Taxonomy of the atrata View in CoL species-group atrata species-group
Diagnosis. The atrata species-group is here defined to include those members of the genus Belonogaster in which the posterior face of the propodeum is entirely finely shagreened and bare, with at most some punctures and setae on the margins ( Figs 1F View FIGURE 1 , 2H View FIGURE 2 , 3E View FIGURE 3 , 4H View FIGURE 4 ).
Key to the species of the atrata View in CoL species-group
(The key is mostly based on the females, as the males of Belonogaster atrata and B. levior are currently unknown)
1. Dorsal side of mesosoma with erect black setae of variable length and with short but clearly hair-like pubescence. Integuments of mesosoma, except posterior face of propodeum, with very fine shagreen and silky shiny, bearing distinct and deep sparse punctures........................................................................................... 2
– Dorsal side of mesosoma without black setae, densely covered in dust-like pubescence. Integuments of mesosoma, except posterior face of propodeum, with coarser micropunctures or shagreen, matte, bearing only few scattered indistinct punctures ................................................................................................... 3
2. Mesosoma with bright golden-brassy pubescence, more evident on pronotum and mesoscutum ( Figs 2A–B View FIGURE 2 ). T 1 longer and slenderer, much longer than mesosoma, subapical expansion barely wider than basal width in dorsal view ( Fig. 2A View FIGURE 2 ); basal petiole of T 2 longer, length:width 2.4 in male ( Fig. 2F View FIGURE 2 ) and 2.8 in female ( Fig. 2G View FIGURE 2 ). Mesosoma and legs extensively marked with ferruginous-red, wings subhyaline with reddish tinge and slightly darker apex.................. B. aurata Richards
– Mesosoma with pale whitish-yellow pubescence ( Figs 1B–C View FIGURE 1 ). T 1 shorter and more robust, about as long as mesosoma, subapical expansion much wider than basal width in dorsal view ( Fig. 1B View FIGURE 1 ); basal petiole of T 2 shorter, length:width 1.5 in female ( Fig. 1E View FIGURE 1 ; male unknown). Mesosoma and legs entirely black or at most scutellum and metanotum red, wings blackish with distinct blue-purple reflections.............................................................. B. atrata von Schulthess
3. Disc of scutellum narrower, 1.55× as wide as long; median longitudinal furrow deep and well-impressed, dividing the disc of scutellum into two gibbosities ( Fig. 3E View FIGURE 3 ). Scutellum and metanotum shagreened like propodeum, bearing small but deep and well defined punctures ( Fig. 3E View FIGURE 3 ). Basal pit of propodeum shallow and wide, weakly indicated ( Fig. 3E View FIGURE 3 ). Basal petiole of T 2 shorter, length:width 1.6 in female ( Fig. 3D View FIGURE 3 ; male unknown). Mesosoma black, with reduced dark-red markings............................................................................................... B. levior Richards
– Disc of scutellum wider, 1.8× as wide as long; median longitudinal furrow shallow and barely impressed, not clearly dividing the disc of scutellum into two parts ( Fig. 4H View FIGURE 4 ). Scutellum and metanotum densely micropunctate, bearing very fine and barely noticeable punctures ( Fig. 4H View FIGURE 4 ). Basal pit of propodeum deep and narrow, well defined ( Fig. 4H View FIGURE 4 ). Basal petiole of T 2 longer, length:width 1.6 in male ( Fig. 4F View FIGURE 4 ) and 1.8 in female ( Fig. 4G View FIGURE 4 ). Mesosoma ferruginous, irregular dark markings on mesoscutum and pronotum only....................................................... B. velutina Selis & Longair , sp. nov.
