Metaphycus garmon Guerrieri and Noyes 2000: 181. Holotype ♀ (BMNH), Italy.

Female.

Body length, including ovipositor, 0.8-1.2 mm. Head orange yellow; antenna (Fig. 29) with radicle brown except pale base; scape brown yellow with an elongate black strip on dorsal margin on outer surface except base; pedicel pale yellow in apical half, dark brown in basal half; F1-F3 black, F4 pale brown and becoming progressively paler to apex, F5-F6 white, clava black; neck of pronotum dark brown, posterior margin white, lateral spots relatively small but distinct; mesoscutum and scutellum orange, sometimes anterior margin of mesoscutum brown; sides and posterior margin of mesoscutum and axillae conspicuously bordered brown; setae translucent, silvery in most lights; tegula white with apex brown; metanotum orange; mesopleuron yellow; prosternum and mesosternum pale yellow; legs (Figs 32-34) mainly pale yellow except pretarsus brownish; fore wing infuscate in basal 3/5, with a darker area beneath marginal vein; venation yellow-brown; hind wing hyaline; propodeum medially orange; gaster orange, gonostylus orange.

Head about 4 × as wide as frontovertex, head with polygonally reticulate sculpture, mesh size slightly less than size of one eye facet; frontovertex about one-fourth head width; ocelli forming an acute angle about 40°; eye not quite reaching occipital margin, separated by much less than diameter of a facet; frontovertex subparallel and from anterior ocellus slightly wider anteriorly; scrobes shallow and U-shaped; antenna with scape 4 –5× as long as broad; funicle with F1-F3 smallest, subequal and subquadrate, F4-F6 becoming larger towards apex; linear sensilla only on F5 and F6; clava 3-segmented, its apex rounded; mandible relatively broad with three subequal, apical teeth; palpal formula 3-3 (Fig. 30), notaular lines reaching about 0.7 × across mesoscutum; fore wing venation and setation as in Fig. 31; cercal plate about in the 0.6 × of gaster; ovipositor (Fig. 35) slightly exserted, 4 –5× as long as gonostylus.

Male.

Generally very similar to female except for body length, coloration of antenna, genitalia and solid clava. Antenna flagellum generally pale brown; aedeagus with two digital spines.

Host.

Unknown.

Distribution.

China (Beijng, Jiangsu, Shanxi) (Fig. 85); France, Greece, Italy, Spain, Turkey ( Guerrieri and Noyes 2000).

Material examined.

China: 1 ♀, Beijing, Haidian, 20.VI.2010, Coll. D. K. Zhou; 1 ♀, Beijing, Changping, 20.IX.2008, Coll. F Yuan; 1 ♀, Jiangsu, Nanjing, 18.VI.2012; 1 ♂, Jiangsu, Nanjing, VI. 2011; 2 ♀♀, Shanxi, Wutai Mt., 16.VII.2006, Coll. Y. Z. Zhang

Diagnosis.

Scape brown yellow, the outer surface with an elongate black strip along dorsal margin (Fig. 29); fore wing infuscate in basal 3/5, with a darker area beneath marginal vein; scape 4 –5× as long as broad; ovipositor slightly exserted, 4 –5× as long as gonostylus (Fig. 35). This species is similar to Metaphycus petitus in general coloration, antennal structure and ovipositor length. Metaphycus garmon can be separated from Metaphycus petitus by the coloration of the fore wing and black strip along dorsal margin ( Guerrieri and Noyes 2000).
