Paramblynotus cheni , new species

FEMALE: Length 3.5 mm. Body entirely dark brown except metasoma ventrally and legs brown.

Antenna 13-segmented; flagellum filiform. Vertex foveate-reticulate. Eye prominent and distinctly extended laterally beyond outer margin of gena. Ocellar plate slightly raised, foveate-reticulate, and defined laterally by weak carina. Median frontal carina simple, reaching to level of lower margin of eye. Upper face, including antennal scrobe, foveate to coarsely punctate; antennal scrobe slightly depressed, with longitudinal rugosity, and defined by carina laterally. Gena foveatereticulate. Lower face and clypeus foveatereticulate; anterior tentorial pits small. Lat- eral occipital carina reaching posterior part of vertex. Occiput glabrous.

Anterior flange of pronotum glabrous; submedian pronotal depressions separated from each other medially. Anterior plate of pronotum glabrous, finely punctate dorsomedially. Pronotum dorsomedially raised, slightly 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 almost to end of posterior margin of pronotum. Mesoscutum strongly arched dorsally and foveate-reticulate. Scutellar sulcus divided by a single median longitudinal carina. Mesoscutellum foveatereticulate; posterior margin rounded in dorsal view. Axillar area without distinct pubescence. Mesopleural triangle pubescent, well defined ventrally by a smoothly curved carina. Median mesopleural impression percurrent and transversely costate; upper mesopleuron glabrous except finely punctate anteriorly; lower mesopleuron glabrous, conspicuously depressed along ventral margin, and sparsely pubescent ventrally. Metepisternum areolate-reticulate in upper part and pubescent ventrally. Lateral propodeal carina percurrent and raised throughout into a ridge; median propodeal area glabrate; median longitudinal carina present prior to submedian transverse carina. Rs+M of forewing arising from middle of basal vein. Marginal cell 2.5 times as long as wide and slightly longer than submarginal cell. Bulla on Sc+R 1 absent.

Petiole 1.13 times as long as wide in lateral view. Tergum 8 not exposed; relative length of T3–7: 2.0:1.0:1.3:2.0:1.1; T3–4 glabrous; T5–6 densely punctate; T7 densely punctate and with row of sparse pubescence anteriorly. Apical teeth of metatibia long, slender, and pointed apically. 1mt/2–5mt 5 0.72.

Paramblynotus cheni is similar to P. isolatus , P. nipponensis , P. punctulatus , but it differs from the latter in the following charaters: antennal scrobe slightly depressed and with longitudinal rugosity; median frontal carina distinct and extended in lower face beyond the lower margin of eye; longitudinal mesopleural impression distinctly transverse-

ly costate; petiole longer than width; and T6 of female strongly expanded lateroventrally with posterior margin parallel with the posterior margin of T5.
