AbstractStudy of new collections of the Wenlock and Pridoli, Silurian, crinoids from Saaremaa, western Estonia, result in taxonomic revision, expanded ranges, and new taxa. Eucalyptocrinites regularis and Periechocrinus laevis are recognized outside of Sweden for the first time. Desmidocrinus laevigatus Ausich et al., 2012 is reassigned to Methabocrinus. Because the type species of Methabocrinus was previously known only from glacial sediments, the age and provenance of this genus are constrained for the first time. A new crotalocrinitid, Velocrinus coniculus new genus and species, is described. Although the Pridoli faunas of western Estonia contain only twelve species-level taxa assigned to nine genera, this fauna is one of the four richest Pridoli faunas known.

A new genus of gnaphosid spiders, Almafuerte, gen. nov., is described for seven species from Southern South America. The new genus is diagnosed by a conspicuous retrolateral tegular projection on the male palp, and by having three teeth on the cheliceral retromargin. It comprises six species from Argentina, A. peripampasica sp. nov. (type species), from Central Argentina, also present in Uruguay, A. kuru sp. nov., from Santiago del Estero, A. vigorosa sp. nov., from Corrientes, A. goloboffi sp. nov., from Salta and Jujuy, A. remota sp. nov., from Santiago del Estero and Mendoza, and A. giaii (Gerschman & Schiapelli) comb. nov., here transferred from Echemus, from Santa Fe (the female is here described by the first time); and one species from Bolivia, A. facon sp. nov., from Cochabamba. Hypotheses of relationships of the new taxa are briefly discussed, in the context of the previously proposed groupings: the subfamilies Echeminae and Drassodinae (sensu Platnick 1990) and the “Echemus group” (sensu Murphy 2007).

A taxonomic revision of the tribe Ceroptresini (Hymenoptera: Cynipidae) is conducted for the first time. Prior to this study, the total number of valid species of Ceroptres, the only genus within Ceroptresini to date, was 23. As a result of this revision, 15 Ceroptres species are retained as valid and one species, Amblynotus ensiger Walsh, 1864, is desynonymized from Ceroptres petiolicola (Osten-Sacken, 1861), being considered here as a valid Ceroptres species: C. ensiger (Walsh, 1864) status verified and comb. nov. An additional five new species are described from Mexico: Ceroptres junquerasi Lobato-Vila & Pujade-Villar sp. nov.; C. lenis Lobato-Vila & Pujade-Villar sp. nov.; C. mexicanus Lobato-Vila & Pujade-Villar sp. nov.; C. nigricrus Lobato-Vila & Pujade-Villar sp. nov.; C. quadratifacies Lobato-Vila & Pujade-Villar sp. nov., increasing the total number of valid Ceroptres species to 21. Ceroptres masudai Abe, 1997 is synonymized with C. kovalevi Belizin, 1973. Ceroptres niger Fullaway, 1911 is transferred to Andricus (Andricus confusus Lobato-Vila & Pujade-Villar comb. nov. and nom. nov.). Five species (Amblynotus inermis Walsh, 1864; Cynips quercusarbos Fitch, 1859; Cynips querficus Fitch, 1859; Cynips quercuspisum Fitch, 1859; and Cynips quercustuber Fitch, 1859) are not considered as valid Ceroptres. The status of Ceroptres quereicola (Shinji, 1938), previously classified as an unplaced species, is commented on. In addition, a Nearctic species from the USA, Ceroptres politus Ashmead, 1896, is here proposed as the type species of a new genus within Ceroptresini: Buffingtonella Lobato-Vila & Pujade-Villar gen. nov. Redescriptions, biological and distribution data, illustrations and keys to genera and species within Ceroptresini are provided. The diagnostic morphological traits of Ceroptresini, Ceroptres and the new genus are discussed.

A taxonomic revision and DNA sequence analysis of all species previously attributed to Rulingia R.Br. and Commersonia J.R.Forst. & G.Forst. resulted in two major groupings, referred to a redefined Commersonia and a new genus (Androcalva C.F.Wilkins & Whitlock 2011). In total, 25 species are now recognised within Commersonia, including the type species of Rulingia, and 14 species previously included in Rulingia and 10 in Commersonia. Three of these are described as new (C. apella C.F.Wilkins, C. erythrogyna C.F.Wilkins and C. gilva C.F.Wilkins). A new subspecies, C. magniflora subsp. oblongifolia C.F.Wilkins, is recognised and C. bartramia (L.) Merr. var. tahitensis Dorr is raised to species level as C. tahitensis (Dorr) C.F.Wilkins & Whitlock. Two new combinations are made, Rulingia platycalyx Benth. and R. parviflora Endl. as C. parviflora (Endl.) C.F.Wilkins & Whitlock; and R. cistifolia Steetz and R. rugosa Steetz as C. rugosa (Steetz) F.Muell. The redefined Commersonia is monophyletic and characterised by anthers with sublatrorse dehiscence and mainly hairy staminodes, compared with extrorse dehiscence and glabrous staminodes as seen in Androcalva.

