Key to the species of Bicoxidens

1. Apical region of telocoxite with a flattened median process that overlaps the opposite one; median leaf with an apical median axe-shaped process; telopodite with a long femoral lobe (Figs. 2 a, 5a)...................2

- Apical region of telocoxite without a flattened median process; median leaf without apical axe-shaped process; telopodite with a short femoral lobe (Figs 1 a, 3a, 4a, 6a, 7a, 8a)...................................................3

2. Apical telocoxite with a horizontal lateral process; apically lateral leaf with a small, transverse, ear-shaped aboral projection (Fig. 5b) ................................................................................................................ grandis

5. Apical telocoxite with two broadly rounded median processes that may be in touch................................6

- Apical telocoxite with three narrowly rounded or overlapping median processes.......................................7

6. Apical telocoxite with an overhanging folded lateral process above and not extending beyond knee bend; median processes do not touch; median leaf constricted subapically but without a basal lateral lobe (Figs. 4 a, 4b) ................................................................................................................................ gokwensis sp. n.

- Apical telocoxite with a broadly rounded lateral process above and extending beyond knee bend; median processes reciprocally in touch, leaving a window between them; sub-apically (below setose area), median leaf constricted and with a basal lateral lobe (Fig. 6 a) ........................................ matopoensis sp. n

7. Apical telocoxite bird head-shaped with three median processes, the middle long, beak-like and overlapping the opposite one (Figs. 1 a, 1b)................................................................................................... brincki
