Clistopyga angustipleura Bordera & Palacio & Herrera-Flórez 2025, sp. nov.

4. Clistopyga angustipleura Bordera & Palacio, sp. nov. (Figs 7, 53, Appendix I) Diagnosis. Clistopyga angustipleura may be distinguished from all other species of the C. calixtoi species group by the following combination of characters: genal orbits widely interrupted with brown or black (Fig. 7E); mesopleuron ventrally white cream (Figs 7A, 7D); metasoma with posterolateral well defined yellow marks on tergites, clearly separated from posterior rim (Figs 7F–G); epomia as a short carina at the bottom of the submarginal depression of pronotum (Fig. 7B); metapleuron about 2.5× as long as high (Figs 7D, 7H); submetapleural carina very weak, virtually extended on anterior 0.3 of metapleuron (Fig. 7H); gena, in frontal view, moderately constricted below eyes, with straight profile or slightly concave profile (Fig. 7C); clypeal suture moderately curved (Fig. 7C); hind femur about 3.5× as long as high. Description. Female: Body length about 9.7 mm. Fore wing length 6.6 mm. Head (Figs 7A–E). In dorsal view, strongly narrowed posteriorly to eyes. Gena shiny with very sparse setiferous punctures, in dorsal view straight, about 0.3× as long as eye, in frontal view moderately constricted below eyes, with straight profile. Frons and vertex smooth and shiny, with very isolated setiferous punctures. Posterior ocellus separated from eye 0.78× its maximum diameter. Distance between hind ocelli 0.78× maximum diameter of posterior ocellus. Hypostomal carina not lamelliform posteriorly to mandible. Face with deep and dense setiferous punctures, distance between them more than its diameter, setae long. Clypeal suture moderately curved. Clypeus 1.7× as broad as medially long, moderately convex with isolated fine punctures dorsally, flat and smooth ventrally, ventral margin slightly incurved. Malar space about 1.0× as long as basal mandibular width, with shallow and slightly granulate subocular sulcus. Antenna with 28 flagellomeres, first flagellomere about 6.0× as long as medially wide. Mesosoma (Figs 7A–B, 7D–E, 7H, 7J). Pronotum smooth and shiny with few setiferous punctures on posterior dorsal corner. Epomia as a very short carina at the bottom of the submarginal depression of pronotum. Mesoscutum shiny, with moderately dense and very shallow setiferous punctures, denser on anterior part of median lobe; anterior half of median lobe not conspicuously prominent, confluent with posterior half. Notaulus weak, reaching about 0.5 the length of mesoscutum. Mesopleuron shiny, with evenly sparse shallow setiferous punctures except at mid and dorsal posterior part. Epicnemial carina weak, its dorsal end straight, ending at level of centre of pronotum. Metapleuron, smooth and shiny, glabrous, about 2.5× as long as high. Submetapleural carina very weak, virtually extended on anterior 0.3 of metapleuron. Propodeum shiny with evenly sparse fine setiferous punctures, in dorsal view about 1.25× as long as medially wide. Propodeal spiracle about 0.13 the length to anterior end of pleural carina. Hind leg with femur about 3.5× as long as high, 1.0× as long as tibia. Fore wing with vein cu-a opposite to Rs & M; vein 2 rs-m about 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 1.67× as long as Cu 1 b. Hind wing with vein cu-a about 0.37 × as long as abscissa of Cu 1 between M and cu-a, vein cu-a slightly reclivous, first abscissa of Cu 1 vertical; distal abscissa of Cu 1 insinuated, unpigmented. Metasoma (Figs 7A, 7F–G, 7I). Tergite I about 1.5× as long as posteriorly broad, shiny, with moderately dense setiferous punctures laterally and posteriorly, spiracle near its anterior 0.35; lateromedian longitudinal carinae present at anterior 0.2 of tergite; lateral longitudinal carinae present at posterior 0.2 of tergite. Sternite I extending posteriorly about 0.6 the length of tergite. Tergite II about 1.15× as long as posteriorly broad, with dense deep punctures, distance between punctures less than its diameter; punctation of posterior tergites tending to be slightly shallower. Ovipositor evenly and slightly up-curved at 0.3 distal, 2.0× as long as hind tibia. Ovipositor sheath 1.7× as long as hind tibia, ventral margin basally without denticles, length of setae on average 2.3× the sheath basal width. Colouration (Fig. 7). Head mostly white cream, with apex of mandibles, fovea, narrow longitudinal stripe at middle of face, frons and vertex medially, middle and dorsal part of gena and occipital region, dark brown to black; antenna brown, scapus, pedicel, annellus and first to third flagellomere, ventrolaterally lighter. Mesosoma mostly light orange; propodeum dark brown to black; propleuron, dorsal lateral and ventral anterior band on pronotum, two longitudinal stripes on mesoscutum posteriorly to notauli, subalar prominence, scutellum, postscutellum, ventral part of mesopleuron, mesosternum, and lateral parts of propodeum, yellowish. Metasoma mostly dark brown; tergites I–VI with yellow posterolateral marks, tergites II–VI with dark brown to black posterior band; tergite I with yellowish anterior lateral marks; ovipositor brown; ovipositor sheaths black. Legs predominantly white cream; fore leg with dorsal stripes on femur and tibia, and distal part of tarsi, brown; mid leg with base of trochanter and tibia, dorsal and ventral stripes on femur and tibia, and distal part of tarsi, brown; hind leg with anterior and posterior spots on coxa, base of trochanter, base, and anterior and posterior subdistal marks on femur, basal and distal part of tibia, and distal part of tarsi, brown. Wings hyaline, pterostigma blackish brown. Male: Unknown. Etymology. The species name refers to the long and narrow metapleuron that characterizes this species. Type material (1 ♀). Holotype.
