2007 LIU ET AL.: REVISION OF PARAMBLYNOTUS (HYMENOPTERA) 113
dially raised, slightly higher than mesoscutum;
pronotal crest gradually raised medially
into a small peak. Lateral pronotal carina
distinct, reaching pronotal crest dorsomedially.
Lateral surface of pronotum foveatereticulate
with fine oblique striate component
and conspicuously pubescent. Dorsal pronotal
area superficially transversely striate,
present only along anterior third of posterior
margin of pronotum. Mesoscutum flat dorsally
and transversely costate with superficial
foveae set in rows. Scutellar sulcus divided by
a median longitudinal carina and four submedian
longitudinal carinae. Axillar area
with conspicuous pubescence extended to
cover lateral part of scutellar sulcus. Mesoscutellum
foveate-reticulate; posterior margin
raised and projected posteriorly into two
apically rounded processes. Mesopleural triangle
conspicuously pubescent and well defined
ventrally by a smoothly curved carina.
Median mesopleural impression percurrent
and glabrate; upper mesopleuron glabrous;
speculum sparsely punctate; and lower mesopleuron
glabrous and pubescent. Metepisternum
longitudinally carinate-rugose in upper
part, conspicuously pubescent ventrally.
Lateral propodeal carina percurrent, strongly
raised dorsolaterally into a large, laterally
inclined lobular process with very dense
pubescence; median propodeal area finely
pubescent with a complete median longitudinal
carina crossed by submedian transverse
carina. Rs+M of forewing arising from
anterior third of basal vein. Marginal cell
4.0 times as long as wide and 1.8 as long as
submarginal cell. Bulla on Sc+R 1 absent.
Petiole 0.56 times as long as wide in lateral
view. Tergum 8 distinctly exposed; relative
length of T3–8: 1.5:1.0:1.1:1.9:1.0:1.1; T3–4
glabrous with a few setigerous punctures; T5
punctate dorsolaterally, punctures coarse and
sparse anteriorly; T6 with a large patch of
conspicuous pubescence and finely punctate
lateroventrally; T7 with a band of conspicuous
pubescence dorsolaterally and finely
punctate lateroventrally; and T8 pubescent.
Apical teeth of metatibia short and blunt
apically. 1mt/2–5mt 5 1.2.
MALE: Unknown.
Paramblynotus chrysochaites and P. rufipes
are unique in the punctulatus group in
(1) scutellar sulcus divided by several more
or less equal longitudinal carinae into several
foveae, (2) T8 of female metasoma distinctly
exposed, (3) axillar area with conspicuous
hair tuft, (4) T6–8 with conspicuous patch of
long, golden hairs, and (5) apical teeth of
metatibia short and blunt apically. In fact,
they are more like the species of the ruficollis
group in terms of these characters. However,
they differ from the ruficollis group by the
following characters: pronotal crest raised
into a conspicuous peak anteromedially and
mesoscutum flat dorsally. The species is
further distinguished from P. rufipes in
having pubescence of axillar area extended
to cover lateral part of scutellar sulcus;
mesoscutellum with a distinct emargination
posteriorly and that posterior projection
separated into two lobular processes; pubescence
on pronotum and T6–8 very dense and
long so that sculpture of the body parts is
barely visible; the patch of pubescence on
T6–8 covers posterior third of postpetiolar
metasoma; and T6 distinctly longer than T3.

ETYMOLOGY: From Greek, chryso, gold,
and chaites, long hairs, referring to the
conspicuous and golden-tinted body pubescence
of the species.
Paramblynotus rufipes, new species
FEMALE:
Length 6.0 mm. Body almost
entirely black except metasoma anteroventrally
red brown. Antenna red brown. Legs
red brown except metatarsi black. Wings
transparent and slightly tinted. Body pubescence
conspicuous and golden-tinted.
Antenna 13-segmented; flagellum filiform,
not widened apically. Vertex foveate-reticulate
with dense pubescence. Eye prominent
and distinctly extended laterally beyond outer
margin of gena. Ocellar plate raised,
foveate-reticulate, and defined laterally by
distinct carina lined by a row of large foveae;
a small glabrous triangular area present
beneath anterior ocellus. Median frontal
carina only present as a raised lamilate
process, semicirclar in lateral view and
