Abstract

Large branchiopod crustaceans are flagship species of temporary water bodies, especially in arid and semi-arid regions. Less information is available about the large branchiopods of tropical Asia compared to other parts of the world such as the Americas. To reduce this disparity, we surveyed large branchiopods from the semi-arid region of Maharashtra state, India. Sampling at 29 sites over four years revealed nine species representing four orders. This is the highest diversity ever reported from a single regional study in India. Anostracans were the most commonly occurring group, whereas the spinicaudatans Leptestheria cf. nobilisSars, 1900, L. jaisalmerensisTiwari, 1962, and Eulimnadia michaeliNayar & Nair, 1968 were very rare. Leptestheria jaisalmerensis had been known previously only from its type locality nearly 1,200 km north of our study region. Congeneric assemblages of the anostracans Streptocephalus dichotomusBaird, 1860 + S. simplexGurney, 1906 and the spinicaudatans Leptestheria cf. nobilis + L. jaisalmerensis were collected. Temporary aquatic habitats are threatened due to adverse anthropogenic activities, especially in developing countries like India. The endemic species of large branchiopods in the Indian subcontinent should be red-listed, as is done elsewhere.
印度西部半干旱地区的大型枝足类动物(Anostraca、Notostraca、Laevicaudata、Spinicaudata
大型枝足类甲壳动物是临时水体的旗舰物种,尤其是在干旱和半干旱地区。与美洲等世界其他地区相比,有关亚洲热带地区大型甲壳动物的资料较少。为了缩小这一差距,我们调查了印度马哈拉施特拉邦半干旱地区的大型枝脚类动物。经过四年在 29 个地点的取样,我们发现了代表四个目的九个物种。这是迄今为止在印度进行的单一地区研究中发现的最高多样性。梭形目动物是最常出现的类群,而刺尾目动物 Leptestheria cf. nobilisSars, 1900、L. jaisalmerensisTiwari, 1962 和 Eulimnadia michaeliNayar & Nair, 1968 则非常罕见。Leptestheria jaisalmerensis 以前仅在我们研究地区以北近 1 200 公里处的模式产地为人所知。我们还收集到了梭鱼 Streptocephalus dichotomusBaird, 1860 + S. simplexGurney, 1906 和刺鱼 Leptestheria cf. nobilis + L. jaisalmerensis 的同属组合。由于不利的人类活动,特别是在印度等发展中国家,临时水生生境受到威胁。应像其他地方一样,将印度次大陆特有的大型枝足类物种列入红色名录。
