Notes: The original description of Gamasholaspis akimotoi ( Ishikawa, 1966) referred to 39 pairs of setae on the dorsal shield, but the accompanying illustration shows 28 pairs on the shield and 11 pairs in the soft integument. Ishikawa (1980b) described and illustrated the dorsal shield of this species as bearing 29 pairs of setae. The discrepancy appears to be a seta in the r series, which was illustrated in the soft integument in 1966 and on the shield in 1980. The original description shows the podonotal setae as short, not reaching the insertion of the next seta in series. In 1980 these setae are illustrated as much longer, often reaching or surpassing the next seta in series. The 1966 description shows the sternal shield narrow, separate from the endopodal plates between coxae I/II and II/III. The 1980 illustration shows the sternal shield fully fused with the endopodal plates. It is possible that two or more species have been confused here, and we agree with Marchenko (2002) that all records of this species should be carefully revised.
