Diagnostic characters. Recognized among other species of Tropidocheila View in CoL by a combination of the following characters: general color black ( Figs. 1A View FIGURE 1 , 6A, B View FIGURE 6 ); pubescence on dorsum shorter than diameter of compound eye; head with five spines ( Fig. 4A View FIGURE 4 ); a pair of frontal spines reaching beyond tip of clypeus; median spine reaching bases of frontal spines; a pair of occipital spines reaching middle of compound eyes; rostrum reaching middle of metasternum ( Fig. 2A View FIGURE 2 ); anterior margin of hood curved outward throughout its length; lateral carinae of pronotum distinct on pronotal disc; paranotum ridge-shaped, subvertical, with a single row of areolae in anterior half, without areolae in posterior half ( Fig. 2B View FIGURE 2 ); costal area of hemelytron with 2 rows of areolae throughout its length, narrower than subcostal area at widest part of each ( Fig. 2C View FIGURE 2 ); subcostal area with 3 rows of areolae at widest part; discoidal area with 9 rows of areolae at widest part; and sutural area with 11–12 rows of areolae at widest part.

Description of genitalia. Pygophore ( Figs. 3A View FIGURE 3 , 5B View FIGURE 5 ) compressed dorsoventrally, hexagonal in ventral view, elevated at center of venter, concave at anterior margin of dorsum. Paramere ( Fig. 5A View FIGURE 5 ) expanded in middle part, curved inward in apical part; outer and inner margins covered with pubescence in middle part. Female terminalia ( Fig. 3B View FIGURE 3 ) pentagonal in ventral view, covered with pubescence; ovipositor with ovivalvula at base.

Distribution. Japan (Honshu, Kesennuma-Oshima Island, Sado Island, Dogo Island, Nakanoshima Island, Shikoku, Kyushu, Fukue Island); Korea.

In Japan, Tingis ( Tropidocheila) matsumurai inhabits deciduous forests of temperate climate.

Host plant. In Japan, Cornus controversa Helms. ex Prain and C. macrophylla (Cornaceae) have been confirmed as host plants of Tingis ( Tropidocheila) matsumurai ( Maehara 2010, 2014; Yamada & Tomokuni 2012; Komatsu 2016; Ito & Sasaki 2018). In Korea, C. controversa has been confirmed as a host plant of this species ( Ahn et al. 2018).

Biology. Although many tingids generally feed on the abaxial surface of leaves of their respective host plants ( Schuh & Weirauch 2020), several individuals of Tingis ( Tropidocheila) matsumurai were collected from flowers and fruits of the host tree Cornus controversa and C. macrophylla in Japan ( Maehara 2010, 2014) ( Fig. 6C View FIGURE 6 ), suggesting that this lace bug readily feed on the flowers and fruits.

In Japan, adults were collected in almost all seasons; nymphs were collected in June; the overwintering stage is adult ( Takeya 1962; Ishihara et al. 1974; Maehara 2010, 2014; Yamada & Tomokuni 2012; Yano et al. 2013; Komatsu 2016; Hayashi & Kadowaki 2018; Ito & Sasaki 2018; Ikeda et al. 2019; Nishida 2019; Okochi 2019; present study).
