Six new species of Eocene brachiopods are described, one being referred to a new genus. One previously-described species is named and referred to a new genus; additional records are given for an eighth species. Five of these are from England, two from France and one from Africa.     

New species and records of earthworms from Jamaica with notes on the genus Eutrigaster Cognetti, 1904 (Octochaetidae: Oligochaeta)

Details are presented of earthworm collections from Jamaica. Eleven species are reported, eight being new records of which two are new species, to bring the total number of species known from the island to 16 and the number of families represented to six. The geographical affinities of each species and its faunal status are summarized. The new species are members of the genus Eutrigaster Cognetti (Octochaetidae) whose validity is reviewed; a table is provided for the identification of the 11 Central American and Caribbean species currently included in the genus.     

A taxonomic revision of the Oriental spittlebug genus Paphnutius Distant (Homoptera: Cercopidae)

The spittlebug genus Paphnutius is transferred from the Tomaspidini to the Considiini. The genus is revised and redescribed to contain nine species. A key to species is given and all species are redescribed and illustrated with their distributional data provided. One new species is described and one new generic synonymy, six new specific synonymies and four new combinations are established. Five lectotypes are newly designated. Paphnutius costimaculus Metcalf and Horton is considered as a species incertae sedis.     

An overview of Hexabathynella (Crustacea,Syncarida, Parabathynellidae) with the description of a new species

A new species of the cosmopolitan genus Hexabathynella is described from Spain. This new species has four setae on the expopod of the uropod, the rest of the species in the genus have between one and three. The endopod of the uropod has two smooth setae of similar length and one plumose seta, these characters only appear in the new species within the genus. The antennal organ in the males is shown to be a new unique character for the genus. It is the third species of this genus that has been found in Spain. To date the genus consists of 18 species in the world. A key for identification of the 18 species of Hexabathynella is provided. It is the only cosmopolitan genus of Bathynellacea and it is distributed in Europe (nine species), Africa (one species), South America (two species), North America (three species) and Australia and New Zealand (three species).     

On a new genus and species of centipede (Chilopoda,Geophilomorpha, Chilenophilidae) from the British Isles

A new genus and species of geophilomorph centipede, Nothogeophilus turki is described from the Scilly Isles and the Isle of Wight. The precise relationships of this new genus are not clear. The species is, presumably, an introduction.     

Australian thrips of the Haplothrips lineage (Insecta: Thysanoptera)

Keys are presented to the 11 genera and 50 species, including 21 new species, of Thysanoptera in Australia that are related to the worldwide genus Haplothrips Amyot and Serville. These taxa belong to what, in recent literature, has been called the “Haplothrips‐lineage”, that is, one of the three major radiations among the 2700 species and 350 genera of Thysanoptera Phlaeothripinae. The group is redefined, and the available tribal name Haplothripini shown to be appropriate. The character states on which the definition is based are discussed, and a list given of the 34 genera worldwide that can be included. The Australian species in these genera exhibit a diversity of biologies. Three genera involve species that invade galls induced by other thrips: Androthrips monsterae (Moulton) from New Guinea is newly recorded from Australia; Mesothrips jordani Zimmermann from South‐East Asia is newly recorded from Australia, with two new synonyms; the Asia‐Pacific genus, Euoplothrips Hood, includes two species in northern Australia. Three haplothripine genera are associated with grasses: one widespread genus, Apterygothrips Priesner, considered polyphyletic, includes only one Australian species; the only known species of Dyothrips Kudo is Oriental but extends into tropical Australia; Podothrips Hood, a circum‐tropical genus of thrips predatory on grass‐living coccoids, has 11 Australian species, six newly described. One grass‐associated genus, Bamboosiella Ananthakrishnan, is excluded from the Haplothripini. An Oriental genus of leaf‐ and flower‐living species, Dolichothrips Karny, includes one species in northern Australia, D. reuteri (Karny); Membrothrips Bhatti in which this species has been placed is considered a synonym. Karnyothrips Watson includes two species introduced to Australia, both predators of coccoids. Priesneria Bagnall includes three species from Australia, of which one fungus‐feeding species is newly described. Xylaplothrips Priesner is a widespread but ill‐defined, polyphyletic genus that currently includes three little‐known Australian species. Haplothrips is the main focus of this study, and character state variation among the Australian species is discussed. In total 24 species of Haplothrips from Australia are recognised, 14 being new species. Also included are the following, one new generic synonym, four new species synonyms, and one new combination. The 250 species worldwide in the genus are usually associated with the flowers of Asteraceae and Poaceae. In Australia, several of the species are specific to flowers, particularly of Poaceae and Cyperaceae but not Asteraceae. Almost half of these Australian species are presumed to be predatory on other small arthropods, and two have unusual host associations—with salt marsh Chenopodiaceae, and with the sori of Dicksonia tree ferns.     

