( Figs 1A View FIGURE 1 , 2A View FIGURE 2 , 3 View FIGURE 3 , 8A View FIGURE 8 , 9 View FIGURE 9 )

Diagnosis. Clistopyga albovittata may be distinguished easily from all other species of the C. diazi species group by the head, mesosoma and metasoma entirely black with white cream marks ( Figs 1A View FIGURE 1 , 3 View FIGURE 3 ). Male, additionally, may be distinguished by the lower part of gena deeply concave below eyes ( Figs 9A, 9C View FIGURE 9 , arrows).

Description. Female: Body length 7.0– 9.7 mm (without ovipositor). Fore wing length 5.7–7.5 mm.

Head ( Figs 3 View FIGURE 3 A–C). In dorsal view, strongly narrowed behind eyes. Gena smooth and shiny with very sparse setiferous punctures, in dorsal view almost straight, 0.37–0.38× as long as eye ( Fig. 3B View FIGURE 3 ), in frontal view concave and moderately constricted below eyes ( Fig. 3C View FIGURE 3 ). Frons shiny, with two concavities just behind scapes, transversely strigose, with very isolated setiferous punctures. Vertex smooth and shiny, with very isolated setiferous punctures. Posterior ocellus separated from eye 1.14–1.4× its maximum diameter. Distance between hind ocelli 0.86–1.07× maximum diameter of posterior ocellus. Occipital carina complete. Face with dense setiferous punctures, distance between punctures about once or twice the diameter of punctures ( Fig. 3C View FIGURE 3 ). Clypeal suture strongly curved. Clypeus 1.87–2.1× as broad as medially long, almost flat, with apical margin straight. Clypeal tentorial pits very small and shallow, almost obliterated ( Fig. 3C View FIGURE 3 ). Malar space 1.1–1.22× as long as basal mandibular width, with a granulate wide stripe between eye and mandible. Antenna with 26–28 flagellomeres, first flagellomere 6.67–8.4× as long as wide.

Mesosoma ( Figs 2A View FIGURE 2 , 3 View FIGURE 3 A–B). Pronotum mostly smooth and shiny with setiferous punctures on posterior dorsal corner. Epomia present as a tubercle at anterior submarginal depression of the pronotum. Mesoscutum shiny, with relatively dense shallow setiferous punctures, much more dense on median lobe ( Fig. 3B View FIGURE 3 ). Notauli deep, reaching about 0.5 the length of mesoscutum. Mesopleuron shiny, with moderately dense setiferous punctures, except in posterior part under speculum ( Fig. 3A View FIGURE 3 ). Epicnemial carina strong, its dorsal end straight, reaching level of centre of pronotum. Metapleuron shiny, with setiferous punctures irregularly distributed, more dense in anterior part, less dense on posterior part and very isolated in central part, 2.33–2.5× as long as high. Submetapleural carina complete, weakly curved inwards posteriorly ( Fig. 2A View FIGURE 2 ). Propodeum very finely and tightly transversally strigose, tending to be strongly and irregularly strigose at groove separating propodeum and metapleuron ( Fig. 3A View FIGURE 3 ), lateral part with setiferous punctures; in dorsal view 1.15–1.3× as long as medially wide. Propodeal spiracle at groove separating propodeum and metapleuron, continuity of groove interrupted by spiracle ( Fig. 3A View FIGURE 3 ). Hind leg with femur 3.61–3.67× as long as high, 1.08–1.18× as long as tibia. Fore wing with vein cu-a opposite Rs & M; vein 2 rs-m 0.3–0.8× 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 1.9–2.2× as long as Cu 1 b. Hind wing with vein cu-a 0.25–0.47× as long as abscissa of Cu 1 between M and cu-a; vein cu-a reclivous; first abscissa of Cu 1 inclivous; distal abscissa of Cu 1 present, weakly pigmented.

Metasoma ( Figs 3 View FIGURE 3 D–F). Tergite I 1.12–1.36× as long as posteriorly broad ( Fig. 3E View FIGURE 3 ), very finely and tightly strigose-granulate transversally at lateral basal parts, anterior dorsal concavity smooth and shiny, posteriorly densely punctate, spiracle near its basal 0.35 ( Fig. 3F View FIGURE 3 ); lateromedian longitudinal carinae absent, lateral longitudinal carinae very weakly insinuated anteriorly and posteriorly. Sternite I extending back 0.35–0.42 the length of tergite ( Fig. 3F View FIGURE 3 ). Tergite II 0.89–0.91× as long as posteriorly broad ( Fig. 3E View FIGURE 3 ), with dense deep punctures, distance between punctures about once its diameter; rest of tergites progressively more shallowly punctate. Ovipositor matt, evenly up-curved at distal 0.35 ( Fig. 3F View FIGURE 3 ), 2.0–2.25× as long as hind tibia. Ovipositor sheath 1.64–1.75× as long as hind tibia, length of setae on average 1.25–1.5× the sheath basal width. Ventral margin of ovipositor sheath basally with numerous small denticles ( Fig. 3D View FIGURE 3 ).

