Clistopyga panchei Palacio  sp. nov.

( Figs 6A–J View Figure , 9D View Figure , 11C View Figure )

Diagnosis. Clistopyga panchei  sp. nov. can be distinguished from all other species of the C. isayae  species group by the combination of the following characters: mesoscutum with moderately long and sparse setiferous punctures ( Fig. 6D View Figure ); antenna with 24 flagellomeres; occipital carina completely absent; subalar prominence sparsely punctate, with about 18 setiferous punctures ( Fig. 11C View Figure ); epicnemial carina ending slightly below level of centre of pronotum; hind wing with vein cu-a about 0.29 × as long as abscissa of Cu 1 between M and cu-a ( Fig. 6H View Figure ); setae of ovipositor sheath with a length on average about 1.85 × the sheath basal width.

Description. Female: Body length 8.3 mm. Fore wing length 5.6 mm.

Head ( Figs 6A–C View Figure ). In dorsal view, moderately narrowed behind eyes. Gena smooth and shiny with uniformly sparse setiferous punctures, in dorsal view 0.26 × as long as eye ( Fig. 6C View Figure ), 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 1.08 × its maximum diameter ( Fig. 6C View Figure ). Distance between hind ocelli 0.92 × maximum diameter of posterior ocellus. Occipital carina completely absent. Face with fine and dense setiferous punctures, distance between punctures more than twice the diameter of punctures. Clypeal suture strongly curved ( Fig. 6B View Figure ). Clypeus 1.80 × as broad as medially long, distinctly convex in dorsal half, flat in ventral half, with apical margin bilobate. Malar space 0.76 × as long as basal mandibular width, with a granulate stripe between eye and mandible ( Figs 6A, B View Figure ). Antenna with 24 flagellomeres, first flagellomere 6.5 × as long as wide.

Mesosoma  ( Figs 6D, 6I View Figure , 11C View Figure ). Pronotum shiny, mostly smooth, with fine and scattered setiferous punctures in upper posterior part. Mesoscutum entirely smooth and shiny, with moderately long and sparse setiferous punctures. Notauli moderately deep, reaching about 0.38 of length of mesoscutum ( Fig. 6I View Figure ). Mesopleuron shiny, with moderately sparse setiferous punctures, except in posterior part under speculum. Subalar prominence sparsely punctate, with about 18 setiferous punctures ( Fig. 11C View Figure ). Epicnemial carina weak, its dorsal end straight, ending slightly below level of centre of pronotum. Metapleuron shiny, glabrous, except for some sparse setiferous punctures at posterior end, 2.5 × as long as deep. Propodeum smooth and shiny, with sparse and fine setiferous punctures laterally; in dorsal view 1.3 × as long as medially wide. Propodeal spiracle contiguous with groove separating propodeum and metapleuron, groove barely interrupted by spiracle ( Fig. 6D View Figure ). Hind leg with femur about 3.4 × as long as deep, about 0.95 × as long as tibia.

Wings ( Figs 6 G–H View Figure ). Fore wing with vein cu-a opposite Rs & M. Vein 2 rs-m about 0.38 × 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 1.44 × as long as Cu 1 b ( Fig. 6G View Figure ). Hind wing with vein cu-a about 0.29 × as long as abscissa of Cu 1 between M and cu-a ( Fig. 6H View Figure ). Vein cu-a reclivous, abscissa of Cu 1 vertical and straight. Vein Cu 1 well pigmented.

Metasoma ( Figs 6E–F, 6J View Figure , 9D View Figure ). Tergite I 1.7 × as long as posteriorly broad ( Fig. 9D 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 basally strong, reaching about 0.35 of length of tergite. Sternite I extending back about 0.4 of length of tergite. Tergite II 1.50 × as long as posteriorly broad ( Fig. 6J View Figure ), central region shiny, with very fine and moderately sparse setiferous punctures; rest of tergites shiny, progressively more densely and strongly punctate. Ovipositor slender, shiny, very weakly upcurved at distal 0.2, 3.2 × as long as hind tibia ( Fig. 6F View Figure ). Ovipositor sheath about 2.4 × as long as hind tibia, length of setae on average about 1.85 × the sheath basal width.

Colouration. Head black with clypeus, frontal orbits widely, lower gena, and mouthparts, except apex of mandibles, white; antenna blackish brown, ventrally pallid proximally, and with pedicel and scape ventrally white ( Figs 6A–C View Figure ). Mesosoma  with most of mesoscutum and upper half of mesopleuron red; medial lobe of mesoscutum laterally, scutellum laterally, metanotum, tegula, subalar prominence, lower half of mesopleuron and mesepimeron white; propleuron white; pronotum red with anterior and upper margins white; propodeum white with a broad black mediodorsal stripe ( Figs 6D, I View Figure ). Metasoma with tergites blackish brown; tergite I with lateral and posterior margins marked with white ( Fig. 9D View Figure ); tergites II–VI white marked posterolaterally, although with extreme posterolateral margins black ( Fig. 6E, J View Figure ); ovipositor sheath black. Anterior two pair of legs predominantly white, fore trochanter proximally black, fore and middle femora and tibia dorsally striped with black and tarsi infuscate; hind leg white with coxa laterally, trochanter proximally, femur laterally and proximally, and tibia proximally, laterally and distally black; hind tarsal segments predominantly blackish. Wings hyaline, pterostigma blackish brown.

Male: unknown.

Etymology. This species is named in honor of the Precolombine indigenous tribe of Panches, who lived in the territory that today is the type locality, Cundinamarca ( Colombia).
