Male: D, abdomen (dorsal); E, abdomen (lateral); F, P5. Nota female: - Body slender. - last thoracic somite rounnded, with a row of 4 to 5 small teeth (as in A. clausi). - Proportion of thorax to abdomen (included furca) 84 : 24. - Abdomen 3-segmented. - Genital somite (= double-somite) longer than somites 2 and 3 combined, and as wide as long. This double-somite has a few small lateral hairs, but there are no dorsal spines on this or succeeding somites. Rostral filaments present, very slender. - A1 reaches to end of 2nd abdominal somite. - P5P5 basal segment short and broad; length 16, breadth 12. Terminal spine rather stout and curved, smooth. Nota male: - Abdomen and thorax 58 : 110. - last thoracic somite rounded and with teeth as in female. - Abdomen 5-segmented - 1st abdominal somite with lateral hairs. - Abdominal somites 2, 3, 4 with posterior row of very minute denticles, dorsally. - Furcal rami [= caudal rami] short and broad, with inner hairs. - A1 reaches nearly to end of thorax. - Right P5: exopod with a process on posterior side bearing a slender seta; 2nd exopodal segment produced into a large inner lobe. 2nd exopodal segment of left leg with a stout terminal spine and a curved anterior seta. For Gurney, this species very closely resembles A. bifilosa, from which it is separated only by some minute details.

According to Nishida (1985, p.36) the Pacific distribution of this species and A. hamata supports the opinion of Grice (1964) that these two species may be conspecific.
Any confusion appears in the literature between A. hamata, A. fossae and A. bispinosa.
