365B87E2FFB88A57FD1151D6D6F3F9B3.taxon	etymology	Etymology: from the latin septentrionalis which means northern. This name has been assigned to this species because of its distribution. The type species of the genus has been named australis, which means southern, and matches with its distribution in the Austral Chilean and Argentinean Patagonia. This new species, however, is distributed in a more northern location in Chile.	en	Carvajal, Máriom A., Faúndez, Eduardo I., Rider, David A.

365B87E2FFB88A57FD1151D6D6F3F9B3.taxon	discussion	Discussion: This species can be differentiated from Ea australis because of the shape of pronotum which is larger and wider; with sides more inclined in Ea septentrionalis (see figs. 1 and 2). The pygophore in ventral view is wider with lateroposterior edges convex in Ea septentrionalis (Fig. 4); whereas this structure is compact with lateroposterior edges nearly straight in Ea australis (Fig. 3). The same structure is wide in caudal view with parameres occupying a bigger relative area in Ea septentrionalis (Fig. 6); whereas the pygophore is more compact and truncate, with parameres occupying a less relative area in Ea australis (Fig. 5). The parameres are lanceolated with a wide apex and having a process in the apex that looks like a spine oriented backwards in Ea septentrionalis (Fig. 8); whereas the parameres are lanceolated, without a wide apex and without any process in Ea australis (Fig. 7).	en	Carvajal, Máriom A., Faúndez, Eduardo I., Rider, David A.