Two new species of Neosophia Guimarães, 1982 and first description of female of Neoeuantha sabroskyi Guimarães, 1982 (Diptera: Tachinidae)

Neosophia Guimarães is a monotypic genus with Neotropical distribution that belongs to the tribe Sophiini. Neosophia guimaraesi sp. nov. from Amazonas, Brazil, and Neosophia bispinosa sp. nov. from Costa Rica are new species described for this genus. The female of Neoeuantha sabroskyi Guimarães, 1982 is described for the first time. First-instar larvae and illustrations of the female terminalia are described and illustrated for both new species.     

New South American leafhoppers in the genus Docalidia , with a key to 37 species (Cicadellidae: Coelidiinae, Teruliini)

Ten new species of Docalidia are described and illustrated. These are pennyi, gracilitas, zanoli, triquetra, paracrista, convexa, setacea, and caterva from Brazil and vesica and vella from Peru. A key to males of 37 species described since the last revision of the genus is included. The number of known species is now 116, making Docalidia the largest teruliine genus.     

New Notiodes semiaquatic weevil (Curculionidae) from sporocarps of Marsilea mollis (Marsileaceae) in southern Arizona, USA

A new species from the semiaquatic weevil genus, Notiodes sporocarpicus, which develops and pupates in the sporocarps of the water fern Marsilea mollis B.L. Rob. & Fernald, is described from cattle tanks in southeastern Arizona. This new species can be separated readily from the majority of the known species by its nearly straight rostrum, with its distinctive dorsally swollen base and attenuated apex. Its elongate and slender body will separate N. sporocarpicus from most species in the genus except N. aeratus, which lacks the characters above. The Texas species N. celatus resembles the new species but has strongly developed suberect curved setae that are not present in N. sporocarpicus. Included are habitus photos and line drawings of the male and female genitalia of the new species.     

The Afrotropical thermophilic ant genus Ocymyrmex (Hymenoptera: Formicidae)

The taxonomy and biology of the Afrotropical thermophilic ant genus Ocymyrmex is reviewed and updated. A new key to workers for the 37 recognized species is presented and species-groups within the genus are delimited. Revised genus-level diagnoses for all castes are given and a check-list with known distributions of all species is included. Nine new species are described. The previously known biology of the genus is reviewed in the introduction and fresh biological and ecological information on a number of species is given in the introduction and under the individual species headings.     

Description of four new species of Hersiliidae (Arachnida,Araneae) from Kinabalu National Park,Sabah, Borneo,Malaysia

The family Hersiliidae includes, to date, seven genera and 148 species, distributed throughout tropical, subtropical and warm temperate zones. Of these, five genera and 30 species have been recorded from the Oriental region. In this paper, three new species of the genus Hersilia Audouin and one new species of the genus Tamopsis Baehr and Baehr are described from Kinabalu National Park, Sabah, Borneo, Malaysia.     

Three new Brazilian species of the land planarian Choeradoplana (Platyhelminthes: Tricladida: Geoplaninae), and an emendation of the genus

Three new Brazilian species of the neotropical land planarian genus Choeradoplana (Platyhelminthes: Tricladida: Continenticola: Geoplaninae) are described, making a total of nine species within the genus. All the new species share unique derived characters typical of the genus. Two of the new species exhibit important features representing morphological variations that were previously unknown for the genus: the dorsal cutaneous longitudinal muscle layer, as well as the ventral one, partially sunken into the parenchyma in one species, and the common ovovitelline duct approaching the copulatory apparatus ventrally in the other. As a consequence of these morphological variations, an emendation of the genus is proposed.     

