7. Clistopyga brevicaudata Bordera & Palacio, sp. nov. (Figs 11, 52A, Appendix I) Diagnosis. Clistopyga brevicaudata may be easily distinguished from all other species of the C. calixtoi species group by the following combination of characters: mesoscutum brownish black with two longitudinal orange stripes (Fig. 11E); pronotum black, dorsally narrowly yellow banded (Fig. 11D); propodeum black with relatively narrow lateral longitudinal white bands (Fig. 11F); metasoma dark brown without posterior defined white or yellow marks on tergites (Fig. 11I); epomia strong and short, vertical (Fig. 11C, arrow); fore wing with vein cu-a clearly distal to Rs & M (Fig. 11G); propodeum densely rugulose punctate above pleural sulcus (Fig. 11F); ovipositor relatively short, 1.30–1.35× as long as hind tibia (Fig. 11A, 11F); ovipositor sheath without denticles on ventral margin, 1.10–1.15× as long as hind tibia (Fig. 11J). Description. Female: Body length about 6.2 mm. Fore wing length about 4.5 mm. Head (Figs 11A, 11B, 11D–E). In dorsal view, moderately narrowed behind eyes. Gena shiny with very sparse setiferous punctures, in dorsal view slightly rounded, about 0.4× as long as eye, in frontal view, moderately constricted below eyes, weakly convex. Frons and vertex smooth and shiny, with sparse setiferous punctures. Posterior ocellus separated from eye 1.15–1.2 its maximum diameter. Distance between hind ocelli 1.35–1.4× maximum diameter of posterior ocellus. Hypostomal carina not lamelliform behind mandible. Face with moderately deep, fine and dense punctures, distance between them about 1.0 its diameter. Clypeal suture moderately curved. Clypeus 1.85× as broad as medially long, weakly convex with few isolated setiferous punctures dorsally, somewhat concave and smooth ventrally, ventral margin straight medially. Malar space 1.2× as long as basal mandibular width, with a granulate subocular sulcus progressively wider towards the mandibular basis. Antenna with 23 flagellomeres, first flagellomere about 6.1× as long as medially wide. Mesosoma (Figs 11A, 11C–H). Pronotum smooth and shiny with setiferous punctures on dorsal part and posterior corner. Epomia strong and short, vertical. Mesoscutum shiny, with moderately deep and dense setiferous punctures, much 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 and shallow setiferous punctures, about 2.2× as long as high. Submetapleural carina strong, extended on anterior 0.5 of metapleuron. Propodeum shiny, shallowly rugulose punctate, macrosculpture conspicuously stronger dorsally to the pleural sulcus, in dorsal view 1.10–1.15× as long as medially wide. Propodeal spiracle about 0.16 the length to anterior end of pleural carina. Hind leg with femur about 3.9× as long as high, about 0.95× as long as tibia. Fore wing with vein cu-a clearly distal to Rs & M; 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 1.65× as long as Cu 1 b. Hind wing with vein cu-a + abscissa of Cu 1 between M and cu-a straight, vertical; distal abscissa of Cu 1 absent. Metasoma (Figs 11A, 11I–J). Tergite I 1.2–1.25× as long as posteriorly broad, shiny, shallowly rugulose punctate, dorsal posterior part tending to be shallowly transversally strigose punctate, spiracle at its anterior 0.3; lateromedian longitudinal carinae strong, present at anterior 0.3 of tergite; lateral longitudinal carinae weakly present on posterior third of tergite. Sternite I extending posteriorly about 0.4 the length of tergite. Tergite II about 0.9× as long as posteriorly broad, with shallow and coarse adjacent punctures; punctation of posterior tergites tending to be shallower. Ovipositor mat, gently and evenly up-curved at posterior 0.5, 1.30–1.35× as long as hind tibia. Ovipositor sheath 1.10–1.15× as long as hind tibia, ventral margin basally without denticles, length of setae on average 1.9–2.0× the sheath basal width. Colouration (Fig. 11). Head mostly black with base of mandibles, palpi, clypeus, facial, frontal and vertical orbits narrowly, and rounded spot on ventral part of gena, white cream; antenna dark brown, pedicel, annellus and first and second flagellomeres, laterally white cream. Mesosoma mostly dark brown; mesosternum, mesopleuron except speculum, metapleruon mostly, two longitudinal stripes on mesonotum, scuto-scutellar grove, and anterior part of scutellum, orange; ventral spot on propleuron, dorsal narrow lateral band on pronotum, subalar prominence, tegula, alar joint, posterior part of scutellum, postscutellum, mesepisternum, lateral longitudinal stripes on propodeum, white cream. Metasoma dark brown to black with orange lateral diffuse stripes on tergite I; ovipositor orange; ovipositor sheaths dark brown. Anterior and mid legs predominantly white cream; posterior spot and dorsal triangular mark on coxa, spot on dorsal basal part o trochanters, dorsal and ventral stripes on femur and tibia and distal part of tarsi brown; hind leg predominantly dark orange to brown, with dorsal and ventral stripes and subdistal anterior spot on coxa, apex of trochanter, three stripes and subdistal part of femur, mid part of tibia and base of tarsi white cream. Wings hyaline, pterostigma blackish brown. Male: Unknown. Etymology. The specific name refers to the relatively short ovipositor that characterizes this species. Type material (1 ♀). Holotype. Perú: 1 ♀, Cuzco, 24-XI-1965, H. M. Townes (EMUS). Distribution. Peru (Fig. 52A, Appendix I).
