very reduced. 1mt /2–5mt 5 0.5.
MALE: Unknown.
Paramblynotus distictus is very similar to
P. fraxini and P. kosugii. It can be easily
separated from all other Paramblynotus
species by having a longitudinally carinate
occiput and pronotum raised anteriorly into
a peak, yet lacking apical protuberance of
first metatarsomere. It differs from P. fraxini
and P. kosugii in (1) antennal flagellum
distinctly widened apically, apical flagellomere
two times as wide as medial width of
F1; (2) gena glabrate punctate; (3) mesoscutellum
not projected posteriorly; and (4) body
orange brown entirely.

ETYMOLOGY: From Latin, distinctus,

Paramblynotus fraxinii Yang, 1994
Paramblynotus fraxinii Yang, 1994: 157–164, R;
China: Helongjiang; NWCF (HTR, paratype
2RR).
FEMALE:
Length 4.5 mm. Head, mesosoma,
and antenna black. Legs brown except
coxae black. Metasoma brown. Wings transparent.
Relative size of abdominal T3–T7:
1.9:1.0:1.1:2.4:0.9. Metatarsomere 1mt/2–5mt
5 0.95.
MALE: Unknown.
Paramblynotus fraxinii is most similar to
P. kosugii, but it differs from the latter in
(1) mesoscutellum without transverse inflection
before the posterior projection, and
rounded posteriorly in dorsal view; (2) lateral
propodeal carina strongly raised anterodorsally
into a lobular process; and (3) size
smaller. An additional character to separate
P. fraxinii from most other species of
Paramblynotus is that the female antenna is
12-segmented.
MATERIAL EXAMINED: 1R (paratype),

Paramblynotus kosugii Watanabe and Sakagami,
1951: 129, =; Japan: Honshu; EIHU (HT=,

MALE: Length 6.0 mm. Head, mesosoma,
and antenna black. Legs brown except
coxae black. Metasoma brown. Wings transparent.

FEMALE:
Unknown.
Paramblynotus kosugii is most similar to
P. fraxinii, but it differs from the latter in
(1) mesoscutellum with an inflection prior to
the posterior projection, and truncate posteriorly
in dorsal view; (2) lateral propodeal
carina not raised anterodorsally into a lobular
process; and (3) size distinctly larger.

Paramblynotus borneanus (Weld, 1922)
Paribalia borneana Weld, 1922: 326, =R; Borneo;
USNM (HTR, paratype =).
Paramblynotus borneanus (Weld) Ronquist, 1994,
combination.
FEMALE: Length 4.8 mm. Head and
thorax black to dark brown; antennae, legs,
and metasoma reddish brown. Head, mesosoma,
and legs densely pubescent; mesopleural
triangle and axillar area with conspicuous
pubescence. Wings entirely
transparent.
Vertex foveate-reticulate. Eye extended
laterally beyond outer margin of gena.
Ocellar plate distinctly raised, mostly foveate-reticulate,
and defined laterally by carina
lined along interior side with a row of large
foveae. Median frontal carina present between
antennal sockets and simple. Upper
face foveate-rugose laterally; antennal scrobe
distinctly depressed, glabrate with sparse
punctures and pubescence, and defined by
carina laterally. Gena glabrate with dense
punctures and pubescence; lower face and
clypeus foveate/punctate-reticulate with
