Diagnosis. Among the Japanese species of Strigiphilus , this species is easily identified by (1) a short preconal area of the head with anterior margin slightly concave ( Figs 2, 5 ), (2) sexually dimorphic antennae ( Figs 2, 5 ), (3) the shape of dorsal anterior plates ( Figs 3, 6 ), and (4) the morphology of the male genitalia ( Fig. 4 ).

Material examined. Type specimens. Ex Strix uralensis hondoensis : Syntypes of Strigiphilus fukuro : 1♂ (slide-mounted), Fukuro [= Strix uralensis hondoensis, in Katakana ], Nagano Prefecture [in Kanji], Japan, 24 Dec. 1916 ( ELKU); 2♂, 5♀, 9N (preserved in alcohol) same data ( ELKU). Slide-mounted syntypes are labeled as “(1) Syntype / Strigiphilus fukuro / Uchida, 1948 / det. Shimada & Yoshi, 2020; (2) Nagano Pref. / (24. xii. 1916)/ ex Strix uralensis ” ( ELKU); 1♀ (slide-mounted #010693510) (1) “ Strigiphilus fukuro Uchida, 1948 / T. Clay det./ PARA- TYPE ” [no holotype designation was made in the original description by Uchida (1948), therefore this specimen is actually a syntype]. (2) “ Strigiphilus fukuro n. sp. / Fukuro [in Katakana]/ Shinshu [in Kanji = Nagano Prefecture] 33” ( NMHL). Data taken from NHML online database accessed on 23 Apr. 2020 —https://data.nhm.ac.uk
