Eurytyloides umbrinus sp. nov.
Etymology. The name umbrinus refers to the dark and shaded colouration of the species.
Description. (Male unknown). Fore wing length 3.6 mm. Antenna with 17 flagellomeres, with multiporous plate sensilla evenly distributed also on ventral surface of the flagellomeres. Face broad, centrally elevated and with two shallow depressions on either side as described for the other species of the genus; mainly coriaceous, smoother in the depressions. Clypeus separated from face by a distinct groove, slightly elevated basally, remainder flat, very weakly bilobed, mainly smooth. Head very strongly constricted behind compound eyes. Mesoscutum smooth, very finely punctate, with notauli indicated by rugose sculpture; scutellum smooth and finely punctate, with lateral carinae only present on basal third. Mesopleuron entirely smooth and shining, sternaulus weakly impressed, epicnemial carina complete ventrally. Metapleuron short, smooth and shining. Propodeum with basal and petiolar areas enclosed but with basal transverse carina partly reduced; lateral longitudinal carina reduced on basal half, present and parallel to petiolar carina on apical third; areas between carinae finely rugose. Fore wing areolet open, vein 1cu-a opposite vein M; hind wing with one basal hamulus, vein CU+cu-a broken slightly below middle. Metasoma 1.6 times longer than head and mesosoma combined, strongly compressed, knife-like from about middle of third tergite; hind margins of tergites 3 to 6 strongly concave; tergite 1 without longitudinal carinae but almost completely covered by fine longitudinal striae, 1.45 times longer than apically wide; tergite 2 with numerous longitudinal striae on basal third, tapering towards apex, 1.55 times longer than basally wide, remaining tergites smooth and shining, evenly setose. Second and third tergites with spiracles on the laterotergites, distinctly below lateral folds; lateral fold only present basally on tergite 3. Ovipositor sheaths straight, parallel-sided, rather narrow, with tip closed apically; smooth and shining, with setae over entire length except for extreme base.
Colouration of females. Antenna dark brown. Head and mesosoma dark brown, face with a small yellow central face patch, yellow on mouthparts, hind corner of pronotum, tegula, subtegular ridge, upper mesepimeron; scutellum dark. Legs orange, fore coxa yellow, mid and hind coxae black; femora orange; hind tibia and tarsus orange. Metasoma brown, somewhat darker on tergite 1 (however, the only specimen at hand had been stored in ethanol for almost 20 years, and might originally have been darker).
Similar species: Eurytyloides umbrinus can be distinguished from the two species from Japan by the largely coriaceous face, and from the Russian E. zinovjevi Manukayn by the stouter first tergite (1.4 times longer than wide compared to more than 1.6 times in E. zinovjevi ), the shorter and less strongly compressed metasoma (1.6 times longer than head and mesosoma combined, compared to 2.1 times in E. zinovjevi ), and by the shape of the face.
