first metatarsomere without apical
protuberance. Lateral propodeal carinae
simple, not raised into strong keel or
process; median propodeal area usually
with a median longitudinal carina, which
sometime bifurcates behind the median
transverse carina (fig. 34). T7 of female
metasoma with posterior margin curved
dorsolaterally, distinctly exposing T8, and
T6–8 with sparse coarse punctures with hairs
(fig. 37). T3–8 of male not modified and
subequal in size.
