Remarks

• Systematics: This species is similar to A. perplexus (Hempel, 1900), but differs by longer spines on dorsal margin and middorsum, greater number of marginal spines, by equal sizes of tibia and tarsus, and expecially by presence of three pair of small microspines in middorsum on three penultimate dorsal segments. It differs from A. venezuelaensis (Foldi & Kozár, 2007) by the presence of three pair of small microspines in middorsum on three penultimate dorsal segments, by longer spines on dorsum, larger sized of legs and antennae, and by absence of spinulae on first legs. (Kozár & Konczné Benedicty, 2008) A. lanatus differs from A. microspinus, in having (character-states of A. microspinus in brackets taken from Kozár and Konczné Benedicty, 2008): i) dorsal microtubular ducts very abundant throughout (scattered among dorsal surface, one present on the base of spines), ii) metacoxae with 40–50 translucent pores (small number of pores), iii); middorsal setae on midline of the three penultimate segments about the same size as others on dorsum (setae very short), and iv) frontal lobes absent (present). (Gonzalez, et al., 2020)
• Structure: Body elongate oval, 2.616 (2.124-3.497) mm long and 1.709 (1.450-1.709) wide. Antenna 7 segmented. There is one sensory pore on the 2nd segment of the antenna. The 3rd segment is almost parallel sided. On apical segment three sensory falcate setae are found. On the two preapical segments, falcate sensory setae are present. The segments of the antenna are covered with few hairlike setae. Frontal lobe present. eye visible, situated on venter. Venter: Labium two-segmented. Basal segment with two pairs of setae. Stylet loop reaches behine median coxae. Legs long. All coxae with spinulae, posterior coxae, with small number of big translucent pores. Trochanter with two pores on each side. Claw with denticle. Legs with few hairlike setae and with one sensory pore on tarsus. disc pores 3-, and 4-locular, distributed in rare bands on all segments of abdomen and thorax. Venter with a small number of scattered, hair-like setae, of two sizes. in submarginal band setose hair-like setae present in groups of 2-10 setae. Microtubular duct present only on the margin. Macrotubular ducts of two sizes present in a small number on all segements. Cruciform pores numberous in a submarginal band. Dorsum: dorsal setae spine-like, very strong, wide, 5-6 times longer than wide, of different sizes found in groups of 3-5 spines on abdominal margin. On the middorsum setae about the same size in bands. On the penultimate three segments, long spines present. Macrotubular ducts present in small number on all segments. Microtubular ducts, with simple opening, scattered among dorsal setae, on present on the base of spines. Disc pores absent. Anal lobes long, as long as wide, with three equal long spine-like setae. Anal lobes sclerotized. Suranal setae hair-like. On penultimate segments, before the anal ring, sclerotized plate absent. (Kozár & Konczné Benedicty, 2008)
