A new pterygosomatid mite species, sp. n. (Acariformes: Pterygosomatidae) was collected from two specimens of (Liolaemidae) from Argentina. This new species is described based on active stages: adults (female and male) and juveniles (deutonymphs, protonymphs, and larvae) and quiescent stages (nymphchrysalis, deutochrysalis and imagochrysalis). The changes in morphological characters that occur during the ontogeny of have been analyzed in detail. A difference in larval sex morphology was observed for the first time in the family Pterygosomatidae (female larvae differ from male larvae in terms of the shape and size of the idiosoma and the position of the genital area). This new mite species is most similar to but can be distinguished by the presence of different leg chaetotaxy patterns of genua IV and femora IV, four to six genital setae, three to five dorsomedial setae, and two to three ventromedial setae. Phylogenetic analysis was conducted based on 120 morphological characters of all spp. and four outgroup species using the maximum parsimony approach. The results indicated that this species is nested within mites of the group of associated with host species of the section of s. str. An updated diagnosis of the group of and an identification key for all species of this genus has been provided.
从阿根廷的两种鬃狮蜥（Liolaemidae）标本中采集到一种新的翼头螨科螨类物种，新种（蜱螨亚纲：翼头螨科）。该新物种根据活跃阶段进行描述：成螨（雌螨和雄螨）和幼螨（若螨、前若螨和幼虫）以及静止阶段（若蛹、后蛹和成虫蛹）。详细分析了该螨在个体发育过程中发生的形态特征变化。在翼头螨科中首次观察到幼虫性别形态的差异（雌螨幼虫在体躯形状和大小以及生殖区位置方面与雄螨幼虫不同）。这种新螨物种与[某物种]最为相似，但可通过第四膝节和第四股节不同的足刚毛排列模式、四至六根生殖刚毛、三至五根背中刚毛以及二至三根腹中刚毛来区分。基于所有[该属]物种以及四个外群物种的120个形态特征，采用最大简约法进行了系统发育分析。结果表明，该物种嵌套在与[某属]狭义[某亚属]宿主物种相关的[某组]螨类中。提供了[该组]的最新诊断以及该属所有物种的鉴定检索表。
