Etymology. The species epithet of the new species is derived from Latin, magnatus , larger, referring to the relatively large size of the species.

Diagnosis. Paramblynotus magnatus is very similar to P. ornatus , but differs in that it has the metasoma dark brown and rest of the body bright brown (two examined specimens also had hind legs and propodeum dark brown); the fore wing with a broad smoky band occupying approximately two thirds along outer and posterior margins, and the hind wing with a broad smoky band occupying distal 3/4 of the wing.

Description. FEMALE (holotype). Length 6.5–8.0 mm. Antenna ( Fig. 31 ). Antenna 13-segmented, flagellum filiform, not widened apically. Fore wing ( Fig. 29 ) with Rs+M arising from middle of basal vein, marginal cell 4.7 times as long as wide and 1.4 times as long as submarginal cell.

Coloration. Head dark brown. Body entirely dark brown. Fore wing and hind wing with broad smoky bands.

Head ( Figs. 25–26 ). Vertex glabrate and foveate-reticulate. Eye prominent and distinctly extended laterally beyond outer margin of gena. Ocellar plate slightly distinctly raised, glabrous and sparsely foveate, defined laterally by weak carina. Median frontal carina simple, reaching to level of ventral margin of eye. Dorsal frons foveate laterally; antennal scrobe glabrous, finely punctate, deeply depressed, well defined laterally by carina. Gena foveate-rugose anteriorly, horizontally costate posteriorly. Ventral frons and clypeus punctate-foveate with distinct transverse rugosity; clypeus anterior to submedian transverse inflexion glabrate-punctate. Anterior tentorial pits distinct. Lateral occipital carina not reaching posterior part of vertex. Occiput glabrous.

Mesosoma ( Figs. 27–28 ). Anterior flange of pronotum transversely striate; submedian pronotal depressions separated medially. Anterior plate of pronotum glabrous, and punctate dorsomedially. Pronotum dorsomedially slightly raised, but distinctly lower than highest point of mesoscutum in lateral view ( Fig. 27 ); pronotal crest slightly raised medially. Lateral pronotal carina distinct, reaching pronotal crest dorsomedially. Lateral surface of pronotum foveate-reticulate. Dorsal pronotal area glabrate, present along anterior half of posterior margin of pronotum. Mesoscutum arched dorsally and foveate-reticulate, with foveae set in rows between transverse costae ( Fig. 28 ). Scutellar sulcus divided by median longitudinal carina. Mesoscutellum foveate-reticulate; posterior margin truncate in dorsal view. Axillar area without distinct pubescence. Mesopleural triangle pubescent, well defined ventrally by smoothly curved carina. Median mesopleural impression percurrent; mesopleuron glabrous; lower mesopleuron conspicuously pubescent ventrally. Metepisternum glabrous, reticulate in dorsal part and pubescent ventrally. Lateral propodeal carina percurrent, raised into conspicuous ridge through entire length; median propodeal area glabrate.

Petiole 0.68 times as long as wide in lateral view. Tergum 8 not exposed; relative length of T3 through T7: 1.9:1.0:1.5:3.9:1.6; T3 glabrous; T4 and T5 glabrous, finely punctate; T6 and T7 finely, densely punctate, each with single row of pubescence dorso-laterally in the middle. Apical teeth of metatibia long, slender, and pointed apically. Length of 1 st metatarsomere 0.66 times combined length of 2–5mt.

MALE. Length 6.5–8.0 mm. Antenna 14-segmented.

Distribution. China: Hainan, Guangxi, Fujian, Jiangxi (Oriental regions). It seems likely that new species may also be found in the provinces of Guangdong, Hunan and Taiwan.
