[Japanese name: Hime-tobimushi-hanekakushi] Homalota oligotinula : Sharp, 1888: 293 (original description; type locality: “ Kumamoto ” [ Kumamto-shi , Kumamoto-ken , Kyushu]). Atheta ( Microdota ) oligotinula : Bernhauer & Scheerpeltz, 1926: 634 (catalogue). Platyola oligotinula : Pace, 1984: 54 (transferred to the genus Platyola from the genus Phymatura ). Pseudatheta oligotinula ; Pace, 1992: 242 (transferred to the genus Pseudatheta from the genus Phymatura ; probably based on Sawada (1977)) ; Schülke & Smetana, 2015: 634 (catalogue). nec. Phymatura oligotinula sensu Sawada, 1977: 217 (transferred to the genus Phymatura from the genus Homalota ). Material examined. Type material.

This species was redescribed based on misidentified specimens of Ps. crenulicauda by Sawada (1977) and transferred to the genus Phymatura . However, as Pace (1984) stated that this species belongs to the genus Platyola of the tribe Athetini , not Homalotini . Later, Pace (1992) probably forgot this arrangement ( Pace, 1984 ) and moved this species from the genus Phymatura to the genus Pseudatheta , and this treatment was followed in the later catalogs (e.g., Schülke & Smetana 2015 ; Newton 2022 ). We here place this species again in the genus Platyola .
