The morphological ontogeny of Ceratozetes parvulus Sellnick, 1922 is described and illustrated. Some aspects of its ecology are also investigated. The juveniles of this species have short prodorsal and gastronotal setae, tubercles and transverse folds on the gastronotum and setiform bothridial seta. Most leg setae are short, thick and strongly reduced (lack of setae l on femur III of deutonymph and tritonymph, pl on tarsus I, it on all tarsi, and pv on tarsus IV of nymphs), which are unique in Ceratozetes Berlese, 1908. This species is common in peatlands, where it seems to prefer specifically drier microhabitats, like hummocks.
描述并图示了小角蝉 Ceratozetes parvulus Sellnick, 1922 的形态发生。还研究了其生态学的一些方面。该物种的幼体在背前部和腹部具有短的刚毛、小瘤和横褶皱，以及具刺状的两叉刚毛。大多数腿刚毛短而粗，强烈退化（若虫和三龄若虫的腿 III 上没有刚毛 l，跗节 I 上没有刚毛 pl，所有跗节上没有刚毛 it，以及 nymph 的跗节 IV 上没有刚毛 pv），这在角蝉属 Ceratozetes Berlese, 1908 中是独特的。该物种在泥炭地中很常见，似乎特别喜欢更干燥的小生境，如丘。
