Etymology.
The species epithet of the new species is derived from Latin,
longe
, long, and
petiolum
, petiole, referring to the longer petiole of the species in comparison with the other known species of the
punctulatus
group.
Diagnosis.
Paramblynotus longipetiolus
is very similar to
P. hainanensis
, and
P. anjiensis
, but differs by having the median frontal carina continuous from the anterior ocellus to the epistomal sulcus and distinctly raised into a triangular lamella between the antennal sockets;, and the mesoscutellum posteriorly not raised or projected into two triangular processes.
Description.
FEMALE (
holotype
). Body length
3.9 mm
. Fore wing (
Fig. 21
) with Rs+M of arising from slightly anterior third of basal vein, marginal cell 2.8 times as long as wide and 1.2 times as long as submarginal cell.
Coloration. Head, antenna, mesosoma, and metasoma dark brown; legs yellow brown. Fore wing clear, with a deep ferruginous macula covering marginal cell and part of third cubital cell behind marginal cell.
Head (
Figs. 17–18
). Vertex foveate-reticulate. Eye distinctly extended laterally beyond outer margin of gena. Ocellar plate distinctly raised, foveate-reticulate, defined laterally by carina, with a row of large, superficial foveae along lateral carina. Median frontal carina continuous from anterior ocellus to epistomal sulcus, distinctly raised into a triangular lamella between antennal sockets. Dorsal frons foveate laterally; antennal scrobe glabrate, deeply depressed, densely punctate, foveate posteriorly. Gena foveate-punctate reticulate, horizontally costate posteriorly. Ventral frons foveate, punctate-recticulate; clypeus punctate and longitudinally carinate; anterior tentorial pits distinct; clypeo-pleurostomal sulcus, epistomal sulcus forming smoothly curved arch. Lateral occipital carina reaching vertex. Occiput shining smooth with long setae along the edge.
Mesosoma (
Figs. 19–20
). Anterior flange of pronotum finely transversely striate; submedian pronotal depressions separated medially. Anterior plate of pronotum densely punctate dorsomedially. Pronotum dorsomedially slightly raised, but distinctly lower than mesoscutum; pronotal crest not raised medially. Lateral pronotal carina distinct, reaching pronotal crest dorsomedially. Lateral surface of pronotum foveate-reticulate. Dorsal pronotal area glabrate, present only along anterior third of posterior margin of pronotum. Mesoscutum strongly arched dorsally, transversely costate with superficial foveae set in rows and a curved longitudinal carina. Scutellar sulcus divided by a median carina; mesoscutellum posteriorly not raised, not projected into two triangular processes. Axillar area without distinct pubescence. Mesopleural triangle conspicuously pubescent and well defined ventrally by smoothly curved carina. Median mesopleural impression percurrent, glabrous, with transverse costae. Upper mesopleuron glabrous. Lower mesopleuron glabrous, conspicuously pubescent ventrally. Metepisternum areolate-reticulate in upper part, conspicuously pubescent ventrally. Lateral propodeal carina abruptly curved medially; median propodeal area areolate-reticulate; median longitudinal carina percurrent, crossed by submedian transverse carina.

, female: 17, Head (frontal view); 18, Occiput (dorsal view); 19, Mesosoma (lateral view); 20, Mesosoma (dorsal view); 21, Wings; 22, Metasoma (lateral view); 23, Antenna; 24, Tibia and tarsus of hind leg.
Petiole 1.8 times as long as wide in lateral view. Tergum 8 exposed; relative length of T3–8: 2.0:1.0:1.3:1.4:1.7:0.3; T3–5 glabrous; T6–8 densely punctate; T6 and T7 with anterior row of sparse pubescent; T8 glabrous. Apical teeth of metatibia long, slender, pointed apically.
MALE. Length
3.5 mm
.
Distribution.
China
:
Zhejiang Province
(Oriental region);
Henan Province
(Palearctic region). It seems likely that this new species may eventually be found in the intervening provinces of
Jiangxi
,
Anhui
,
Jiangsu
and
Hubei
.
