(Figs. 39, 44, 203)  
 Description. Head black, face and prementum dark reddish brown, antenna and maxillary palp orange. Mostly covered with microtomentum, face with a ventromedial shiny spot. Ocellar bristles about 1 ocellus width anterior to median ocellus. Subvibrissal bristle about 0.3X length of vibrissa, anterior genal bristle about 0.5X length of vibrissa. Gena height about 0.8X eye height.   
Thorax black, mostly covered with microtomentum. Proepisternum shiny, anepisternum with a subrectangular shiny spot on ventral half extending from just posterior to anterior margin to posterior quarter of sclerite, katepisternum with a small shiny spot behind fore coxa. Dorsocentral bristles very short in male, barely distinguishable from surrounding setae, longer and clearly distinguishable in female. Halter mostly pale brown, tip of knob white.  
Legs black, trochanters, joints, and tarsi reddish brown. Fore basotarsomere with a short spur in male. Mid tibia with rows of anterodorsal and posterodorsal bristles, 1 anteroventral, 1 posteroventral, 4 subapical bristles. Hind tibia with 1 anteroventral, 3 ventroapical bristles.  
Wing yellowish brown.  
Abdominal tergites black, heavily sclerotized, covered with microtomentum in both sexes. Sternites black, heavily sclerotized in male, moderately sclerotized in female, covered with microtomentum in both sexes. Sternites slightly wider than long in male, longer than wide in females.  
Male postabdomen: Sternite 5 with curved lateral margins, widest at about two-thirds length, anterior apodeme broad, about as long as external portion (Fig. 44). Surstylus scooped, with wavy margins. Pregonite small, distinct. Postgonite with lobes well separated, anterior lobe rounded, posterior lobe somewhat pointed. Basiphallus with very short epiphallus, long narrow preepiphallus. Distiphallus with curved spinose dorsal tube flanked by one spike-like sclerite, ventral sacs fairly well developed, covered with small spinules (Fig. 39).  
Female postabdomen: Tergites 6–7 wider than long, margins sclerotized, covered with microtomentum. Sternite 6 entirely sclerotized, sternite 7 with a medial unsclerotized spot, both covered with microtomentum. Tergites with 3 posterior strips, sternites with 2 posterior strips. Tergite 8 longer than wide, anterior margin emarginated, distal two-thirds covered with microtomentum. Epiproct with long anterior arms, distal portion covered with microtomentum, with 2 pairs of setae. Cerci long. Sclerites of sternite 8 narrow, anterior end pointed, pinched medially, anterior quarter shiny. Hypoproct subrectangular, with a curved unsclerotized band medially, covered with microtomentum except anterior margin. Spermathecae barrel-shaped, about 1.3X longer than wide, without invaginations, sclerotized ducts about as long as spermathecae.

 Comments. The species name is from the Latin fuliginosus (sooty) referring to the dark, pollinose appearance of this species. This appearance separates this species from most others; A. bucki is similar but is brachypterous and has a smaller shiny spot on the anepisternum.
