Competition for food and habitat seems insignificant, possibly because the groundwater was enriched with particulate organic matter and predators (such as leeches) were not abundant. Leeches are the natural enemies of the shrimp; they attach to the carapace, branchial chambers and appendages where they feed on the hemolymph of the shrimps. Parasitism certainly confers negative impact on populations of the new species, but accurate population data on the shrimp are lacking.</paragraph>

On 25 January 2019, 18 individuals were collected, including two adult males, 10 adult females (six ovigerous), and six subadult females. The sex ratio (male to female) is 1:8, and the percentage of ovigerous females is 60%. On 18 March 2019, 18 individuals were caught, including five adult males, 10 adult females (three ovigerous), and three subadult females. The sex ratio is 1:2.6, and the percentage of ovigerous females is 30%. In 18 February 2020, four individuals were caught including one adult male and three adult females (one ovigerous). The sex ratio is 1:3, and the percentage of ovigerous females is 33%. These results showed that the number of males was significantly less than females in the population from January to March. The causes responsible for the skewed sex ratio in favor of females may worth further study.</paragraph>

Cave shrimp communities are particularly vulnerable to human disturbance, particularly groundwater pollution due to the local agricultural activities (fertilization, herbicide, and pesticide) and overexploitation (domestic usage and agricultural irrigation). These appear to be responsible for the pollution and degradation of subterranean habitat, but the extent of the impact is a little known. If groundwater become contaminated, local aquatic organisms certainly are at risk. Maintaining healthy groundwater shrimp communities requires the reduction of anthropogenic impacts, such as minimizing the use of agricultural pesticides, herbicides, and fertilizers by local farmers. It is suggested that the local government should ration the use of groundwater resources.</paragraph>

should be considered as a Critically Endangered species due to its exceptional rarity, restricted distribution in a single cave system, and the imminent threats from pollution. In order to better protect cave ecosystems, and their associated rare and threatened evolutionary relict fauna, it is critical and of great urgency to collect more baseline data on population and distribution patterns, delineate the importance and threatened status of cave fauna, and to devise corresponding conservation and management measures. Regular monitoring may be necessary to ensure populations are sustained in the face of further anthropogenic disturbances. Furthermore, cave biodiversity protection laws should be enacted as soon as possible.
