Type material.

Holotype, ♀ (ZUH), "S. China: Hunan, Shaoyang, Chengbu, Nan Mts., 1.VI.1985, Bai-Hua Xia, No. 300".

Diagnosis.

Head strongly transverse and yellow; clypeus very wide (Fig. 300); mandible large, gradually widened baso-ventrally and resulting in comparatively robust teeth (Fig. 301); occipital carina slightly curved ventrally and remaining removed from hypostomal carina; pronotal side striate; notauli nearly complete, basal half crenulate and gradually reduced posteriorly (Fig. 297); scutellar sulcus wide and coarsely crenulate (Fig. 297); surface of propodeum coarsely and densely rugose and without a transverse carina subbasally (Fig. 298); vein 1r-m of hind wing distinctly oblique and 0.3 times vein 1-M (Fig. 296); second tergite smooth.

Description.

Holotype, ♀, length of body 4.2 mm, of fore wing 3.6 mm.

Head. Antenna on unique specimen broken (only 7 segments remaining); third segment 1.1 times as long as fourth segment, length of third and fourth segments 2.0 and 2.0 times their width, respectively (Fig. 295); length of maxillary palp 0.8 times height of head; labial palp segments short; occipital carina far removed from hypo-stomal carina and dorsally absent; hypostomal carina medium-sized; length of eye in dorsal view 0.9 times temple; frons depressed behind antennal sockets and glabrous, smooth (Fig. 302); face smooth, medially broadly elevated (Fig. 300); width of clypeus 3.0 times its maximum height and 0.7 times width of face, clypeus flattened, smooth except for some punctures and its ventral margin thick and distinctly concave (Fig. 301); hypoclypeal depression wide (Fig. 300); malar suture reduced; length of malar space slightly less than basal width of mandible; mandible large, gradually widened baso-ventrally and with a narrow ventral carina (Fig. 301).

Mesosoma. Length of mesosoma 1.3 times its height; dorsal pronope shallow (Fig. 302); pronotal side largely striate (Fig. 303); epicnemial area coarsely crenulate dorsally; precoxal sulcus wide, deep and coarsely crenulate, smooth as rest of mesopleuron (Fig. 303); pleural sulcus smooth; notauli nearly complete, crenulate and gradually reduced posteriorly (Fig. 297); mesoscutum smooth and glabrous; medio-posterior depression of mesoscutum elliptical (Fig. 297); scutellar sulcus wide and coarsely crenulate; scutellum smooth, slightly convex medially; surface of propodeum coarsely and densely rugose (Fig. 298).

Wings. Fore wing (Fig. 296): pterostigma triangular; 1-R1 reaching wing apex and 1.2 times as long as pterostigma; r:3-SR:SR1 = 10:45:93; 2-SR:3-SR:r-m = 37:45:15; 1-M slightly curved, 1-SR+M sinuate and SR1 nearly straight; m-cu and cu-a slightly postfurcal; 1-CU1 hardly widened; first subdiscal cell robust, 3-CU1:CU1b=11:9; apical fifth of M+CU1 unsclerotized. Hind wing (Fig. 296): M+CU:1-M:1r-m = 51:53:17; cu-a straight; m-cu absent; SR present.

Legs. Length of femur, tibia and basitarsus of hind leg 3.0, 6.2 and 4.0 times as long as wide, respectively; hind femur and tibia with medium-sized setae (Fig. 299).

Metasoma. Length of first tergite 0.9 times its apical width, its surface evenly convex medially, coarsely rugose and with dorsal carinae united near apical fifth of tergite (Fig. 298); second and following tergites smooth and normally sclerotized.

Colour. Body black; antenna dark brown; head, tegulae and legs (but hind coxa and hind tarsus brown) yellow; pterostigma and veins brown; wing membrane subhyaline.

Distribution.

*China (Hunan).

Biology.

Unknown.

Etymology.

Etymology. Name derived from “stria” (Latin for "furrow, line") and “notos” (Greek for “back”), because of the longitudinally striate pronotal sides.

Notes.

The new species does not run well in the key by Chen and Weng (2005); it ends near Xynobius indagatrix (Weng & Chen, 2005)comb. n. and Xynobius multiarculatus (Chen & Weng, 2005) comb. n. Both species have dorsope, which is absent in Phaedrotoma striatinota . The pronotal side of both species lacks striae (present in Phaedrotoma striatinota ) and the male of the new species has normally sclerotized tergites (male holotype of Xynobius indagatrix has third-sixth tergites largely membranous).
