Diagnosis

A1 of female 10- to 17-segmented, without hyaline membrane or spinule row on distal segments. Rami of P1-4 3-segmented inmost cases, sometimes with P1Ri, P2Ri and P1Re 2-segmented. P4Ri3 with 2 terminal spines. P5 usually 2-segmented, rarely with proximal segment partially fused with 1st urosomal somite (complete fusion seen sometimes in A. nanus and A. abyssicola only); proximal segment with seta at outer corner; distal segment with long apical outer seta and shorter inner spine, latter usually situated apically and about as long (or at least as long) as segment.
