The morphological ontogeny of Minunthozetes semirufus (C.L. Koch, 1841) is redescribed and illustrated. The juveniles of this species have a humeral organ and a gastronotal shield, which bears four pairs of setae (dm, dp, lp, h1) in the larva, and 10 pairs (d-, l-, h-series, p1) in the nymphs. In the larva, the anterior part of gastronotal shield (pygidium) reaches the insertions of setal pair dm. In the juveniles, the prodorsal and gastronotal setae are short, and in the nymphs setae of c-series are inserted on separate microsclerites. In the larva, 12 pairs of gastronotal setae are present, including h3, in the nymphs there are 15 pairs. In the nymphs of M. semirufus, solenidion ω2 on tarsus I is located anterolateral to solenidion ω1, whereas in the adult it is located posterior to ω1. In the tritonymph, seta l' is added on femora I and II, whereas seta l" on these femora is added in the adult, which is unique in Punctoribatidae.
重新描述并图示了半红小甲螨（Minunthozetes semirufus (C.L. Koch, 1841)）的形态个体发育过程。该物种的幼螨具有肩器官和背板盾，在幼虫期背板盾上有四对刚毛（dm、dp、lp、h1），若螨期有十对（d -、l -、h系列、p1）。在幼虫期，背板盾（尾板）前部到达刚毛对dm的着生处。在幼螨中，背板前部和背板刚毛较短，在若螨中，c系列刚毛着生于独立的微小骨片上。幼虫期有12对背板刚毛，包括h3，若螨期有15对。在半红小甲螨若螨中，跗节I上的感觉器ω2位于感觉器ω1的前外侧，而在成螨中它位于ω1的后方。在三龄若螨中，股节I和II上增加了刚毛l'，而在成螨中这些股节上增加了刚毛l"，这在缝甲螨科中是独特的。
