Etymology — The prefix para is Latin meaning "near" and refers to the similarity the of the new species with the species
Euphthiracarus netron
Niedbała et Starý, 2014
.
Comparison — The new species is distinguishable from the similar
E
.
netron
Niedbała et Starý, 2014
by the reticulation of body surface (versus punctuation of surface), presence of two pairs of lateral carinae of prodorsum (versus one pair), slightly different shape of sensilli, with head like elongated spindle (versus short spindle), longer exobothridial setae

, longer than distance between setae
le
and

of mentum than distance between them (versus setae
