Type material. HOLOTYPE female: CHINA, Hainan, Jianfengling, Tianchi , 2008 . V.7 (Jing- Xian Liu) (The type specimen is deposited in the Insect Collection of Zhejiang A & F University).

Etymology. The species epithet of the new species is derived from Latin, nigrum, dark, and caput, head, referring to the dark head of the species.

Diagnosis. Paramblynotus nigricaputus is very similar to P. distinctus , P. fraxini , and P. kosugii . The new species can be easily separated from the other three species by having the occiput vertically carinate and the first metatarsomere without apical prolonged protuberance. It further differs from P. distinctus in having the body entirely black (head yellow in the latter); the flagellum not distinctly enlarged distally; 3the gena foveate-punctate reticulate;and the scutellar trough divided a median and two submedian carinae. It further differs from P. fraxini in having 1) lateral propodeal carinae slightly raised; 2) scutellar trough divided by a median and two submedian carinae, and 3) larger in size. It further differs from P. kosugii in having 1) scutellar trough divided a median and two submedian carinae; 2) mesoscutellum posteriorly without an inflection prior to posterior projection, and 3) posterior margin of mesoscutellum rounded, not truncate. In addition, it differs from both P. fraxini , and P. kosugii in having 1) metasoma black and 2) coxa and femur black, and tibia and tarsus for all legs light yellow.

Description. FEMALE (holotype). Body length 5.3 mm. Antennae with 13-segments and filiform. Rs+M of fore wing ( Fig. 37 ) arising from anterior third of basal vein; marginal cell 3.2 times as long as wide and about as long as submarginal cell.

Coloration. Head, antenna, mesosoma black; metasoma dark brown; all legs with black coxa and femur, light yellow tibia and tarsus. Wings transparent and tinted light brown, with a ferruginous macula covering marginal cell, except centrally, and area of submarginal cell along vein 2r.

Head ( Figs. 33–34 ). Vertex foveate-reticulate, medially longitudinally carinate, and with longitudinal carinate components laterally. Eye extended laterally beyond outer margin of gena. Ocellar plate distinctly raised, foveatereticulate, defined laterally by carina lined along interior side with a row of large foveae. Median frontal carina simple and present only between antennal sockets. Dorsal frons foveate laterally; antennal scrobe distinctly depressed and irregularly punctate-foveate with longitudinal rugosity dorsally. Gena foveate-punctate; ventral frons and clypeus foveate-punctate; anterior tentorial pits distinct. Lateral occipital carina not reaching vertex. Occiput glabrous, with vertical carinae.

Mesosoma ( Figs. 35–36 ). Anterior flange of pronotum glabrous, with fine transverse striation; submedian pronotal depressions separated medially. Anterior plate of pronotum densely punctate medially and glabrous laterally. Pronotum dorsomedially raised, but distinctly lower than mesoscutum; pronotal crest raised medially into a small peak. Lateral pronotal carina distinct, reaching pronotal crest dorsomedially. Lateral surface of pronotum foveolate-reticulate. Dorsal pronotal area glabrate, present only along anterior third of posterior margin of pronotum. Mesoscutum slightly arched dorsally, transversely costate with superficial foveae set in rows. Scutellar sulcus divided by a median and two submedian carinae; mesoscutellum posteriorly without an inflection prior to posterior projection; posterior margin of mesoscutellum rounded, rather than truncate. Mesopleural triangle conspicuously pubescent, well defined ventrally by smoothly curved carina. Median mesopleural impression percurrent, glabrous, with transverse costae. Upper mesopleuron glabrous with punctures anteriorly. Lower mesopleuron glabrous and sparsely punctate and foveate; pubescent in ventral impression. Metepisternum foveolate-reticulate in dorsal part, with small elevated glabrous area medially, conspicuously pubescent ventrally. Lateral propodeal carina not raised, conspicuously pubescent dorsally; median propodeal area glabrate; median longitudinal carina present anteriorly and submedian transverse carina prominent.

Petiole 0.8 times as long as wide in lateral view. Tergum 8 not exposed; relative length of T3–7: 1.8:1.0:1.4:2.3:1.5; T3 and T4 glabrous; T5 finely densely punctate; T6 densely punctate, with a middle row of pubescence; T7 densely punctate, with a broad band of conspicuous pubescence in anterior dorsal. Apical teeth of metatibia long, slender, pointed apically, the first of the metatarsomere lacking an apical prolonged protuberance. Length of 1 st metatarsomere 0.66 times combined length of 2–5mt.

MALE. Unknown.

Distribution. China: Hainan (Oriental region).
