- At least genu II with setae.................................................... (Tydeinae and Triophtydeinae  )… 5

2 (1) Tibia I with solenidion and trochanter II with tactile setae, body reticulated........................................ 3

- Tibia I without solenidion and trochanter II without tactile setae, body with striae............. Prelorryia labrusca  sp. nov.

3 (2) Dorsal opisthosomal setae: c 1, d 1, e 1, f 1 and f 2 strongly barbed, longer or equal to half distance to the basis of next setae............................................................................. Pretydeus henriandrei Kaźmierski 

- Dorsal opisthosomal setae not so strongly barbed and much shorter.............................................. 4

4 (3) Dorsum incompletely reticulated except for median, evenly reticulated area of prodorsum, without raised areas......................................................................... Pretydeus curiosa (Ueckermann & Smith-Meyer) 

- Dorsum completely reticulated, with raised areas and regular lobes.......................... Pretydeus panitae ( Baker) 

5 (1) Tarsus I with 10 setae; at least four setae on femur I; genu II and III each with two setae...... Triophtydeus lebruni (André) 

- Tarsus I with eight setae; at most three setae on femur I; genu II and III never with two setae each........... (Tydeinae)… 6

6 (5) Femur IV nude; all dorsal setae similar in shape: flat, spatulate, but not expanded distally..... Afrotydeus kenyensis ( Baker) 

- Femur IV with one seta, dorsal setae variously shaped........................................................ 7

7 (6) Femur III with two setae and trochanter II and IV each with one seta.............................. ( Brachytydeus  )… 8

- Femur III with one seta or trochanter II and IV nude or with setae ( Neolorryia  and Tydeus  ).......................... 10

8 (7) Dorsal setae ro, la, ex serrated and remaining setae on dorsal spatulated, seta p' ζ not T-shaped distally............................................................................................. Brachytydeus podocarpa ( Baker)
