A new oribatid mite subgenus, Parabelbella (Paradyobelba) subgen. nov. (Oribatida, Damaeidae), characterized by unusual tubercular anterior propodolateral apophyse PA in combination with tubercular  apophyses P, Sa and Sp, with type species Parabelbella (Paradyobelba) elchacoensis sp. nov., is proposed and described from Ecuador. The relations between genera Parabelbella and Dyobelba are discussed on the background of two major lineages within Dameidae. Parabelbella dimidiaspina Xie, Yan & Yang, 2013 is recombined in Dyobelba.

Direct Investigation

The oribatid mite family Archaeorchestidae was proposed based on a single specimen of Archaeorchestes minguezae Arillo & Subías, 2000, from Lower Cretaceous amber (Spain). In a previous paper we redescribed Strieremaeus illibatus Sellnick, 1918, from Eocene Baltic and Rovno amber, and considered Strieremaeus a senior synonym of Archaeorchestes. Herein, we transfer a second genus, Plategeocranus, to Archaeorchestidae. This is based on a redescription of the type species, P. sulcatus (Karsch, 1884), using non-type specimens (44 adults and 2 immatures from Baltic and Rovno ambers). Among these are eight Baltic amber specimens identified by Max Sellnick and currently housed in two museums in Kaliningrad: from the Museum of the World Ocean we designate specimen #39 as neotype and specimens 22, 30, 33, 35 and 37 as paraneotypes; from the Kaliningrad Museum of Amber we designate specimens 197-22 and 197-54 as paraneotypes. The contention of Arillo and Subías that Archaeorchestidae is a member of Zetorchestoidea (Eremaeoidea auct.), and is the extinct sister-family of Zetorchestidae, is supported with additional characters that relate to leg setation and the morphology of immatures. The possible inclusion of another Cretaceous fossil mite, Rasnitsynella punctulata Krivolutsky, in Archaeorchestidae or Zetorchestoidea was rejected, leaving it in Plateremaeidae pending the direct investigation of specimens. New diagnoses are presented for Plategeocranus, Archaeorchestidae, and Zetorchestoidea.

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.

The present work deals with two members of the oribatid mite subgenus Galumna (Cosmogalumna) Aoki, 1988 from Japan. A new species, G. (C.) centroclathrata n. sp. is morphologically most similar to G. (C.) praeoccupata Subías, 2004 from China; however it differs from it by conspicuous granular ornamentation on the surface of the pteromorph, the shape of the polygonal sculpture on the notogaster, and a conspicuous linear sculpture on the middle part of the genital plates. Galumna (Cosmogalumna) ornata Aoki, 1988, the type species of the subgenus, is additionally described based on the specimens from the type locality. The position of lamellar setae slightly anteriad to L lines and the presence of 10 pairs of minute notogastral setae should be considered in any future identification of G. (C.) ornata.

Oribatid Mite Species

In the literature there is much confusion about the identity and taxonomic position of two common oribatid mite species in the family Ceratozetidae: Oribates setosus C.L. Koch, 1839, and Murcia trimaculata C.L. Koch, 1835. Related to these problems, there are contrary opinions about the validity of two ceratozetid genera, Murcia Koch, 1835 and Trichoribates Berlese, 1910, and the identity of their type species. Important conclusions on these issues have been proposed in the past (Jacot 1929; Pérez-Iñigo 1993) but these were not followed in an important recent catalog (Subías 2004). In the following, we summarize and comment on the history of these problems, and argue in the context of the current ICZN rules to preserve nomenclatural stability.

Mite Genus

A new oribatid mite genus, Sculpteremaeus gen. nov. (Oribatida, Cymbaeremaeidae), with Sculpteremaeus olszanowskii sp. nov. as type species, is proposed and described based on adults. It is from sandy soil-litter in chaparral of California, USA, an environment from which no oribatid mites have been recorded previously. Based on an analysis of adults of all genera of Cymbaeremaeidae, the new genus is closely related to Ametroproctus, from which it is most easily distinguished by the morphology of lamellae, size of lamellar cusps, and shape of the tutorium. We expand the Cymbaeremaeidae family diagnosis, and question the inclusion of Scapheremaeus based on extensive molecular evidence showing its closer relationship with Ameronothroidea and Licneremaeoidea.

First Time

Strieremaeus is one of several oribatid mite genera proposed by Max Sellnick based on adult specimens preserved in Eocene Baltic amber. The original specimens of its type-species—S. illibatus Sellnick, 1918—were lost and the genus has received no further empirical study. For many years Strieremaeus was included in the family Eremaeidae, but recently this placement was questioned. Herein we redescribe S. illibatus based on the study of 31 non-type adult specimens from both Baltic and Rovno ambers. Among these are four Baltic specimens identified by Sellnick and currently deposited in the Kaliningrad Museum of Amber (KMA), which we designate as neotype (KMA 197-36) and paraneotypes (KMA 197-34, 197-35, and 197-37). Six immature specimens were associated with this species, of which three—one deutonymph, two tritonymphs—could be studied in detail and their characters are included in the redescription. The type specimens of a second species of Strieremaeus proposed by Sellnick—S. cordiformatus Sellnick, 1918—are also lost and two non-type specimens in the KMA seem to have been misidentified by Sellnick; therefore, we treat S. cordiformatus as a species inquirenda. A new diagnosis of Strieremaeus is presented, and the Cretaceous fossil genus Archaeorchestes is considered a junior subjective synonym, based on examination of the holotype of the type-species, A. minguezae Arillo & Subías, 2000. As a consequence, Strieremaeus is currently the sole genus in Archaeorchestidae. Strieremaeus minguezae (n. comb.) is only tentatively maintained as a distinct species, as no certain distinguishing traits could be found. Two families are reported from the fossil record for the first time: Zetomotrichidae from Baltic amber and Zetorchestidae from Rovno amber. In ancillary discussion we note how the specialized tarsal structure of S. illibatus is consistent with its likely arboreal habitat. We also discuss preservation properties and artifacts, note the dimensional discrepancy between cuticular remnants of the mite and its larger imprint in amber, and strongly recommend measuring more than the cuticular remnants themselves. Further, we provide information on different methods to observe amber inclusions, and for the first time report birefringence of fossil cuticular remnants in thin, airless preparations.

AbstractThe oribatid mite genus Ametroproctus, soil and litter inhabitants in the desert, alpine, and montane regions of western North America, is discussed. Two subgenera are recognized, Ametroproctus s. str. and Coropoculia. Their respective type-species, A. oresbios Higgins and Woolley and C. reticulata Aoki and Fujikawa, are redescribed, and newly discovered immatures of both species are described. Four new species are proposed, A. (Ametroproctus) tuberculosus, A. (A.) aridus, A. (Coropoculia) beringianus, and A. (C.) canningsi. A new generic diagnosis is given, as well as a key to subgenera and species known from North America.

The oribatid mite family Camisiidae is commonly recognized to include four genera and about 100 nominal species, all of which appear to be asexual. Based on adult specimens from Valdivian forest litter in Osorno Province, Chile, we propose a monotypic fifth genus, Paracamisia gen. n., with type species P. osornensis sp. n. This is the first genus of the family that is not represented in the Northern Hemisphere. Like all other known Camisiidae it seems to be asexual. Paracamisia osornensis sp. n. is distinguishable from other camisiids by its shiny, convex notogaster that lacks a suprapleural scissure, and by its large respiratory bothridial saccule. A preliminary analysis suggests that its closest relatives are to be found in the genus Platynothrus.
