(Figs. 2–6, 59, 60, 65, 108)
Description. Length 1.5–1.9 mm (head + thorax 0.8–1.0 mm)
Occiput brown, face and gena yellow, frons intermediately coloured. Frons with shiny spots lateral to ocellar triangle. Antenna yellow. Clypeus and prementum yellow.
view, (9) phallus and postgonite, lateral view.
Thorax black, postalar callus and scutellum reddish. Wing rudiment brown. Mesoscutum and scutellum extensively shiny, some microtomentum near margins. Anepisternum entirely shiny. Katepisternum with a large shiny patch behind fore coxa extending posteriorly as a triangle to near bristle, narrowly separated from posterior shiny patch by a band of microtomentum. Meron and metapleuron shiny with the exception of a strip of microtomentum between posterior thoracic spiracle and base of hind coxa. Laterotergite mostly shiny.
Legs dark brown, fore coxa, fore femur, trochanters, diffuse area near joints, and tarsi yellow. Mid femur with 2 anterior bristles, mid tibia without posteroventral bristle.
Male abdomen (Figs. 3–6): Syntergite 1+2 with some microtomentum in a patch behind scutellum, tergites 3– 5 entirely shiny. Sternites 2–5 entirely shiny. Surstylus with broad basal section and fairly long inner arm, outer corner rounded, not produced. Postgonite bilobed, anterior lobe about ½ length of posterior. Epiphallus barely produced, broadened laterally; preepipallus well-developed, long and thin. Distiphallus with lateral arm produced from ventral sclerite, pointed apically with 2 medial teeth; a large complex, translucent sclerite apically of uncertain homology; ventral sacs clear, not projecting and barely visible.
Female abdomen (Figs. 59, 60, 65): Syntergite 1+2 with a patch of microtomentum behind scutellum, tergites 3–5 with a band of microtomentum near base. Tergite 6 covered with microtomentum, tergites 7–8 mostly shiny with very little microtomentum apically. Sternites 2–5 shiny, sternite 6 covered with microtomentum, tergite 7 mostly shiny with some microtomentum apically. Tergite 8 complete, epiproct broadly triangular with distinct anterior arms. Sclerites of sternite 8 teardrop-shaped, hypoproct not sclerotized. Spermathecae with basal invagination short, annulated; apical invagination short, subconical, smooth
Type material. Holotype 3: CHILE: Maule: Putú, ~ 15 km N Constitución, along stream, 26 Nov 2006, S.A. Marshall (MNNC). Paratypes: same data as holotype (2 3, 8 Ƥ, DEBU).
Comments. This species was found in a small wooded ravine on the heavily agricultural coastal plain north of Constitución. The habitat patch was extremely small and completely isolated by a large area of pasture from any other intact forest; it was apparently preserved only by virtue of the steep sides which prevented cattle from entering to browse. The species name refers to the hidden and unexpected collection locality.
