Based on material from aquatic habitats in the northern Chihuahuan Desert and a literature review, we present an account on the occurrence of genus Rhinoglena in North America. Two new species are described, and the presence of Rhinoglena frontalis in the USA is confirmed. Of the two new species, R. texana n. sp. is a close relative of R. frontalis, whereas R. ovigera n. sp. is unique by being oviparous, in contrast to all other Rhinoglena which are viviparous. This prompts a revision of the generic diagnosis of Rhinoglena to accommodate the new species. An identification key to the known species of the genus is provided.

AbstractMorphology, distribution, and habitat data are presented for three species of the oribatid mite genus Gymnodampia Jacot occurring in North America. A revised generic diagnosis is given and the type species Gymnodampia setata (Berlese) is redescribed based on topotypic material from Missouri. Immatures of G. setata are described and aspects of their biology are presented. Two new species from North America, G. jacotisp. nov. and G. lindquistisp. nov., are proposed and described on the basis of adults, and a key is given for North American species of Gymnodampia. The ameroid genera Cristamerus Hammer, from Pakistan and China, and Defectamerus Aoki, from Japan, Korea, and China, are considered junior synonyms of Gymnodampia, and G. conformis (Fujikawa) is considered a junior synonym of G. fusca (Fujikawa). Immatures of G. setata are apheredermous, but with a circular line of dehiscence, whereas known immatures of the superfamily Ameroidea are eupheredermous. Nonetheless, without convincing apomorphic traits linking Gymnodampia to any known apheredermous family of Brachypylina, we hypothesize that Gymnodampia has lost the eupheredermy characteristic of Ameroidea, and we place it in the family Ameridae on the basis of adult similarities.

Two New Species

Two new species of oribatid mites of the genus Mainothrus (Oribatida, Trhypochthoniidae)—M. paratransaltaicus sp. nov. and M. davidmarshalli sp. nov.—are described on the basis of adult specimens sampled from Russia and Brunei (first record of the genus in the Oriental region). Supplementary description (SEM micrographs) for Mainothrus badius (Berlese, 1905) is presented. A revised generic diagnosis and an identification key to known species of Mainothrus are provided.

Mite Genus

The genus Eutegaeus (Oribatida, Eutegaeidae) comprises 13 species, which are distributed in the Australian, Neotropical and Antarctic regions; of these, two new species are described from litter in the relictual Valdivian forest of Chile. Eutegaeus parapapuaensis sp. nov. (description based on the adult and tritonymph) differs from Eutegaeus papuensis Aoki, 1964 by the absence of translamella, interbothridial tubercles, notogastral setae h3 and epimeral setae 3a. Eutegaeus paralagrecai sp. nov. (description based on the adult and proto-, deuto- and tritonymph) differs from Eutegaeus lagrecai Arcidiacono, 1993 by the presence of lanceolate bothridial setae and long notogastral setae p1, and the absence of striate ornamentation on the notogaster. A revised generic diagnosis and an identification key to known species of Eutegaeus are presented. Nymphs of Eutegaeus and related genera in Eutegaeoidea are compared.

AbstractTwo new species, Ameletus minimus sp.nov. and Ameletus quadratus sp.nov., are described and illustrated from material collected in Oregon. Diagnostic features for these two species and their relationships with other Ameletus species are discussed. An identification key to the western species of the Ameletus celer Group is also included.

Two New Species

Two new species, Laonice costaricensis sp. nov. and L. rasmusseni sp. nov., belonging to the subgenus Norgensia Sikorski et al., 2017 were found in material from the Pacific collected from Coco Island off the coast of Costa Rica and from the Atlantic collected from Sapelo Island off the coast of Georgia (USA), respectively. Laonice cosaricensis is very close morphologically to L. lemniscata but without transdorsal membranes and having as usual capillaries in several anterior parapodia arranged in three vertical rows. Laonice rasmunsseni has genital pouches starting much anteriorly than in all known species from this subgenus. An identification key for the species belonging to this subgenus is given.

The genus Mesotritia (Oribatida, Oribotritiidae) was represented by eight species in China prior to this work. In this study, two new species, Mesotritia baxoiensis sp. nov. from Tibet and Mesotritia paranitida sp. nov. from Xinjiang, are described. An identification key to Chinese species of Mesotritia is provided to facilitate the further study on this group.
