Key to species of the Orasema festiva   group

Males are unknown for O. alvarengai   , O. festiva   , and O. reburra   , but based on the other species features appear to be valid for both sexes.

1. Eye with long setae ( Fig. 7 View FIGURES 7 – 10 )......................................................... Orasema caesariata   n. sp.

- Eye without visible setae at 50 × magnification ( Figs 3 View FIGURES 2 – 6 , 11 View FIGURES 11 – 16 , 18 View FIGURES 18 – 21 , 22 View FIGURES 22 – 25 , 27 View FIGURES 26 – 29 )............................................ 2

2. Coxae dark brown ( Figs 26, 29 View FIGURES 26 – 29 ). Petiole with many (> 10) long setae ( Fig. 29 View FIGURES 26 – 29 ).................... Orasema reburra   n. sp.

- Coxae yellow ( Figs 2, 5 View FIGURES 2 – 6 , 12 View FIGURES 11 – 16 , 21 View FIGURES 18 – 21 , 24 View FIGURES 22 – 25 ). Petiole bare ( Figs 5 View FIGURES 2 – 6 , 14 View FIGURES 11 – 16 , 21 View FIGURES 18 – 21 , 24 View FIGURES 22 – 25 ), or with few (<5) very tiny decumbent setae are not easily visible at 50 x magnification ( Fig. 5 View FIGURES 2 – 6 )....................................................................... 3

3. Petiole parallel-sided in dorsal view, smooth and without a dorsal longitudinal carina ( Fig. 24 View FIGURES 22 – 25 ).... Orasema festiva (Fabricius)  

- Petiole laterally expanded near midlength, with some dorsal sculpture and/or dorsal longitudinal carina ( Figs 5 View FIGURES 2 – 6 , 14 View FIGURES 11 – 16 , 21 View FIGURES 18 – 21 )..... 4

4. Petiole only slightly laterally expanded near midlength: at least 3.5 × as long as broad in both sexes ( Fig. 21 View FIGURES 18 – 21 )................................................................................................. Orasema erwini   n. sp.

- Petiole more strongly laterally expanded near midlength: not more than 2.8 × as long as broad in females ( Figs 5 View FIGURES 2 – 6 , 14 View FIGURES 11 – 16 ), 3.27 × as long as broad in males.................................................................................. 5
