Currently, the Onisicdea (terrestrial isopods) is a massive Crustacea suborder of more than 3 700 species, but our knowledge of their paleodiversity is poor. In this paper, we present ten fossils of Crinocheta, the largest clade within the Onisicdea, discovered in Early Miocene (23 Ma) amber of Chiapas. We described three new genera and six new species including Palaeolibrinus spinicornis gen. nov. sp. nov., Armadilloniscus miocaenicus sp. nov., Archeostenoniscus robustus gen. nov. sp. nov., Archeostenoniscus mexicanus sp. nov., Palaeospherarmadillo mazanticus gen. nov. sp. nov., and Palaeospherarmadillo rotundus sp. nov. This study represents the first fossil record of the family Detonidae, Olibrinidae, and “Stenoniscidae”. From a paleoenvironmental reconstruction perspective, the oniscidean fauna presented here supports a particularly wet paleoenvironment, under brackish water influence, similar to an estuary.

Two new genera and two new species of fossil rhopalid, Miracorizus punctatus gen. & sp. nov. and Longiclavula calvata gen. & sp. nov., are described and illustrated. They were collected from the Middle Jurassic Jiulongshan Formation of Inner Mongolia, China. This is the earliest fossil record of the family Rhopalidae in the world.

New Occurrences

With the exception of polycopids, Mesozoic myodocopid ostracods are regarded as uncommon in the fossil record. They are known from a few localities in the Tethys, and most of them are considered to be pelagic forms. However, a relatively rich and taxonomically diverse material is derived from Hungarian sections; these represent various formations deposited during the Triassic to Cretaceous.The aim of this study is to summarize the current knowledge of Mesozoic myodocopids and to provide new information concerning their classification and phylogenetic relations. This includes new occurrences of Triassic entomozoid Schallreuterizoe groosae Kozur, 2004, cylindroleberidid Triadocypris sp., cypridinid Palaeocypridina tulceaensis Sebe, 2013, Jurassic thaumatocyprid Pokornyopsis cf. bettenstaedti (Bartenstein, 1949) and P. feifeli (Triebel, 1941). The revision of the holotype of gigantic Triassic Triadogigantocypris balatonica Monostori, 1991 give new results concerning the valve structure and taxonomic position of the genus. Two new genera (Neorichterina n. gen. and Hungaroleberis n. gen.) and four new species (Neorichterina striata n. sp., Pokornyopsis csurgokutensis n. sp., Hungaroleberis retiferus n. sp. and Palaeocypridina goeroegae n. sp.) of the subclass Myodocopa are described. Moreover, most of the Albian to Cenomanian representatives of “Conchoecia” are newly classified as Entomozoidae (Neorichterina n. gen.), which allows to extend the range of the family up to the Cretaceous. A summary of the relevant assemblages present in Hungary will help to complement the existing, previously published literature on myodocopids, and also clarify details about the phylogenetic model of the group.

A New Species

A new species of scolebythine wasp (Chrysidoidea: Scolebythidae) is described and figured from a female beautifully preserved in Early Miocene amber from the Dominican Republic.  The specimen is the first fossil record of the extant genus <em>Clystopsenella</em> Kieffer, and is quite similar to the extant <em>Clystopsenella longiventris</em> Kieffer, a species that occurs widely from Brazil to Belize.  <strong><em>Clystopsenella mirabilis</em></strong> Engel, new species, is distinguished from <em>C. longiventris</em> on the basis of size; head, pronotal, and pterostigmal shape; and putative color differences.  The living and fossil diversity of the family is summarized and evolutionary patterns within the clade are discussed.

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.

Guţu (2016) described a new subfamily, seven new genera and 21 new species in the family Leptocheliidae. However, another five genera and twelve new species, not mentioned by him, were described in 2015 and 2016. Study of the overlooked genera reveals that the morphology of the female of Permixtimella (genus described from both sexes) is similar to those of the type-female of the genus Ektraleptochelia (whose male is unknown). Permixtimella is considered a junior synonym of Ektraleptochelia, which includes two species: E. phoxops and E. oculifurcillata. The place of Ektraleptochelia, Catenarius and Larsmentia within leptocheliid systematics, formerly in the subfamily Catenariinae, is reconsidered and the last genus retained. Some similarities between the females of Nuberis and Bathyleptochelia are presented for the first time. The species Leptochelia acrolophus, L. mexicana, L. ortizi, L. taitungensis and L. grandidentata are transferred to other genera, becoming Chondrochelia acrolophus, C. mexicana, C. ortizi, C. taitungensis and Makassaritanais grandidentatus, respectively. The species Leptochelia pinarensis and L. suhi are considered a junior synonym of Leptochelia forresti and Makassaritanais grandidentatus, respectively.

The family Diplomaragnidae Attems, 1907 of the Asian part of Russia is reviewed and shown to comprise 11 genera and 60 species + 1 dubious species. Two genera and seven species are described here as new to science: Alineuma gen. nov., with type species A. rodionovi sp. nov. and Litovkia gen. nov., with the type species L. anisimovka sp. nov., Diplomaragna budilovi sp. nov., Diplomaragna dentifer sp. nov., Pacifiosoma shabalini sp. nov., Pacifiosoma acutum sp. nov., Pacifiosoma triangulatum sp. nov. Pacifiosoma asperum Mikhaljova, 2016 is recorded from the Primorsky Krai for the first time. Five genera are endemic to the Asian part of Russia. At the species level, the rate of endemism amounts to 91.7%. A key is given to all species of Diplomaragnidae presently known from Siberia and the Russian Far East. The distributions of the region’s diplomaragnids are discussed. Taxonomic remarks are provided for many species.

Ocala Limestone

Oyenaster oblidus, Ocalaster timucum, and Ocalaster seloyi are new genera and species of the family Goniasteridae (Asteroidea) described from the Eocene Ocala Limestone of Florida. Although the fossil record of asteroids is sketchy, goniasterids appear to have been important contributors to marine communities since at least the Middle Jurassic. Similarities between living goniasterids and their fossil precursors indicate that plesiomorphy and convergence have been important in family history, and as a result, taxonomic interpretation is challenging. Even partial fossil goniasterids are rare, forcing systematists to rely heavily on isolated marginal ossicles, although some authors have expressed the need for caution. Building around three new taxa, we suggest that broader approaches can aid systematic interpretation of all crown-group asteroids. We also suggest that the inevitably idiosyncratic interpretations of marginal-based systematics can be partially tested using blind evaluations.
