Abstract: Clistopyga magninsula Higa & Penteado-Dias, sp. nov. Figs 2A–H Diagnosis. Clistopyga magninsula sp. nov. can be distinguished from other species included in the C. calixtoi species group by the combination of the following characters: body mostly orange, white, dark brown and black (Fig. 2A); face white, with a narrow longitudinal brown stripe in the middle part, stronger in the center (Fig. 2E); metasoma dark brown, with dorsolateral white marks on posterior corners of tergites I–VI, black bands on the posterior part of tergites II–IV. Clypeal suture strongly curved; clypeus 1.87× as broad as medially long, with apical margin bilobed (Fig. 2E); malar space 0.9× as long as basal mandibular width, with narrow sulcus between eye and mandible, evanescent towards mandibular base, forming a wide triangular granulate area; gena in frontal view straight and moderately constricted below eyes; occipital carina strong and complete, not forming a flange dorsomedial (Fig. 2F); epomia present as a tubercle strong and short at anterior submarginal depression of the pronotum; epicnemial carina weak, its dorsal end slightly curved backwards, reaching a little below center of pronotum; submetapleural carina present in the anterior part 0.5 (Fig. 2B); propodeum smooth and shiny, not rugulose (Fig. 2B–C); sternite I extending back 0.7 of length of tergite; hind wing with vein cu-a 0.5× as long as abscissa of Cu 1 between M and cu-a (Fig. 2D); distal abscissa of Cu 1 weakly pigmented. Description. Female. Body length 8.5 mm. Fore wing length 5.5 mm. Head (Figs 2E–F). In dorsal view, moderately narrowed behind eyes. Gena smooth and shiny with very sparse setiferous punctures, in dorsal view 0.2× as long as eye, in frontal view straight and moderately constricted below eyes (Fig. 2E). Frons smooth and shiny, with sparse setiferous punctures. Vertex smooth and shiny, with very isolated setiferous punctures. Posterior ocellus separated from eye 1.0× its maximum diameter. Distance between posterior ocelli 1.1× maximum diameter of posterior ocellus. Occipital carina strong and complete, not forming a flange dorsomedial (Fig. 2F). Face with fine and moderately scattered setiferous punctures, distance between punctures more than 2.0× the diameter of punctures (Fig. 2E). Clypeal suture strongly curved. Clypeus 1.87× as broad as medially long, weakly convex in dorsal half and slightly concave in ventral half, with apical margin bilobed. Clypeal tentorial pits conspicuous. Malar space 0.9× as long as basal mandibular width, with narrow sulcus between eye and mandible, evanescent towards mandibular base, forming a wide triangular granulate area. Antenna with 27 flagellomeres, first flagellomere 4.7× as long as wide. Mesosoma (Figs 2A–C). Pronotum smooth and shiny with fine and scattered setiferous punctures on upper posterior part. Epomia present as a tubercle strong and short at anterior submarginal depression of the pronotum. Mesoscutum shiny, with relatively dense shallow setiferous punctures, much more dense on median lobe. Notauli deep, reaching about 0.44× length of mesoscutum. Mesopleuron shiny, with relatively dense setiferous punctures, except in posterior part; punctures denser towards the ventral part. Epicnemial carina weak, its dorsal end slightly curved backwards, reaching a little below the center of pronotum. Metapleuron shiny, almost glabrous, 2.5× as long as high (Fig. 2B). Submetapleural carina present in the anterior part 0.5. Propodeum smooth and shiny, not rugulose (Figs 2B–C), with sparse and fine setiferous punctures except posterior part; in dorsal view 0.94× as long as medially wide. Propodeal spiracle round at groove separating propodeum and metapleuron, continuity of groove interrupted by spiracle. Hind leg with femur 3.67× as long as deep, 0.94× as long as tibia. Fore wing with vein cu-a opposite Rs & M; vein 2 rs-m 0.4× 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 1.24× as long as Cu 1 b. Hind wing with vein cu-a 0.5× as long as abscissa of Cu 1 between M and cu-a (Fig. 2D); vein cu-a reclivous; first abscissa of Cu 1 reclivous and straight; distal abscissa of Cu 1 weakly pigmented. Metasoma (Figs 2A–C, G). Tergite I 1.63× as long as posteriorly broad (Fig. 2C), shiny, with fine setiferous punctures laterally and posteriorly, smooth on dorsal basal part, spiracle near its basal 0.3 (Fig. 2B); lateromedian longitudinal carinae strong, reaching 0.25 the length of tergite; lateral longitudinal carinae absent. Sternite I extending back 0.7 of length of tergite. Tergite II 1.28× as long as posteriorly broad (Fig. 2C), with moderately dense setiferous punctures, distance between punctures about 1.5× its diameter; rest of tergites with denser punctures. Ovipositor matt, evenly up-curved at distal 0.4, 2.1× as long as hind tibia (Fig. 2G). Ovipositor sheath 1.7× as long as hind tibia, length of setae on average 0.8–1.6× the sheath basal width. Ventral margin of ovipositor sheath basally without denticles at basal ventral margin. Colouration. Body mostly orange, white, dark brown and black (Fig. 2A). Head almost black, with frontal margin of eye, base of mandibles, clypeus and palpi white (Fig. 2E); antenna light brown, with ventral apical part of scape, ventral part of pedicel, ventral basal part of flagellomeres white. Face white, with a narrow longitudinal brown stripe in the middle part, stronger in the center. Propleuron white, with black spot anteriorly (Fig. 2A). Pronotum orange with collar and wide dorsolateral band white. Mesopleuron orange with white spots ventrally; tegula, scutellum, postscutellum, mesopleural suture and subalar prominence white. Metapleuron orange and metasternum black (Fig. 2B). Mesoscutum orange, with small longitudinal spots on the lateral lobes. Propodeum white, with black/dark brown stripe in the dorsomedial region and on the anterior and posterior margins. Wings hyaline, pterostigma brown (Fig. 2A). Fore leg white, with a dark brown dorsal stripe on femur, tibia and tarsus. Mid leg white, with base of trochanter, dorsal stripes on femur and tibia, and distal part of tarsomeres dark brown. Hind leg white, sides of coxa with brown spots, base of trochanter, basal and subapical of femur, basal and distal of tibia and distal of tarsomeres dark brown. Metasoma dark brown, with dorsolateral white marks on posterior corners of tergites I–VI, black bands on the posterior part of tergites II–IV. Ovipositor reddish brown. Ovipositor sheath dark brown. Comments. Clistopyga magninsula sp. nov. differs from C. maya González-Moreno & Bordera mainly due to the orange color of the pronotum (black in C. maya); face white, with a narrow longitudinal brown stripe in the middle part, stronger in the center (narrow brown stripe surrounding clypeus in C. maya); black bands on the posterior part of tergites II–IV (black bands absent in C. maya); gena in frontal view straight and moderately constricted below eyes (strongly constricted in C. maya); malar space 0.9× as long as basal mandibular width (1.2× in C. maya); epomia present (absent in C. maya); propodeum not rugulose (rugulose in C. maya); distal abscissa of Cu 1 weakly pigmented (absent in C. maya). Etymology. The specific name “ magninsula ” refers to the large Brazilian island on which it was collected. Type material. Holotype.
