Frons polished, impunctate. Antennal sockets raised above frons in profile ( Fig. 3B View FIGURE 3 ). Anterior tentorial pits distinct and deep ( Fig. 3A View FIGURE 3 ). Clypeus 0.7 × as high as wide, separated from face by a distinct impression, densely clothed with white setae ( Fig. 3A View FIGURE 3 ), flat in profile ( Fig. 3B View FIGURE 3 ). Its margin sharp, truncate, laterally produced as small lobes, medially with a dense apical fringe of short, parallel, yellowish, ventrally directed setae ( Fig. 3A View FIGURE 3 ). Mandible strongly widened apically, crescent-shaped, its dorsal tooth hidden when the mandible is closed ( Fig. 3A View FIGURE 3 ), its ventral tooth twisted anteriorly ( Fig. 3B, I View FIGURE 3 ), and 1.5 × length of dorsal tooth ( Fig. 3A View FIGURE 3 ). Malar space very short, 0.15 × basal mandible width ( Fig. 3A, I View FIGURE 3 ). Occipital carina complete, joining hypostomal carina at a distance from posterior mandibular condyle of about 2.0 × basal width of mandible.

MESOSOMA. Pronotum elongate, shining, with transverse striation ( Fig. 3D View FIGURE 3 ). Epomia distinct ( Fig. 3D View FIGURE 3 ). Mesopleuron densely setose, impunctate, shagreened and striated in its lower part ( Fig. 3D View FIGURE 3 ). Auxiliary carina which extends from anterior edge of mesopleuron joining epicnemial carina, dorsal portion of epicnemial carina curving anteriorly toward posterior edge of pronotum ( Fig. 3D View FIGURE 3 ), and forked at apex. Postpectal carina complete, intersected by several short longitudinal carinae. Mesoscutum weakly shining, sparsely setose, impunctate, with lateral carina ( Fig. 3F View FIGURE 3 ). Notauli strong, anteriorly broad, the remainder narrowly deep, curved and joining medioposteriorly, with some internal rugosity ( Fig. 3F View FIGURE 3 ). Scutellum rather convex, forming an apical tooth, with lateral carina ( Figs 3D View FIGURE 3 1 View FIGURE 1 , F). Postscutellum convex, forming an apical tooth ( Figs 3D View FIGURE 3 2 View FIGURES 2 ). Juxtacoxal carina absent ( Fig. 3D View FIGURE 3 ). Propodeum impunctate, with carinae complete ( Fig. 3E View FIGURE 3 ). Lateral longitudinal and posterior transverse carina forming a small tooth ( Figs 3D, E View FIGURE 3 ). Area basalis rather small, pentagonal, area superomedia 2.1 × its width ( Fig. 3E View FIGURE 3 ). Spiracle of propodeum at an equal distance from pleural and lateral longitudinal carinae, joined to pleural carina by a transverse carina ( Fig. 3D View FIGURE 3 ). Length of hind femur 6.7 × its width medially ( Fig. 2 View FIGURES 2 ). Outer spur of hind tibia 0.75 × length of inner spur ( Fig. 2 View FIGURES 2 ). Tarsal claw simple ( Fig. 3G View FIGURE 3 ). Fore wing with vein 3rs-m absent, vein 2m-cu with two bullae, abscissa of CU longer than 2cu-a ( Fig. 3L View FIGURE 3 ). Hind wing with distal abscissa of Rs, M, CU and AA distinct, cu-a shorter than CU ( Fig. 3L View FIGURE 3 )

METASOMA. Smooth, impunctate. T1 cylindrical ( Fig. 3J, K View FIGURE 3 ), its length 7 × its posterior width ( Fig. 3J View FIGURE 3 ), convex ventrobasally ( Fig. 3K View FIGURE 3 ). Glymma absent, spiracle at 0.5 ( Fig. 3K View FIGURE 3 ). S1 fused with T1. Ovipositor weakly upcurved, 1.1 × as long as apical height of metasoma ( Fig. 3H View FIGURE 3 ), or 0.6 of T1 ( Fig. 2 View FIGURES 2 ). Its ventral valve with weak sclerotization at base extending to midpoint ( Fig. 3H View FIGURE 3 ). Ovipositor sheath upcurved. Egg exposed, with elongate apical stalk ( Fig. 3H View FIGURE 3 ).

COLORATION. Mostly black, except for: white antennal flagellomeres 11–15, and the following are marked with ivory: basal part of mandible, palpi, fore coxa apically, fore and middle trochanters, hind tarsus, T6–7 dorsally; the following are marked with yellowish-brown: pronotum dorsally, tegula, fore and middle legs, T1 anteriorly, T3; the following are marked with reddish-brown: basal flagellomeres, scape, hind coxa, hind femur, hind tibia except apically; the following are marked with brown: hind tibia apically, T1 posteriorly, T2, T4–5, T6–7 laterally, S5–6.

Male. Unknown.

Hosts. Unknown.

Distribution. Yunnan (SW China).

Diagnosis. Atopotrophos bubeng can be distinguished from all other Atopotrophos spp. by a combination of: 35 flagellomeres (fewer in all other species), a very short malar space (0.15 × basal mandible width), both scutellum and postscutellum forming an apical tooth. The most similar species, A. spiniger , differs from the new species in having a smaller body size (6.5 mm in A. spiniger and 10mm in A. bubeng ( Fig. 6 View FIGURE 6 )), a lower number of flagellomeres, (33 in A. spiniger and 35 in A. bubeng ( Fig. 6 View FIGURE 6 )), a longer malar space (0.23 × basal mandible width in A. spiniger and 0.15 in A. bubeng ( Fig. 7A, B View FIGURE 7 )), postscutellum not forming an apical tooth (present in A. bubeng ) ( Fig. 7D View FIGURE 7 )), defined carinated area basalis (weakly defined by wrinkles in A. spiniger ), a shorter area superomedia (1.5 × its width in A. spiniger and 2.1 × its width in A. bubeng ( Fig. 7E View FIGURE 7 )), length of T1 shorter (6 × posterior width in A. spiniger and 7 × posterior width in A. bubeng ( Fig. 7G View FIGURE 7 )), and a longer ovipositor (0.8 of T 1 in A. spiniger and 0.6 of T 1 in A. bubeng ( Fig. 6 View FIGURE 6 )).
