New sacculonotic Oripodoidea (Acari: Oribatida) from Peru.

Three new species of oribatid mites of the superfamily OripodoideaScheloribates (Bischeloribates) eduardoi sp. nov., Scheloribates (Hemileius) dianae sp. nov. (both from Scheloribatidae) and Peloribates (Peloribates) elisabethae sp. nov. (Haplozetidae)are described from soil and leaf litter of the primary evergreen lowland rainforest in Amazonian Peru. An identification key to known species of Scheloribates (Bischeloribates) is updated. The taxonomic status of the genus Tentaculozetes Balogh, 1970 (Haplozetidae) is discussed, resulting in the following new taxonomic proposal: Peloribates (Peloribates) Berlese, 1908 (=Tentaculozetes Balogh, 1970 syn. nov.).

Ontogenetic instars of Melanozetes paramollicomus sp. nov., with remarks on morphological ontogeny of Sphaerozetinae (Acari: Oribatida: Ceratozetidae).

Although the juvenile instars of oribatid mite subfamily Sphaerozetinae is well known compared to the other subfamilies of Ceratozetidae (Ceratozetinae and Trichoribatinae), information on morphological ontogeny of some species is still incomplete. Herein, Melanozetes paramollicomus sp. nov. is proposed from Ethiopia, based on adult and juvenile instars. Additionally, comparative analysis of ontogenetic instars of species belonging various genera of Sphaerozetinae with known juveniles, is given, and the major characteristics of juvenile instars of 20 species are presented.

Ontogenetic instars of Hermannia longisetosa Subas amp; Shtanchaeva, 2013, with remarks on juveniles of Hermanniidae (Acari: Oribatida).

Information on the morphological ontogeny of the majority species of the family Hermanniidae is still lacking. In this work, the ontogenetic instars of the Mediterranean species, Hermannia longisetosa Subas Shtanchaeva, 2013 are studied, based on material from northwestern Spain. Comparative characteristics of juveniles of species belonging to different genera of Hermanniidae are given based on our own data and available literature sources, and the major characteristics of larvae and nymphs are presented. An updated family and generic diagnoses based on juveniles of Hermanniidae are proposed. At the moment, the juveniles of two genera, Hermannia and Phyllhermannia are known, which differ from one another in the pattern of cuticle plications of the gastronotum; number of solenidia on leg tarsi I and II; number of setae on palp femur; setal formula of leg IV in protonymph; and the arrangement of gastronotic setae of c- and d-series.
