Triops cancriformis of synonymy to support it. This was in a taxonomic review of the Notostraca that also supported using the genus name "Triops" instead of "Apus". In 1958, the International Commission on Zoological Nomenclature (ICZN) recognised the name "Triops cancriformis" (Bosc, 1801–1802) (ICZN name no. 1476) as officially the oldest. They also recognised the genus name "Triops" Schrank instead of "Apus". They followed Longhurst in these decisions. Although members of the genus "Triops" usually have no economic importance, the Beni-kabuto ebi albino variant of "Triops cancriformis" has been used to control mosquitoes and weeds in Asian rice fields. "Triops cancriformis" is
