Etymology The name is a combination of ‘ para ’, a Latin prefix that means ‘similar to’ or ‘equal’, and ‘ utriensis ’, which refers to one of the species described in this paper. An adjective.

Posterior margin of sternite VIII bilobed, with narrow median emargination reaching up to ¼ of segment length, lobes obtuse ( Fig. 16E ). Posterior margin of tergite IX with midlongitudinal deep emargination, reaching up to ¾ of segment length ( Fig. 16A ; as in Asenjo 2011 : fig. 12); aedeagus, median lobe broadened at base, apex with moderately deep emargination and rounded processes on each side. pLS thin, with net-like microsculpture, forming elongate flat processes equal in length to pPMS.
