There is a depression at the posterior part of opisthogastric area (below anus) with ornamented decoration ( Fig. 1 ). There are additional Zx setae between Z1 and Z2 on dorsal idiosoma ( Fig. 2a ). Peritreme is wider at the beginning compared to its anterior part in Leitneria ( Fig. 2c ), whereas in the genus Halolaelaps there are large and triangular plates on posterolateral of sternal shield, lacking extra Zx setae and peritreme becomes wider at anterior part.
