Chromatophore distribution patterns in the first and second zoeae of atyid shrimps (Decapoda: Caridea: Atyidae) : a new technique for larval identification

西日本に分布する両側回遊性ヌマエビ類5種,ヒメヌマエビCaridina serratirostris,トゲナシヌマエビC.typus,ミゾレヌマエビC.leucosticta,ヤマトヌマエビC.japonica,およびヌマエビ(小卵型)paratya compressa compressaの第1・第2ゾエア期幼生について,腹部の色素胞の位置と形状を観察し,それらの出現傾向を記載した.さらにこれを利用して第1・2ゾエア期幼生の種を識別する方法を示し,検索表を作成した.
The abdominal chromatophores of the first and second zoeae were examined in five amphidromous atyid shrimps, which are widely distributing in southwest Japan: Caridina serratirostris De Man, C. typus H. Milne Edwards, C. leucosticta Stimpson, C. japonica De Man, and Paratya compressa compressa (De Haan) (small egg type). Chromatophore distribution pattern of larvae was found to be an effective character to identify respective species.
