Figures 58–63

Archaeoteleia pygmea Masner 1968: 660 . Original description. Sarazin 1986: 978 (type information).

The original description was based solely on males. It may be supplemented by data from the females:

Female. Length 2.2–3.1 mm. Color: castaneous brown, never with submetallic tinge; antenna abruptly bicolored, A1–A5 bright yellow, A6–A12 nearly black; legs, including coxae, entirely yellow; dorsal part of pronotum, including epomial corners, yellow; lower portion of pronotum, mesopleuron, metapleuron, S1–S2 dark brown to nearly black.

Head ( Figs. 58, 59, 62 ): vertex, occiput, upper frons rugose punctate, punctures bearing short, appressed setae; sculpture along inner orbits with longitudinal rugulosity, central part of frons punctate; upper gena almost smooth, shining; LOL greater than OOL; occipital carina fine, complete, not distinctly crenulate; frons with strong median keel running slightly over half distance from interantennal process to median ocellus; striae of cheeks and face strong, reaching inner orbits; clypeus strongly transversely striate, anterolateral corners strongly projecting, with long erect setae; toruli contiguous with upper margin of clypeus; A1 5.3 times as long as wide; A2 2.7 times as long as wide; A3 1.1 times as long as A2; claval formula A6–A12/2-2-2-2-2- 2-1.

Mesosoma ( Figs. 58, 59 ): transverse pronotal carina extremely sharp, bladelike, produced medially into broad point, with anterolateral corners sharply produced, pointed; vertical epomial carina absent; horizontal epomial carina close to mesoscutum, and shoulders narrow, maximum width about 0.5 tegula width; lateral pronotum predominantly smooth, highly shining, largely glabrous, area above fore coxa with irregular, large, transverse rugulae; netrion vaguely indicated; mesoscutum highly convex, with dense, fine pilosity, interspersed with few, long erect setae, densely punctured, interstices smooth, without microsculpture; admedian lines absent; notaulus absent; parapsidal line absent; transscutal articulation well indicated, crenulate laterally; length of scutellum 0.8–0.9 times length of mesoscutum; scutellar spines curved posteriorly; mesopleural carina running almost in middle of mesopleuron, smooth and shining above; mesopleuron almost entirely glabrous, smooth, shining, without microsculpture, with row of deep foveolae along posterior margin; mesepisternum below mesopleural carina almost glabrous, smooth and shining; acetabular carina present, crenulate; metapleuron densely hairy, with rough rugulosity and deep punctures, without glabrous area; propodeum with shallow excavation medially, punctured, with distinctly finer sculpture than lateral propodeum; submedial carinae present, not projecting, not sharp, abbreviated posteriorly; tegula absent; wings entirely absent; legs relatively short, robust; pretarsal claws very strongly developed.

Metasoma ( Figs. 58, 59 ) short, broadened medially, length 2.1 times greatest width, without bristles amid shorter, semidecumbent pilosity; length of T1 0.5 times width, T1 hump low, distinctly below level of mesoscutum, not higher than propodeum, laterally with longitudinal rugulae, apex of horn smooth, behind horn with confused rugulae; length of T2 0.6 times width, longitudinally rugulose, without interspersed deep punctures; length of T3 0.4 times width; length of T4 0.4 times width; length of T5 0.3–0.4 times width; length of T6 0.8–1.1 times width, densely setose.

Male. The original description may be supplemented as follows: antennal toruli broadly separated from top of clypeus ( Fig. 63 ); “epistomal suture” dorsoventral, running down to clypeal triangle, in form of distinct raised keel; scutellar spine as long as length of disk of scutellum, curved inward toward midline of body, slen- der, long, subparallel ( Figs. 60, 61 ); no keels on propodeum; fore wing with faint pigmented cloud beneath marginal and stigmal veins ( Figs. 60, 61 ).

Diagnosis. The macropterous male is distinguished from all other species of Archaeoteleia by the position of the toruli. These are distinctly separated from the dorsal margin of the clypeus ( Fig. 63 ). The brachypterous female is most similar to A. submetallica , from which it may be separated by the shorter metasoma and the absence of a metallic hue to the body.
