Materials examined. Four males and six females, Kamimaki , Ina city, Nagano Pref., Japan, 26.VII.2024, S. Hashizume ( KUM) ; two males and one female, Daitô-jinja , Minamidaitô-jima Island, Okinawa Pref., Japan, 27. VI.2023, T. Kinoda ( KUM) .

Diagnosis. Dalotia coriaria differs from other species of Dalotia by the following characteristics: apical margin of male tergite VIII dentate (fig. 55G in Yosii & Sawada, 1976; 5A in Lee et al., 2024); median lobe of male aedeagus with large suspensoria and long sclerites (figs. 55K in Yosii & Sawada, 1976; 6A & B in Muona, 2023; vagina with two pairs of sclerites ( Fig. 3D View FIGURE 3 ).

Additional description. Male. Tergites IX, X, and sternite IX shown in Figs. 3A & B View FIGURE 3 .

Female. Tergites IX, X, and sternite IX shown in Figs. 3C & D View FIGURE 3 . Vagina weakly sclerotized, semicircular, with two pairs of sclerite ( Fig. 3D View FIGURE 3 ). Spermatheca: head elongate, without umbilicus; stem short (about twice as long as spermathecal head), helically coiled once around base ( Fig. 3D View FIGURE 3 ).

Distribution. Japan: Honshu, Minamidaitô-jima Island (new record); cosmopolitan.

Habitat. This species is mainly collected from piled grasses.
