Paramblynotus isolatus , new species

FEMALE: Length 3.5 mm. Antenna, head, and mesosoma deeply dark brown; metasoma and legs dark brown. Wings evenly, lightly ferruginous.

Antenna 13-segmented; flagellum not widened apically. Vertex foveate-reticulate. Eye prominent and distinctly extended laterally beyond outer margin of gena. Ocellar plate distinctly raised, glabrate anteriorly, foveatereticulate posteriorly, and defined laterally by carina lined by a row of large foveae along interior side. Median frontal carina simple, only present between antennal sockets, and bifurcated posteriorly to seclude a small, triangular glabrous area beneath anterior ocellus. Upper face foveate laterally; antennal scrobe glabrous and sparsely punctate; antennal scrobe deeply depressed and well defined by carina laterally. Gena foveatereticulate anteriorly, glabrate with superficial foveae posteriorly, and with a weak vertical carina medially. Lower face and clypeus foveate/punctate-reticulate. Anterior tentorial pits distinct. Clypeo-pleurostomal sulcus and epistomal sulcus form a rectangle above transverse inflexion of clypeus. Lateral occipital carina not reaching vertex. Occiput glabrous.

Anterior flange of pronotum glabrous; submedian pronotal depressions separated from each other medially. Anterior plate of pronotum glabrous and finely punctate with pubescence. Pronotum dorsomedially raised, but lower than mesoscutum; pronotal crest not raised medially. Lateral pronotal carina distinct, not reaching pronotal crest dorsomedially. Lateral surface of pronotum foveate-reticulate mostly and transversely carinate lateroventrally. Dorsal pronotal area glabrate, present along anterior half of posterior margin of pronotum. Mesoscutum distinctly arched dorsally and foveate-reticulate with foveae set in rows between superficial transverse costae. Scutellar sulcus divided by a single median longitudinal carina. Mesoscutellum foveate-reticulate; posterior margin truncate in dorsal view. Axillar area without distinct white pubescence. Mesopleural triangle well defined ventrally by a smoothly curved carina and with white pubescence. Median mesopleural impression percurrent, not transversely costate; upper and lower mesopleuron glabrous, the latter also conspicuously depressed along ventral margin and sparsely pubescent ventrally. Metepisternum areolate-reticulate and devoid of pubescence in upper part, pubescent ventrally, and with a small elevated, glabrous area medially. Lateral propodeal carinae percurrent and subparallel to each other and not raised dorsally into a process; median propodeal area glabrate, median longitudinal carina percurrent crossed by submedian transverse carina. Rs+M of forewing arising from slightly behind middle of basal vein. Marginal cell 3.6 times as long as wide and 1.5 times as long as submarginal cell. Bulla on Sc+R 1 absent.

Petiole 0.58 times as long as wide in lateral view. Tergum 8 almost entirely covered by T7 with tip slightly exposed; relative length of T3–7: 1.25:1.0:1.2:2.3:1.25; T3–5 glabrous; T6 finely punctate dorsomedially and otherwise glabrous; T7 mostly densely, finely punctate, with larger setigerous punctures dorsolaterally. Apical teeth of metatibia long, slender, and pointed apically. 1mt/2–5mt 5 0.70.

MALE: Unknown.

Paramblynotus isolatus is similar to P. nipponensis and P. punctulatus , but it differs from P. punctulatus in lateral propodeal carina not raised dorsally into an almost triangular process, and it differs from P. nipponensis in (1) antennal flagellum not widened apically, (2) scutellar sulcus divided by a single median longitudinal carina,

(3) antennal scrobes entirely glabrous with fine punctures, (4) gena glabrate posteriorly, and (5) mesoscutellum truncate posteriorly in dorsal view.

TYPE MATERIAL: HOLOTYPE: ♀, American Samoa: Tutuila , Mulinnuu, 1963-XII-8, T.C. Maa coll. ( BPBM).

ETYMOLOGY: From Latin, isolatus , detached. The name refers to the relative geographic isolation of the type locality.
