Key to males of Nanophareus species

1. Scutal area IV undivided and prolateral apical apophysis of coxa IV bifid ( Fig. 2 A, C).............................. 2

- Scutal area IV divided by a longitudinal median groove and prolateral apical apophysis of coxa IV single branched ( Fig. 6 A, C)................................................................................ N. bipartitus sp. nov.

2.(1) Prolateral apical apophysis of coxa IV apically bifid with two very short branches ( Figs. 2 C, 4C)..................... 3

- Prolateral apical apophysis of coxa IV bifid from subasal region, directed backwards, dorsal branch longer than ventral one ( Fig. 8 A, C)..................................................................... N. bosqenublado sp. nov.

3.(2) Ocularium low and widened (apparent aspect of a divided ocularium), frontal hump and scutal area III unarmed ( Fig. 2 A, C)............................................................................................. N. palpalis

- Ocularium domed and with normal width (approximately ½ of carapace width), frontal hump with two median, enlarged, high tubercles and scutal area III with a pair of paramedian low spines ( Fig. 4 A, C, G)................. N. araucanus sp. nov.
