Key to subfamilies and tribes of Alycidae 

1. Cuticular pattern comprising striae with many small lamellae ( Figs. 3View FIGURES 1−5, 29View FIGURES 29−35, 48View FIGURES 48−53, 63View FIGURES 63−67, 76View FIGURES 76−83, 134View FIGURE 134 C–F); chelicerae chelate, with 2−6 teeth each, and with or without seta ( Figs. 18View FIGURES 16−22, 34View FIGURES 29−35, 135View FIGURE 135 D–F; Theron 1977: fig. 8); rutella well developed ( Figs. 6View FIGURES 6−13, 20View FIGURES 16−22, 36View FIGURES 36−42, 52View FIGURES 48−53, 70View FIGURES 68−75; Theron 1977: fig. 10; Uusitalo 2010: fig. 29); area from naso to anterior sensilla (=crista) more or less sclerotized ( Figs. 1View FIGURES 1−5, 16View FIGURES 16−22, 29View FIGURES 29−35, 48View FIGURES 48−53, 63View FIGURES 63−67, 76View FIGURES 76−83, 135A, BView 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. 92View FIGURES 90−100, 105View FIGURES 105−111, 119View FIGURES 119−125, 133View FIGURE 133 A–F, 134A, B); chelicerae stylet-like ( Figs. 94View FIGURES 90−100, 108View FIGURES 105−111; Uusitalo 2010: fig. 123); rutella absent ( Figs. 95View FIGURES 90−100, 109View FIGURES 105−111, 123View FIGURES 119−125; Uusitalo 2010: fig. 92); crista sclerotized or smooth ( Figs. 90View FIGURES 90−100, 105View FIGURES 105−111, 119View FIGURES 119−125; Uusitalo 2010: figs. 90, 100, 110, 120, 130); posterior pair of sensilla globular ( Fig. 106View FIGURES 105−111); empodia clawless ( Figs. 100View FIGURES 90−100, 113View FIGURES 112−116, 127View FIGURES 126−130). ( Bimichaeliinae  )..... 3

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

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

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

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