Clistopyga splendida Palacio & Bordera  sp. nov.

( Figs 7A–J View Figure , 9E View Figure , 11A, D, F View Figure )

Diagnosis. Clistopyga splendida  sp. nov. can be distinguished from all other species of the C. isayae  species group by the combination of the following characters: subalar prominence densely punctate, at least with 24 setiferous punctures ( Fig. 11A View Figure ); occipital carina present dorsally as a pair of mediodorsal wrinkles and ventrally as a short vestige ( Fig. 11D View Figure ); distance between hind ocelli 0.74–0.75 × maximum diameter of posterior ocellus; fore wing with vein 2 rs-m about 0.44–0.50 × as long as abscissa of M between 2 rs-m and 2 m-cu ( Fig. 7G View Figure ); hind wing with abscissa of Cu 1 between 1 m-cu and Cu 1 a 1.75 × as long as Cu 1 b ( Fig. 7H View Figure ).

Description. Female: Body length 11.8–14.4 mm. Fore wing length 8.4–10.1 mm.

Head ( Figs 7A–C View Figure , 11D View Figure ). In dorsal view, moderately narrowed behind eyes. Gena smooth and shiny with uniformly sparse setiferous punctures, in dorsal view 0.27–0.29 × as long as eye (7C), in frontal view almost straight and moderately constricted below eyes. Frons smooth and shiny. Vertex smooth and shiny, with very isolated setiferous punctures. Posterior ocellus separated from eye 0.91–1.12 × its maximum diameter ( Fig. 7C View Figure ). Distance between hind ocelli 0.74–0.75 × maximum diameter of posterior ocellus. Occipital carina present dorsally as a pair of mediodorsal wrinkles and ventrally as a short vestige ( Fig. 11D View Figure ). Face with fine and dense setiferous punctures, distance between punctures more than twice the diameter of punctures. Clypeal suture slightly curved ( Fig. 7B View Figure ). Clypeus 1.85–1.91 × as broad as medially long, distinctly convex in dorsal half, flat in ventral half, with apical margin bilobate. Malar space 0.69–0.73 × as long as basal mandibular width, with a granulate stripe beetween eye and mandible ( Fig. 7A, B View Figure ). Antenna with 26–27 flagellomeres, first flagellomere 6.7–7.2 × as long as wide.

Mesosoma  ( Figs 7D, 7I View Figure , 11A View Figure ). Pronotum shiny, mostly smooth, with fine and scattered setiferous punctures in upper posterior part. Mesoscutum entirely smooth and shiny, with fine and sparse setiferous punctures. Notauli deep, reaching about 0.42 of length of mesoscutum ( Fig. 7I View Figure ). Mesopleuron shiny, with moderately sparse setiferous punctures, except in posterior part under speculum. Subalar prominence densely punctate, with about 24–42 setiferous punctures ( Fig. 11A View Figure ). Epicnemial carina weak, its dorsal end straight, ending at level of centre of pronotum. Metapleuron shiny, glabrous, except for some sparse setiferous punctures at posterior end, 2.7–2.9 × as long as deep. Propodeum smooth and shiny, with sparse and fine setiferous punctures laterally; in dorsal view 1.2– 1.3 × as long as medially wide. Propodeal spiracle contiguous with groove separating propodeum and metapleuron, groove not interrupted by spiracle ( Fig. 7D View Figure ). Hind leg with femur 4.16–4.26 × as long as deep, 0.90–1.01 × as long as tibia.

Wings ( Figs 7G–H View Figure ). Fore wing with vein cu-a opposite Rs & M. Vein 2rs-m about 0.44–0.50 × as long as abscissa of M between 2rs-m and 2 m-cu. Abscissa of Cu 1 between 1 m-cu and Cu 1 a 1.75 × as long as Cu 1 b ( Fig. 7G View Figure ). Hind wing with vein cu-a about 0.27 × as long as abscissa of Cu 1 between M and cu-a (7H). Vein cu-a reclivous, abscissa of Cu 1 vertical and slightly curved. Vein Cu 1 well pigmented.

Metasoma ( Figs 7E–F, 7J View Figure , 9E View Figure ). Tergite I 1.5–1.6 × as long as posteriorly broad ( Fig. 9E View Figure ), smooth and shiny, with fine and relatively dense setiferous punctures laterally; spiracle near its basal 0.4; lateromedian longitudinal carinae strong, reaching about 0.2 of length of tergite; lateral longitudinal carinae weak, reaching about 0.35 of length of tergite. Sternite 1 extending back about 0.5 of length of tergite. Tergite II 1.28–1.39 × as long as posteriorly broad ( Fig. 7J View Figure ), central region shiny, with very fine and moderately sparse setiferous punctures; rest of tergites shiny, progressively more densely and strongly punctate. Ovipositor relatively stout, shiny, very weakly upcurved at distal 0.2, 3.0–3.3 × as long as hind tibia ( Fig. 7F View Figure ). Ovipositor sheath about 2.4 × as long as hind tibia, length of setae on average about 1.5 × the sheath basal width.

Colouration. Head white with vertex, occipital region, frons centrally and under antennal sockets, clypeal suture and tentorial pits black; antenna blackish brown, ventrally pallid at base, with pedicel and scape ventrally white ( Figs 7A–C View Figure ). Mesosoma  with most of mesoscutum, scutellum centrally, most of pronotum and mesopleuron, and anterior and upper half of metapleuron red; median lobe of mesoscutum laterally, scutellum laterally, metanotum; tegula, anterior margin of pronotum, subalar prominence, a stripe on lower half of mesopleuron, mesepimeron, and lower posterior half of metapleuron white; propleura white, blackish at base; ventral margin of metapleuron and groove between propodeum and metapleuron black; propodeum white with a broad black mediodorsal stripe ( Figs 7D, I View Figure ). Metasoma with tergite I black with lateral and posterior margins white marked ( Fig. 9E View Figure ); tergites from II to the last blackish brown; tergites II–V white marked posterolaterally, although with extreme margins black ( Figs 7E, J View Figure ); ovipositor sheath black. Fore and mid of legs predominantly white, coxae laterally and proximally black, trochanters proximally black, femora and tibia dorsally striped with black and tarsi infuscate; hind leg white with coxa laterally and proximally, trochanter proximally, femur laterally and proximally, and tibia proximally, laterally and distally black; hind tarsal segments predominantly blackish. Wings weakly infumate, pterostigma blackish brown.

Male: unknown.

Etymology. The specific name refers to the beautiful colour patterns of this species.
