Key to the species of Litoblatta from Argentina based on males

1 Right paraproct with an extension “digital process” ( Fig. 36 ).......................................... L. argentina

- Right paraproct without such extension.................................................................... 2

2. Styli located at right angles; the right is transversal and the left is parallel to the body longitudinal axis ( Figs. 16–17 , 57–58 ). ................................................................................................... 3

- Styli parallel......................................................................................... 4

3. Both stylus with spines ( Fig. 17 )........................................................ L. misionerae sp. nov.

- Spines present only on the right stylus (short).......................................................... L. clara

4. Short conic spines on the internal basal margin of the right paraproct ( Figs. 22–23 )................ L. tucumanae sp. nov.

- Long spines on the internal basal margin of the right paraproct ( Figs 1–2 , 10 , 27, 30 )................................ 5

5. Spines distributed along the internal lateral margin of the paraproct ( Fig. 10 )......................... L. elisae sp. nov.

- Spines grouped on the internal lateral margin of the right paraproct.............................................. 6

6. Triangular right stylus ( Figs 4–5, 7 ). Right paraproct with a cone formed by a group of spines with adjacent bases and convergent apices ( Figs. 1–2 )......................................................................... L. lutea sp. nov.

- Right stylus with rounded apex. Right paraproct with a group of long spines, apically divergent ( Figs. 27, 30 )...................................................................................................... L. brasiliensis
