A new species of the genus Mirufens (Hymenoptera: Trichogrammatidae) from China.

The new species is similar to the genus type species Mirufens dentipes Girault in form, size and color, but dissimilar in the shape and proportion of antennal funicle. For the type species: funicle Ⅰ length slightly greater than width, funicle 2 width slightly greater than length; while for the new species: both funicles width notably greater than length, total length of two funicles only half the length of pedicel.The new species is also similar to M. brevifuniculata Khan et Shafee, but in th latter the body length is only 0.63mm; frons, vertex, the middle of scutum and scutellum yellow; stigmal vein of the fore wing as long as marginal vein; ovipositor extends from the third segment of abdomen and is invisible. These features distinguish easily the latter from the new species.Holotype (?), paratypes 2 (?)
