Distribution. Japan (Hokkaido, Honshu, Shikoku, Kyushu), across the Holarctic region. Remarks. Townes (1938) placed this species in the virgata group. However, latungula is different from virgata in the absences of overhang and strip of minutely papillate cuticle on the mesal surface of paramere, and shares the shape of the digitus with virgata and kiuhabona. Thus, this species can not be assigned to any species group.
