Panzeria anthophila (Robineau-Desvoidy)

( Figs 1–2 )

Erigone anthophila Robineau-Desvoidy, 1830: 66 . Syntypes: male and female [lost, see Herting (1974: 5)]. Type localities: France, Yonne (Saint-Sauveur-en-Puisaye [as “Saint-Sauveur”]) and Paris.

[For other synonyms see Herting (1984: 104, as Eurithia ).]

Diagnosis. Apical scutellar setae strong and crossed; parafacial bare; palpus dark brown to black; 3 postsutural dorsocentral setae; anatergite bare; upper occiput with a row of short and strong black setae behind row of postocular setae; 5th abdominal tergite broadly shining black; male 6th abdominal tergite fused mid-dorsally with syntergosternite 7+8.

Description of female terminalia. Rather long; 6th tergite rather broad, entire, with several strong setae on mid-dorsal portion and many short and long, strong setae on posterior portion; 6th and 7th spiracles on anteroventral and submedian portions of 6th tergite, respectively; 6th sternite broad, slightly longer than 6th tergite, rather broadly excavated on anteroventral margin, with some strong setae on mid-dorsal portion and a row of long and strong setae on posterior margin; 7th tergite rather broadly separated into hemitergites on mid-dorsal portion, with a row of rather fine setae on posterior margin; 7th sternite weakly excavated on mid-ventral portion, with fine setae on mid-ventral portion and along posterior margin; 8th tergite reduced to very small hemitergites, without hairs; 8th sternite rather quadrate in ventral view, small, less than 1/3 of 7th sternite, with fine short hairs on posterior portion; epiproct small, triangular in form, with a pair of rather long setae.

Material examined from Japan (all KUM). Hokkaido: 21 males, 10 females from the following localities: Shiretoko, Mt. Rausu (200–900 m); Mts. Daisetu , Aizankei and Ginmeisui; Kushiro, Akanmachi; Ashoro, Kiyokawa and Ashorobuto; Hidaka, Shirarutoro and Mt. Apoinpuri ; Shibecha, Toroko; Sapporo City, Mt. Moiwa. Honshu : 21 males, 12 females from the following localities : Aomori Pref., Zatoishi, Hirosaki City, Mt Bonju, Towada Lake and Tsurugasaki ; Akita Pref., Mt. Hakkodo, Mt. Mitsugamori and Okiagetai ; Iwate Pref., Mt. Waga ; Fukushima Pref., Iitashiobara Town , Shirabu Pass ; Niigata Pref., Mt. Kurohime ; Saitama Pref., Chichibu, Karisaka, Kumotori , Mitsumine, Ogawa, Yokose and Yorii ; Nagano Pref., Hakuba Vill., Mt. Futagoyama, Mt. Hachimori , Ogurogawa Valley (1300 m) and Yakiyama ; Yamanashi Pref., Hirogawara (1500–1700 m) and Mt. Kitadake ; Aichi Pref., Mt. Chausuyama .

Distribution. Japan (Hokkaido, Honshu); China (central to north China, Guizhou, Sichuan, Yunnan, Xizang), Europe (northward to Ireland, Scotland and central Sweden); Mongolia, Nepal *, South Korea, Pakistan *, Russia (West Russia, W. Siberia, S. Siberia, S. Far East), Taiwan *, Thailand * (Northern area), Transcaucasia.

Remarks. This species is widely distributed in the Palearctic Region and common in northern Japan. Tschorsnig (2017) listed two Spilosoma species ( Arctiidae ), two noctuid and one notodontid species with certainty as hosts of this species. We have no host records of this species in Japan.

Mesnil (1972a) redescribed this species in detail under the name Eurythia (= Eurithia ). I have examined many specimens from the northern fringe of the Oriental Region, such as Pakistan, Nepal, northern Thailand, southwestern China (Sichuan, Yunnan) and Taiwan. Some of them appear to exhibit slight differences in the male terminalia from those of northern areas. Here I tentatively treat them as the same species, because I am not sure if these differences are merely geographical variations or specific differences.

Zimin (1957) recorded this species under the name Platychira radicum ( Fabricius, 1794) , with illustration of the male cerci. The male cerci illustrated by him ( Zimin 1957, fig. 5-1) are, however, different from those by Emden (1954), Tschorsnig & Herting (1994), Chao et al. (1998) and Cerretti (2010). Zimin (1957: 535) mentioned the male cerci as flat, wide and beak-like in the key to species of Platychira . I wonder if Zimin (1957) misunderstood this species. The male 6th tergite is fused mid-dorsally with syntergosternite 7+ 8 in this species.
