glabrous anteriorly; gena mostly glabrous
and finely punctate, with a row of foveae
along anterior side of lateral occipital carina.
Anterior tentorial pits distinct. Clypeo-pleurostomal
sulcus and epistomal sulcus indistinct.
Lateral occipital carina reaching vertex.
Occiput glabrous.
Anterior flange of pronotum glabrous;
submedian pronotal pits distinctly separated
medially. Anterior plate of pronotum densely
punctate and pubescent with a row of foveae
posteriorly. Pronotum dorsomedially distinctly
raised, but lower than mesoscutum;
pronotal crest medially raised medially into
a small, distinct process. Lateral pronotal
carina distinct and reaching pronotal crest
dorsomedially. Lateral surface of pronotum
foveate-reticulate. Dorsal pronotal area glabrous,
reaching to one-fourth of posterior
margin of pronotum. Mesoscutum slightly
arched dorsally, transversely costate with
foveae set in rows. Scutellar sulcus divided
by median longitudinal carina and four
submedian equally strong carinae; mesoscutellum
foveate-reticulate, with posterior margin
rounded in dorsal view. Mesopleural
triangle well defined ventrally by a smoothly
curved carina. Median mesopleural impression
percurrent, without transverse costae;
upper mesopleuron glabrous; lower mesopleuron
glabrous, and bordered by a distinct,
straight carina ventrally. Metepisternum longitudinally
costate and devoid of pubescence
in upper part, conspicuously pubescent ventrally.
Propodeum areolate-reticulate; lateral
propodeal carina percurrent and distinctly
diverging posteriorly; median propodeal area
rugose; median longitudinal carina distinct
only anteriorly, ending at anterior transverse
carina. Rs+M of forewing arising from
anterior third of basal vein. Marginal cell
3.4 times as long as wide and 1.5 times as
long as submarginal cell. Bulla on Sc+R 1
absent. Marginal cell 2.7 times as long as
wide and 1.2 times as long as submarginal
cell.
Abdominal petiole as long as wide in
lateral view; lateroposterior margin curved
to form a wide angle. Relative length of T3–
8: 2.0:1.0:1.1:4.2:0.9:1.6; T3–5 glabrous; T6
glabrous anteriorly, and densely punctate
and pubescent dorsoposteriorly; T7 coarsely
punctate with distinct pubescence anteriorly
and finely, densely punctate posteriorly; and
T8 coarsely punctate/foveate with pubescence.
Legs sparsely pubescent except metatibia
and metatarsomeres densely so. Apical
teeth of metatibia short, stout, and blunt
apically. 1mt/2–5mt 5 0.90.
MALE: Unknown.
The new species is most easily distinguished
from all other species of Paramblynotus
by having a triangular area in the
middle of the posterior part of vertex with
fine, longitudinal carinae, and is further
separated from all other species of the
ruficollis group by having petiole as long as
wide.
TYPE MATERIAL: HOLOTYPE: R, Malaysia:
N. Borneo, Tawau, Quoin Hill, Forest
Camp (1.3–5 km WSW of Coca Research
Station), 1962-VII-9–20, Y. Mirashima coll.
(BPBM).
DISTRIBUTION: Malaysia: Borneo.
ETYMOLOGY: From Latin, carina, keel,
ridge, and vertex, top. The name refers to the
longitudinally carinate triangular area in
middle of posterior part of vertex

Paramblynotus trisectus Maa, 1962: 126, R; Thailand;
BPBM (HTR).
FEMALE: Length 5.0–6.0 mm. Wings
slightly ferruginous with marginal and submarginal
cells of forewing darker. Body color
is discussed in remarks below.
Vertex heavily foveate-reticulate; gena
densely punctate and foveate (fig. 56). Ocellar
plate well defined by lateral carina, along
which lined large foveae (fig. 56). Antennal
scrobe mainly densely punctate, posteriorly
somewhat longitudinally rugose. Median
frontal carina absent in lower face. Pronotal
crest medially raised into a small, triangular
process. Lateral surface of pronotum foveatereticulate,
with very sparse punctures
(fig. 57). Mesoscutum transversely carinate
with foveae set in between (fig. 58). Mesoscutellum
sloped posteriorly (fig. 58). Lateral
propodeal carina smoothly raised medially
(fig. 60), arch-shaped in lateral view. 1mt/2–
5mt 5 0.77.
MALE: Length about 4.5 mm, otherwise
similar to female.
