Euconnus miyatai Hoshina, 2019a: 51 .

Euconnus (Euconnus) miyatai Hoshina; here placed in Euconnus s. str.

Remarks. This species is known to occur in Honshu and Shikoku, and it is yet another member of the difficult E. fustiger group. It was described based on a single male whose body length is similar to that of E. raucus (i.e., 1.70 mm), and several other species of this complex, all with unclear status. Hoshina (2019a) stated that E. miyatai is most similar to E. kojiroi, but it differs in having a “hornlike projection” near the apical margin of the median lobe. The illustration of the aedeagus in Hoshina (2019a: figs 10‒12) shows a strongly distorted genital organ, with a partly extruded endophallus that lacks any sclerotized structures. The dorsal apical plate indeed is illustrated with a distal median elongate projection, which clearly differentiates this species from E. kojiroi, but due to distortions identifications may be difficult, if not impossible. Euconnus miyatai seems to clearly differ from E. fustiger in the same feature as from E. kojiroi, and also in a distinctly larger body, but it is impossible to know whether it is different from E. raucus or not. Status of this species remains unclear, and identifications based on the original description may not be possible.

Hoshina (2019a) did not place this species in any subgenus. As all other members of E. fustiger group, E. miyatai belongs in Euconnus s. str.
