Archaeoteleia robusta Masner , new species

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 T 1 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.
