ABSTRACT

The morphological ontogeny of Oribatella reticulata Berlese, 1916 is described and illustrated. The nymphs of this species are apopheredermous, i.e. they carry the exuvial scalps of previous instars away from the dorsal integument, using modified setal pair da. The larva has 12 pairs of gastronotal setae, including short h₃, the nymphs have 15 pairs, and most are long and barbed. In all juveniles, a humeral organ is absent, which is unique in Oribatella. The tritonymph of this species has more thickened setae on leg segments (d on all femora and genu IV, ev’ on femora III and IV, l on femora I–III and genua and tibiae I–IV) than the adult (l” on genua and tibiae I and II, l’ on genu and tibia IV).

摘要

描述和说明了网纹Oribatella reticulata Berlese，1916年的形态学。该物种的若虫无皮，即使用改良后生对da使它们背离先前的幼虫的出没头皮远离背被膜。幼虫有12对胃肠道刚毛，包括短h ₃，若虫有15对，多数是长而有刺的。在所有少年中，肱骨器官都不存在，这在Oribatella中是独一无二的。与成人相比，该物种的三叶虫在腿节上的刚毛增厚（在所有股骨和属IV上为d，在股骨III和IV上为ev'，在股骨I-III和属和胫骨I-IV上为l）。l”代表Genua和胫骨I和II，l'代表Genu和胫骨IV。
