The genus belongs to the family Tristiridae, an orthopteran group that is distributed across the transitional region of South America and represented in the Andean areas of Peru, Argentina, and Chile. The species of have morphological adaptations that make them especially suited for surviving in extreme arid environments and are an endemic and eremic group of the north-central region of Chile. On the basis of field samplings, direct observations, and a comprehensive literature review, we collected information about the genus . The objectives of this research were: (i) to provide updated information on the geographical distribution range of the species of the genus , and (ii) to collect and synthesize the most relevant information on the natural history and ecology of this orthopteran group as a basis for future long-term studies of its populations. Although this genus is underrepresented compared to other orthopteran families, it has developed interesting adaptations to extreme arid environments that remain unstudied to this date. is known to be one of the species with a wider latitudinal distribution, mostly on the coast and longitudinal valley of Atacama. has a more restricted distribution, whereas is concentrated in coastal and interior environments of the Coquimbo region, an area where it reaches high population densities, thus affecting crops and natural vegetation and polluting water sources. Our findings underscore the importance of conducting comprehensive research on native insect groups that are poorly known but crucial for arid and semiarid ecosystems. These data will serve as a starting point for conducting long-term studies on this orthopteran group to gain a better understanding of the importance and role of these species in the semiarid ecosystems of northern Chile.
该属隶属于三刺蝗科，三刺蝗科是直翅目昆虫中的一个类群，分布于南美洲的过渡地区，在秘鲁、阿根廷和智利的安第斯地区也有代表。该属物种具有形态适应性，使其特别适合在极端干旱环境中生存，是智利中北部地区的特有且分布稀少的类群。基于野外采样、直接观察以及全面的文献综述，我们收集了关于该属的信息。本研究的目的是：（i）提供该属物种地理分布范围的最新信息，以及（ii）收集并综合关于这个直翅目类群自然历史和生态学的最相关信息，作为未来对其种群进行长期研究的基础。尽管与其他直翅目科相比，该属的研究较少，但它已经发展出了对极端干旱环境有趣的适应性，而迄今为止仍未得到研究。已知[具体物种名称1]是分布纬度较广的物种之一，主要分布在阿塔卡马的海岸和纵向山谷。[具体物种名称2]的分布更为局限，而[具体物种名称3]集中在科金博地区的沿海和内陆环境，在该地区它达到了很高的种群密度，从而影响农作物和自然植被，并污染水源。我们的研究结果强调了对鲜为人知但对干旱和半干旱生态系统至关重要的本地昆虫类群进行全面研究的重要性。这些数据将作为对这个直翅目类群进行长期研究的起点，以便更好地理解这些物种在智利北部半干旱生态系统中的重要性和作用。
