Petralycini Uusitalo, 2010

Type genus: Petralycus Grandjean, 1943 .

Differential diagnosis. This tribe (and genus) can easily be segregated from the rest of the Endeostigmata by the strongly elongated but robust chelicerae; two pairs of prodorsal sensilla in separate bothridia, anterior pair ve being globular and posterior pair sci filamentous; palpal tarsi having a solenidion extending partly over a pair of distal mucronate eupathids; transform series of pedal solenidia from claviform and baculiform to uniquely thin, but not tapering (Figs. 135 A–D; Uusitalo 2010: figs. 147–149).
