Spinicaudatan clam shrimps are an evolutionarily ancient lineage restricted to temporary freshwater pools. Use of classical morpho-taxonomic approaches alone have led to some issues in the taxonomy of this group, which are now being resolved through integrative taxonomy. Here, we describe two new leptestherid spiny clam shrimps Leptestheria chalukyae sp. nov. and Leptestheria gomantaki sp. nov. from peninsular India based on their unique morphological characters and distinct phylogenetic position. We also re-describe Leptestheria nobilis and present an overview of the morphological characters of all the Indian leptestherids. Most of the conventional taxonomic characters appear to overlap among all the Indian species, although the combination of occipital condyle shape and the cercopod marginal spines arrangement in combination, appear to be useful in separating leptestherid species.
旋口镖形目淡水介形虫是一类演化古老的生物，仅局限于暂时性的淡水池塘中。仅使用经典的形态分类方法，导致该类群的分类学出现了一些问题，现在正在通过综合分类学来解决。在这里，我们根据其独特的形态特征和独特的系统发育地位，描述了来自印度半岛的两种新的旋口镖形目有刺淡水介形虫 Leptestheria chalukyae sp. nov. 和 Leptestheria gomantaki sp. nov。我们还重新描述了 Leptestheria nobilis，并概述了所有印度 Leptestheria 的形态特征。尽管组合使用枕骨突起形状和触角足边缘刺的排列方式似乎有助于分离 Leptestheria 物种，但大多数传统的分类学特征似乎在所有印度物种中都有重叠。
