( Figs 3–5 ) Cryptoserphus gracilis Brues, 1940 : 259 (female). Description. Body approximately 4.3 mm long including ovipositor sheath, but excluding antennae. Hindwing 1.2 mm long, antenna 1.6 mm long. Clypeus narrow, 0.3 times as long as wide and almost 0.5 times as wide as face (distance between eyes). Malar sulcus deep. Mandibles weak and short. Antenna 13-segmented; ratio of antennomere lengths as following: 2.0:1.0:6.0:5.0:4.3:4.0:3.6:3.6:3.3:3.3:2.6:2.6:4.0. Propodeum 0.5 times as long as thorax. Dorsal side of propodeum with two bare elongated lateral fields separated by low simple ridge. Each lateral field 1.7 times as long as wide. Pterostigma almost as long as costal section of radial cell. Radial vein not curved, joining costal vein at 30º. Legs long and thin. Ovipositor sheath 9 times as long as wide, 0.49 times as long as hind tibia. Setation on ovipositor sheath becoming denser distally. Holotype . Female, MCZC , no. 5219. The specimen is fixed in the dorsoventral position between the microscopic slide and the cover slip, so the lateral sclerites are not visible. The mesoscutum and scutellum are absent; seven apical segments of one antennae, left forewing and hindwings are detached and put on the right side of the body. The forewings are heavily deformed, the veins and the pterostigma are poorly distinguishable. The mouth is covered with milky substance.
