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.
