Figures 64-67
Description: Female. Length 3.6 mm. Color: body generally dark brown; prothorax, including side of pronotum, tegula, clypeus, mandible (except tips), radicle, palpi, fore legs, trochanters and tibiae lighter, light brown to yellow.
Head (Figs. 65-67): vertex, frons, gena rugose punctate, covered with fine dense appressed micropilosity, with only very few stiff bristles; eye distinctly setose; LOL less than OOL; occipital carina well developed, complete, distinctly crenulate, particularly at sides; median keel short, delicate, not reaching beyond midpoint of height of frons; facial striae well developed, reaching almost to level of middle of inner orbit; clypeus broadly triangular, with transverse rugulosity; toruli contiguous with upper margin of clypeus; antenna overall relatively short and stout: A1 6.0 times as long as wide; A2 2.3 times as long as wide; A3 1.6 times as long as A2; flagellum with short setae; claval formula A6-A12/1-2-2-2-2-2-1.
Mesosoma (Figs. 66-67): transverse pronotal carina sharp, perfectly straight, with anterolateral corners acute, but not projecting spinelike; vertical epomial carina present, sharp, originating at anterolateral corner, extending toward fore coxa; horizontal epomial carina sharp, running far from mesoscutum, pronotal shoulders very broad, rugose punctate with dense appressed pilosity, several stiff black erect bristles; lateral pronotum deeply concave, predominantly with large smooth shining glabrous area, leaving only dorsoposterior margin with deep punctation; netrion well defined; mesoscutum in lateral view almost flattened, very broad, densely rugose punctate, with dense appressed micropilosity, and scattered erect black bristles; admedian lines short; notaulus complete, deeply incised, distinctly crenulate; parapsidal line present; transscutal articulation deep, distinctly foveolate; scutellum broad, 0.4 times length of mesoscutum, much wider than long, with same sculpture as mesoscutum, with only few stiff bristles; scutellar spines strong, about as long as disk of scutellum, directed posteriorly; mesopleural carina reduced to rudiment, situated anteriorly; mesopleural depression in upper part smooth, shining, glabrous, with several longitudinal keels below tegula, mesepisternum predominantly punctured, with scattered setae; acetabular carina fine, complete; line of foveae along posterior margin of mesopleuron present, but not extending ventrally as far as mid coxa; metapleuron only sparsely setose, predominantly rugose punctate, with several transverse rugae near propodeum; propodeum with scattered setae, irregularly rugulose, deeply excavate medially, medial excavation almost smooth, glabrous, median carinae present, sharply defined, not raised in profile; macropterous, fore wing relatively short, narrow, not surpassing apex of metasoma, reaching posteriorly only to T5, generally moderately infuscate, distinct cloud of pigmentation sometimes present; R between tegula and marginal vein with 10 long, erect, stiff black bristles; postmarginal vein tubular, clearly longer than short stigmal vein; stigma short, curved; basal vein pigmented; M, Cu, Rs moderately pigmented as nebulous veins; legs exceptionally short, stout, especially femora; tibial spurs of mid leg, hind leg unusually long, strong; hind femur strongly incrassate; hind coxa only slightly longer than mid coxa, without transverse wrinkles at apex, deeply punctured.
Metasoma (Figs. 64, 67) short, robust, length 2.6 times width; T1 trapezoidal, length 0.6-0.7 times width, longitudinally costate, trapezoidal, horn short, almost upright, with sharp crest along midline, with deep punctures, without costae; length of T2 0.5 times width; length of T3 0.5 times width; length of T4 0.4 times width; length of T5 0.4 times width; T2-T5 generally longitudinally costate, mid portion of T3-T5 gradually smoother, without costae; length of T6 1.2-1.5 times width, with abundant setigerous punctures.
Male. Very similar to female, even in normally secondary sexual characters; differing as follows: length 3.1 mm; eye slightly smaller; keels present on A4, A5; length of A1 5.6 times width; length of A2 2.1 times width; length of A3 0.6 times length of A1; fore wing variable in length, extending to end of T4 or to tip of metasoma; metasoma with strong, sharp, pyramidal, setose point on anteromedian margin of T1, propodeum with corresponding excavation; length of metasoma 2.2-2.4 times width.
Diagnosis. Distinct among all Archaeoteleia by the flattened mesoscutum, scutellum and scutellar spines; presence of strong, acute vertical epomial carina; and the stout, strong legs. This species is comprised of robust, stout individuals. The only other species with A1 longer than A3 is male A. pygmea. From that species, A. robusta is distinguished by the darker body color, the presence of black stiff bristles on the mesosoma, the projection of the anteromedial portion of T1 in the male (very similar to the horn in the female), and the presence of notauli.
Etymology. The specific epithet robusta refers to the body shape.
