Archaeoteleia gracilis Masner 1968: 659 . Original description.

The original description ( Masner 1968) may be supplemented as follows:

Head ( Figs. 43–45 ): entirely smooth, shining, almost glabrous; eye glabrous; LOL slightly greater than OOL; occipital carina complete, finely crenulate; median keel weakly developed in lower half of frons; frontal striae along inner orbits not reaching midpoint of height of eye; clypeus smooth, lateral corners strongly protruding; toruli contiguous with upper margin of clypeus; A1 4.7 times as long as wide; A2 3.3 times as long as wide; A3 3.4 times as long as A2; claval formula A5–A12/1-2-2-2-2-2-2-1.

Mesosoma ( Figs. 44–45 ): transverse pronotal carina very sharply raised, arcuate; vertical epomial carina present; horizontal epomial carina present, pronotal shoulders moderately developed; side of pronotum with extensive smooth, shining field; netrion well developed, demarcated by anterior arc of deep foveae, finely sculptured, setose; lateral lobe of mesoscutum smooth, shining, almost completely glabrous, contrasting with heavy, even punctures on midlobe of mesoscutum; admedian lines well expressed; notauli subparallel; parapsidal line present, delicate; posterior margin of mesopleuron with complete chain of deep foveolae reaching ventrally to coxal cavity; metapleuron predominantly glabrous, with only very few small, scattered setae, shining, with row of foveolae along anterior margin and arcuate foveolar line at meson, roughly rugulose above hind coxa, smooth and shining medially; scutellum transverse, length 0.5 times length of mesoscutum, nearly smooth, setose scutellar spines straight, rather short, directed posteriorly; mesopleural carina indicated by two or three parallel, closely spaced rugulae; mesepisternum with distinct rugose punctation in epicnemial corner; acetabular carina fine; posterior margin of mesopleuron with complete foveolate chain extending ventrally to coxal cavity; metapleuron rugulose, densely setose ventrally, above medial line of foveae with narrow smooth, glabrous area, otherwise setose; propodeal keels well developed; fore wing strongly exceeding tip of metasoma, basal vein strongly pigmented, delicate infuscated cloud below marginal vein, postmarginal vein distinctly tracheate, length 3.3 times length of stigmal vein, stigmal vein nearly straight, Rs, M, Cu well-defined by nebulous streaks; hind basitarsus narrow, apex of hind coxa not extending beyond apex of S2, on posterior surface with irregular rugulosity and several transverse wrinkles above apex.

Metasoma ( Figs. 42, 45 ) generally more elongate than A. simulans , length 3.4 times greatest width; T1 with very distinct horn, gently sloping anteriorly, most of surface smooth, without sculpture, in lateral view top of horn reaches top of scutellum, length 0.8 times width; length of T2 0.7 times width; length of T3 0.5 times width; length of T4 0.7 times width; length of T5 0.6 times width; sculpture of tergites, particularly T3– T5, finely longitudinally rugulose, anterior margin of T2–T4 with row of very large foveolae; length of T6 1.0–1.4 times width, with fine scattered setigerous punctures.

Male. Very similar to female; length 2.6–2.9 mm; only A4 with keel.

Diagnosis: Distinguished from A. araucana by the punctate scutellum and median lobe of mesoscutum, this contrasting with the smooth lateral lobes of the mesoscutum..

Comments: The three species A. gracilis , A. simulans , and A. araucana are all very similar. Archaeoteleia gracilis has extremely long, slender legs and antennae, and of these three, has the longest metasoma. This species, together with A. mellea , are the only species so far known south of Chiloé Island.
