Description
Trechnites flavipes (Mercet), new record for China
(Figs. 6 A−C)
Metallon flavipes Mercet, 1921: 437, Lectotype ♀, Spain (BMNH), designated by Noyes (1981: 177).
Trechnites flavipes Mercet; Hoffer, 1960: 111; Guerrieri & Noyes, 2009: 253−256.
Material examined. CHINA, 2♀♀, 7♂♂, Xinjiang, Altai, 14.VI.2023, Coll. B.Y. Zou.
Diagnosis. Body length 1.1–1.3 mm, generally dark brown with bright metallic green sheen on mesoscutum, scutellum and sides of gaster; tegula dark brown; apical half of scape brown, the rest yellow; basal half of pedicel brown, funicle and clava yellow; legs yellow (Fig. 6A); fore wing hyaline, venation brown. Ocelli forming an obtuse triangle; malar space approximately 0.4× as long as eye height; scape 5× as long as broad; F1–F4 approximately as long as broad, F5 slightly broader than long (0.9 ×); linear sensilla on F4–F6 and clava. Mesoscutum with notauli complete, reaching posterior margin; scutellum more deeply sculptured than mesoscutum. Fore wings hyaline, 2.3× as long as broad; venation brown; legs yellow; last tarsal segment brown; fore tibia sometimes suffused with brown; ovipositor slightly exserted, OL about 1.0× MT.
Remark. Among the specimens examined, some have a scape brownish in the apical half while others have the scape completely light colored; we consider this variation within a species. Guerrieri & Noyes (2009: 253) also mentioned that apical half of scape is brown while the rest is yellow. However, the flagellum in the Chinese specimens is also light brown, similar to the apex of the scape, and not yellow as in the European material (Guerrieri & Noyes, 2009). We consider this also as variability within the same species.
Host. An unidentified psyllid on Halimodendron halodendron (Pall.) Voss; Eulecanium franconicum Lindinger (Herting, 1972; Trjapitzin, 1989).
Distribution. Armenia (Trjapitzin, 1989); Czech Republic (Kalina, 1989); Denmark (Trjapitzin, 1989); France (Trjapitzin, 1989); Hungary (Trjapitzin, 1989); Italy (Guerrieri & Noyes, 2009); Kazakhstan (Trjapitzin, 1989); Mongolia (Trjapitzin, 1989); Poland (Herting, 1989); Russia (Trjapitzin, 1989); Spain (Noyes, 1981); Turkey (Trjapitzin, 1989); China (new record).
