description: Emphytopsis zhongi Wei & Niu, sp. nov. (Fig. 5)
Description: Holotype: Ƥ.
Body length 11 mm. Yellow brown; ocellar spot, subtriangular spot on posterior half of postocellar area, a curved and obscure stripe on temple (Fig. 5b), apex of mandible, lateral stripe on pronotum, outer side of propleuron largely, broad elliptical spot on prescutum, one large elongated spot connected to one small round spot on each lobe of scutum, centre of mesopostnotum, small spot near cenchrus, a pair of small spots on posterior part of metapostnotum, ventral side of mesepisternum, a stripe on posterior margin of mesepimeron (Fig. 5c), a pair of broad maculae on posterior 0.6 of abdominal tergites 1, 3–8, two short and narrow stripes near posterior margin of tergite 2, and apical sheath black; distance between two black maculae on tergites 1–5 distinctly more than 2× diameter of middle ocellus; ventral part of tergite 7 partly black (Fig. 5c). Legs pale yellow, apical 0.33 of hind femur, apical 0.25 of hind tibia black. Antenna brown, darkened toward apex, outer side of scape yellow brown. Body hairs silver. Wings hyaline, vein C, basal 0.33 of stigma pale brown, apical 0.67 of stigma and other veins blackish brown (Figs. 5a, 5c).
Clypeus sparsely and minutely punctured, frons, postocellar area and inner orbits with distinct, minute punctures, head otherwise polished, shiny; mesonotum scarcely and minutely punctured, mesoscutellum, posttergite and mesepisternum evenly punctured, interspaces broad, strongly shiny; metanotum impunctate, strongly shiny; metapleuron distinctly microsculptured; all abdominal tergites with fine microsculptures and sparse, shallow punctures.
Anterior margin of labrum roundly protruding, anterior margin of clypeus deeply incised to 0.65× clypeus length; malar space 0.6× diameter of middle ocellus; POL: OOL: OCL=14: 21: 33; postocellar area weakly elevated, as long as wide, lateral furrows roundly curved outwards at middle; head behind eyes in dorsal view hardly shorter than eye (12: 13), lateral sides straight, parallel (Fig. 5b). Antenna not very slen- der, relative length of antennomeres about 7: 4: 17: 14: 12: 7: 6: 6: 7. Mesoscutellum roundly elevated, posterior slope shorter than anterior slope; mesepisternum indistinctly elevated; distance between cenchri 1.5× longest axis of a cenchrus. Hind basitarsus as long as tarsomeres 2–5 together; claw with inner tooth slightly shorter than outer tooth. Vein R+M in forewing as long as free sector of Sc, lower outer corner of cell 2Rs slightly extended, vein 2r joining cell 2Rs slightly beyond middle. Petiole of anal cell in hind wing about 0.4× length of vein cu-a. Ovipositor sheath 1.4× length of metabasitarsus, apical sheath as long as basal plate, subtriangular at apex in lateral view (Fig. 5d); in dorsal view sheath about 2× as wide as cercus, setae on lateral sides of sheath short, hardly curved. Lancet with 23 serrulae, membrane between 8th and 9th serrulae distinctly wider than width of a serrula, 5th–7th serrulae as in Fig. 5e, each with 4 large subbasal teeth, not at same level; 11th–12th serrulae as in Fig. 5f.
Male: Unknown.
Etymology: This species is named after the collector of the type specimen.
Specimen examined: Holotype, Ƥ, South slope of Mt. Lushan (115º57.373´E, 29º34.639´N), Jiangxi Province, alt. 818 m, 17 May, 2007, Yihai Zhong (CSCS).
Distribution: China (Jiangxi).
Remarks: This new species is similar to E. nigricornis Wei & Xu sp. nov. and E. quadrata Wei & Xu, sp. nov. See the above key for the differences between the three species. E. zhongi is also similar to E. punctata Wei & Nie, 1998, but differs from the latter in postocellar area as long as wide, lateral sides of head behind eyes straight, parallel; apical 0.33 of hind femur and apex of hind tibia black, ventral side of hind femur without black stripe, distance between two black maculae on tergites 1–5 distinctly more than 2× diameter of middle ocellus; mesepisternum evenly punctured with broad interspaces and ovipositor sheath distinctly longer than metabasitarsus.
