(Figs. 8J, 9I, 10I, 11I, 17L, 18L)
Physatocheila veteris Drake, 1942: 10. Holotype: macropterous ♂, Japan: Hokkaido, Sappora [= Japan: Hokkaido, Sapporo-shi, Minami-ku, Jozankei]; USNM.
Physatochila [incorrect subsequent spelling] veteris: Takeya (1951: 20) (checklist: eastern Asia).
Physatocheila veteris: Drake & Ruhoff (1965a: 338) (catalog); Tomokuni (1987: 117) (distribution); Tomokuni (1988: 652) (distribution); Péricart & Golub (1996: 56) (checklist: Palaearctic); Yamada & Tomokuni (2012: 200) (monograph); Ban (2013: 31) (distribution); Maehara (2013: 167) (distribution); Maehara (2014: 60) (distribution); Yamada & Ishikawa (2016: 432) (checklist: Japan); Ishikawa (2017: 63) (distribution); Nakatani (2019: 92) (distribution).
Specimens examined. Non-types (2 ♂♂ 5 ♀♀), JAPAN: Hokkaido: Nukabira, 4.viii.1962, leg. Y. Miyatake (1 ♀, KUM); Nukabira, Fujigawa Riv., 14.vi.1967, T. Saigusa (1 ♂, KUM); Sapporo, Moiwa, 9.v.1905, leg. S. Mitsuhashi (1 ♀, KUM). Honshu: Tochigi Pref., Nikko, Kawamata, 5.vi.2013, leg. S. Maehara (1 ♂ 1 ♀, TUA); as above but 12.vi.2017 (2 ♀♀, TUA).
Diagnosis. Recognized among other species of Physatocheila by a combination of the following characters: general color dark brown (Figs. 8J, 9I, 10I, 11I); median spine on head extending beyond bases of frontal spines; rostrum reaching posterior margin of metasternum; pubescence on pronotum less than 0.5 times as long as diameter of compound eye; lateral carinae of pronotum nearly parallel to each other throughout their length, not touching outer margin of paranota at anterior end; paranota incompletely covering pronotal disc in anterior part, not touching each other, not concealing median carina of pronotum, not widened posteriorly, not bulged upward in posterior part, not forming a cyst; outer margin of paranotum nearly straight in its entire length; costal area of hemelytron narrower than subcostal area at widest part, less than 0.5 times as wide as discoidal area at widest part, with 2 rows of areolae in its entire length; and subcostal area subhorizontal, with 4 rows of areolae in its entire length.
Description of genitalia. Pygophore (Figs. 10I, 17L) compressed dorsoventrally, hexagonal in ventral view, strongly concave at anterior margin of dorsum, elevated at center of venter, smooth on surface, irregularly punctate in middle part of dorsum. Paramere (Fig. 18L) expanded in middle part, curved inward in apical part; outer and inner margins covered with pubescence in middle part. Female terminalia (Fig. 11I) pentagonal in ventral view, covered with pubescence.
Remarks. Physatocheila veteris closely resembles P. miyatakei in general appearance but can be easily distinguished from it by the following characteristics: hood low-dome-shaped (Fig. 8J); lateral carinae of pronotum not touching outer margin of paranota at anterior end; and subcostal area with 4 rows of areolae at widest part.
Although the type locality of P. veteris was indicated as “Sappora, Hokkaido, Japan ” (Drake 1942), the label on the holotype mentions “Sapporo, Ḯ山渓” [= Japan: Hokkaido, Sapporo-shi, Minami-ku, Jozankei] (http://n 2t. net/ark:/65665/3f08f65a6-6114-49e3-bea7-2b16f69678c5).
Distribution. Japan (Hokkaido, Honshu).
Host plant. Unknown (Drake & Ruhoff 1965a).
Biology. Adults were observed from May to September (Tomokuni 1987, 1988; Ban 2013; Maehara 2013, 2014; Ishikawa 2017; Nakatani 2019; present study), and nymphs were collected in July (Maehara 2013, 2014). The overwintering stage remains unknown.
