Diagnosis. Clistopyga kogabae may be distinguished from all other species of the C. calixtoi species group by the following combination of characters: genal orbits widely interrupted with dark brown or black ( Figs 26E , 27A ); mesoscutum orange ( Figs 26G , 27C ); pronotum predominantly black and orange, dorsally and ventrally with white cream bands ( Figs 26C–E , 27D ); mesopleuron entirely orange ( Figs 26A, 26E , 27A ); propodeum with lateral white cream or yellow marks (26A, 26E, 27A); metapleuron tricoloured, gradually from black ventrally, orange and white cream dorsally ( Fig. 26A, 26E , 27A ); metasoma dark brown to black without posterior defined white or yellow wide marks on tergites ( Figs 26A, 26F, 26H , 27A, 27E, 27G ); submetapleural carina weak, extended at most on anterior 0.4 of metapleuron ( Fig. 26E ). Additionally, female has epomia as a very short inconspicuous carina or tubercle at the bottom of the submarginal depression of pronotum Fig. 26C–D ), sometimes virtually absent; ovipositor relatively slender, evenly up-curved at distal 0.3, 2.0–2.3× as long as hind tibia ( Figs 26A, 26F, 26J ); ovipositor sheath 1.75–1.9× as long as hind tibia; ventral margin of ovipositor sheath basally without small denticles. Male has gena, in frontal view, straight or slightly convex in profile, without any traces or longitudinal concavity posterior to mandible base ( Fig. 27B ); epomia absent ( Fig. 27D ); tergite II almost smooth, with relatively sparse and shallow, setae relatively short ( Fig. 27E ).

Other characters as in female.

Etymology. The specific name refers to “kogaba”, one of the languages spoken by the Arhuacos tribe on The Sierra Nevada de Santa Marta, to which the Tayrona National Park belongs and where the holotype was collected.
