Diagnosis. Clistopyga isabellae may be distinguished easily from all other species of the C. calixtoi species group by the following combination of characters: genal orbits white cream, dorsal part much more narrow than ventral part ( Figs 22A, 22D View FIGURE 22 , 23A View FIGURE 23 ); mesopleuron mostly dark orange with dorsal anterior part black; subalar prominence and a mid anterior spot (divided by black epicnemial carina) white cream ( Figs 22D View FIGURE 22 , 23D View FIGURE 23 ); metapleuron black and dark orange ( Fig. 22G View FIGURE 22 , 23C View FIGURE 23 ); propodeum with lateral white cream mark ( Figs 22G View FIGURE 22 , 23C View FIGURE 23 ); metasoma entirely dark orange, without posterior defined white or yellow marks on tergites ( Figs 22A, 22F View FIGURE 22 , 23A, 23F View FIGURE 23 ); epomia as a very short inconspicuous carina at the bottom of the submarginal depression of pronotum ( Fig. 22C View FIGURE 22 , arrow); submetapleural carina extended at most on anterior 0.6 of metapleuron ( Fig. 22G View FIGURE 22 , 23C View FIGURE 23 ). Additionally, female has ovipositor stout, abruptly up curved at distal 0.3 ( Fig. 22I View FIGURE 22 ). Male has gena in frontal view straight or slightly convex in profile, without any traces or longitudinal concavity posterior to mandible base ( Fig. 23B View FIGURE 23 ).

Description. Female: Body length 8.8–12.3 mm. Fore wing length 6–9 mm.

Head ( Figs 22A–B, 22D–E View FIGURE 22 ). In dorsal view, moderately narrowed behind eyes. Gena shiny with very sparse setiferous punctures, in dorsal view almost straight, about 0.3× as long as eye, in frontal view moderately constricted below eyes, straight. Frons and vertex smooth and shiny, with very isolated setiferous punctures. Posterior ocellus separated from eye once its maximum diameter. Distance between hind ocelli 0.75–0.80× maximum diameter of posterior ocellus. Hypostomal carina not lamelliform behind mandible. Face with fine and very sparse setiferous punctures, distance between punctures more than twice the diameter of punctures. Clypeal suture moderately curved. Clypeus 1.6–1.7× as broad as medially long, weakly convex, dorsally, flat ventrally, ventral margin straight centrally. Malar space 0.85–0.9× as long as basal mandibular width, with a granulate narrow and deep subocular sulcus. Antenna with 28–32 flagellomeres, first flagellomere 6.35–6.7× as long as medially wide.

Mesosoma ( Figs 22A, 22C–E, 22G–H View FIGURE 22 ). Pronotum smooth and shiny. Epomia as a very short inconspicuous carina at the bottom of the submarginal depression of pronotum. Mesoscutum shiny, with very sparse shallow setiferous punctures, somewhat denser on median lobe; anterior half of median lobe not conspicuously prominent, confluent with posterior half. Notaulus deep, reaching about 0.5 the length of mesoscutum. Mesopleuron shiny, with sparse setiferous punctures, except at mid and dorsal posterior part. Epicnemial carina strong, its dorsal end straight, ending at level of centre of pronotum. Metapleuron shiny, with very sparse setiferous punctures posteriorly, 2.6– 2.65× as long as high. Submetapleural carina weak, extended on anterior 0.6 of metapleuron. Propodeum smooth and shiny with sparse very fine setiferous punctures laterally, in dorsal view 1.0–1.2× as long as medially wide. Propodeal spiracle relatively small, its internal diameter 0.1–0.12 the length to anterior end of pleural carina. Hind leg with femur 4.3–4.4× as long as high, 1.0–1.2× as long as tibia. Fore wing with vein cu-a opposite to Rs & M; vein 2 rs-m 0.4–0.45× 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 1.65–1.8× as long as Cu 1 b. Hind wing with vein cu-a 0.5–0.6× 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, pigmented.

