Key to subfamilies and tribes of Alycidae

1. Cuticular pattern comprising striae with many small lamellae ( Figs. 3 View FIGURES 1−5 , 29 View FIGURES 29−35 , 48 View FIGURES 48−53 , 63 View FIGURES 63−67 , 76 View FIGURES 76−83 , 134 View FIGURE 134 C–F); chelicerae chelate, with 2−6 teeth each, and with or without seta ( Figs. 18 View FIGURES 16−22 , 34 View FIGURES 29−35 , 135 View FIGURE 135 D–F; Theron 1977: fig. 8); rutella well developed ( Figs. 6 View FIGURES 6−13 , 20 View FIGURES 16−22 , 36 View FIGURES 36−42 , 52 View FIGURES 48−53 , 70 View FIGURES 68−75 ; Theron 1977: fig. 10; Uusitalo 2010: fig. 29); area from naso to anterior sensilla (=crista) more or less sclerotized ( Figs. 1 View FIGURES 1−5 , 16 View FIGURES 16−22 , 29 View FIGURES 29−35 , 48 View FIGURES 48−53 , 63 View FIGURES 63−67 , 76 View FIGURES 76−83 , 135A, B View FIGURE 135 ). ( Alycinae )...................................................................... 2

- Cuticular patterning more complex, often reticulate or rosetted primary pattern, with many large lamellae or formed only by large lamellae ( Figs. 92 View FIGURES 90−100 , 105 View FIGURES 105−111 , 119 View FIGURES 119−125 , 133 View FIGURE 133 A–F, 134A, B); chelicerae stylet-like ( Figs. 94 View FIGURES 90−100 , 108 View FIGURES 105−111 ; Uusitalo 2010: fig. 123); rutella absent ( Figs. 95 View FIGURES 90−100 , 109 View FIGURES 105−111 , 123 View FIGURES 119−125 ; Uusitalo 2010: fig. 92); crista sclerotized or smooth ( Figs. 90 View FIGURES 90−100 , 105 View FIGURES 105−111 , 119 View FIGURES 119−125 ; Uusitalo 2010: figs. 90, 100, 110, 120, 130); posterior pair of sensilla globular ( Fig. 106 View FIGURES 105−111 ); empodia clawless ( Figs. 100 View FIGURES 90−100 , 113 View FIGURES 112−116 , 127 View FIGURES 126−130 ). ( Bimichaeliinae )..... 3

2. Both pairs of prodorsal sensilla are either filamentous ( Fig. 1 View FIGURES 1−5 ) or slightly swollen ( Fig. 27 View FIGURES 23−28 ); chelicerae with 1−2 strong teeth on each fixed digit ( Figs. 34 View FIGURES 29−35 , 135E, F View FIGURE 135 ; Uusitalo 2010: fig. 63); usually with a pair of rudimentary posterolateral eyes ( Figs. 1 View FIGURES 1−5 , 16 View FIGURES 16−22 , 63 View FIGURES 63−67 ; Uusitalo 2010: figs. 12, 75, 82); empodia with an apical hook ( Figs. 13 View FIGURES 6−13 , 22 View FIGURES 16−22 , 37 View FIGURES 36−42 , 57 View FIGURES 54−59 , 73 View FIGURES 68−75 , 83 View FIGURES 76−83 )................... Alycini

- Anterior pair of sensilla globular ( Figs. 135A, B View FIGURE 135 ); chelicerae with 3−6 teeth similar in size on each fixed digit ( Fig. 135D View FIGURE 135 ; Theron 1977: fig. 8; Uusitalo 2010: fig. 143); eyes absent ( Figs. 135A, B View FIGURE 135 ; Theron 1977: figs. 2, 16); empodia clawless ( Fig. 135D View FIGURE 135 ; Theron 1977: figs. 11, 27)................................................................. Petralycini

3. Large lamellae in rosettes and in clumps, secondary pattern absent i.e. ridges glabrous ( Figs. 92 View FIGURES 90−100 , 134A, B View FIGURE 134 ; Uusitalo 2010: Appendix 3) cheliceral seta present ( Fig. 94 View FIGURES 90−100 ); prodorsum with a pair of eyes ( Fig. 104 View FIGURES 101−104 )........... Proteromichaeliini trib. nov.

- Large lamellae in rosettes or in clumps, secondary pattern granular or by small lamellae ( Figs. 105 View FIGURES 105−111 , 119 View FIGURES 119−125 , 133 View FIGURE 133 A–F); cheliceral seta absent ( Figs. 108 View FIGURES 105−111 , 120 View FIGURES 119−125 ; Uusitalo 2010: fig. 102); prodorsum without eyes ( Fig. 105 View FIGURES 105−111 )...................
