Adalia conglomerata (Linneaus)

Coccinella conglomerata Linneaus 1758 (Europe) .

Adalia (Adaliomorpha) conglomerata: Iablokoff­Khnzorian 1982 (Siberia, Ussuri).

Adalia conglomerata: Mader 1929 ; Miyatake 1957 ( Japan); Kamiya 1965a; Sasaji 1971; Bielawski 1984 ( Mongolia).

Coccinella ronina Lewis 1896 ( Japan) .

Adalia ronina: Mader 1931 ; Miyatake 1957.

Distribution. China (Yunnan, Shaanxi), from Japan and the Russian Far East to Europe.

Specimens Examined. (7 total), Yunnan: Lijiang: Wenbishan (2), Yuelongxueshan, collected from Pinus armandii (3), Shaanxi: Ningshan (2).

Remarks. All specimens from Yunnan had spotless elytra like A. destituta Weise figured by Mader (1926 –1934, Plate 18, Fig. 9). One specimen from

Shaanxi has three black spots on each elytron and the other has one spot at calli. We observed this species to feed voraciously on hemlock woolly adelgid in the laboratory. Kamiya (1965a) observed it as predator of Adelges japonicus Monzen.

Genus Oenopia Mulsant Oenopia billieti (Mulsant)

Harmonia billieti Mulsant 1853 (North India).

Coccinella (Synharmonia) billieti: Kapur 1958 (Kashmir, Punjab and Assam).

Oenopia billieti: Iablokoff­Khnzorian 1982 (Himalayas, Bangladesh); Jing 1987 (Tibet); 1992 (Sichuan).

Oenopia pomiensis Jing 1987 (Tibet) , new synonymy

Oenopia gonggarensis Jing 1992 (Sichuan) , new synonymy

Oenopia picithoroxa Jing 1992 (Sichuan) , new synonymy

Distribution. China (Tibet, Sichuan, Yunnan, Shaanxi), India, Bangladesh, Kashmir.

Specimens Examined. (9 total), Yunnan: Lijiang: Heyuan (5), Yuelongxueshan, from Pinus armandii (1), Shaanxi: Ningshan: Huoditang (3).

Remarks. This species has very variable coloration. Kapur (1958, Fig. 9a– d) illustrated four color patterns. We believe that specimens described as Oenopia pomiensis Jing , Oenopia gonggarensis Jing , and Oenopia picithoroxa Jing represent additional color forms of O. billieti . Male specimens from Shaanxi have the color pattern Kapur said was typical of O. billieti . Other male specimens either have elytra with black spots reduced to only one at the base, similar to the description of O. pomiensis ( Jing 1987) , or have elytra that are testaceous with a narrow black margin along the suture, similar to the description and illustration of O. picithoroxa ( Jing 1992) . All the male specimens examined have similar genitalia. The descriptions of O. gonggarensis and O. picithoroxa are based on female specimens ( Jing 1992). Our female specimens have elytral coloration similar that described for O. picithoroxa and an infundibulum similar to that of O. gonggarensis . Although we have not examined Jing’s types, we do not hesitate to establish these synonyms since the various color patterns are associated with similar genitalia. Two other species of this genus from Yunnan, China described by Jing (1986, 1992), Oenopia flavidbruna Jing and Oenopia lanpingensis Jing will likely be found to be conspecific with O. billieti , once more specimens and the types are examined. We observed O. billieti feeding on the hemlock woolly adelgid and it laid eggs on infested foliage in the laboratory.