Metasoma ( Figs 22A, 22F, 22I View FIGURE 22 ). Tergite I 1.3–1.4× as long as posteriorly broad, smooth and shiny, with lateral and posterior setiferous punctures, spiracle near its anterior 0.3; lateromedian longitudinal carinae and lateral longitudinal carinae absent. Sternite I extending posteriorly 0.45–0.55 the length of tergite. Tergite II 0.95–1.1× as long as posteriorly broad, with dense fine and relatively deep punctures, distance between punctures less than its diameter; remaining tergites same macrosculpture. Ovipositor stout, abruptly up-curved at 0.3 distal, 1.85–2.0× as long as hind tibia. Ovipositor sheath 1.6–1.7× as long as hind tibia, ventral margin basally without denticles, length of setae on average 2.2–2.55× the sheath basal width.

Colouration ( Fig. 22 View FIGURE 22 ). Head mostly white cream with apex of mandibles, clypeal suture, subocular sulcus, wide longitudinal stripe at middle of face, frons and vertex medially, posterior part of gena and occipital region, dark brown to black; antenna brown, ventrolaterally lighter at base. Mesosoma mostly dark orange; propleuron and pronotum mostly, mid posterior part and periphery of mesoscutum, notauli, scuto-scutellar groove, axillae, propodeum mostly, epicnemium, antero-dorsal part of mesopleuron and ventral part of metapleuron, dark brown to black; propleuron laterally, dorsal lateral and ventral anterior band on pronotum, tegula, alar joint, subalar prominence, a mid spot at anterior part of mesopleuron and posterior dorsal part of epimeron, divided by dark epicnemial carina, mesepisternum, two longitudinal stripes on mesoscutum, interrupted by dark notauli, lateral and posterior part of scutellum, postscutellum, lateral parts of propodeum, white cream. Metasoma mostly dark orange, sternite I, anterior dorsal part of tergite I, lateral posterior spots on tergite II dark brown to black. Lateral anterior spots on tergite I and posterior margin of tergites I–II finely yellowish white or yellow cream; ovipositor dark orange; ovipositor sheaths dark brown. Legs predominantly white cream; front and mid leg with trochanter ventrally, dorsal narrow stripes on femur and tibia (medially interrupted), and tarsi brown; hind leg with anterior and posterior wide mark on coxa, trochanter basally, base, anterior, posterior and ventral streps, basal and distal part of tibia, and all tarsi except base, brown. Wings hyaline, pterostigma brown.

Male: Body length 6.2–9.2 mm. Fore wing length 4.0– 6.5 mm.

Head ( Figs 23A–B, 23D–E View FIGURE 23 ). Gena in dorsal view slightly rounded, 0.3–0.35× as long as eye, in frontal view strongly constricted below eyes, straight. Posterior ocellus separated from eye 0.8–1.0× its maximum diameter. Distance between hind ocelli 0.8–1.0× maximum diameter of posterior ocellus. Clypeus 1.75–2.0× as broad as medially long. Malar space 0.75–0.80× as long as basal mandibular width. Antenna with 24–28 flagellomeres, first flagellomere 5.5–6.5× as long as wide.

Mesosoma ( Figs 23A, 23C–E View FIGURE 23 ). Metapleuron, 2.1–2.35× as long as high. Hind leg with femur 4.25–4.4× as long as high Fore wing vein 2 rs-m 0.35–0.4× 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 1.2–1.4× as long as Cu 1 b. Hind wing with vein cu-a 0.4–0.45× abscissa of Cu 1 between M and distal abscissa of Cu 1; vein cu-a slightly reclivous, first abscissa of Cu 1 vertical; distal abscissa of Cu 1 insinuated distally.

Metasoma ( Figs 23A, 23F View FIGURE 23 ). Tergite I 1.75–1.9× as long as posteriorly broad. Tergite II 1.35–1.45× as long as posteriorly broad, punctures shallower.

Colouration ( Fig. 23 View FIGURE 23 ).As in female, but tergites I–IV with laterodorsal posterior black spots. Hind femur without ventral brown stripe.

Other features as in female.
