Key to species of Boethella

1. Malar space 0.5× basal width of mandible ( Fig. 9 )................................................... B. darlingi

- Malar space obliterated, mandible margin contiguous with ventral edge of eye ( Figs 4 , 12 , 15 )........................ 2

2. Auxiliary carina of mesopleuron extending from anterior edge and joining epicnemial carina ( Fig. 7 )................... 3

- Auxiliary carina of mesopleuron not extending to epicnemial carina ( Figs 1 , 4 , 18 )................................. 4

3. Epicnemial carina extending dorsal to point of union of auxiliary carina by at least the length of auxiliary carina ( Fig. 7 ); T4 predominantly brown, yellow laterally and sometimes with a yellow median longitudinal stripe or spot ( Fig. 6 ).... B. curriei

- Epicnemial carina extending dorsal to point of union of auxiliary carina by much less than the length of auxiliary carina ( Fig. 12 ), or not extending at all; T4 entirely yellow or yellow with a trace of brown in apical 0.2 and with a longitudinal brown or brown and white region in median apical 0.3 ( Fig. 10 )............................................... B. guidottiae

4. Auxiliary carina of mesopleuron curving sharply at midpoint so it runs parallel to anterior edge of mesopleuron ( Fig. 18 ); hind femur black ( Fig. 16 )...................................................................... B. jatai sp. nov.

- Auxiliary carina of mesopleuron not curving sharply at midpoint; hind femur yellow or orange........................ 5

5. Hind tibia dark brown, except light brown at base ( Fig. 2 ).............................................. B. canilae

- Hind tibia basal 0.7 yellow, apical 0.3 brown ( Fig. 14 )................................................. B. hubleyi
