Key to subfamilies and tribes of Alycidae

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

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

2. Both pairs of prodorsal sensilla are either filamentous (Fig. 1) or slightly swollen (Fig. 27); chelicerae with 1−2 strong teeth on each fixed digit (Figs. 34, 135E, F; Uusitalo 2010: fig. 63); usually with a pair of rudimentary posterolateral eyes (Figs. 1, 16, 63; Uusitalo 2010: figs. 12, 75, 82); empodia with an apical hook (Figs. 13, 22, 37, 57, 73, 83)................... Alycini

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

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

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