Remarks

• Systematics: This species is similar to A. adenostonae(Ehrhorn, 1898), but the latter has no cruciform pores and the structure of microtubular ducts is different. There are some similarities with A. arenariae Miller and Miller, 1993, but this species has longer spines on dorsum and the groups of spines on ventral submargin not developed, antennae six segmented, and the microtubular ducts are short. The A. microtrichus Miller & Miller, 1993, is different by shorter spines on dorsum and sex segmented antennae.
• Structure: Adult female: Body elongate oval, 2.435 (1.968-2.435) mm long and 1.450 (1.114-1.450) wide. Antenna 7 segmented. There is one sensory pore on the 2nd segment of the antenna and 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 teh antenna are covered with few hairlike setae. Both frontal lobe and frontal tubercles present. Eye situated on venter. Venter: Labium two-segmented. Basal segment with two pairs of setae. Legs long, claw digitules slightly knobbed. All coxae with spinulae, posterior coxae with hight number of small translucent pores. Trochanter with two pores on each side. Legs with few hairlike setae and with one sensory pore on tarsus. Dixc pores 5 locular, distributed in rare bands on all segments of abdomen and thorax. Venter with a small number of scattered ahir-like setae, of two sizes. in submarginal band spine-like setae in groups of 2-10. Microtubular duct present only on the margin. Macrotubular ducts of two sizes, in small number on all segments. Cruciform pores present in small number in a submarginal band. Dorsum: Dorsal setae spine-like, very strong, ide, 1-2 times longer than wide, of different sizes, found in one row on abdominal margin. One the abdominal margin 2-3 setae present on each segment. On the middorsum, setae about the same size in a rare ro. Macrotubular ducts present in small number on all segments. Microtubular ducts with bifurcated opening scattered among dorsal setae, one present on the base of spines. Disc pores absent. Anal lobes long with two short spine-like setae along inner margin. Anal lobes sclerotized. suranal setae hair-like. On penultimate segments, before the anal ring, a sclerotized plate absent.
