( Figs. 9 View FIGURES 7–12 , 15 View FIGURES 13–18 , 130–132 View FIGURES 125–134 , 221 View FIGURES 213–221 )
Description. As described for A. nitidicollis . Microtomentum on occiput reaching dorsally to bases of postocellar bristles. Lateral and posterior margins of scutum, margins of scutellum, latero- and mediotergite, meron and metapleuron covered with microtomentum, rest of thorax shiny. Presutural acrostichal setae in 4 rows. Microtrichia not reduced at base of wing. Abdominal tergites 4–5 with microtomentum on basal third, shiny laterally.
Male postabdomen: Sternite 5 as described for the species group. Surstylus with anterior margin raised as a broad smooth ridge, anteroventral corner nearly right-angled, rounded, ventral tooth broad, pointed apically ( Fig. 131 View FIGURES 125–134 ). Pregonite indistinct, fully fused with postgonite. Postgonite with lobes barely separated, anterior lobe short, narrow, quadrate, posterior lobe pointed, long. Basiphallus narrow, with long epiphallus and preepiphallus. Distiphallus with narrow, rounded, spinose dorsal knob ( Fig. 130 View FIGURES 125–134 ).
Female postabdomen: Tergites 6–7 and sternites 6–7 wider than long, moderately sclerotized, covered with microtomentum. Tergites with 3 posterior strips, sternites with 2 posterior strips. Tergite 8 shiny, widest anteriorly, pinched medially, shallowly emarginated anteriorly and posteriorly, anterior corners nearly meeting sternite 8 laterally. Epiproct with short, broad anterior arms, with 2 pairs of setae and a medial unpaired seta ( Fig. 132 View FIGURES 125–134 ). Cerci narrow. Sclerites of sternite 8 narrow, pinched medially, distal third broader and covered with microtomentum, apices pointed. Hypoproct depressed antero-medially ( Fig. 133 View FIGURES 125–134 ). Spermathecae round, long apical invagination meeting basal invagination, sclerotized duct short ( Fig. 134 View FIGURES 125–134 ).

Comments. The species name is derived from the Greek tetra (four) and stichos (row), referring to the four rows of acrostichal setae. This character distinguishes this and the very similar A. unduavi sp. nov. from the nitidicollis complex.
