(Figs 1, 5, 9, 10, 17)
Eotilla mickeli Schuster, 1949: 77 –80; holotype ♂, Chile: Valparaíso, Olmué [32°59'45"S 71°11'29"W] (Museum of Comparative Zoology, Cambridge, Massachusetts, USA), not examined.
Diagnosis. Male. Head, mesosoma and metasoma dark brown to black (Figs 1, 5). T1, T2 and S2 with a few scalelike setae only on posterior margin or without (Figs 9, 10). T7 convex, without any inverted-V-shaped depression. Posteriormost terga and sterna with dark, short and coarse setae (Figs 9, 10). Female. Unknown.
Redescription. Male. Length 4.4–5.6 mm. General body color black. Antenna, legs and basal part of mandible dark brown, rest of mandible lighter than basal part (Figs 1, 5, 17).
Head oval, 1.1–1.2 × as broad as high and 1.3–1.5 × as broad as mesosoma, with dense scale-like setae covering frons from base of mandible to slightly below eye height, scattered scale-like setae reaching top of eye and behind head; vertex with a few scattered scale-like setae; gena covered or with scattered scale-like setae; plumose setae long, dark and scattered over vertex and frons; vertex with spaced punctation (Fig. 17). POL 1.0–1.5 × as long as OOL, POL 1.7–2.3 × as long as LOL; eyes ovoid, separated by 0.9–1.0 × their height, malar space 0.03–0.06 × eye height. Scape with scale-like and scattered dark plumose setae, except ventrally glabrous; scape 1.8–2.1 × as long as broad and 2.0–2.6 × as long as pedicel; flagellomeres cylindrical, F1 0.7–0.9 × length of scape and 0.7–0.8 × length of F2, F2–F6 approximately same length, F7–F10 gradually decreasing in length, F11 elongated with rounded apex.
Mesosoma elongate, 1.6–2.1 × as long as broad; punctation well marked, slightly contiguous on dorsum and more spaced on pleura and vertical surface of propodeum. Pronotum transverse, anteriorly forming a collar with white and long plumose setae, rest covered almost completely with scale-like and white plumose setae, plumose setae dark on dorsum. Mesonotum moderately punctate; with scattered scale-like and dark plumose setae, scalelike setae denser on posterior margin; tegula convex, smooth and basal half covered with scale-like setae; scutellum with scattered scale-like and dark plumose setae. Metanotum transverse, narrow, with scattered scale-like and a few dark plumose setae. Propodeum with contiguous punctation; with small dark plumose setae dorsally; vertical surface with scattered long white plumose setae, except central part smooth and without setae; rest of propodeum covered with scale-like and white plumose setae; a group of scale-like setae at insertion of hind coxa. Propleuron covered with plumose setae; mesopleuron convex, punctate except smooth anterodorsal to mid coxa, almost covered by scale-like and white plumose setae, but less dense medially and above mid coxa exposing the cuticle; metapleuron with spaced punctation, metepisternum with scattered long plumose setae and with scale-like setae above insertion of metacoxa, metepimeron covered with scale-like setae on upper half.
Fore wing 2.8–3.1 × as long as broad, densely setose, hyaline, except a narrow small spot posterior to marginal cell; venation light brown, with coarse dark plumose setae.
Legs slender; anterior surface of coxae, trochanters and femora almost covered by scale-like setae; plumose setae scattered across surfaces of legs, becoming denser where no scale-like setae; mid and hind tibial spurs white.
Metasoma 2.4–2.6 × as long as broad, T1 1.2–1.7 × as long as wide and 0.6 × as wide as T2 (Fig. 9); terga with well-marked and contiguous punctation. T1 covered with erect white plumose setae and scattered dark plumose setae on dorsum, without or with a few scattered scale-like setae on central area, and dense scale-like setae along posterior margin; T2 entirely covered with erect dark plumose setae and decumbent dark simple setae and scattered white plumose setae on sides, dense scale-like setae along posterior margin; dark felt line 0.28–0.52 × lateral length of T2, its anterior extremity at 0.21–0.31 × lateral length of T2; T3–T5 with erect dark plumose setae and decumbent dark simple setae, scale-like setae on posterior margins; T6 with oblique dark brown coarse plumose setae without scale-like setae; T7 without a depression, and covered with dark brown coarse plumose setae, shorter than T6; sterna with sculpture and distribution of setae similar to corresponding terga, except erect plumose setae white (but becoming dark on posteriormost sterna), S1 without scale-like setae, S6 with scale-like setae on posterior margin (Fig. 10).
Variation. The number of scale-like setae is variable, but the setation pattern is consistent.
Discussion. Schuster (1949) based his description on seven males from Chile, and Mickel (1968) described the female based in a (misidentified) specimen from Argentina. There are many differences between species from Argentina and Chile, and it would be wrong to think that those are conspecific. We believe that Mickel’s female corresponds to a new species (E. schusteri) described below.
Distribution. Chile: Atacama, Biobío, Copiapó, Coquimbo, Quillota, Maule, Santiago, Valparaíso (Fig. 38).
Phenology. September–February.
