The oribatid mite genus Caleremaeus (Caleremaeidae) is widely distributed in the northern hemisphere but has been represented by only three extant and one fossil species. We redescribe the North American C. retractus (Banks, 1947) based on adults and nymphs; it is distinguishable from the European type species, C. monilipes (Michael, 1882) by its smaller adult size and minor differences in cuticular structure, and by the elongated, tapered form of seta h1 in nymphs. Two new species are proposed: C. nasutus n. sp. from forest soil in Alabama is unique in having adults with a large anterior rostral lobe (juveniles unknown) bearing lamellar setae; the arboreal C. arboricolus n. sp. from eastern USA and Canada is unique among described extant species in having adults with femoral saccules, a transverse ridge bearing lamellar setae and relatively large notogastral setae, and juveniles with a bothridial seta similar to that of the adult. Based on all available data, Caleremaeus is redescribed and considered the sole genus in Caleremaeidae. The higher classification of the family is reviewed, and past placement in Ameroidea is rejected in favor of the monofamilial Caleremaeoidea.

A New Species

AbstractThe family Peradeniidae (Hymenoptera: Proctotrupoidea) is represented by two rare extant species from southeastern Australia (Australian Capital Territory, Victoria, Tasmania). A new species, Peradenia galerita sp. n., is described from Eocene Baltic amber. The fossil species is very similar to the living Perndenia, but has the short metasomatic petiole typical of most Proctotrupoidea. The subfamily classification of Heloridae proposed by Rasnitsyn and the status of Peradeniidae are briefly reviewed. The subfamily Mesohelorinae Rasnitsyn, 1990 is a junior synonym of Protohelorinae Rasnitsyn, 1980 (syn. n.).

A list of identified oribatid mite taxa from Uganda, including 21 species/subspecies from 17 genera and 14 families, is presented. A new species of the family Machadobelbidae is described from leaf litter. Machadobelba ugandaensis sp. nov. differs from Machadobelba barbata Sanyal, Saha & Chakraborty, 2005 and Machadobelba dispar Balogh, 1958 by the presence of one pair of lateral teeth of the rostrum, prodorsal transverse ridge between costulae and foveolate body surface. Revised generic diagnosis and an identification key to the known species of Machadobelba are presented.

AbstractSeven new species of Milichiella are described from Dominican amber: M. archaia n. sp., M. dolichosurstyla n. sp., M. dominicana n. sp., M. hennigi n. sp., M. margaretae n. sp., M. quadrisetosa n. sp., and M. theodori n. sp. These species represent the first record of the sub-family Milichiinae in amber and the first descriptions of the family in Dominican amber. The fossil species differ from extant species only in species-level details except M. archaia, which probably belongs to the stemline of Milichiella + Ulia.

The New World family Syringogastridae (Diptera, Acalyptratae) with the single genus Syringogaster is revised. Eleven new extant species are described in four newly recognized species groups to give a total of 20 extant species (S. brachypecta, S. apiculata and S. tenuipes in the rufa-group; S. atricalyx, S. figurata, S. plesioterga, and S. dactylopleura in the figurata-group; and S. nigrithorax, S. brunneina, S. sharkeyi and S. palenque in the brunnea-group; Marshall & Buck are the authors of all extant new species). The craigi-group includes two new fossil species, S. miocenecus Grimaldi and S. craigi Grimaldi, each described on the basis of a unique Miocene (ca. 17 myo) amber specimen from the Dominican Republic. Morphological and molecular characters are used to estimate phylogenetic relationships among species of Syringogastridae, and between Syringogastridae and related diopsids. The fossil species appear to form the sister group to the Central and South American figurata group, and reveal Antillean extinction of the family from earlier in the Tertiary.

The oribatid mite family Hungarobelbidae is widely distributed in the northern hemisphere, but has been represented by only two genera and eight known species. Herein, we propose a remarkable new species, Hungarobelba nortonroyi sp. nov. based on adults from western USA, exhibiting curious mixtures of character states of both genera of this family, Costeremus and Hungarobelba. Based on available data, we assess current views of the family-level classification of Costeremus rejecting its placement in Damaeolidae, and a close relationship is suggested between Costeremus and Hungarobelba. Also, recent transfer of the damaeid genus Tokukobelba to Hungarobelbidae is reversed, as there are no synapomorphies linking the latter two taxa. Furthermore, a brief note on habitat ecology and biogeography of hitherto know species is given, and a key for the identification of adults of the known genera and species of Hungarobelbidae in the world, is provided.

The Family

Tree snails in the family Partulidae are widespread across the tropical Pacific, with endemic species occurring on most high islands. Partulid species have faced catastrophic range reductions and extinctions due primarily to introduced predators. Consequently, most extant species are threatened with imminent extinction. The U.S. administered Mariana Islands, consisting of Guam in the South and the Commonwealth of the Northern Mariana Islands (CNMI) in the north, historically harbored six endemic partulid species, half of which are thought to be extinct. While conducting a phylogenetic assessment of Partula gibba, an extant tree-snail with a range spanning at least seven islands within the archipelago, it was discovered that what has been identified as P. gibba on the island of Rota is a misidentified cryptic species. Here we use molecular phylogenetics, shell morphometrics and reproductive anatomy to describe it as a new species, Partula lutaensissp. nov.. Because the new species has suffered population declines and has a restricted range, consisting solely of the small island of Rota, we highlight the urgent need for conservation measures.

