Frutillaria transversa View in CoL sp. n.

( Figs. 50–52 View FIGURES 47 – 52 , 90, 91, 94 View FIGURES 86 – 94 , 115 View FIGURES 108 – 115 )

Description. Length 1.7–2.3 mm (head + thorax 0.8–1.0 mm)

Occiput black, face orange, gena and frons intermediately coloured. Frons with shiny spots lateral to ocellar triangle. Antennae orange. Clypeus mostly orange, prementum dark brown.

Thorax black, postalar callus occasionally reddish, wing rudiment brown. Mesoscutum and scutellum entirely covered with microtomentum. Anepisternum mostly shiny, anterior and posterior margins and part of dorsal margin with microtomentum. Katepisternum with a shiny spot behind coxa, not extending toward bristle; posterior part of katepisternum, 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, joints narrowly orange, tarsi and trochanters orange, fore coxa black; fore femur shiny or very sparsely microtomentose posteriorly. Mid femur with 2 anterior bristles.

Male abdomen ( Figs. 50–52 View FIGURES 47 – 52 ): Tergites 1–5 mostly covered in microtomentum, shiny along margins. Sternites 1–5 shiny. Surstylus with a broad basal part and a thin inner arm, outer corner sharply angular, with a ridge running between outer corner to tip of inner arm; in posterior view, inner arm forms a continuous curve with lateral edge of surstylus, projecting medially. Postgonite bilobed, both lobes long and thin. Epiphallus and preepiphallus welldeveloped, epiphallus laterally broadened at tip. Distiphallus with central projecting sclerite very wide in dorsal view, projecting well beyond lateral arms, complex and with multiple fringes and projections. Lateral arms slightly narrower apically, upturned at tip, with a distinct curved projection below lateral arms.

Female abdomen ( Figs. 90, 91, 94 View FIGURES 86 – 94 ): Syntergite 1+2 with irregular patches of microtomentum, tergites 3–6 mostly covered with microtomentum. Sternites 2–3 mostly shiny, sternite 4 with a medial patch of microtomentum, sternites 5–6 mostly covered with microtomentum, margins shiny. Tergites 7 and 8 and sternite 7 mostly shiny with some microtomentum along posterior margin. Tergite 8 complete, with about 8 setae along posterior margin, epiproct triangular with distinct anterior arms. Sclerites of sternite 8 strongly sclerotized, teardrop-shaped. Hypoproct strongly sclerotized, U-shaped with arms anterior. Spermathecae with basal invagination consisting of a basal sheath of several rings and apical rounded cap; no apical invagination, but variably pointed apically.
