Name

Metaphycus transversus Wang & Li & Zhang, 2014 sp. n.Wikispecies linkZooBank linkPensoft Profile

Holotype

China: ♀, Yunnan, Xishuangbanna, 2009.XI.16, Coll. Y. Z. Zhang (IZCAS).

Paratypes

3 ♀♀, the same as holotype (IZCAS).

Female

Body length, including ovipositor, 1.2–1.3 mm. Frontovertex pale yellow; gena with fairly broad, oblique brown area near mouth margin; mouth margin medially pale yellow below torulus; rest of head, except occiput, white; antenna (Fig. 36) with radicle brown; scape with both faces black, dorsal margin black, white at extreme apex; pedicel dark brown in proximal half, white distally, dark brown area extending slightly towards apex externally and internally; F1–F4 brown, F5–F6 pale brown and becoming slightly paler towards apex; clava pale brown, extreme base brown like F6, becoming slightly paler towards apex; occiput with a black area above foramen, otherwise white; neck of pronotum black, posterior margin very pale brown, lateral spots relatively small and distinct; dorsum of thorax mainly orange; sides and posterior margin of mesoscutum and axillae conspicuously bordered brown; setae translucent brown, silvery in most lights; tegula pale yellow; metanotum brown; mesopleuron yellow-white; prosternum white; mesosternum white, sometimes pale brown; legs (Figs 39–41) mainly pale yellow; tibiae proximally dark brown; mid tibia and hind tibia with a pair of dark brown rings at about 0.2× and 0.5×; fore wing (Fig. 38) hyaline, with linea calva interrupted by two setae; venation yellow-brown; hind wing hyaline; propodeum medially dark brown, sides pale yellow; gaster dorsally brown, side and venter white; gonostylus orange. Head about 4× as wide as frontovertex, head with polygonally reticulate sculpture and mesh size slightly less than size of one eye facet; frontovertex about one-fourth head width; ocelli forming an acute angle about 60°; 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; antenna (Fig. 36) with scape about 2.5× as long as broad; funicle with all funicular segments transverse, F1–F4 small, F5 and F6 a little larger, linear sensilla only on F5 and F6; clava 3-segmented, its apex rounded but with a short slightly oblique truncation; mandible relatively broad with three subequal, apical teeth; palpal formula 3-3 (Fig. 37), notaular lines reaching about 0.8× across mesoscutum; fore wing venation and setation as in Fig. 38; cercal plate about in the 1/2 of gaster; ovipositor (Fig. 42) hardly exserted, about 5.8× as long as gonostylus.
Relative measurements: HW 19, FV 5, FVL 8, POL 2.5, AOL 2.5, OOL 1.5, OCL 1, POD 1.5, AOD 1.5, EL 11, EW 8, MS 5, SL 7, SW 2.5, FWL 43, FWW 18, HWL 31, HWW 7, OL 15, GL 3, MT 14.

Male

Unknown.

Host

Unknown.

Distribution

China (Yunnan) (Fig. 84).

Etymology

The new species name is derived from the fact that each funicle segment is strongly transverse.

Diagnosis

Scape black, but apex yellowish white; gena with a fairly broad, oblique brown area near mouth margin; funicle with F1–F6 transverse (Fig. 36); ovipositor (Fig. 42) hardly exserted, about 5.8× as long as gonostylus. Using the key of Guerrieri and Noyes (2000)[1], Metaphycus transversus runs couplet 27 and is close to Metaphycus lounsburyi. Females of Metaphycus transversus can be separated from lounsburyi as follows: scape (Fig. 36) about 2.5× as long as broad (in lounsburyi, scape about 3× as long as broad); dorsal margin of scape black (in lounsburyi, dorsal margin white).
