Description. Holotype , female. MEASUREMENTS. Body length 6.5 mm , fore wing length 5 mm . BODY. Weakly shining and sparsely clothed in white setae ( Fig. 6 , 7 ), except for dorsal part of pronotum ( Fig. 7B, C ) and posterior propodeal areas which are polished and glabrous ( Fig. 7E ). HEAD. Antenna slender, 1.4 × as long as fore wing, with 33 flagellomeres, and a white subapical band ( Fig. 6 ). Scape 1.4 × as long as broad ( Fig. 7A ). First flagellomere 1.3 × longer than second and 1.45 × longer than third. Head evenly narrowed behind eyes, its width 1.5 × its length ( Fig. 7C ). Transverse eye diameter 1.2 of temple length (dorsally). Inner margins of eyes converging ventrally ( Fig. 7A ). Frons polished, and impunctate ( Fig. 7C ). Antennal sockets raised slightly above frons in profile ( Fig. 7B ). Anterior tentorial pits distinct and deep ( Fig. 7A ). Clypeus 0.7 × as high as wide, separated from face by a distinct impression, densely clothed in white setae ( Fig. 7A ), flat in profile ( Fig. 7B ). Its margin sharp, concave, protruding laterally as weak lateral lobes, medially concave, with a dense apical fringe of short, parallel, ventrally directed setae ( Fig. 7A ). Mandible strongly widened apically, crescent-shaped, its dorsal tooth hidden when the mandible is closed ( Fig. 7A ), its ventral tooth twisted anteriorly ( Fig. 7A, B, F ), and distinctly longer than dorsal tooth ( Fig. 7A ). Malar space short, 0.23 × basal mandible width ( Fig. 7A, F ). Occipital carina complete, joining hypostomal carina above posterior mandibular condyle. MESOSOMA. Pronotum elongate, shining, and with transverse striation ( Fig. 7B, C ). Epomia distinct ( Fig. 7D ). Mesopleuron densely setose, impunctate, and shagreened, striated in its lower part ( Fig. 7D ). Auxiliary carina that extends from anterior edge of mesopleuron joining epicnemial carina, dorsal portion of epicnemial carina curving anteriorly toward posterior edge of pronotum ( Fig. 7D ), forked at apex. Mesoscutum weakly shining, sparsely setose, impunctate, with lateral carina. Notauli strong. Scutellum rather convex and forming apical tooth. Postscutellum not convex, not forming apical tooth ( Fig. 7D ). Juxtacoxal carina absent ( Fig. 7D ). Propodeum impunctate, with carinae complete ( Fig. 7E ). Area basalis rather small, weakly defined by wrinkles (carinae absent), area superomedia 1.5 × its width ( Fig. 7E ). Spiracle of propodeum at an equal distance from pleural and lateral longitudinal carinae, joined to pleural carina by a transverse carina ( Fig. 7D ). Hind femur 7.4 × its height in its middle ( Fig. 6 ). Tarsal claw simple. Fore wing with vein 3rs-m absent, vein 2m-cu with two bullae, abscissa CU longer than 2cu-a ( Fig. 7I ). Hind wing with distal abscissae of Rs, CU and AA distinct, cu-a shorter than CU ( Fig. 7I ) METASOMA. Smooth, impunctate. T1 cylindrical ( Figs 7G, H ), its length 6 × its posterior width ( Fig. 7G ), ventrobasally convex ( Fig. 7H ). Glymma absent, spiracle at 0.4 ( Fig. 7H ). Ovipositor weakly upcurved, 0.8 × length of T1 ( Fig. 6 ). Ovipositor sheath upcurved. COLORATION. Black, except the following are marked with brown: flagellomeres (except flagellomeres 10– 16 white), hind tibia apically, T3–5, T6–7 (except hind margin); the following are marked with reddish-yellow: scape, hind tarsus, T1 basally; the following are marked with reddish-brown: flagellomeres 1-3, tips of mandibles, pronotum, tegula, hind tibia (except apically), T2–3; the following are marked with reddish: fore and middle legs, T1 apically; the following are marked with ivory: basal part of mandibles, palpi, narrow hind margin of T6–7.

Atopotrophos spiniger can be distinguished from all other Atopotrophos spp. by having 33 flagellomeres (less in all other species, except A. bubeng which has 35), a rather short malar space (0.23 × basal mandible width), scutellum forming apical tooth (other Atopotrophos spp. with scutellum not convex except A. bubeng ). From similar species described here, A. bubeng it differs by smaller body ( 10 mm in A. bubeng ), 33 flagellomeres ( 35 in A. bubeng ), longer malar space (0.23 × basal mandible width and in 0.15 A. bubeng ), not convex postscutellum (it is forming apical tooth in A. bubeng ), shorter area superomedia (2.1 × its width in A. bubeng , shorter T1 (length 7 × posterior width in A. bubeng , and longer ovipositor (0.6 of T 1 in A. bubeng ).
