Type material.
Holotype, ♀, SW China, Yunan Province, Wenshan City, Malipo County, Zhongzaichapai, 22.vi. 2017, Yan-Qiong Peng, 1972m.
Description.
Holotype, ♀, length of antenna 1.8mm, of fore wing 2.0 mm, and of body 2.2 mm.
Head. Antenna with 15 antennomeres and 0.9 × as long as fore wing, 0.8 × as long as body (Fig. 21A View Figure 21 ); scapus long and slender, weakly expanded, 5.2 × longer than its maximum width, evenly curved, without horn, finely setose (Fig. 21C View Figure 21 ); first and second flagellomeres densely setose and modified: first flagellomere slender and long, second flagellomere stout and weakly expanded (Fig. 21D View Figure 21 ); first flagellomere 2.6 × longer than second flagellomere, first, second and penultimate flagellomere 5.1, 1.9 and 1.9 × longer than wide, respectively (Fig. 21C View Figure 21 ); eye 1.8 × longer than temple in dorsal view; temples roundly narrowed behind eyes (Fig. 22E View Figure 22 ); ocelli medium-sized, OOL:OD:POL = 41:14:23 (Fig. 22E View Figure 22 ); frons and vertex largely smooth (Fig. 22E View Figure 22 ); occipital carina nearly complete, narrowly interrupted medio-dorsally (Fig. 22E View Figure 22 ); face nearly 1.5 × wider than high, smooth and shiny (Fig. 22F View Figure 22 ); clypeus smooth and shiny, wider than face, strongly convex, 3.0 × wider than high (Fig. 22F View Figure 22 ); dorsal margin of clypeus above level of ventral margin of eye anterior (Fig. 22F View Figure 22 ); tentorial pits large (Fig. 22F View Figure 22 ); malar suture short, length of malar space 0.5 × basal width of mandible (Fig. 22F View Figure 22 ); mandibles long, nearly completely overlapping when closed (Fig. 22F View Figure 22 ).
Mesosoma. Length of mesosoma 2.3 × its height (Fig. 22H View Figure 22 ); side of pronotum crenulated anteriorly and medially, largely smooth (Fig. 22H View Figure 22 ); propleuron smooth (Fig. 22H View Figure 22 ); mesopleuron smooth (Fig. 22H View Figure 22 ); prepectal medio-ventral carina present (Fig. 22H View Figure 22 ); episternal scrobe short and wide (Fig. 22H View Figure 22 ); precoxal sulcus wide and crenulate (Fig. 22H View Figure 22 ); mesonotum moderately sparsely setose, flat, smooth (Fig. 22G View Figure 22 ); notauli narrow, smooth, mesoscutum sparsely setose, flattened (Fig. 22G View Figure 22 ); scutellar sulcus very wide and smooth with one distinct crenula (Fig. 22G View Figure 22 ); scutellum flat, smooth (Fig. 22G View Figure 22 ); metapleuron reticulate (Fig. 22H View Figure 22 ); propodeum with rather long basal carina and pentagon-shaped median area, largely smooth (Fig. 22I View Figure 22 ).
Wings. Fore wing (Fig. 22J View Figure 22 ): vein 1-SR+M absent; vein 1-R1 0.4 × as long as pterostigma; vein SR1+3-SR strongly curved; r:2-SR = 11:46; vein r issued behind middle of pterostigma; vein m-cu cross vein 2-SR; vein cu-a longer than vein 1-CU1 and postfurcal; basal and subbasal cells of fore wing similarly setose as other cells.
Legs. Fore leg: tibia 5.2 × longer than coxa, 1.1 × longer than femur; middle leg: tibia 3.9 × longer than coxa, 1.1 × longer than femur; hind leg: tibia 3.7 × longer than coxa, 1.6 × longer than femur; hind coxa smooth, 1.2 × longer than wide; femur, tibia and basitarsus 5.6, 14.5 and 7.7 × 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; fourth hind tarsal segment 0.9 × fifth tarsal segment.
Metasoma. First tergite slightly narrowed behind spiracle, 2.2 × longer than its maximum width, apical width 2.9 × its minimum width, without dorsope and laterope (Fig. 22I View Figure 22 ); first tergite rugose basally, striate laterally and subapically (Fig. 22I View Figure 22 ); following tergites smooth and shiny; ovipositor sheath 0.1 × as long as fore wing; ovipositor strongly curved upwards (Fig. 21B View Figure 21 ).
Colour. Yellowish brown to dark brown; face, basal part of antenna, palpi and legs yellowish brown; scutellum, metanotum, brown; wing membrane hyaline, pterostigma and veins dark brown; second to thirteenth flagellomeres, propodeum and metasomal segments dark brown.
Remarks.
This new species can be distinguished from related species by the combination of 15 antennomeres, scapus without horn, first and second flagellomere densely setose and modified, occipital carina narrowly interrupted medio-dorsally, very wide scutellar sulcus and ovipositor short and strongly curved upwards.
