Genus Pachysphaerolaelaps Mašán, 2007

Pachysphaerolaelaps Mašán, 2007a: 198.

Type species Laelaps calcariger Berlese, 1902, by original designation.

The diagnosis of the monotypic genus Pachysphaerolaelaps was based on the following character states: (1) dorsal shield and soft integument hypertrichous; (2) almost all leg segments with an increased number of setae; (3) epistome unipartite and elongate; (4) male femur II with two adjacent cuticular processes; (5) idiosoma subglobular; (6) legs longer than dorsal shield; (7) gland opening gdS4 hypertrophied and circular; (8) anal shield subcircular; and (9) tarsus II uniformly setaceous and without spur-like distal setae. Pachysphaerolaelaps was proposed to accommodate the species Laelaps calcariger Berlese, 1902, which was a member of the genus Sphaerolaelaps as classified by Berlese (1904) and subsequent authors (Koroleva, 1977b; Karg, 1993).