New genus and species of leafhopper in the tribe Tinobregmini (Homoptera: Cicadellidae: Coelidiinae)

A new genus, Stenolidia , and new species, S. magna (type species), are described and illustrated. Stenolidia from Guyana is the fifth genus in the tribe Tinobregmini and the third that has come to light since the tribe was revised in 1975.     

A revision of the new riodinid butterfly genus Pseudotinea (Lepidoptera: Riodinidae)

A revision of the new South American riodinid genus Pseudotinea is presented that includes taxonomic and ecological notes, distributional data and illustrations of adults and genital structures for all species. The systematic position of Pseudotinea within the Riodinidae, its ecology and biogeography are discussed. Five species are recognized: volcanicus Callaghan and Salazar, hemis Schaus and caprina Hewitson are transferred from Calydna (comb. n.) and two new species, P. eiselei and P. gagarini, are described here. The genus is confined to the Andes and south-east Brazil where all species are very rare and many endangered.     

Two zoogeographically remarkable mite species from Finland (Acari,Oribatida, Oribotritiidae)

Species of the genus Mesothuria (fam. Synallactidae) occurring in the Atlantic Ocean are revised. The genus includes 25 valid species, nine of them known from the Atlantic. The new species Mesothuria milleri sp. nov. is described from the north-east Atlantic. It is argued that the genus Zygothuria, established by Perrier in 1898 and recognized later only by Deichmann, should be maintained as a separate genus. Mesothuria and Zygothuria differ in body form, arrangement of ambulacral appendages, and structure of segments of calcareous ring and ossicles from the body wall. The six known species of Zygothuria are reviewed. Zygothuria oxysclera, a former variation of Zygothuria lactea, is proposed as a valid species. Identification keys to species of the genus Zygothuria and Atlantic species of the genus Mesothuria are provided. Data on the life history and reproductive biology of Mesothuria milleri and Zygothuria lactea are given. Both species are common in the north-east Atlantic.     

The genus Thoradonta in Thailand (Orthoptera: Tetrigidae: Scelimeninae) with description of two new species

The genus Thoradonta Hancock (Orthoptera: Tetrigidae: Scelimeninae) is newly reported from Thailand. Two new species of the genus, Thoradonta lativertexoides sp. nov. and Thoradonta spiculobaoides sp. nov., are described and illustrated with photographs and compared with similar species. A taxonomic review of the genus Thoradonta is provided and a key to all known species of the genus is given.     

Expanding the taxonomic conundrum: Three new species of groundwater crustacean (Syncarida,Bathynellacea, Parabathynellidae) endemic to the Iberian Peninsula

Two new species of the genus Iberobathynella and one new species of the cosmopolitan genus Hexabathynella are described from the Iberian Peninsula. The three new species were found in the groundwater of caves and the gravelly bank of a river, two species in the north of Spain (Cantabria and Burgos) and one in the south (Sevilla). The two new species of the genus Iberobathynella present a unique combination of characters. These character combinations for the species from Cantabria are: thoracopod 8 female with wrinkled cuticle and two teeth; seven spines on the furca; nine spines on the sympod, three barbed and one plumose seta on the exopod and two barbed setae on the endopod of the uropod; maxilla with 0, 0 and 15 setae on the three segments, respectively; five teeth on the pars incisiva and six teeth on the pars molaris of the mandible and seven segments on the antennule. The combinations of characters for the species from Burgos are: antennule with seven segments; segment 5 of the antennule with one aesthetasc; mandible with four and five teeth on the pars incisiva and pars molaris respectively; maxillule with one seta on segment 1 and 14 setae on segment 3; segment 1 of the endopod of the thoracopod 1 with two setae; uropod with six spines on the sympod, four barbed setae and one plumose seta on the exopod and no setae on the endopod; furca with five spines and the thoracopod 8 female with wrinkled cuticle and two teeth. This last species has an exclusive character for the genus: the absence of setae on the endopod of the uropod. The new species of the genus Hexabathynella has six spines of similar length on the sympod of the uropod (in all other species within the genus the distal spine is longer than the others); the form of the antennal organ in the males is shown to be a new unique character for the genus; the maxilla has three and 13 setae on segments 2 and 3, respectively; the uropod has six spines on the sympod, three barbed setae on the exopod and two smooth setae on the endopod, the endopod is twice as long as the exopod and the shape of the female thoracopod 8 is unique.