Colouration ( Figs. 1A View FIGURE 1 , 3 View FIGURE 3 ). Body mostly black. Head with facial, frontal and vertical orbits, mandibles except apex and a triangular mark on ventral part of gena next to the eye, white ( Figs 3 View FIGURE 3 A–C); basal part of palpi and dorsal part of clypeus, yellow; distal part of palpi and ventral part of clypeus orange; flagellum dark brown. Mesosoma with anterior medial part and lateral dorsal part of pronotum, tegula, subalar prominence, a small spot at anterior upper end of epicnemial carina, mesepimeron, lateral wide longitudinal stripes on propodeum, two dorsal stripes on mesonotum, widely interrupted by notauli, sometimes absent anteriorly, rarely a hue on lateral lobes of mesoscutum, lateral marks flanking the scuto-scutellar groove and apex of scutellum and postscutellum, white ( Figs 3 View FIGURE 3 A–B). Metasoma with lateral marks at base of tergite I and posterior margins of tergites I–VI white ( Figs 3 View FIGURE 3 E–F); ovipositor reddish; ovipositor sheaths dark brown ( Fig. 3F View FIGURE 3 ). Fore and mid legs mostly orange with a dorsal stripe on tibiae an all tarsi, and base of mid trochanter, dark brown. Hind leg mainly orange with a dorsal stripe on coxa and lateral mid parts of tibia, white; lateral parts of coxa, base of trochanter and femur, tibia and tarsi dark brown. Wings hyaline, pterostigma brown ( Fig. 1A View FIGURE 1 ).

Head ( Figs 9 View FIGURE 9 A–C). In dorsal view, moderately narrowed behind eyes. Gena, in dorsal view, somewhat rounded, 0.44–0.53× as long as eye ( Fig. 9B View FIGURE 9 ), in frontal view deeply concave below eyes ( Fig. 9A View FIGURE 9 ). Posterior ocellus separated from eye 1.1–1.25× its maximum diameter. Distance between hind ocelli 1.0–1.25× the maximum diameter of posterior ocellus. Face with moderately dense setiferous punctures, distance between punctures about once or twice centrally, and about four times laterally, the diameter of punctures. Clypeus 1.67–1.75× as broad as medially long. Clypeal fovea very small or absent. Malar space 1.05–1.2× as long as basal mandibular width. Antenna with 22–25 flagellomeres, first flagellomere 6.25–6.60× as long as wide.

Mesosoma ( Figs 9 View FIGURE 9 D–E). Epomia short and straight, only shortly present at anterior submarginal depression of the pronotum. Metapleuron with setiferous punctures, much more scattered than in female, 2.27–2.33× as long as high ( Fig. 9D View FIGURE 9 ). Propodeum in dorsal view 1.39–1.43× as long as medially wide. Hind leg with femur 4.42–4.93× as long as high, 0.81–0.88× as long as tibia. Fore wing with vein 2 rs-m 0.27–0.32× 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 1.7–2.7× as long as Cu 1 b. Hind wing with vein cu-a 0.3–0.35× as long as abscissa of Cu 1 between M and cu-a.

Metasoma ( Figs 9 View FIGURE 9 F–G). Tergite I 1.5–1.84× as long as posteriorly broad ( Fig. 9F View FIGURE 9 ). Lateromedian longitudinal carinae reaching about 0.2 of length of tergite. Sternite I extending back 0.38–0.42 the length of tergite ( Fig. 9G View FIGURE 9 ). Tergite II 1.25–1.33× as long as posteriorly broad ( Fig 9F View FIGURE 9 ).

Colouration ( Figs 8A View FIGURE 8 , 9 View FIGURE 9 ). As in female but hind coxa black with dorsal white stripe and femur more extensively tinged with dark brown.

Other features as in female.

Etymology: The specific name “ albovittata ” derives from the combination of the Latin words “ albus ” that means white and “ vittatus ” that means banded (vitta, band), in reference to the black body banded with white.
