Chaetodellus Mašán & Halliday, 2013 .

Type species Chaetodellus comatus Mašán & Halliday, 2013, by original designation.

We described the new genus Chaetodellus to accommodate two species that have some character states that are not consistent with Pachylaelaps, namely (1) vertical setae j1 reduced and minute; (2) genitiventral shield with three instead of two pairs of ventral setae; (3) tarsus II without setae modified into a spur; (4) sperm access system associated with coxae III; (5) genu I with 12 (2-5/3-2) instead of 11 or 13 setae (2-5/2-2 or 2-6/3-2); (6) dorsal setae heterogeneous in length, some with unusual positions on the dorsal shield, for example setae J1 antiaxial to J2; (7) strong reduction in the number of R setae inserted in the lateral soft integument.
