Archaeoteleia penai Masner , new species

Figures 50–53

Description: Female. Length 2.9–2.95 mm. Color: generally ochraceous; antennal clava almost black; legs, A1–A5, lower frons, side of pronotum, most of mesopleuron, legs including coxae, yellowish; propodeum and tip of horn on T1 dark brown.

Head ( Figs. 51–53 ): vertex, occiput, entire frons, upper gena rugose punctate with fine, appressed pilosity; eye glabrous; LOL greater than OOL, ocellar triangle broad; occipital carina well-developed, moderately foveolate medially, weakly so at sides, complete; central keel very short, delicate; facial striae fine, dense, reaching inner orbits; clypeus slightly higher than wide, predominantly smooth, anterolateral corners weakly projecting; rim of torulus confluent with dorsal margin of clypeus; A1 5.2 times as long as wide; A2 3.2 times as long as wide; A3 3.7 times as long as A2; flagellum with fairly short setae; claval formula A6–A12/2-2-2- 2-2-2-1.

Mesosoma ( Figs. 52–53 ): transverse pronotal carina sharp, gently arcuate, anterolateral corners angular, but not spikelike raised; vertical epomial carina absent or only a rudiment present dorsally; horizontal epomial carina sharp, pronotal shoulders relatively broad, deeply punctate; lateral pronotum almost entirely sculptured, punctured; netrion well developed, with fine appressed pilosity, densely punctured; mesonotum moderately convex, almost glabrous, with only few short appressed setae, evenly and densely thimblelike punctured; admedian lines present, very short; notaulus complete, deeply incised; parapsidal line absent; transscutal articulation distinct, margined posteriorly by foveolae; scutellum transverse, length 0.5 times length of mesoscutum, densely punctate, setose; scutellar spines sharp, slightly shorter than scutellar disk, pointed, directed posteriorly; mesopleural carina absent; mesopleuron entirely sculptured, without smooth areas, mesepimeron, mesepisternum with subhorizontal dense rugulae; acetabular carina fine, crenulate; posterior margin of mesopleuron with chain of foveolae extending ventrally to mid coxal cavity; lower half of metapleuron densely punctured, upper portion with small smooth area, entire metapleuron only sparsely hairy; propodeum rugose punctate, with shallow medial excavation, finely punctured; median keels fine, complete; fore wing widely surpassing apex of metasoma, almost clear, without cloud of pigmentation below stigma; M, basal vein well indicated; Cu, M, Rs vaguely infuscate; marginal vein very thick, subtriangular, markedly darkened; postmarginal vein completely absent; stigmal vein forming 45 angle, not hooked apically, very weakly arched; legs long and slender; inner surface of hind coxa with strong diagonal striae.

Metasoma ( Figs. 50, 53 ) relatively short; length 3.2 times width; T1 relatively short, length 0.7 times width, with only slight smooth horn anteromedially, in lateral view horn not exceeding upper margin of propodeum, T1 otherwise longitudinally costate; length of T2 0.5 times width; length of T3 0.5 times width; length of T4 0.5 times width; T2–T4 longitudinally costate; length of T5 0.6 times width; length of T6 equal to width; T5–T6 predominantly punctured.

Male unknown.

Diagnosis. Closest to A. mellea and A. puncticeps , but distinguished by its small, gracile body and the relatively long and slender appendages. The length of T6 is equal to its width, and the horn on T1 is relatively weakly developed, not surpassing the upper margin of the propodeum. The most salient combination of features to separate A. penai from all other species is the thimblelike sculpture of the mesonotum, entirely sculptured mesopleuron, small hump on T1, and the short, nipplelike T6.

Etymology. Named in memory of Luís E. Peña, distinguished Chilean entomologist and naturalist, and the collector of both specimens.
