Remarks

• Systematics: Slide-mounted adult female with: enlarged setae conical, curved, sides slightly concave, apices acute, setae of 2 sizes, large size forming 3 longitudinal lines on each side of abdomen, small size scattered over dorsum; microtubular ducts short, with 2 sclerotized areas (personal observation). This species is similar to A. venezuelaensis (Foldi & Kozár, 2007), but differs by shorter tibia than tarsus, larger sizes of legs and antennae, and by absence of spinulae on first legs. (Kozár & Konczné Benedicty, 2008)
• Structure: Body elongate oval, 3.108 (1.994-3.108) mm long and 1.735 (1.217-1.735) wide. Antenna 7 segmented. there is one sensory pore on the 2nd segment and the 3rd segment is almost parallel sided. On apical segment tree sensory falcate setae. On the two preapical segments, long falcate sensory setae present. the segments of the antenna are covered with few hairlike setae. Frontal lobe present. Eye visible, located on venter. Venter: Labium two segmented. Basal segment with two pairs of setae. Stylet loop reaches behind median coxae. Legs long. median and posterior coxae with spinulae, posterior coxae with small number of big translucent pores in groups. Trochanger with two pores on each side. Claw with dentible. Legs with few hairlike setae. Venter with a small number of scattered, hair-like setae, of two sizes. In submarginal band few setose hair-like setae present. microtubular duct absent. Macrotubular ducts of two sizes. Cruciform pores numerous in a submarginal band. Dorsum: Dorsal setae spine-like, 3-4 times longer than wide, of different sizes found in groups of 2-3 spines on abdominal margin. One the middorsum setae about the same size, in bands. On the penultimate three segments, in midline, spines are the same size as elsewhere. Macrotubular ducts present in small number on all segments. Microtubular ducts with simple oval opening scattered among dorsal setae, one present on the base of some spines. Disc pores absent. Anal lobes long, as long as wide, bith three equal long spine-like setae. Anal lobes slightly sclerotized. Suranal setae hair-like. On penultimate segments, before anal ring, sclerotized plate absent. (Kozár & Konczné Benedicty, 2008)
