( Figs 8 , 9 , 52A , Appendix I)

Diagnosis. Clistopyga arhuaca may be distinguished from other species of the C. calixtoi species group by the following combination of characters: genal orbits widely and entirely white cream ( Figs 8D , 9A ); predominantly black and white mesosoma and first metasomal tergite, with remain tergites mainly orange reddish to brownish ( Figs 8D–G , 9A, 9D, 9F ); lateral lobes of mesoscutum black with a white cream longitudinal lateral stripe ( Fig. 8D–F , 9A, 9F ); metapleuron 2.76–2.86× as long as high ( Figs 8D , 9A ); submetapleural carina absent ( Fig. 8D ); propodeum in dorsal view 1.55–1.65× as long as medially wide ( Fig. 8H ). Additionally, the male of C. arhuaca has very slightly impressed concavity posterior to mandibular base, the inner and outer margins of this concavity without long incurved setae ( Figs 9B , arrow, 9C).

Description. Female: Body length 9.4–12.8 mm. Fore wing length 6.9–9.2 mm.

Head ( Figs 8A, 8D, 8F ). In dorsal view, strongly narrowed behind eyes. Gena smooth and shiny with uniformly sparse setiferous punctures, in dorsal view slightly rounded, 0.30–0.32× as long as eye, in frontal view straight to slightly concave and moderately constricted below eyes. Frons and vertex smooth and shiny, with very isolated setiferous punctures. Posterior ocellus separated from eye 0.90–1.00× its maximum diameter. Distance between hind ocelli 0.64–0.71× maximum diameter of posterior ocellus. Hypostomal carina not lamelliform behind mandible. Face with fine and dense setiferous punctures, distance between punctures more than twice the diameter of punctures. Clypeal suture strongly curved. Clypeus 1.64–1.66× as broad as medially long, distinctly convex in dorsal half, flat in ventral half, with apical margin slightly concave. Malar space 0.73–0.75× as long as basal mandibular width, with a smooth narrow subocular sulcus. Antenna with 29–31 flagellomeres, first flagellomere 7.3–7.5× as long as wide.

Mesosoma ( Figs 8B–C, 8D, 8F, 8H ). Pronotum shiny, smooth, with fine and scattered setiferous punctures in dorsal posterior part. Epomia inconspicuous to absent. Mesoscutum entirely smooth and shiny, with fine setiferous punctures, denser on anterior part of 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 smooth and shiny, with very sparse small setiferous punctures on anterior and ventral part. 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, 2.76–2.86× as long as high. Submetapleural carina absent. Propodeum smooth and shiny, with evenly sparse fine setiferous punctures on anterior half of dorsal part and laterally, in dorsal view 1.55–1.65× as long as medially wide. Propodeal spiracle about 0.14 the length to anterior end of pleural carina. Hind leg with femur 3.86–4.03× as long as high, 1.09× as long as tibia. Fore wing with vein cu-a opposite to Rs & M; vein 2 rs-m 0.44–0.57× 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 1.39–1.57× as long as Cu 1 b. Hind wing with vein cu-a 0.42–0.50× as long as first abscissa of Cu 1 between M and cu-a, vein cu-a reclivous, first abscissa of Cu 1 vertical and straight; distal abscissa of Cu 1 weakly to well pigmented.

Metasoma ( Figs 8E, 8G, 8I ). Tergite I 1.73–1.79× as long as posteriorly broad, shiny, with sparse setiferous punctures laterally and posteriorly; spiracle near its anterior 0.4; lateromedian longitudinal carinae present at anterior 0.2 of tergite, very weak; lateral longitudinal carinae present at posterior 0.2 of tergite. Sternite I extending posteriorly about 0.5 of length of tergite. Tergite II 1.29–1.37× as long as posteriorly broad, with dense fine and relatively deep setiferous punctures, distance between punctures about its diameter; remaining tergites same microsculpture. Ovipositor relatively stout, strongly up-curved at distal 0.3, 2.1–2.3× as long as hind tibia. Ovipositor sheath 1.6– 1.8× as long as hind tibia, ventral margin basally without denticles, length of setae on average 2.0–2.3× the sheath basal width.

Colouration ( Fig. 8 ). Head mostly white cream with apex of mandibles, frons and vertex medially, posterior part of gena and occipital region black; antenna blackish brown, ventrally pallid proximally, with pedicel and scape ventrally white cream. Mesosoma white cream except the following black areas: pronotum anteriorly and medially on lateral surface, mesoscutum longitudinally on median and lateral lobes, and posteriorly, mark under subalar prominence, area around episternal scrobe, blotch on ventral hind corner of mesopleuron, margin of metapleuron, groove separating propodeum and metapleuron, and a broad stripe mediodorsally along propodeum. Metasoma with tergite I black with lateral and posterior margins marked with white; tergites II to VIII more or less entirely red to orange, tergite II black marked posterolaterally; ovipositor dark brown; ovipositor sheath black.

Hind wing with vein cu-a 0.39× as long as abscissa of Cu 1 between M and cu-a.

Metasoma ( Figs 9A, 9D, 9E ). Setae on tergites longer and denser than in females. Tergite I 1.96× as long as posteriorly broad. Tergite II 1.62× as long as posteriorly broad.

Colouration ( Fig. 9 ). As in female but with tergites III to V black marked posterolaterally.

Other features as in female.
