Euconnus (Euconnus) iouzensis Hoshina & Nakata ; here placed in Euconnus s. str.

Remarks. This species is known to occur in Honshu, and it belongs to the E. fustiger group. It was described as reaching the body length of 1.70‒1.80 mm, which seems to be distinctly more than in E. fustiger . However, the only known female of E. raucus falls within this range, and it cannot be excluded that these two species are identical. The aedeagus illustrated by Hoshina & Nakata (2018: figs. 3‒5) is slightly distorted, the ventral apical plate is partly flipped out ventrad, and therefore the endophallus is slightly displaced in relation to intact aedeagi. Status of this species is currently not possible to clarify; it may be a distinct species, or may turn out to be identical with E. raucus .

Hoshina & Nakata (2018) placed this species in the subgenus Euconophron (currently a junior synonym of Eupentarius). However, E. iouzensis does not show diagnostic characters of this subgenus, and its placement is here corrected to Euconnus (s. str.).
