Diagnosis. Clistopyga lobulata may be distinguished easily from all other species of the C. calixtoi species group by the following combination of characters: anterior half of median lobe of mesoscutum prominent ( Figs 30B, 30C ), separated from posterior half by a slight transverse depression ( Fig. 30C ); pronotum orange and black without white marks ( Fig. 30B ). metapleuron entirely black ( Fig. 30E ); propodeum with narrow lateral white marks (e.g. Figs 16D , 22G ); metasoma black, tergites without posterior defined white marks ( Figs 30F, 30G ).

Description. Female: Body length 8.8 mm. Fore wing length 6.9 mm.

Head ( Figs 30A–B, 30D, 30E ). In dorsal view, slightly narrowed behind eyes. Gena smooth and shiny with uniformly sparse setiferous punctures, in dorsal view 0.4× as long as eye, in frontal view moderately constricted below eyes, with straight profile.Frons and vertex smooth and shiny, with very isolated setiferous punctures.Posterior ocellus separated from eye 1.21× its maximum diameter. Distance between hind ocelli 0.98× maximum diameter of posterior ocellus. Hypostomal carina not lamelliform behind mandible. Face with fine and dense setiferous punctures, distance between punctures more than twice the diameter of punctures. Clypeal suture slightly curved. Clypeus 1.92× as broad as medially long, distinctly convex in dorsal half, flat in ventral half, with apical margin slightly concave. Malar space 1.02× as long as basal mandibular width, with a granulate narrow subocular sulcus. Antenna with 24 flagellomeres, first flagellomere about 7.6× as long as wide.

Mesosoma ( Figs 30B–D, 30E ). Pronotum shiny, smooth, with fine and scattered setiferous punctures in dorsal posterior part. Epomia as strong and short carina at the bottom of the submarginal depression of pronotum. Mesoscutum entirely smooth and shiny, with fine and very sparse setiferous punctures; anterior half of median lobe prominent, separated from posterior half by a slight transverse depression. Notaulus moderately deep, reaching about 0.5 the length of mesoscutum. Mesopleuron smooth and shiny, with evenly sparse setiferous punctures on anterior and ventral part. Epicnemial carina strong, sinuous, its dorsal end slightly curved towards the back, ending at level of centre of pronotum. Metapleuron shiny, glabrous, except for some sparse setiferous punctures at posterior end, 2.88–2.90× as long as high. Submetapleural carina absent. Propodeum smooth and shiny, with evenly sparse fine setiferous punctures on anterior half of dorsal part and laterally, in dorsal view 1.57× as long as medially wide. Propodeal spiracle about 0.16 the length to anterior end of pleural carina. Hind leg with femur 3.80× as long as high, 1.13× as long as tibia. Fore wing with vein cu-a opposite to Rs & M; vein 2 rs-m about 0.23× as long as abscissa of M between 2 rs-m and 2 m-cu; abscissa of Cu 1 between 1 m-cu and Cu 1 a 1.58× as long as Cu 1 b. Hind wing with vein cu-a + first abscissa of Cu 1 between M and cu-a not angled, reclivous on ventral 0.3, vertical on dorsal 0.7; distal abscissa of Cu 1 absent.

Metasoma ( Figs 30F–H ). Tergite I 1.50× as long as posteriorly broad, smooth and shiny, with very sparse setiferous punctures laterally and posteriorly; spiracle near its anterior 0.4; lateromedian longitudinal carinae present at anterior 0.2 of tergite, weak; lateral longitudinal carinae present at posterior 0.3 of tergite, weak. Sternite I extending posteriorly about 0.4 the length of tergite. Tergite II 1.05× as long as posteriorly broad, with very shallow and dense setiferous punctures distance between punctures about its diameter; punctation of posterior tergites tending to be shallower. Ovipositor relatively slender, evenly up-curved at distal 0.35, 2.0× as long as hind tibia. Ovipositor sheath about 1.6× as long as hind tibia, ventral margin basally without denticles, length of setae on average 2.2–2.3× the sheath basal width.

Colouration ( Fig. 30 ). Head dusky white with apex of mandibles, sides of clypeal suture, narrow longitudinal stripe at middle of face, frons and vertex medially, gena except ventral part, and occipital region black; antenna brownish black, ventrally pallid proximally, pedicel and scape ventrally dusky white. Mesosoma with mesoscutum, anterior part of scutellum, dorsal half of pronotum, mesopleuron and mesosternum orange; propleuron, ventral half of pronotum, axillae, dorsal part of propodeum, metapleuron and metasternum, black; tegula, subalar prominence, posterior part of scutellum, postscutellum and sides of propodeum dusky white cream. Metasoma with tergites and sternite I entirely black; ovipositor dark brown; ovipositor sheath black. Anterior two pair of legs predominantly white cream, trochanters proximally black, femora and tibiae dorsally striped with black and tarsi infuscate; hind leg white with coxa laterally, ventrally and anteriorly, trochanter proximally, femur laterally and proximally, and tibia proximally and distally black; hind tarsal segments predominantly blackish. Wings hyaline, pterostigma blackish.

Male: Unknown.

Etymology. The specific name refers to the prominent median lobe of mesoscutum.
