Archiborborus (Procopromyza) annulatus Richards 1963: 232 View in CoL

Description. Head yellow, upper occiput and posterior frons orange to brown, covered with microtomentum except shiny stripes on interfrontal plates outlining frontal triangle. Distance from ocellar bristles to medial ocellus equal to distance between ocelli, ocellar bristles reclinate-divergent. Anterior genal bristle about 0.6X length of vibrissa, no strong subvibrissal bristle.

Thorax reddish-brown to dark brown, lateral margins of scutum and pleural sclerites may be mottled with yellow, entirely covered with microtomentum. Scutum with paler dorsocentral stripes, yellow to reddish-brown. Halter whitish, brown at base of knob.

Legs yellowish brown to dark brown. Male fore basotarsomere with a small apical spur. Femora 1–3 with a yellow band at two-thirds, otherwise reddish brown to dark brown. Tibia 2 with row of anterodorsal, 1 anteroventral, 1 posteroventral, 4 subapical bristles. Tibia 3 with strong anteroventral, 3 ventroapical bristles.

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

Abdomen with tergites brown to dark brown, strongly sclerotized, covered with microtomentum. Sternites moderately sclerotized. Tergites 3–5 with a strong bristle in posterolateral corners.

Male postabdomen: Sternite 5 with lateral margins rounded, converging, posterior margin with a pair of thin, incurved lobes, anterior apodeme short and broad ( Fig. 23 View FIGURES 21–24 ). Surstylus very broad, posterior edges nearly meeting medially ( Fig. 22 View FIGURES 21–24 ). Pregonite distinct, relatively large. Postgonite with lobes widely separated, anterior lobe curved anteriorly, long, rounded, posterior lobe pointed. Basiphallus with broad, very short epiphallus, short, narrow preepiphallus. Ejaculatory apodeme somewhat enlarged. Distiphallus simple, with a smooth, weakly curved dorsal tube ( Fig. 21 View FIGURES 21–24 ).

Female postabdomen: Tergites 6–7 and sternites 6–7 moderately sclerotized, slightly wider than long, entirely covered with microtomentum. Tergites with 3 posterior strips, sternites with 2 posterior strips. Tergite 8 slightly narrower posteriorly, anterior margin shallowly emarginated, posterior two-thirds covered with microtomentum. Epiproct broad, with long anterior arms, posterior portion covered with microtomentum, with 1 pair of setae. Cerci narrow. Sclerites of sternite 8 subrectangular, distal half covered with microtomentum. Hypoproct subrectangular, anterior margin notched, edge lateral to notch shiny. Spermathecae barrel-shaped, about 1.5X longer than wide, with basal and apical invaginations, sclerotized duct short.

Comments. A. annutalus is quite distinctive within the genus, particularly the banded legs and striped scutum. Only A. vittatus sp. nov. is likely to be confused with this species, but is readily distinguished by the colour of the femora and the leg chaetotaxy.
