Diagnosis.

This species can be distinguished from all other species of the C. henryi species-group by the combination of the following characteristics: 1) ovipositor straight; 2) submetapleural carina incomplete, only present at anterior 0.2; 3) hind wing with distal abscissa of CU well pigmented; 4) clypeus 1.3–1.7 × as broad as medially long; 5) metapleuron reddish orange with ventral part blackish and propodeum blackish in the center, lateral part whitish; 6) tergites II – VI with posterolateral black to blackish spots posterior to transverse white bands.; 7) female with ovipositor 2.2 × as long as hind tibia; 8) sheath about 2.0 × as long as hind tibia, length of setae on average 2.0 × the sheath basal width.

Metapleuron shiny, almost glabrous, except for some sparse setiferous punctures at posterior part, [1.81] 1.8–1.9 × as long as deep. Submetapleural carina incomplete, present at anterior about [0.2]. Propodeum smooth and shiny, with sparse and fine setiferous punctures laterally, in dorsal view [1.2] 1.1–1.2 × as long as medially wide. Propodeal spiracle joining groove separating propodeum and metapleuron, groove partially interrupted by spiracle. Hind leg with femur [6.0] 4.0–6.0 × as long as deep and [0.88] 0.85–0.9 × as long as tibia.

Hind wing with vein CU about [0.5] × as long as abscissa of CU between M and cu-a; vein cu-a reclivous; abscissa of CU vertical and straight; distal abscissa of CU well pigmented. Metasoma. Tergite I [1.66] 1.4–1.66 × as long as posteriorly broad, smooth and shiny, with fine and relatively dense setiferous punctures laterally; spiracle near its basal [0.4]; lateromedian longitudinal carinae weak, reaching about [0.17] 0.15–0.20 of length of tergite; lateral longitudinal carinae weak, reaching about [0.33] of the length of tergite. Sternite I extending back [0.46] 0.4–0.5 of the length of tergite. Tergite II [1.16] 1.1–1.3 × as long as posteriorly broad, central region shiny, with very fine and very sparse setiferous punctures; anterolateral part weakly rugulose, rest of tergites shiny, progressively more densely and strongly punctate. Ovipositor [2.2] × as long as hind tibia, sheath about [2.0] × as long as hind tibia, length of setae on average [2.0] × the sheath basal width.

Coloration. Head black with, frontal, facial orbits widely and vertical orbits and mouth parts, except apex of mandibles, white; antenna with scape and pedicel black, widely white on the outer side, flagellomeres brown, the basal ones pallid on the outer side. Mesosoma mostly reddish orange, upper and lower parts of pronotum, propleuron posteriorly, tegula, subalar prominence, posterior part of mesopleuron, scutellum posteriorly, metanotum dorsally and longitudinal bands laterally of propodeum whitish; propleuron anteriorly, basal part of metanotum and median part of propodeum black. Metasoma mostly black, with transverse white bands on tergites I – VI and whitish areas on anterolateral corners of tergites I – III; tergites II – VI with posterolateral black to blackish spots posterior to transverse white bands. Fore and mid legs predominantly whitish, middle coxae laterally and proximally black, middle trochanters proximally black, femora and tibia dorsally striped with black and tarsi infuscate; hind leg white, coxa laterally and proximally black, trochanter proximally black, femur dorsally and externally striped with black, tibia slightly infuscate, dorsally striped with black, tarsi infuscate.

Etymology.

The specific name “ teresopolitana ” is an adjective referring to the type locality, Teresópolis, Rio de Janeiro, Brazil. The toponym, meaning “ city of Teresa, ” combines the personal name Teresa (of Greek origin) with the Greek word πόλις (pólis, “ city ”).

Distribution.

Brazil (Fig. 6 ).

Remarks.

Clistopyga teresopolitana sp. nov. resembles C. henryi Gauld, 1991 mainly by body coloration (reddish-orange in general), submetapleural carina not complete, and ovipositor straight, not decurved. However, it clearly differs from C. henryi by its shorter ovipositor (2.2 × as long as the hind tibia, ovipositor 2.7–2.8 × as long as hind tibia in C. henryi ).
