2007 LIU ET AL.: REVISION OF PARAMBLYNOTUS (HYMENOPTERA) 65
setigerous punctures in a row; T7 punctate
with a few setigerous punctures in a row. T8
slightly exposed beneath T7. Front and
middle legs sparsely punctate with pubescence;
hindlegs sparsely punctate with pubescence
except metacoxa dorsally glabrous and
metatibia and metatarsomeres densely punctate
with pubescence. Apical teeth of metatibia
small, thin, and pointed apically. 1mt/2–
5mt 5 0.55.
MALE: Length 2.2–3.0 mm. Antenna 14-
segmented. Tergum 5 expanded both dorsally
and ventrally, but more so ventrally.
Paramblynotus jacksoni is similar to P.
cameroonenesis and P. rwandensis, but it
differs from the latter two species in
(1) median frontal carina not distinctly
extending in lower face, (2) head and
mesosoma black, and (3) Rs and Rs+M veins
of forewing distinct and brown. It further
differs from P. cameroonenesis in having
longer petiole, and from P. rwandensis in
having median propodeal area glabrate.

the collector.
Paramblynotus carinatus, new species
FEMALE:
Length 3.2 mm. Body entirely
dark brown; legs yellow. Wings clear.
Antenna 13-segmented; flagellum not distinctly
thicker apically; median flagellomeres
constricted proximally and apically. Vertex
foveate-reticulate with distinct longitudinal
carinate component. Eye prominent, distinctly
extended laterally beyond outer margin of
gena. Ocellar plate raised and defined laterally
by a carina; lateral carina of ocellar plate
meeting medially above antennal sockets and
lined by a row of irregular foveae along
interior side; ocellar plate foveate; median
frontal carina distinct in lower face, reaching
to epistomal sulcus and bifurcated posteriorly
to delimit a glabrous triangular area
beneath anterior ocellus. Upper face glabrate
laterally and antennal scrobes glabrous;
antennal scrobe defined by carina laterally.
Lower face coarsely foveate-reticulate with
pubescence. Anterior tentorial pits distinct.
Clypeo-pleurostomal sulcus and epistomal
sulcus almost form a smoothly curved arch.
Clypeus longitudinally carinate anteriorly,
glabrous in the middle, and foveate-rugose
posteriorly. Gena coarsely foveate-rugose.
Lateral occipital carina almost meeting eye
dorsally. Occiput glabrous.
Anterior flange of pronotum glabrate.
Anterior plate of pronotum glabrous and
sparsely punctate anteriorly. Pronotum dorsomedially
not distinctly raised; pronotal
crest medially not raised into a process.
Lateral pronotal carina distinct, meeting
pronotal crest dorsomedially. Lateral surface
of pronotum foveate-reticulate dorsolaterally
and longitudinally carinate lateroventrally.
Dorsal pronotal area glabrous, reaching end
of posterior margin of pronotum. Mesoscutum
distinctly arched dorsally and foveatereticulate
with indistinct transverse costae.
Scutellar sulcus divided by a median longitudinal
carina and two submedian longitudinal
carinae; mesoscutellum foveate-reticulate
and sloped posteriorly; posterior margin
rounded in dorsal view. Mesopleural triangle
ventrally well defined by smoothly curved
carina and with white pubescence. Upper
mesopleuron, including speculum, glabrous;
median longitudinal impression percurrent
with evenly distributed transverse carinae;
lower mesopleuron glabrous and pubescent
ventrally. Metepisternum foveate-reticulate
and nude above, with an elevated glabrous
area medially, and conspicuously pubescent
ventrally. Propodeum areolate-reticulate; lateral
propodeal carina percurrent and distinctly
curved medially. Median propodeal
area glabrate to rugulose; median longitudinal
carina percurrent, a transverse carina
present anteriorly, and two submedian longitudinal
carinae present posterior to transverse
carina. Rs+M of forewing nebulous,
arising from middle of basal vein. Marginal
cell 2.4 times as long as wide. Bulla on Sc+R 1
absent.
Abdominal petiole 0.6 times as long as
wide in lateral view and glabrate dorsally.
