Unknown.</p><p>Comparative notes.</p><p>This species is closely related to  Euconnus impar Sharp, distributed in Japan and South Korea, due to similar morphological features (elongate habitus, subglabrous head and elytra, dense bristles on pronotum sides, loosely assembled tetramerous antennal clubs), and particularly the modified male protarsi. However,  E. imparitus is clearly distinguishable by its significantly different aedeagal structure. The aedeagus of the new species comprises a compressor plate with two short, blunt lateral lobes (vs. with two long, rod-like lobes in  E. impar), a dorso-apical projection of the median lobe that narrows apically in ventral view (vs. apical projection broad and blunt in  E. impar), and parameres broadening near the apices, each bearing three apical macrosetae (vs. parameres slender throughout, each with two long apical setae in  E. impar). Additionally, the apical four antennomeres forming the club of this species appear relatively more elongate than those of  E. impar .</p><p>Distribution.</p><p>East China: Shanghai (Jiading) (Fig. 4 A).</p><p>Biology.</p><p>The male was taken from a mixed light trap sample deployed in an agricultural setting (Fig. 4 E).</p><p>Etymology.</p><p>The specific epithet is derived from a combination of  E. impar, a closely related species, and the Latin suffix “ - itus (- a, - um) ”, denoting an affinity between these two species.</p></div>	https://treatment.plazi.org/id/B9BF696E0AF65B24B48D6068CC860011	Public Domain	No known copyright restrictions apply.

In contrast, the new species possesses an aedeagus that is almost symmetric both externally and internally. Additionally, similarly symmetric aedeagi are found in  E. kelantanensis Franz from West Malaysia and  E. parakelantanensis Franz from north-central Thailand; however, these species are considerably smaller, measuring only 1.20 mm and 1.10 mm in length, respectively (Franz 1970, 1985).</p><p>Distribution.</p><p>East China: Shanghai (Hongqiao) (Fig. 4 A).</p><p>Biology.</p><p>The specimen was collected from a leaf litter sample taken in a secondary mixed forest within Shanghai Zoo (Fig. 4 F).</p><p>Etymology.</p><p>The name is a combination of the Latin adjective “ magnus (great, large) ” and noun “ oculus (eye) ”, referring to the large eyes of this species.</p></div>	https://treatment.plazi.org/id/72F9430C540054B7A61651F1AA31E520	Public Domain	No known copyright restrictions apply.
