Key to Chilean Species of Doeringiella

1. Mesosoma with setation entirely black except on dorsum of pronotum and anterior transverse band on mesoscutum ( Fig. 7 ); metasoma with pale apical bands primarily on T1 and T2 ( Figs. 7, 9 ); far northern Chile (Region XV) ..................................................................... D. mamabee Packer , n. sp.

—. Mesosoma with abundant pale setation ( Fig. 12 ); metasoma with pale markings distinct on all terga ( Fig. 12 ); central and southern Chile (from Region IV south to Region X) ..................................................................................................... 2

2(1). Male scape not swollen ( Fig. 13 ); male S5 with complete row of approximately equally long hairs ( Fig. 14 ); female T5 with pseudopygidial area at least as long as wide ( Fig. 15 ) ........................................... D. gayi (Spinola)

—. Male scape considerably swollen ( Fig. 16 ); male S5 with moderately long hairs laterally, short medially ( Fig. 17 ); female T5 with pseudopygidial area much shorter than broad ( Fig. 18 ) .............................................. D. gigas (Spinola) Note, although females of the new species are unknown, the characters used in the key above are not generally sexually dimorphic among these bees and both sexes should be identifiable using it.

Figures

Figures 7–11. Doeringiella mamabee, new species, holotype male. 7. Lateral habitus. 8. Base of antenna to show swollen scape. 9. Dorsal view of mesosoma to show mostly black hairs. 10. Ventral view of propodeum to show supraspiracular carina, the round structure immediately above the spiracle. 11. Genital capsule. Scale bars = 1 mm.

Figures 12–18. Key characters permitting identification of Chilean species of Doeringiella Holmberg [12–15, Doeringiella gayi (Spinola); 16–18, D. gigas (Spinola)]. 12. Oblique dorsal view to show abundant pale pubescence on male meso- and metasoma. 13. Base of male antenna to show lack of swelling of scape. 14. Apex of male metasoma in ventral view to show approximately even length of apical hair row on S5. 15. Apex of female metasoma in dorsal view to show elongate pseudopygidial area. 16. Base of male antenna to show swollen scape. 17. Apex of male metasoma, ventral view, to show shorter hairs medially on apical fringe of S5. 18. Apex of female metasoma, dorsal view, to show short pseudopygidial area. Scale bars = 1 mm.
