Figures 68–71

Description: Female. Length 2.55 mm. Color: generally ebony black; with the exception of A 5, mandible (except for very tip), palpi, tegula, legs including coxae, yellowish; hind coxa slightly darker than remainder of legs; wings clear, without cloud of pigmentation below marginal, stigmal veins.

Head (Figs. 69–71): vertex, occiput, frons (except facial striae), upper gena smooth, without microsculpture, with minimum appressed minute setae; upper frons, interocellar space glabrous; eye glabrous; LOL slightly greater than OOL; occipital carina fine, but complete, with minuscule crenulation; frons without median keel, but shallow depression present above antennal insertion; facial striae dense, reaching inner orbit, reaching not beyond lower third of height of eye, very short posterior to malar sulcus; clypeus triangular, smooth, anterolateral corners minute; rim of torulus confluent with dorsal margin of clypeus; antenna remarkably slender: A 1 5.4 –6.0 times as long as wide; A 2 2.3 times as long as wide; A 3 3.6–3.8 times as long as wide; flagellum with fairly short setae; claval formula A 6 –A 12 / 2 - 2 - 2 - 2 - 2 - 2 - 1.

Mesosoma (Figs. 70–71): transverse pronotal carina sharp, slightly arcuate, curved forward medially, anterolateral corners angular, but not spikelike; vertical epomial carina present, distinct in upper half, somewhat irregular ventrally; horizontal epomial carina complete, sharp, pronotal shoulders well developed, with row of foveolae both along the horizontal carina and adjacent to mesoscutum, moderately developed, nearly smooth between foveolae; lateral pronotum with large glabrous field, with very delicate microsculpture; netrion well defined by foveolae, considerable micropilosity; mesoscutum with middle lobe smooth and shining, entire surface, particularly posterior two-thirds, regularly covered with setigerous punctures, setae semidecumbent, lateral lobe of mesoscutum almost entirely glabrous, with only few setigerous punctures near posterior notaulus; admedian lines present, fine; notaulus complete, rather narrow, finely foveolate, subparallel; parapsidal line absent or faintly indicated; transscutal articulation well developed, posterior flanking foveolae large; scutellum without microsculpture, with only few setigerous punctures; scutellar spines short, pointed, slightly incurved, distinctly shorter than length of scutellar disk; mesopleural carina absent; dorsal portion of mesopleuron smooth, glabrous, mesepisternum smooth, with fairly dense appressed pilosity; acetabular carina sharply raised; chain of foveolae along posterior margin of mesopleuron well developed, extending ventrally to mid coxal cavity; metapleuron with dense pilosity, both upper and lower parts almost smooth, without microsculpture; propodeum with fine pilosity, almost without medial depression, but median keels well-developed; wings almost clear, widely surpassing tip of metasoma; basal vein, M, Cu, Rs nebulous, with delicate infuscation under marginal vein; postmarginal vein stublike, extremely short; stigmal vein short, slightly curved apically; legs extremely long and slender, femora very weakly incrassate.

Archaeoteleia simulans  , n.sp., paratype female ( OSUCAbout OSUC 146493), Lateral habitus;, head, frontal

view; 70, head and mesosoma, lateral view; 71, head and mesosoma, dorsal view. Scale bars in millimeters.

Metasoma (Figs. 68, 71) relatively short, length 2.4 times width, most terga with rather long, scattered, semierect hairs; T 1 entirely longitudinally costate except for narrow, smooth band along posterior margin, horn not or only weakly developed, anterior margin with only moderate elevation, length of T 1 0.5 times width; length of T 2 0.5 times width, strongly costate throughout; length of T 3 0.4 times width, costae finer than on T 2, both T 2, T 3 with narrow smooth band along posterior margin; length of T 4 0.5 times width, with finer longitudinal costae, larger smooth area posteriorly; length of T 5 0.5 times width, predominantly with very short longitudinal rugulosity anteriorly, mostly smooth in posterior half; T 6 very short, bluntly triangular, length 0.8 times width.

Male. Differing from the female in the following characters: both A 4 and A 5 with keels, keels not exceeding basal third of antennomere; length of A 1 4.3 times width; length of A 2 1.3 times width; length of A 3 1.8 times length of A 1; propodeal keels less pronounced than in female; all metasomatic terga longitudinally costate, but progressively finer, on T 4 only anterior half with longitudinal sculpture.

Diagnosis. Most similar to A. araucana  , distinguished by the even coverage of distinct setigerous punctures on the entire middle lobe of the mesoscutum, and the low and completely striate bulge on T 1 in the female.

Etymology. The specific epithet simulans  , derived from Latin for imitate or copy, refers to the similarity of this species to Archaeoteleia araucana  .
