Type material.

Holotype, ♀ (ZUH), "S. China: Hunan, nr Zhangjiajie, Badagong Mts, Tian Ping Mt., 9-13.VII.2009, 550 m, Xi-Ying Li, RMNH’10”, "CVA4244, sp. 10".

Diagnosis.

Mandible without ventral carina; ventral rim of clypeus narrow and upcurved (Fig. 68); clypeus medium-sized; face rather tuberculate medio-ventrally (Fig. 68); pronotum without distinct pronope (Fig. 70); propleuron smooth subposteriorly; pronotum short; notauli nearly complete and finely crenulate (Fig. 65); precoxal sulcus present anteriorly and medially, wide and crenulate (Fig. 63); postpectal carina completely absent; propodeum with a transverse carina subbasally (Fig. 65); first discal cell of fore wing less transverse than in Coleopioides postpectalis (Fig. 64); vein m-cu of fore wing twice longer than vein 2-SR+M; second tergite smooth (Fig. 66).

Description.

Holotype, ♀, length of body 1.6 mm, of fore wing 2.0 mm.

Head. Antenna with 19 segments and 0.8 times as long as fore wing; length of third segment 1.2 times fourth segment, length of third, fourth and penultimate segments 3.0, 2.5, and 2.2 times their width, respectively (Fig. 71); length of maxillary palp 0.9 times height of head; labial palp segments short; occipital carina rather close to hypostomal carina and dorsally and behind upper half of eye absent (Fig. 69); no depression behind stemmaticum; hypostomal carina medium-sized; length of eye in dorsal view 2.6 times temple; frons medially convex, depressed behind antennal sockets and laterally convex, entirely glabrous; face smooth, evenly convex; width of cly-peus twice its maximum height and 0.55 times width of face, clypeus convex, smooth and its ventral margin differentiated, narrow, thin, straight and upcurved (Fig. 68); hypoclypeal depression rather large (Fig. 69); malar suture present; mandible normal, slightly convex and without ventral carina (Fig. 69).

Mesosoma. Length of mesosoma 1.3 times its height; dorsal pronope absent (Fig. 70); pronotal side smooth, but distinctly crenulate posteriorly and a few crenulae anteriorly, no ventral oblique carina (Fig. 63); epicnemial area largely smooth dorsally, with few weak crenulae; precoxal sulcus anteriorly and medially present, wide, coarsely rugose-crenulate (Fig. 63); rest of mesopleuron smooth; pleural sulcus smooth, except for some indistinct crenulae ventrally; mesosternal sulcus rather wide and with few crenulae, without postpectal carina; notauli nearly complete, narrow and finely crenulate (Fig. 65); mesoscutum smooth and with some setae medially; medio-posterior depression of mesoscutum round and small (Fig. 65); lateral margin of mesoscutum crenulate; scutellar sulcus widely and coarsely crenulate (Fig. 65); scutellum smooth and slightly convex; dorsal surface of propodeum short and with short medio-longitudinal carina, transverse carina strong, posterior surface largely smooth, with median and sublateral carinae (Fig. 65).

Wings. Fore wing (Fig. 64): pterostigma wide elliptical; 1-R1 reaching wing apex and 1.5 times as long as pterostigma; r:3-SR:SR1 = 2:23:37; 2-SR:3-SR:r-m = 15:23:7; r short and slender; 1-M nearly straight; SR1 slightly curved; m-cu postfurcal by half its length; cu-a postfurcal and 1-CU1 widened; first subdiscal cell closed, CU1b short; apical quarter of M+CU1 sclerotized; first discal cell of fore wing comparatively short. Hind wing (Fig. 64): M+CU:1-M:1r-m = 18:12:7; cu-a slightly reclivous; m-cu absent; 1-1A curved.

Legs. Length of femur, tibia and basitarsus of hind leg 4.8, 7.8 and 3.7 times as long as wide, respectively; hind femur and tibia with moderately long setae (Fig. 67).

Metasoma. Length of first tergite equal to its apical width, its surface strongly convex gradually medially, coarsely rugose and with dorsal carinae united near apical fifth of tergite (Fig. 66); second suture absent; second and following tergites smooth; second and third tergites 0.6 times as long as metasoma after first tergite; length of setose part of ovipositor sheath 0.05 times fore wing and 0.2 times hind tibia (Figs 63, 72).

Colour. Dark brown; mandible, palpi, scapus, tegulae and legs (but telotarsi darkened) pale yellowish; clypeus, malar space and mesopleuron largely yellowish-brown; pterostigma and veins brown; wing membrane slightly infuscate below base of pterostigma, remainder subhyaline.

Molecular data. COI, 16S, 28S (CVA 4244).

Distribution.

*China (Hunan).

Biology.

Unknown.

Etymology.

Name derived from “diversus” (Latin for “different”) and “notum”, because of the differently sculptured mesoscutum.

Notes.

The new species runs in the key by Chen and Weng (2005) to Xynobius indagatrix (Weng & Chen, 2005) comb. n.; Coleopioides diversinotum differs by lacking a dorsope (present in Xynobius indagatrix ), the length of the eye in dorsal view 2.6 times temple (4.2 times in Xynobius indagatrix ), length of the first tergite about equal to its apical width (1.3 times) and the propodeum with strong transverse carina and carinate (densely rugose and without distinct transverse carina).
