Key to major and minor males of Gonyleptellus

1. Laterals of dorsal scutum covered along entire length with large/medium tiles ( Figure 1 (a)); femur IV arched or sinuous, armed with stout spiniform apophyses, especially retrolateral ( Figure 2 (a–d)... ................................................................................................................ 2 -Laterals of dorsal scutum with at most an outer fringe of small tiles; femur IV substraight, armed with feeble armature (spine length less than femur diameter).. ........ 3

2. Area II fully filled with tiles; proapical apophysis of coxa IV same length as trochanter IV.. ........................................................................... .......................................................................... G. angeloi Area II not fully filled with tiles ( Figure 1 (a)); proapical apophysis of coxa IV longer than trochanter IV ( Figure 2 (j–l)).. ............................................................................................................... 5

3. Carapace with a pair of bright oval flecks; retrolateral apophysis of coxa IV: vamp elongate falciform.. ....................................................................................................... G. cancellatus Carapace without oval flecks; retrolateral apophysis of coxa IV: vamp not as above... 4

4. Metatarsus IV unarmed; area V with 15 small tiles plus 2 medium-sized paramedian ones; retrolateral apophysis of coxa IV: heel square, vamp triangular.. ... G. pustulosus Metatarsus IV provided with a retrolateral row of teeth all along its extension; area V with 6 small tiles plus 2 medium sized paramedian ones; retrolateral apophysis of coxa IV: heel rounded subtriangular, vamp curved lanceolate.. ......................... G. bimaculatus

5. Dorso-basal spine of femur IV small; area III with a pair of paramedian rounded tubercles.. ................................................................................................................................................. G. pustulatus Dorso-basal spine of femur IV very stout ( Figure 2 (a,b,d)); area III with a pair of paramedian blunt spines ( Figure 1 (a,c) Figure 3 .).. ............................. G. camelopardalis sp. nov.
