description: Euxestonotus (Cylindrostonotus) lissogastrus sp. n.
Fig. 10
Etymology: The specific name from a combination of Greek lisso (smooth), combined with the Latin gaster (ancient Greek gastêr), i.e. the abdomen behind the petiole; in reference to the unusually smooth metasoma having no segmentation behind T1.
Diagnosis: Sufficiently given above, in the diagnosis for the subgenus.
Description:
Female.
Body length 1.05–1.50 mm. Black; A1–A2, mandibles and legs including coxae medium brown with trochanters, base and apex of femora, entire fore tibiae, basal two-thirds of mid and hind tibiae, and segments 1–4 of all tarsi light brown; A3–A10 dark brown. Head from above (Fig. 10) 2.0× as wide as long, 1.1× as wide as mesosoma; occiput rather weakly, transversely reticulate-coriaceous; hyperoccipital carina faintly evident; vertex finely reticulate­coriaceous laterally (not transversely so), between ocelli smooth and with weak transverse striae medially; frons smooth on mid area in upper half, finely reticulate here towards sides, in lower half with weak, oblique reticulate­coriaceous sculpture. Eyes bare. OOL:LOL= 4:5. Head in frontal view 1.3× as wide as high. Antenna with A1 0.9× as long as height of head, longer than distance between inner orbits (14:12); A2 as long as A3–A4 combined; A4 twice as long as A3, hardly longer than wide; A5 about 1.25× as long as wide; A7–A10 forming a weak clava; A7 1.5× as long as A6; A9 1.5× as long as wide, as long as A10. Mesosoma (Fig. 10) nearly 1.5× as long as wide, 1.2× as high as wide. Sides of pronotum smooth except for weak reticulate microsculpture in upper anterior part. Mesoscutum with sparse, scattered setae, smooth except for reticulation on slightly less than anterior half of mid lobe; notauli distinct and complete, almost parallel, in extreme posterior part slightly diverging; hind margin slightly concave; scuto-scutellar grooves absent. Mesopleuron smooth. Scutellum sparsely and evenly setose, smooth, exactly at level with mesoscutum, slightly sloping behind. Metapleuron smooth, with rather sparse pilosity all over. Propodeal carinae short, parallel; much of the transverse area between them smooth. Fore wing clear, almost reaching tip of metasoma, two-thirds as long as entire body, 2.5× as long as wide, with very sparse and inconspicuous microtrichia; marginal cilia 0.09× width of wing. Hind wing 6.4× as long as wide, with two hamuli; marginal cilia hardly 0.3× width of wing. Metasoma (Fig. 10) 1.3–1.5× as long as head and mesosoma combined, as wide as mesosoma, 1.3× as wide as high. T1 evenly covered by about ten longitudinal carinae. Rest of metasoma consisting of one large fused tergite, this having short longitudinal striae anteriorly, the longest lateral ones slightly shorter than T1, the medial ones hardly half as long as T1, rest of tergite smooth and bare.