The genus Airapus Stebnicka & Howden, 1996 currently comprises 26 extant species distributed in the Australian and Oriental zoogeographical regions (Stebnicka & Howden 1996; Stebnicka 1998, 2009; Rakovič et al. 2019; Král et al. 2019; Minkina 2020) and one fossil species from the Eocene Baltic amber (Tamutis et al. 2017). Of the continental Southeast Asia, only three species have been known so far: Airapus cechovskyi Král, Mencl & Rakovič, 2019 (mainland Malaysia: Kelantan), A. tyri Král, Mencl & Rakovič, 2019 (Central Thailand: Phetchaburi Province) and A. sicardi ( Paulian, 1945) (Laos: “Cochinchine: Long Xuyen” and South Vietnam: “Annam: Tanh Hoa”) (Paulian 1945; Balthasar 1964; Král et al. 2019). Examination of the material housed in the collections of the Institute of Zoology, Chinese Academy of Sciences, Beijing, China, revealed Airapus material belonging to an undescribed species. Its formal description is presented in this paper. This new species is another, fourth species occurring in mainland Southeast Asia. It is also the first country record from China. The geographical distribution of the genus is now known to the north as far as Fujian Province.

Two New Species

Leaves of three species belonging to the family Araucariaceae are described from two Eocene localities in Tasmania. Araucarioides gen. nov. is proposed to contain the fossil species. The erection of a new genus is necessary for two reasons. Two new species, A. linearis and A. sinuosa, are intermediate between Agathis and Araucaria and do not have the Florin rings which are the characteristic of extant species of Araucariaceae. The third new species, A. annulata, while clearly belonging to the Araucariaceae, is not well enough preserved to be assigned to an extant genus. These species confirm the presence of the subtropical/tropical Araucariaceae in Tasmania in the Eocene. The evolutionary position of the fossil species is uncertain at present.

Three New Species

Resuming published and own data, a revision of classification of Chaetognatha is presented. The family Sagittidae Claus & Grobben, 1905 is given a rank of subclass, Sagittiones, characterised, in particular, by the presence of two pairs of sac-like gelatinous structures or two pairs of fins. Besides the order Aphragmophora Tokioka, 1965, it contains the new order Biphragmosagittiformes ord. nov., which is a unique group of Chaetognatha with an unusual combination of morphological characters: the transverse muscles present in both the trunk and the tail sections of the body; the seminal vesicles simple, without internal complex compartments; the presence of two pairs of lateral fins. The only family assigned to the new order, Biphragmosagittidae fam. nov., contains two genera. Diagnoses of the two new genera, Biphragmosagitta gen. nov. (type species B. tarasovi sp. nov. and B. angusticephala sp. nov.) and Biphragmofastigata gen. nov. (type species B. fastigata sp. nov.), detailed descriptions and pictures of the three new species are presented.

Abstract Bryozoans with calcified frontal shields formed by the fusion of costae, collectively constituting a spinocyst, are traditionally assigned to the family Cribrilinidae. Today, this family is regarded as nonmonophyletic. In the Argentine Cenozoic, cribrilinids were until recently represented by only two fossil species from the Paleocene of Patagonia. This study describes the first fossil representatives of Jolietina and Parafigularia: J. victoria n. sp. and P. pigafettai n. sp., respectively. A fossil species of Figularia, F. elcanoi n. sp., is also described. The material comes from the early Miocene of the Monte León and Chenque formations (Patagonia, Argentina). For comparison, we also provide redescriptions of the remaining extant species of Jolietina: J. latimarginata (Busk, 1884) and J. pulchra Canu and Bassler, 1928a. The systematic position of some species previously assigned to Figularia is here discussed. Costafigularia n. gen. is erected, with Figularia pulcherrima Tilbrook, Hayward, and Gordon, 2001 as type species. Two species previously assigned to Figularia are here transferred to Costafigularia, resulting in C. jucunda n. comb. and C. tahitiensis n. comb. One species of Figularia is reassigned to Vitrimurella, resulting in V. ampla n. comb. The family Vitrimurellidae is here reassigned to the superfamily Cribrilinoidea. The subgenus Juxtacribrilina is elevated to genus rank. Inferusia is regarded as a subjective synonym of Parafigularia. Parafigularia darwini Moyano, 2011 is synonymized with I. taylori Kuklinski and Barnes, 2009, resulting in Parafigularia taylori n. comb. Morphological data suggest that these genera comprise different lineages, and a discussion on the disparities among cribrilinid (sensu lato) spinocysts is provided.
