( Figs. 64 View FIGURES 61–64 , 206 View FIGURES 204–212 )

Description. Head yellow, covered with microtomentum except shiny stripes on interfrontal plates outlining frontal triangle. Ocellar bristles about one ocellus width anterior to medial ocellus. One enlarged subvibrissal bristle, about 0.5X length of vibrissa, anterior genal bristle about 0.6X length of vibrissa.

Thorax reddish brown mottled with yellow at edges of scutum and on pleural sclerites, entirely covered with microtomentum. Scutum with distinct yellow dorsocentral stripes. Halter whitish, brown at base of knob.

Legs yellow, with thin brown band at apex of femur 3, tarsus 3 brown. Tibia 2 with anterodorsal and posterodorsal rows, 1 anteroventral, 1 posteroventral, and ring of 4 subapical bristles. Tibia 3 with anterodorsal and posterodorsal rows and 2 ventroapical bristles.

Wing brown, with white spots on crossveins r-m and dm-cu and on vein R 4+5 distal to r-m.

Abdomen with tergites brown and strongly sclerotized, covered with microtomentum, sternites weakly sclerotized. Tergites 3–5 with a strong bristle in posterolateral corners.

Male postabdomen: Sternite 5 simple, rectangular. Surstylus long, narrow. Postgonite with lobes moderately separated, anterior lobe rounded, posterior lobe pointed. No distinct pregonite. Basiphallus with broad and short epiphallus and preepiphallus. Distiphallus small, with smooth dorsal tube flanked by a long spine-like sclerite, distal ventral sclerite subtriangular, separated from other sclerites by unsclerotized membrane ( Fig. 64 View FIGURES 61–64 ).

Female postabdomen: Sternites 6–7 and tergites 6–7 rectangular, weakly sclerotized, no posterior strips. Tergite 8 with microtomentum posteromedially. Epiproct with parallel sides, pointed posteriorly, short anterior arms, 2 setae. Cerci normal. Sclerites of sternite 8 teardrop-shaped, mostly shiny with microtomentum along rounded posterior margin. Hypoproct subrectangular, covered with microtomentum. Spermathecae not observed (specimen not dissected).

Type material. Holotype ♂: CHILE: Biobío: Laraquete , 37°10’S 73°10’W, yellow pans, 10–25 Jan 1993, P. Salinas, debu01033618 ( MNNC) GoogleMaps . Paratypes: Biobío: Arauco, Contulmo Playa , 10–25 Jan 1993, P. Salinas (1 ♀, CNCI) ; Ñuble, Alto Tregualemu , ca. 20 km SE Chovellen, 500 m, 26–27 Jan 1979, D. & M. Davis & B. Akerbergs (1 ♂, USNM) ; Valparaíso: Zapallar , Quebrada el Tigre, upper trail, 32°33.67'S 71°26.70'W, 250 m, 9 Dec 2008, J.H. Kits & S.A. Marshall (1 ♀, DEBU) GoogleMaps .

Comments. The species name refers to the stripes on the scutum. Despite the large number of archiborborine specimens from Chile that were examined, only four specimens of this species were located. Although superficially similar to A. annulatus , it does not appear to be closely related to that species, and its relationships within the genus are unclear.
