Type material.

Holotype, ♀, C China, Hubei Province, Shennongjia, Honghua, 21.viii.2000, Qing-E Ji, average altitude 1800m. Paratype: 1♀, same label data as holotype.

Description.

Holotype, ♀, length of antenna 2.2 mm, of fore wing longer than 3.1 mm, and of body 3.3 mm.

Head. Antenna with 15 antennomeres and 0.7 × as long as body (Fig. 17A View Figure 17 ); scapus rather stout and straight, weakly expanded, 4.4 × longer than its maximum width, with distinct carina ventrally which is curved from middle, sparsely setose (Fig. 17B View Figure 17 ); antenna geniculated at first flagellomere and first flagellomere modified: first flagellomere slender and subcylindrical with long hook apically, second flagellomere inserted on first flagellomere near its middle (Fig. 17B View Figure 17 ); first flagellomere 3.0 × longer than second flagellomere, first, second and penultimate flagellomere 7.4, 2.1 and 1.9 × longer than wide, respectively (Fig. 17B View Figure 17 ); eye 1.8 × longer than temple in dorsal view, inner side of eye curved (Fig. 17C View Figure 17 ); temples roundly narrowed behind eyes; ocelli small, OOL:OD:POL = 22:4:9 (Fig. 17C View Figure 17 ); frons and vertex smooth to punctate (Fig. 17C View Figure 17 ); occipital carina nearly complete, very narrowly interrupted and straight dorsally (Fig. 17C View Figure 17 ); face 1.7 × wider than high, smooth and densely setose (Fig. 17D View Figure 17 ); clypeus smooth, narrow than face, slightly convex, 3.5 × wider than high (Fig. 17D View Figure 17 ); dorsal margin of clypeus far below level of ventral margin of eye in anterior view (Fig. 17D View Figure 17 ); tentorial pits large (Fig. 17D View Figure 17 ); malar suture wide, length of malar space 1.8 × basal width of mandible (Fig. 17D View Figure 17 ).

Mesosoma. Length of mesosoma 1.4 × its height (Fig. 18F View Figure 18 ); side of pronotum crenulated anteriorly, largely smooth and shiny (Fig. 18F View Figure 18 ); propleuron smooth (Fig. 18F View Figure 18 ); mesopleuron smooth and shiny (Fig. 18F View Figure 18 ); prepectal medio-ventral carina present (Fig. 18F View Figure 18 ); episternal scrobe short (Fig. 18F View Figure 18 ); precoxal sulcus long, narrow and crenulate (Fig. 18F View Figure 18 ); mesonotum sparsely setose, convex, smooth and slightly shiny (Fig. 18E View Figure 18 ); notauli narrow and crenulated to rugose; mesoscutum sparsely setose, flat (Fig. 18E View Figure 18 ); scutellar sulcus smooth with one distinct crenula (Fig. 18E View Figure 18 ); scutellum convex, smooth (Fig. 18E View Figure 18 ); metapleuron largely reticulate (Fig. 18F View Figure 18 ); propodeum reticulate laterally rugose (Fig. 18G View Figure 18 ).

Wings. Fore wing (Fig. 18I View Figure 18 ): vein 1-SR+M absent; vein 1-R1 0.8 × as long as pterostigma; vein SR1+3-SR curved; r:2-SR = 5:27; vein r issued from middle of pterostigma; vein m-cu cross vein 2-SR; vein cu-a longer than vein 1-CU1, postfurcal.

Legs. Fore leg: tibia 2.7 × longer than coxa, 0.9 × as long as femur, and femur flat, 3.0 × longer than wide; middle leg: tibia 6.2 × longer than coxa, 1.3 × longer than femur; hind leg: tibia 4.0 × longer than coxa, 1.4 × longer than femur; hind coxa smooth, 1.2 × longer than wide; hind femur, tibia and basitarsus 6.4, 13.3 and 8.8 × longer than wide, respectively; hind basitarsus 0.3 × as long as tibia, and 0.5 × as long as combined second to fifth tarsal segments; hind fourth tarsal segment 0.8 × as long as fifth tarsal segment.

Metasoma. First tergite 1.9 × longer than its apical width, apical width 2.6 × its minimum width, with dorsope at basal 0.3 (Fig. 18H View Figure 18 ); first tergite basally rugulose, laterally striate to rugulose (Fig. 18H View Figure 18 ); following tergites smooth and shiny; ovipositor sheath and ovipositor typical, ovipositor curved to pointing upward apically (Fig. 17A View Figure 17 ).

Colour. Yellowish brown to dark brown; palpi, basal antenna and legs yellowish brown; antenna and head largely brown; wing membrane hyaline, pterostigma and veins brown.

Remarks.

This new species is similar to S. (S.) latiscapus Belokobylskij, 2000, but differs from it as follows: (i) antenna with 15 antennomeres, first flagellomere 5.8 × longer than second flagellomere (antenna with 17-18 antennomeres, first flagellomere 2.8-3.0 × longer than second flagellomere in S. latiscapus ); (ii) eye 1.8 × longer than temple in dorsal view, inner side of eye curved (eye 1.6 × longer than temple in dorsal view and inner side of eye straight).

Biology.

Unknown.

Distribution.

Palaearctic: China (Hubei).

Etymology.

Named after the narrowly interrupted occipital carina; “interruptus” is Latin for "broken apart".
