Type material.
Holotype, ♀, SE China, Fujian Province, Mt Wuyi, Guadang, 13.viii.1988, Jian-hua Ge, average altitude 1800 m. Paratype: 1♀, SE China, Fujian Province, Mt Wuyi, Xianfengling, 8.viii.1988, Jian-wen Chen, average altitude 1400 m.
Description.
Holotype, ♀, length of antenna 2.8 mm, of fore wing 2.1 mm, and of body 3.1 mm (Fig. 2A View Figure 2 ).
Head. Antenna with 18 antennomeres and 1.3 × longer than fore wing, 0.9 × as long as body (Fig. 2A View Figure 2 ); scapus rather long and slender and expanded, 9.3 × longer than its maximum width, evenly curved, with a very small tooth-shaped horn, finely setose (Fig. 2C View Figure 2 ); first to fifth flagellomeres modified: flagellomeres geniculated at fifth flagellomere, first to fourth flagellomeres fused, first to fifth flagellomeres with carina ventrally, fourth and fifth flagellomeres with hook and, hook of fourth flagellomere larger than hook of fifth (Fig. 2D View Figure 2 ); first flagellomere 2.0 × longer than second flagellomere, first, second and penultimate flagellomere 3.2, 1.5 and 1.8 × longer than wide, respectively (Fig. 2D View Figure 2 ); eye 1.7 × longer than temple in dorsal view (Fig. 2E View Figure 2 ); temples roundly behind eyes (Fig. 2E View Figure 2 ); ocelli medium-sized, OOL:OD:POL = 71:24:41 (Fig. 2E View Figure 2 ); frons and vertex largely smooth (Fig. 2E View Figure 2 ); occipital carina nearly complete, interrupted medio-dorsally (Fig. 2E View Figure 2 ); face 1.4 × wider than high, smooth (Fig. 2F View Figure 2 ); clypeus smooth, narrow than face, convex, 2.0 × wider than high (Fig. 2F View Figure 2 ); dorsal margin of clypeus under level of ventral margin of eye anterior (Fig. 2F View Figure 2 ); tentorial pits large (Fig. 2F View Figure 2 ); malar suture shallow and narrow, length of malar space 1.2 × basal width of mandible (Fig. 2F View Figure 2 ); mandibles long and stout.
Mesosoma. Length of mesosoma 2.4 × its height (Fig. 3H View Figure 3 ); side of pronotum crenulated anteriorly, largely smooth (Fig. 3H View Figure 3 ); propleuron smooth and shiny (Fig. 3H View Figure 3 ); mesopleuron smooth (Fig. 3H View Figure 3 ); prepectal medio-ventral carina present (Fig. 3H View Figure 3 ); episternal scrobe short and wide (Fig. 3H View Figure 3 ); precoxal sulcus long, wide and crenulate (Fig. 3H View Figure 3 ); mesonotum moderately sparsely setose, flat, smooth and shiny (Fig. 3G View Figure 3 ); notauli narrow and carina; mesoscutum sparsely setose, flattened (Fig. 3G View Figure 3 ); scutellar sulcus wide and rugose with one distinct crenula (Fig. 3G View Figure 3 ); scutellum flat, smooth (Fig. 3G View Figure 3 ); metapleuron reticulate (Fig. 3H View Figure 3 ); propodeum with short basal carina but not median area, largely rugulose (Fig. 3I View Figure 3 ).
Wings. Fore wing (Fig. 3K View Figure 3 ): vein 1-SR+M absent; vein 1-R1 0.7 × as long as pterostigma; vein SR1+3-SR curved; r:2-SR = 17:58; vein r issued behind middle of pterostigma; vein m-cu cross vein 2-SR; vein cu-a slightly short than vein 1-CU1 and postfurcal.
Legs. Fore leg modified: tibia strong curved, 1.2 × longer than coxa, 0.8 × as long as femur, and femur 3.1 × longer than wide; middle leg: tibia 5.2 × longer than coxa, 1.2 × longer than femur; hind leg: tibia 3.5 × longer than coxa, 1.4 × longer than femur; hind coxa smooth, 1.2 × longer than wide; femur, tibia and basitarsus 7.7, 15.6 and 6.0 × longer than wide, respectively; hind basitarsus 0.3 × as long as hind tibia, and 0.6 × as long as combined second to fifth tarsal segments; hind fourth tarsal segment 0.8 × as long as fifth tarsal segment.
Metasoma. First tergite quiet slender, 2.6 × longer than its apical width, apical width 1.9 × its minimum width, with large dorsope basally (Fig. 3J View Figure 3 ); first tergite smooth basally, striate laterally (Fig. 3J View Figure 3 ); following tergites smooth and shiny; ovipositor sheath short and robust, 0.1 × as long as fore wing; ovipositor short and robust (Fig. 2B View Figure 2 ).
Colour. Yellowish brown to brown; palpi pale yellow; legs yellowish brown; face, antenna, ovipositor sheaths and ovipositor yellowish brown; wing membrane hyaline, pterostigma and veins brown; mesosoma and first metasomal tergite brown.
Remarks.
This new species is similar to S. (E.) thayi Belokobylskij, 2000 from Vietnam, but differs from it as follows: (i) 18 antennomeres, scapus 9.3 × longer than its maximum width, first to fifth flagellomeres with carina ventrally, fourth and fifth flagellomeres with hook and hook of fourth flagellomere larger than hook of fifth flagellomere (19 antennomeres, scapus 7.5 × longer than its maximum width, first to fifth flagellomeres with carina ventrally, only fifth flagellomeres with hook in S. thayi ); (ii) first metasomal tergite smooth basally, striate laterally (first tergite entirely and densely striate); (iii) ovipositor sheath shorter, 0.1 × as long as fore wing (ovipositor sheath longer, 0.2 × as long as fore wing); (iv) body reddish brown (body yellowish brown).
Biology.
Unknown.
Distribution.
Oriental: China (Fujian).
Etymology.
Named after the ventral carina of the first to fifth flagellomeres: carina means keel in Latin and fero is Latin for to carry.
