The pronghorn spiny lobster Panulirus penicillatus is a highly valuable species which is widely distributed in Indo-West Pacific and Eastern Pacific regions. Mitochondrial DNA control region sequences (566-571 bp) were determined to investigate the population genetic structure of this species in the Indian Ocean. In total, 236 adult individuals of Panulirus penicillatus were collected from five locations in the Indian Ocean region. Almost all individuals had a unique haplotype. Intrapopulation haplotype (h) and nucleotide (π) diversities were high for each locality, ranging from h = 0.9986-1.0000 and π = 0.031593-0.043441. We observed distinct genetic isolation of population located at the northwestern and southwestern edge of the species range. Gene flow was found within localities in the central and eastern region of the Indian Ocean, probably resulting from an extended planktonic larval stage and prevailing ocean currents.
高背龙虾Panulirus penicillatus是一种极具价值的物种，广泛分布于印度-西太平洋和东太平洋地区。为了研究该物种在印度洋的种群遗传结构，我们测定了线粒体DNA控制区序列（566-571 bp）。总共从印度洋地区的五个地点采集了236只高背龙虾成年个体。几乎所有个体都有独特的单倍型。每个地点的种群内单倍型（h）和核苷酸（π）多样性都很高，范围分别为h = 0.9986-1.0000和π = 0.031593-0.043441。我们观察到位于该物种分布范围西北边缘和西南边缘的种群存在明显的遗传隔离。在印度洋中部和东部地区的各地点之间发现了基因流动，这可能是由于浮游幼体阶段延长和盛行洋流导致的。
