Type material.

Holotype, ♂ (ZUH), "S. China: Hunan, nr Chengbu, Nan Mt., Shaoyang, 1500 m, 10-11.VI.2009, Xi-Ying Li, RMNH’09”.

Diagnosis.

Mandible with a short ventral carina (Fig. 20); clypeus dark brown; hind tibia completely pale yellowish or brownish-yellow basally; medio-posterior depression of mesoscutum absent (Fig. 15); mesosoma slender (Fig. 13); propodeum without a transverse carina subbasally (Fig. 16); vein m-cu of fore wing slightly postfurcal (Fig. 14).

Description.

Holotype, ♂, length of body 1.6 mm, of fore wing 2.2 mm.

Head. Antenna with 26 segments and 1.3 times as long as fore wing (Fig. 13); length of third segment 1.5 times fourth segment and without thyloids and shiny, length of third, fourth and penultimate segments 5.3, 3.5, and 2.5 times their width, respectively (Fig. 21); length of maxillary palp 1.2 times height of head; labial palp segments rather short; occipital carina dorsally absent; median groove behind stemmaticum absent; hypostomal carina narrow (Fig. 20); length of eye in dorsal view twice temple; frons flat and glabrous medially, smooth and laterally distinctly convex and glabrous; face smooth, medially slightly elevated (Fig. 18); width of clypeus 1.8 times its maximum height and 0.55 times width of face, clypeus convex, smooth and its ventral margin differentiated and slightly concave (Fig. 18); hypoclypeal depression medium-sized (Fig. 18); malar suture indicated as slightly impressed narrow groove; mandible triangular, moderately convex and with fine ventral carina (Fig. 20).

Mesosoma. Length of mesosoma 1.4 times its height; dorsal pronope absent (Fig. 19); pronotal side smooth, but posteriorly slightly superficially crenulate; epicnemial area smooth dorsally; precoxal sulcus only medially distinctly impressed, narrow and smooth (Fig. 13); rest of mesopleuron smooth; pleural sulcus smooth, but ventrally slightly crenulate; mesosternal sulcus narrow and finely crenulate; notauli absent on disc, except for a short crenulate part anteriorly (Fig. 15); mesoscutum glabrous; medio-posterior depression of mesoscutum absent (Fig. 15); scutellar sulcus narrow and finely crenulate; scutellum smooth and slightly convex; dorsal surface of propodeum largely smooth without medio-longitudinal carina and posteriorly mainly finely rugulose (Fig. 16).

Wings. Fore wing (Fig. 14): pterostigma sublinear; 1-R1 reaching wing apex and 1.3 times as long as pterostigma; r:3-SR:SR1 = 3:21:43; 2-SR:3-SR:r-m = 10:21:6; r slightly widened; 1-M straight; SR1 weakly sinuate; m-cu slightly postfurcal; cu-a slightly postfurcal and 1-CU1 slender; first subdiscal cell narrowly open, CU1b absent; apical quarter of M+CU1 sclerotized. Hind wing (Fig. 14): M+CU:1-M:1r-m = 10:9:5; cu-a straight, short; m-cu absent; 1-1A curved.

Legs. Length of femur, tibia and basitarsus of hind leg 4.6, 9.5 and 7.2 times as long as wide, respectively; setae of hind femur and tibia moderately long (Fig. 17).

Metasoma. Length of first tergite 1.3 times its apical width, its surface evenly convex medially and with longitudinal (partly superficial) fine rugae and dorsal cari nae remain separated and up to middle of tergite (Fig. 16); basal quarter of second tergite with oblique striae medially (Fig. 16); second suture obsolescent; third and following tergites smooth.

Colour. Dark brown; palpi and tegulum pale yellowish; scapus, pedicellus and base of third segment, legs (but hind femur and tibia slightly darkened apically), metasoma baso-ventrally and apex of third-seventh tergites brownish-yellow; mesopleuron below precoxal sulcus chestnut-brown; pterostigma and veins mainly pale brown; wing membrane subhyaline.

Molecular data. None.

Distribution.

*China (Hunan).

Biology.

Unknown.

Etymology.

Name derived from “brunneus” (Latin for brown) and “clypeus”, because of the brown clypeus.

Notes.

Runs in the key by Chen and Weng (2005) to Phaedrotoma larga (Weng & Chen, 2005) comb. n. It differs by having the occipital carina curved ventrally, the clypeus 1.8 times wider than high (2.6 times in Phaedrotoma larga ) and the first tergite 1.3 times as long as wide apically (0.9 times).
