Frutillaria n. sp. A

Description. Length: 1.8 mm (head + thorax 0.9 mm)

Head entirely reddish brown, slightly darker on occiput. Frons with shiny spots lateral to ocellar triangle. Thorax black, postalar callus and apex of scutellum reddish, wing rudiment dark brown. Mesoscutum with some microtomentum anteriorly, bare posteriorly, disc of scutellum bare laterally with a medial band of microtomentum. Anepisternum mostly shiny, posterior and dorsal margin with microtomentum. Katepisternum with a shiny spot behind coxa, not extending toward bristle; posterior part below bristle, meron and metapleuron shiny with exception of a stripe of microtomentum between posterior thoracic spiracle and base of hind coxa. Laterotergite mostly shiny.

Legs black, fore coxa dark reddish brown, trochanters, joints, and tarsi orange. Fore femur mostly shiny posteriorly. Mid femur with 2 anterior bristles.

Male unknown.

Female abdomen ( Figs. 97, 98, 102 ): Tergites 1–5 with some microtomentum basally, mostly shiny apically, tergites 6–7 covered with microtomentum on apical half, tergite 8 shiny with some microtomentum along apical margin. Sternites 2–4 shiny, sternite 5 with some scattered microtomentum, sternite 6 covered with microtomentum on apical half, sternite 7 mostly shiny with microtomentum on apical 1/3. Tergite 8 complete, epiproct long with short anterior arms, parallel-sided between arms and base of cerci. Sclerites of sternite 8 sub-rectangular, hypoproct with a U-shaped sclerite. Spermathecae with basal invagination long, mushroom-shaped, annulated; no apical invagination, but variably pointed apically.

Material examined. CHILE: Araucanía: Conguillo Natl. Pk., nr. Vista Hermosa, 38°45’8”S 71°37’24”W, 816 m, forest edge, yellow pans, 22–24 Feb 2005, [L. Masner] (2 Ƥ, DEBU).

Comments. This species shares the extensively shiny mesoscutum with F. glabra , but is clearly distinct from that species based on external and internal characters.
