AbstractHersiliidae Thorell is a family of conspicuously long-legged spiders, characterized by extremely elongate posterior lateral spinnerets. To date, it includes 148 species distributed within seven genera, of which Tama Simon is the only one recorded in the Neotropical Region. Of the 23 known Tama species, 18 are exclusively Neotropical. In order to enhance the scientific knowledge on the family and its members this study presents a cladistic analysis and a taxonomic revision of the Neotropical and Nearctic hersilids. The cladistic analysis places the Neotropical and Neartic species in two separate clades, none of which are closely related to the genus Tama. Based on this result, Tama mexicana (O.P.-Cambridge) and T. forcipata (F.O.P.-Cambridge) are transferred to Neotama and three new genera are proposed to include the remaining species: Ypypuera n. gen. to include T. crucifera Vellard and T. vittata (Simon); Iviraiva n. gen. to include T. pachyura Mello-Leitão and T. argentina Mello-Leitão; and Yabisi n. gen to include T. habanensis Franganillo. Based on the taxonomic revision, eight synonymies are proposed: Tama crulsi Mello-Leitão, Tama micrura Mello-Leitão and T. occidentalis Schenkel with Ypypuera crucifera (Vellard); T. brasiliensis Piza and T. karinae Carcavallo with I. pachyura (Mello-Leitão); T. catamarcaensis Carcavallo and T. longipes Carcavallo with I. argentina (Mello-Leitão); and T. guianensis Mello-Leitão with Neotama mexicana (O.P.-Cambridge); three names are placed as nomina dubia: Tama americana (Simon), T. albigastra Mello-Leitão and T. sasaimae Mello-Leitão and four new species are described: Neotama cunhabebe, from São Paulo, Brazil, Neotama obatala, from Bahia, Brazil, Ypypuera esquisita, from Quevedo, Ecuador, and Yabisi guaba, from Pedernales, Dominican Republic. The family Hersiliidae, the genus Neotama and all three new genera, as well as all Neotropical and Nearctic species are redescribed and diagnosed and a identification key is presented.

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.

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.

The family Harrimaniidae (Hemichordata: Enteropneusta) is revised on the basis of morphological characters. The number of harrimaniid genera is increased to nine by the addition of Horstia n. gen., Mesoglossus n. gen., Ritteria n. gen. and Saxipendium, a genus previously assigned to the monospecific family Saxipendiidae. The number of species is increased to 34, resulting from the description of five new species from the eastern Pacific — Horstia kincaidi, Mesoglossus intermedius, M. macginitiei, Protoglossus mackiei and Ritteria ambigua. A description is supplied for a sixth harrimaniid species, Stereobalanus willeyi Ritter & Davis, 1904, which previously had the status of a nomen nudum. Four harrimaniids previously assigned to the genus Saccoglossus are transfered to the genus Mesoglossus — M. bournei, M. caraibicus, M. gurneyi and M. pygmaeus, while Saccoglossus borealis is reassigned to the genus Harrimania. Notes on habitat and zoogeography are included for the seven foregoing species and a table of diagnostic characters for existing and new species and a dichotomous key to the enteropneust families and harrimaniid genera are provided. Finally, a phylogenetic hypothesis concerning the Harrimaniidae is postulated, with discussion on the evolution of the group.

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.
