Specimens examined. Non-types (macropterous 2 ♂♂ 2 ♀♀) , JAPAN: Honshu: Tokyo, Mt. Takao , 26.vi.1929, leg. S. Hirayama (1 ♀, ELKU) ; Tottori Pref., Tottori-shi, Syouzan , 3526'33.2" N 13416 '03.8"E, 6.xi.2018, leg. Y. Obae (1 ♂, TPM) . Shikoku: Iyo, Omogo , 15.viii.1951, leg. T. Esaki (1 ♀, ELKU) . Kyushu: Bungo, Sobo-san , 26.vii.1935, leg. S. Ôishi (1 ♂, ELKU) ( Fig. 7 ).

Diagnostic characters. Recognized among other species of Tropidocheila by a combination of the following characters: general color brown ( Fig. 1B ); pubescence on dorsum longer than diameter of compound eye; head with five spines ( Fig. 4B ); a pair of frontal spines reaching behind tip of clypeus; median spine reaching level far remote from bases of frontal spines; a pair of occipital spines reaching posterior margin of compound eye; rostrum reaching posterior margin of mesosternum; anterior margin of hood curved outward throughout its length; lateral carinae of pronotum distinct on pronotal disc; paranotum laminate, subhorizontal, with 3 rows of areolae at widest part; costal area of hemelytron with 3 rows of areolae at widest part, as wide as subcostal area at widest part of each; subcostal area with 3 rows of areolae at widest part; discoidal area with 6 rows of areolae at widest part; and sutural area with 8 rows of areolae at widest part.

Distribution. Japan (Honshu, Shikoku, Kyushu); China.

Host plant. In Japan, the host plant of Tingis (Tropidocheila) shaowuana remains unknown ( Yamada & Tomokuni 2012). In China, this lace bug has been collected from Buddleja sp. ( Scrophulariaceae ) ( Jing 1981).

Biology. In Japan, adults were collected in April, from June to August, and in November ( Takeya 1962; Yano et al. 2013; present study). Nymph and overwintering stage are unknown.
