本文记述钩虾科三新种--拟钩虾Gammarus troglomorphus，sp. n. G. n.小眼斑叶蝉，sp.和Tadzocrangonyx alaicus，sp. n.描述并举例说明了吉尔吉斯斯坦巴特肯地区的植物。本文报道了一个近缘的土库曼斯坦居群G.参见subaequalis-Garlyk，可能与Gammarus subaequalis Martynov，1935年。新物种的亲和力有关类群进行了讨论。为了确定所述物种的系统发育位置，获得DNA条形码数据。钩虾Gammarus troglomorphus和钩虾G. parvioculatus是近邻，但在形态上非常不同。Gammarus troglomorphus是一种穴居动物;小眼龙是真眼龙，但除了眼睛稍小之外，不是真眼龙。两者都只在土库曼斯坦极东的小范围内发现。Gammarus cf. subaequalis-Garlyk似乎从同一地区延伸到吉尔吉斯斯坦东部。
Three new species of the family Gammaridae-Gammarus troglomorphus, sp. n., G. parvioculatus, sp. n. from Lebap Province of Turkmenistan and Tadzocrangonyx alaicus, sp. n. from Batken Region of Kyrgyzstan are described and illustrated. Morphological studies of a closely related Turkmenistan population of G. cf. subaequalis-Garlyk, probably conspecific with Gammarus subaequalis Martynov, 1935 was provided. The affinity of new species to concerned taxa is discussed. To define phylogenetic position of mentioned species DNA barcode data are obtained. Gammarus troglomorphus and G. parvioculatus are close neighbors but exceedingly different morphologically. Gammarus troglomorphus is a troglobiont; G. parvioculatus is an eutroglophile, but with exception of slightly smaller eyes, not troglomorph. Both found only within small areas in the extreme East of Turkmenistan. Gammarus cf. subaequalis-Garlyk seems to extend from the same region far into the eastern Kyrgyzstan.
