Remarks

• Systematics: Lambdin (1983) agrees with Borchsenius (1960d) that this species is most closely related to A. schimae.
• Structure: Test of the adult female is barnacle shaped, with several white bands which radiate from the cone. Subtransparent brownish red in color, the posterior end bears a tube like projection. Adult female is strongly chitinized and ends with two prominent lobes. Larva is elliptical and distinctly segmented (Kuwana, 1907). This species was redescribed by Lambdin (1983). Hodgson & Williams (2016) added the following details to his description: (i) the anteroventral sclerotizations on the anal lobes are absent; (ii) the structure of the multilocular disc-pores looks normal (Lambdin illustrates two rings of loculi); (iii) the anterior line of multilocular disc-pores is medial on the metathorax and these pores have fewer loculi; (iv) Lambdin describes the 8-shaped pores on the dorsum of the cephalothorax as being in transverse lines but they appeared to be randomly distributed to us; (v) the transverse bands of 8-shaped pores dorsally on the abdomen appear to be in three bands as follows: a broad band on segment III or IV (but Borchsenius (1960) shows this as two bands), possibly no band on IV or V, but narrow bands on VI and VII; (vi) the larger tubular ducts appear to be on segment VI, and (vii) each transverse band of multilocular disc-pores has a gap between the submarginal group and the medial band.
• General Remarks: Detailed redescription and illustration by Lambdin (1983).
