Holotype, female, length of body 3.83 mm, of fore wing 3 mm. Head. Antennomeres 16, distinctly shorter than body, average length of 3 rd ���7 th segments 3.2 �� their width, 8 th ���11 th segments 1.6 �� longer than wide; head transverse, width of head 2.2 �� its dorsal length, roundly contracted behind eyes, length of eyes 15.2 �� temple in dorsal view, OOL: OD: POL= 16: 5: 14, longitudinal diameter of eye 2.3 �� height of gena; vertex evenly convex and with transverse rugae behind ocelli, temple finely and longitudinally striate-rugose, frons concave, striate-rugose around antennal sockets (Fig. 2G); length maxillary palp 0.5 �� height of head in anterior view, face striate-rugose, clypeus shiny, finely punctate, length of malar space 2.2 �� basal width of mandible (Fig. 2F). Mesosoma. Length of mesosoma 1.3 �� its height; pronotum finely reticulate-rugose; mesoscutum evenly convex, reticulate-rugose, more strongly and coarsely rugose postero-medially; scutellum punctate medially, rugose laterally, more or less protruding above level of mesoscutum; scutellar suture comparatively deep and with 4 carinae; mesopleuron coarsely reticulate-rugose; propodeum coarsely reticulate-rugose with transversal carina and four blunt tubercles (Fig. 2B). Wings. Length of fore wing 2.5 �� its width; length of marginal cell 0.9 �� pterostigma; vein 2-Rl short (Fig. 1); r: 3-SR: SRl = 1: 1: 6; SRl complete and straight; parastigma not or weakly swollen; 1-CUl: 2-CUl = 3: 7; vein CUlb short (Fig. 2A). Legs. Hind соха completely smooth and setose; hind femur robust, length of hind femur, tibia and basitarsus 3.2, 4.5 and 6.4 �� their maximum width, respectively; length of hind tibial spurs 0.5 �� hind basitarsus (Fig.2I). Metasoma. Length of carapace 2.5 �� its maximum width in dorsal view (Fig. 2E); third tergite of carapace almost straightly narrowed, longitudinally densely reticulate-rugose; apex of carapace truncate and narrow in dorsal view, with a wide ventral lamella in lateral view (Fig. 2D); apex of carapace deeply incurved, about one fourth of total length of carapace. Colour. Black; six basal antennomeres yellowish-brown, remainder of antennomeres dark brown; palpi light yellow; mandible brown except black basally; pterostigma and most of veins blackish brown, veins of basal half of wing light yellow; parastigma light yellow; carapace yellowish in basal 1/3; legs mainly yellowish-brown except dark brown apex of hind tibia and all telotarsi black. Male. Length of body 3.0 mm, similar to female, but differs in having 23���26 antennomeres; length of metasoma 2.7 �� its maximum width in dorsal view (Fig. 3E); carapace with a small apical opening filled by white setae (Fig. 3J). Biology. Unknown. Distribution. Oriental China (Yunnan, Taiwan, Hainan). Etymology. Named after its special metasoma: mirabilis is Latin for wonderful and strange, venter is Latin for belly.
