Genus Pachyseiulus Moraza & Johnston, 1990

Pachyseiulus Moraza & Johnston, 1990: 213 .

Type species Pachyseiulus hispanicus Moraza & Johnston, 1990 (= Pachylaelaps singularis Schweizer, 1961), by original designation.

The monotypic genus Pachyseiulus was placed in the family Pachylaelapidae by Moraza & Johnston (1990), and their description needs no amendment. The genus is based mainly on the following character states: (1) dorsal shield with 37 pairs of setae, including a full complement of J, Z and S opisthonotal setae; (2) tarsus II in female with distal setae al1 and pl1 spur-like; (3) palp apotele 2-tined; (4) epistome nearly truncate, without anterior projection; (5) genitiventral shield bearing four pairs of setae; (6) male chelicera with fixed digit distally truncate. The type species of the genus, Pachyseiulus hispanicus, described from Northern Spain, was synonymised with Pachylaelaps singularis Schweizer, 1961 by Mašán (2007a), who examined Schweizer’s original type material.
