Diagnosis. Clistopyga horcoana may be distinguished from all other species of the C. calixtoi species group by the following combination of characters: genal orbit interrupted by dark brown or black ( Figs 18A, 18E View FIGURE 18 , 19A, 19C View FIGURE 19 ); mesosoma extensively red orange ( Figs 18C View FIGURE 18 , 19C–D View FIGURE 19 ); pronotum mostly blackish brown and white cream ( Figs 18C– D View FIGURE 18 , 19C View FIGURE 19 ); propodeum laterally broadly white cream ( Figs 18C View FIGURE 18 , 19C View FIGURE 19 ); hind femur yellow with subbasal and subdistal lateral brown marks ( Figs 18A View FIGURE 18 , 19A View FIGURE 19 ); metasoma mostly striking light orange with posterior white cream bands on tergites II–V(VI in male) ( Fig. 18F, 18H View FIGURE 18 , 19G–H View FIGURE 19 ); tergite I, without wide white cream band ( Figs 18F View FIGURE 18 , 19G View FIGURE 19 ); epomia strong and short, vertical ( Figs 18D View FIGURE 18 , arrow, 19C); fore wing with vein 2 rs-m 0.2–0.4× as long as abscissa of M between 2 rs-m and 2 m-cu ( Figs 18I View FIGURE 18 , 19E View FIGURE 19 ); metapleuron 2.0–2.4× as long as high ( Fig. 18G View FIGURE 18 ); propodeum in dorsal view 0.85–1.15× as long as medially wide ( Fig. 19D View FIGURE 19 ).
