Diagnosis. In the adults, clunal setae J5 are vestigial, only microsetae present; 1–2 pairs of modified, hypertrophied and slot-like gland pores (gdS4, ±gdZ1) present on posterolateral dorsal margins (often gland pores gdS4 and gdZ1 closely adjacent); distal projection of epistome with short and wide neck. In the female, a tubular sperm access system is present; spermathecal tubes long to short, variably formed; movable digit of chelicera uni- to bidentate; pilus dentilis of fixed digit always minute, with normal position or directed anteriorly. In the male, the spermatodactyl is conspicuously elongated (more than 2 times as long as movable digit), long and slim, without medial widening (with parallel lateral margins), stiletto-like to blade-like, sharply tapered distally and without complex of ductules (sperm ductus narrow); axillar seta pv1 of femur II usually curved and always situated on tubercle connected with base of finger-like apophysis; 1–3 palptibial outgrowths present, outgrowths usually flat and small, never associated with seta.

Type species: Pachylaelaps (Olopachys) scutatus Berlese, 1910 .
