Hoplocampa phantoma Zinovjev, 1993

Hoplocampa phantoma Zinovjev, 1993: 31–33 . Holotype ♀, not examined, in ZISP. Type locality: Russia [Far East], Khabarovsk Terr., Khekhtsir , 24 km S Khabarovsk.

Note. The characters in the key, and our illustrations, are from specimens collected in the Russian Far East. According to Zinovjev (1993), the specimens from Sverdlovsk oblast [W. Palaearctic] differ from Far Eastern ones, in having a shorter ovipositor (the lower end of the range given below), and slight [unspecified] differences in the male genitalia.

Additional description. Body length: 3.3–3.8mm. Clypeus narrowly and deeply emarginate. Pale body colour yellowish. Female: Valvula 3 and valvifer 2 combined length in lateral view 1.03–1.31 as long as metafemur without trochantellus. Lancet: Fig. 80 . Male: penis valve: Figs 98–99 .

Total number of specimens examined: 9.

Similar species. Superficially similar to alpina , especially in coloration, from which it is externally distinguishable only in the female sex: see key. The lancet of phantoma ( Fig. 80 ) is narrower in relation to its length than that of alpina ( Fig. 77 ), and phantoma has rows of ctenidial teeth on annuli ca. 1–7 ( alpina : rows of teeth only on basal 2–3 annuli). The penis valve of phantoma ( Figs 97–98 ) differs markedly in the profile of the valviceps and some details, such as the gap in the dorsal sclerotised strut just anterior of the valviceps apex, from all other West Palaearctic Hoplocampa species.

Life history. Host plants: unknown, but Zinovjev (1993) considered that these could be Sorbus species; perhaps S. sibirica in the Urals, and S. amurensis in the Far East.

Distribution. Russia. Northern Urals (Sverdlovsk oblast), and the Far East ( Zinovjev 1993).

Occurrence in Sweden: not recorded, and not expected.

Specimens examined. Russia: Primorskiy Kray; 8♀ (DEI-GISHym83552) 1♂ (DEI-GISHym83553), Sa- marka 70 km N, Chuguyevka, Gordeyevskaya Mt. , + 44.76667°N + 134.21667°E, 29.05.1993, leg. A. Taeger ( SDEI) .
