The morphological ontogeny of Perlohmannia nasuta Schuster, 1958 is described and illustrated. The adult of this species is the most similar to that of P. dissimilis (Hewitt, 1908), but differs from it by having alveolar seta exp (versus setiform in P. dissimilis), which is unique in Perlohmannia Berlese, 1916. It also has more spines on the bothridial seta and shorter seta c1 than has P. dissimilis. The juveniles of P. nasuta have the prodorsal seta exp alveolar, 78 anterior spines on the bothridial seta, and seta e2 longer than f2. Clapardes organ of larva is long and cudgel-shaped. This species differs clearly from P. dissimilis in the ontogeny of leg setae. In both species, hypertrichy occurs on tarsi, especially on tarsus I, but P. nasuta has more setae on tarsus I of deutonymph, tritonymph and adult than has P. dissimilis.
描述并图示了 Perlohmannia nasuta Schuster, 1958 的形态发生。该种的成体与 P. dissimilis (Hewitt, 1908) 的成体最为相似，但与后者不同的是，它具有泡状的 exp 刚毛（而 P. dissimilis 的为刚毛状），这在 1916 年的 Perlohmannia Berlese 中是独一无二的。它的 bothridial 刚毛上的刺也比 P. dissimilis 多，并且 seta c1 比 P. dissimilis 短。P. nasuta 的幼体具有 exp 泡状的前背板刚毛，bothridial 刚毛上有 78 个前刺，并且 seta e2 比 f2 长。幼虫的 Clapardes 器较长且呈棍棒状。该种在腿刚毛的发生上与 P. dissimilis 明显不同。在这两个物种中，跗节上都发生了过度生长，尤其是跗节 I，但 P. nasuta 的 deutonymph、tritonymph 和成虫的跗节 I 上的刚毛比 P. dissimilis 多。
