Claws (c) of a characteristic shape, quite long and narrow, slightly longer than width of tarsi, almost straight with a minute denticle; length: III: 33–37 μm; claw digitules (cdt) distinctly longer than claw, with minute apical knobs.

Abdomen: quite long; tergites (at) apparently absent; sternites (as) present on all segments; pleurites all membranous. Caudal extensions (ce) of segment VII absent. Setae all hs, segment I–VII each with 4–6 dorsal abdominal setae (ads) and generally 3 dorsal pleural setae (dpls); also each segment generally with with 4 ventral abdominal setae (avs), and 1 or 2 ventral pleural setae (vpls).

Segment VIII: tergite (at) unsclerotised but sternite sclerotised. Caudal extension present, small, positioned about 1/2–2/3rds along side of segment, each with 3 or 4 long pleural setae, longest 50–60 μm long. Glandular pouches (gp) cone-shaped; each with 2 glandular pouch setae (gps), each 95–132 μm long with non-flagellate apices.

Genital segments: penial sheath (ps) divided into a bulbous segment IX and a longer, sharply pointed style. Length of segment IX 80–85 μm, width 80–105 μm; anal opening near posterior margin of segment IX, width 28–33 μm; with 8 hs setae on each margin + ventral surface. Style 165–185 μm long, 50–58 μm wide at base; with a pair of long hs about 1/2 way along length, each 40–45 μm long; other setae absent; apex with a few small sensilla.Aedeagus (aed) quite long, broad anteriorly (26–28 μm wide), tapering to a narrow apex; length 190–200 μm. Basal rod (bra) more or less absent.

Comment. A. rosaeformis   belongs to Group II that lack well-developed caudal extentions on abdominal segment VIII, although there are suggestions of small bumps on each side of this segment. It differs from other other two species in this group ( A. pharetrata   and A. spinifer   ) in having: (i) no prescutal setae; (ii) long, rather narrow claws.
