Female: Body length, including ovipositor, 0.7–0.8mm. Frontovertex orange; orange in ocellar area, orange between occipital margin and posterior ocelli; gena with brown-yellow from occiput to base of mandible; mouth margin yellow below torulus; rest of head, except occiput, white; antenna (Fig. 30) with radicle very pale brown; scape mostly black only extreme base and apex white; pedicel dark brown in proximal half otherwise white, F1–F4 dark brown, F5–F6 white, clava dark brown, becoming slightly paler towards apex, apex paler brown; occiput with a large black area above foramen, rest white;neck of pronotum black, posterior margin brown, lateral spots relatively large and distinct, rest brown; dorsum of thorax brown-yellow; sides and posterior margin of mesoscutum and axillae inconspicuously bordered yellow-brown (Fig. 34); setae translucent yellow, silvery in most lights;tegula white only apex pale brown; metanotum dark brown; mesopleuron pale yellow; prosternum and mesosternum white; legs (Figs 35–37) mainly pale brown-yellow; fore wing (Fig. 32) hyaline, venation yellow-brown; hind wing hyaline and with linea calva interrupted; propodeum medially dark brown; gaster dorsally brown, side and venter white; ovipositor sheath pale yellow.
Head with polygonally reticulate sculpture and mesh size slightly less than that of one eye facet; ocelli forming an angle of about 45°; eye not quite reaching occipital margin, separated by much less than diameter of a facet; eye margins subparallel with frontovertex slightly wider anteriorly; scrobes shallow and U-shaped; antenna (Fig. 30) with scape about 2.3? as long as broad; funicle with F1–F4 smallest, subequal and transverse, F5 a little larger, F6 largest and quadrate, linear sensilla only on F5 and F6; clava 3-segmented, its apex rounded; mandible relatively broad with three subequal, apical teeth; palpal formula 2-2 (Fig. 31), notaular lines reaching about 0.5? across mesoscutum (Fig. 33); fore wing venation and setation as in Fig. 32; ovipositor (Fig. 38) slightly exserted, about 4.7? as long as ovipositor sheath.

The species is named after Professor Sanan Wu, who helped to identify many hosts of Encyrtidae.
Antenna with radicle very pale brown; scape mostly black, only extreme base and apex white, about 2.3? as long as broad; legs mainly pale brown-yellow; ovipositor slightly exserted, about 4.7? as long as ovipositor sheath.This species is similar to Metaphycus fusiscapus in colour and size. It can be separated from the latter as follows: scape about 2.3? as long as broad (in fusiscapus, scape about 2? as long as broad); mid and hind tibiae immaculate (Fig. 36), at most with a fuscus spot near base of mid tibiae (in fusiscapus mid and hind tibiae with distinct dark brown marking).
