Remarks. According to the morphological characters and morphometric data given in the original description (Sher 1973), there is no difference between the Iranian population of A. belli and the original description. A. belli is morphologically similar to A. homoglans Siddiqi Khan & Reddy 1991, but it differs by having three annuli usually in the cephalic region as compared with usually two annuli in the latter, a longer stylet (16.2–18 vs 14–15 µm) with a longer distance between stylet and dorsal gland orifice (4–6 vs 3–3.5 µm), and asymmetrical subventral oesophageal glands in size and location (symmetrical in A. homoglans). It also differs from A. joenssoni Ryss et al. 2005 in having a smooth tail tip (vs crenate), rounded to elongated spermatheca (vs rounded axial chamber with offset pouch), smaller tail (c= 19.4–26.9 vs 13.7–14.9) and length of dorsal gland lobe about two corresponding body diameters (vs one corresponding body diameter or less).