Two Palaearctic genera, Paragona Staudinger, 1892 and Paragabara Hampson, 1926, in the subfamilies Aventiinae and Hypeninae respectively are revised. The genus Paragona is recognized as a member of the subfamily Aventiinae. Paragona nemorata sp. n. is described as new and Paragona inchoata (Wileman, 1911) is reported for China for the first time. The genus Paragabara is recognized as a member of the subfamily Hypeninae. A lectotype is designated for P. flavomacula (Oberthür, 1880) and a new species Paragabara curvicornuta sp. n. described. Paragabara ochreipennis Sugi, 1962 and Remmigabara secunda, comb. n. are reported for the first time from China; Paragabara secunda Remm, 1973 is removed from the genus Paragabara. In addition, a new genus Remmigabara gen. n., with type species Paragabara secunda, is described in the subfamily Aventiinae. Adults and genitalia of the new taxa are illustrated and compared to related taxa.

The leafhopper tribe Agalliini from China is reviewed. The Chinese fauna includes 44 species of 15 genera including four new genera: Purvigallia gen. nov. (type species: Purvigallia maculata sp. nov., from Yunnan), Skandagallia gen. nov. (type species: Skandagallia dietrichi sp. nov., from Yunnan), Sinoagallia gen. nov. (type species: Sinoagallia serrata sp. nov., from Yunnan) and Sungallia gen. nov. (type species: Sungallia truncata sp. nov., from Yunnan). Japanagallia is the most species rich and includes 17 species from China, of which five are new: Japanagallia curvipenis sp. nov. (China: Xizang), Japanagallia decliva sp. nov. (China: Shaanxi), Japanagallia multispina sp. nov. (China: Guangxi, Guizhou, Shaanxi, Yunnan), Japanagallia palmata sp. nov. (China: Yunnan) and Japanagallia sclerotica sp. nov. (China: Shaanxi). The genus Igerna Kirkaldy (with Igerna channa sp. nov from Guangxi and Tibet) and the European species, Anaceratagallia ribauti (Ossianinilsson) have been recorded for the first time from China. All the new taxa are described and illustrated. A check-list with taxonomic notes as well as a generic key to Chinese Agalliini are also provided.

The late Llandovery through late Ludlow sequences of the stable carbonate platform of Gotland (Baltic Basin; western side of the Silurian paleocontinent Baltica) and the carbonate ramp of the Welsh Borderland area in England contain a richly fossiliferous fauna of atrypid brachiopods, including more than 60 species. This was a time of diversification for the atrypids in the tropical equatorial latitudes, with new lineages appearing for the first time that were to dominate the Devonian Period. Included in this burst of new groups was the ribbed atrypid group, the Plectatrypinae (new subfamily), which quickly led to the first spinose atrypids, the Spinatrypinae. For the Plectatrypinae, a new subgenus and species, Plectatrypa (Gutnia) capidula, and a new genus, Xanthea, are described. The evolution of expanded growth lamellae and frills on the shell at this time led not only to the growth of large shells assignable to Atrypa, but also to the rise of affiliated ribbed taxa, such as the perireefal and reefal genus Endrea echoica new genus and species (Wenlock-Ludlow). The nature, affinities and taxonomy of the smooth atrypid Lissatrypa obovata (Sowerby) from the U.K. are also clarified, indicating that the type species for the unrelated genus Glassia needs to be revised.

Four cribrilinid bryozoans associated with deep-water corals (578–682 m depth) from the Great Bahama Bank slope, are described, two of them are new. The generic allocation of some species prompted us to raise the subgenera Puellina, Cribrilaria, and Glabrilaria to genus rank. The new combination Cribrilaria saginata (Winston, 2005) n. comb. is proposed. Genus Glabrilaria is reported from the NW Atlantic for the first time based on the description of Glabrilaria hirsuta Rosso n. sp. and Glabrilaria polita Rosso n. sp. The new genus Teresaspis Rosso n. gen. is erected, and Teresaspis lineata (Canu & Bassler, 1928) n. comb. is proposed as its type species. The new genus Harmelinius Rosso n. gen. is erected for Cribrilina uniserialis (Harmelin, 1978). Both genera have uniserial colonies formed by slightly caudate zooids with extensive gymnocyst and a frontal shield of flattened costae. Teresaspis lineata n. comb., however, has costae with pelmatidia that are connected by few intercostal bridges and separated by intercostal spaces, four orificial costa-like processes with the proximal pair arching above the orifice, hyperstomial acleithral ovicells with a pseudoporous ooecium formed by the distal zooid or a kenozooid, two types of kenozooids (large with costate frontal shield and small with smooth shield and central opesia), and an ancestrula with costate frontal shield. Avicularia are apparently absent in this species. In contrast, the type species of Harmelinius Rosso n. gen. has costae lacking pelmatidia and which are separated by slit-like intercostal spaces. The hyperstomial cleithral ovicells have smooth ooecia with a median suture and without pseudopores, and are formed by a distal kenozooid associated with a small avicularium. Additional paired oral avicularia are occasionally present, as are large kenozooids with a central opesia. Oral spines or spine-like processes are absent. Taxonomy of the above reported cribrilinid genera is discussed in detail together with the geographic distribution of all mentioned taxa.

Coronabrotica, a new genus of Diabroticina Section Phyllecthrites (Luperini) is proposed from the Neotropical Region with the type-species Coronabrotica amazonensis Moura sp. nov. from states of Pará and Amazonas, north of Brazil. The new genus differs from others of the Section by the anterior coxal cavities being closed and, in males, by a rounded pore on the basal half of the pronotum, surrounded by a crown of long erect setae. Descriptions and illustrations of the new taxa and a key for the identification of the thirteen genera that compose the Section Phyllecthrites are provided.
