Abstract

<i>Microplitis fujianica</i> Song and Zhang, sp.nov. <p>(Figs 1–9)</p> <p>FEMALE. Body length 2.6 mm, fore wing length 2.6 mm. Head. 1.6 × as wide as long and not broadening behind eye in dorsal view. Vertex and upper temple densely punctured; ocelli small, forming a high triangle, imaginary tangent of posterior margin of median ocellus far away from posterior ocelli, OD: OOL: POL = 0.4: 0.9: 1. Face approximately quadrate, 1.1 × as wide as high, covered with dense hairs, inner margins of eyes nearly parallelsided. Antenna longer than body (20: 15), F12–15[JJ10] approximately 2.4–2.7 × as long as wide.</p> <p> <i>Mesosoma</i>. Narrower than head (4.6: 5.5), length: width: height = 8.1: 4.6: 6.1. Pronotum rugose-punctate with upper pronotal groove absent. Mesoscutum generally finely rugose-punctate, densely hairy; notaulus slightly impressed, reticulate-punctate, meeting posteriorly to form a slightly sunken rugose-punctate area; medial carina indicated only by slight rugosity; scutellar sulcus divided by five carinae; scutellum in low triangle, weakly rugosepunctate, posteriorly with rugose-punctate band medially. Propodeum coarsely scrobiculate with distinct, percurrent medial longitudinal carina.</p> <p> <i>Wings</i>. Fore wing 1-R1 1.7 × and 1 × as long as the distance from itself to apex of marginal cell and the length of stigma, respectively; r arising from about middle of stigma, about as long as 2-SR; areolet approximately quadrangular; first discal cell 1.4 × as wide as high, 1-CU1: 2-CU1 = 0.9: 1.9. Hind wing with 2a-M: 2r-m = 1.8: 0.8; margin of vannal lobe convex and hairy.</p> <p> <i>Legs</i>. Hind coxa small, approximately as long as T1; both inner and outer spurs of hind tibia approximately equal, 0.2 × as long as basitarsus.</p> <p> <i>Metasoma</i>. Longer than mesosoma (11: 8.1). T1 sub parallel-sided, slightly narrowed posteriorly, its length: basal width: apical width = 3.1: 1.4: 1.1, slightly depressed at base, weakly rugose punctured except for apical swelling smooth. T2 nearly triangular with apical width: central length = 3.6: 1.4; T3 slightly longer than T2 (1.6: 1.4), T3 and the following tergites smooth, shiny with sparse hairs. Hypopygium small, near to tip of metasoma, acute; ovipositor sheath approximately as long as fourth hind tarsus.</p> <p> <i>Colour</i>. Reddish black. Antenna brown except for scape mostly bright yellow; maxillary palp, labial palp and tibial spurs pale yellow; tegula reddish yellow. Stigma yellowish brown except for its basal patch adiaphanous; veins brown; wings colourless. Legs bright yellow to yellow except for basal 2/3 hind tibia whitish yellow, remainder hind tibia and tarsus yellow brown. T1 dark yellow, T2–T5 bright yellow, apex of metasoma yellowish brown.</p> <p> <b>Variation.</b> Body length 2.4–3.1 mm</p> <p> <b>Male.</b> Fore wing 1-CU1: 2-CU1 = 0.6: 1.5–1.8; spurs of hind tiba about the same length and 0.3 × as long as basitarsus; antenna thick and long.</p> <p> <b>Host.</b> Unknown.</p> <p> <b>Material examined.</b> Holotype female: CHINA, Jicun, Ninghua, Fujian, 22-?-1990, Coll.

The latter has stigma with basal patch hyaline, hind coxa reddish brown, and areolet approximately triangular.</p>Published as part of <i>Zhang, Wangzhen, Song, Dongbao & Chen, Jiahua, 2017, Revision of Microplitis species from China with description of a new species, pp. 296-300 in Zootaxa 4231 (2)</i> on pages 297-299, DOI: 10.11646/zootaxa.4231.2.12, <a href="http://zenodo.org/record/291237">http://zenodo.org/record/291237</a&gt
