Diagnosis. Strigiphilus heterogenitalis can be distinguished from other Japanese species by the following characters (1) its long dorsal anterior plate relative to head length, with DAPL/HL about 0.5 (Figs 17, 20, 22, 25 27), (2) the shape of dorsal anterior plates (Figs 18, 21, 23, 26, 29), and (3) the morphology of the male genitalia (Figs 19, 24, 28).

Material examined. Type specimens. Ex Strix uralensis fuscescens: 1♂, 3♀, paralectotypes of Philopterus cursor laticephalus (ELKU), originally labeled as “ Philopterus cursor laticephalus n. var. / Kiushiu-fukuro [= Strix uralensis fuscescens: in Katakana], Kagoshima Prefecture [in Kanji], 10. III. 1911 ”. Some paralectotypes are slidemounted and labeled as “(1) Syntype / Strigiphilus cursor / var laticephalus / Uchida, 1949; (2) Strigiphilus heterogenitalis / det Shimada & Yoshi, 2020; (3) Kagoshima Pref. / 10. iii. 1911 / ex. Strix uralensis fuscescens ” .

Non-type specimens. Ex Ninox scutulata: 4♂, 4♀ (slide-mounted), Nago City, Okinawa Prefecture, Japan, 9 Jan. 2011, Ichiro Kikuta (SEHU) ; 2♂, 6♀, 1N (preserved in alcohol), same data (YIO) . Ex Otus lempiji pryeri: 3♂, 2♀ (slide-mounted), Ôgimi Village, Okinawa Prefecture, Japan, 1 Jan. 2012, Yutaka Tokuchi (SEHU) ; 3♂, 12♀, 2N (preserved in alcohol), same data (YIO); 2♀ (slide-mounted), Kunigami Village, Okinawa Prefecture, Japan, 8 Mar 2007, Hiroshi Shichiri (SEHU) ; 2♀ (preserved in alcohol), same data (SEHU) . Ex Otus lempiji ssp .: 1♂, 1♀ (slide-mounted), Okinawa Island, Okinawa Prefecture, Japan, 18 May 2010, Conservation & Animal Welfare Trust (SEHU) ; 1♂, 7♀ (preserved in alcohol), same data (SEHU) .

Japanese hosts: Ninox scutulata (Raffles, 1822), Otus lempiji pryeri (Gurney, 1889) (new host association), Otus lempiji ssp., Strix uralensis fuscescens Temminck & Schlegel, 1850 (new host association).

Other hosts. Asio madagascariensis (A. Smith, 1834), Glaucidium brodiei (Burton, 1836), Ninox philippensis Bonaparte, 1855, Otus bakkamoena lettia, Otus manadensis (Quoy & Gaimard, 1830), Otus scops (Linnaeus, 1758), Otus spilocephalus (Blyth, 1846), Uroglaux dimorpha (Salvadori, 1874) (Price et al. 2003: 239) .

Remarks. As discussed above under Strigiphilus cursor, the syntype series of Philopterus cursor laticephalus Uchida, 1949 contains two different species. Specimens of the second species belong to the macrogenitalis speciesgroup and are here identified as S. heterogenitalis . The publication date of S. laticephalus is earlier than that of S. heterogenitalis but, because the lectotype of S. laticephalus was selected from specimens conspecific with S. cursor, the name S. heterogenitalis is retained as valid.
