description: <i>Tersilochus (Tersilochus) ningxiator</i> Khalaim &amp; Sheng, sp. n. urn:lsid:zoobank.org:act: 186EA92B-0E56-4746-B7F4-8418E75013F0 Figs 7, 8, 21-26 <b>Diagnosis.</b> The new species belongs to the “cognatus” species group (correct name for the “jocator” species group according to Horstmann 2005) as the ovipositor has two dorsal teeth (Figs 8, 26), and resembles the European <i>T. petiolaris</i> Horstmann in the smooth first tergite, slightly elongate thyridia (Fig. 25), antenna with 20 flagellomeres (Fig. 22), and ovipositor sheath 1.8 times as long as the first tergite (Fig. 21). <i>T. ningxiator</i> sp. n. may be distinguished from this species by the well-developed sternaulus (Fig. 23), the mesopleuron smooth and distinctly punctate above sternaulus (Fig. 23), and the metasoma darker (Fig. 21). <b>Description.</b> Female. Body length 3.9 mm. Head roundly narrowed behind eyes in dorsal view (Fig. 7), temple 0.86 times as long as eye width (Fig. 7). Flagellum of antenna with 20 segments; middle flagellomeres 1.4, subapical flagellomeres 1.2 times as long as wide (Fig. 22). Upper tooth of mandible longer than lower tooth. Malar space 0.8 times as long as basal width of mandible. Clypeus broad, coriaceous and indistinctly punctate in its upper 3/4, and smooth in its lower 1/4. Face and frons densely granulate and more or less distinctly punctate. Vertex with shallow granulation and indistinct punctures. Temple finely granulate to almost smooth, partly finely punctate. Mesoscutum densely granulate and finely and densely punctate. Sternaulus well-developed, rather long, upcurved anteriorly, with transverse wrinkles below (Fig. 23). Mesopleuron above sternaulus finely but distinctly and moderately densely punctate, mostly smooth between punctures (Fig. 23). Mesosternum smooth and densely punctate. Propodeum with spiracle adjacent to pleural carina; dorsolateral area finely punctate, smooth anteriorly and granulate posteriorly; apical area uneven. Basal area narrow, weakly widened anteriorly, more than twice as long as wide, and about half as long as apical area (Fig. 24). Fore wing length 3.6 mm. First section of radial vein longer than width of pterostigma. Metacarp somewhat short of apex of fore wing. Second recurrent vein postfurcal, unpigmented in anterior part. Nervellus of hind wing weakly reclivous. Tarsal claws not pectinate. First tergite length 0.96, posterior width 0.33 mm; tergite entirely smooth, moderately slender. Glymma in anterior 0.55 of first tergite, medium-sized, joined by a distinct furrow to ventral part of postpetiole. Th yridia distinct, slightly elongate (Fig. 25). Second tergite length 0.33 mm. Ovipositor upcurved, with two dorsal subapical teeth, finely denticulate ventrally (Figs 8, 26); sheath 1.75 mm long, about 1.8 times as long as first tergite (Fig. 21). <b>Coloration.</b> Body black. Mandible (excepting teeth) brownish yellow. Clypeus with narrow brownish band along its lower margin. Tegula yellow-brown. Pterostigma brown. Metasoma behind first segment yellow-brown ventrally to black dorsally. Fore and mid legs with coxae for the greater part darkened, yellowish ventrally, femora yellow-brown, and tibia yellow-brown ventrally and infuscate dorsally. Hind leg with coxa entirely black, femur brown on inner surface and dark brown on outer surface, tibia brownish fuscous, basitarsus brownish basally to infuscate apically. All tarsi infuscate, but some tarsomeres narrowly brownish basally and apically. Male unknown. <b>Type material.</b> Holotype female, China, Ningxia Hui Autonomous Region, Liupanshan, 35°24’ N, 106°23’ E, 1820 m, 11.VIII.2005, coll. M.-L. Sheng (GSFPM). <b>Etymology.</b> From the type locality.
