3.1.1. Miridex gen. nov.

The genus Miridex displays all features of the Demodecidae , indicated by Baker and Wharton (1952) and amended by Desch et al. (1972),

Bukva (1996) and Izdebska and Rolbiecki (2016). It is characterized by the presence of a male genital opening on the epistome of gnathosoma. Furthermore, gnathosoma is clearly separated, with well-developed membrane capitulum; pedipalps with relatively long, clearly separated segments. Legs with five well-developed, clearly separate free segments and two massive claws on each tarsus, strongly bifurcated at the end. In larvae, one pair of long, vimineous, and well-developed setae present at

inner edge of anterior margin of basal segment of pedipalps ( Figs. 1 and 2 ).
