A taxonomic revision of the stygobiont microsnails from north-western Transcaucasia (Krasnodar Krai, Russia) is presented. Two new genera—Schapsugia gen. n. and Tachira gen. n. are established. It is shown that the genus Paladilhiopsis does not occur in this area, and the snails previously assigned to this genus belong to Schapsugia gen. n. Two nominal species Paladilhiopsis orientalis Starobogatov, 1962, and P. subovata Starobogatov, 1962 are considered junior synonyms of Sch. pulcherrima (Starobogatov, 1962), based on a re-examination of their conchological variation. In addition, two more species of Schapsugia are described: Sch. kudepsta sp. nov. and Sch. occultata sp. nov. The anatomical structure of another species, Geyeria valvataeformis Starobogatov, 1962 was studied for the first time. It is revealed that it should be placed in a separate genus (Tachira gen. n.). Thus, the previously proposed placement of the microsnails from north-western Transcaucasia in hydrobiid genera from the Balkan Peninsula (Geyeria, Paladilhiopsis) is rejected.

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.

Phyxioschema raddei Simon, 1889 is revised. A re-examination of type specimens confirms the synonymy of P. raddei and Ischnothele strandi Spassky, 1937, but the synonymy of Afghanothele lindbergi Roewer, 1960 and A. striatipes Roewer, 1960 cannot be confirmed due to the immature state of their types. The copulatory organs of the female holotype and other females from different localities are illustrated for the first time. Variation in morphological characters is shown. New records are given for Iran, Turkmenistan, Uzbekistan, Kazakhstan and Tajikistan. Phyxioschema females from Pakistan cannot be attributed to any nominal species and are left unnamed. A new species, P. roxana, is described from male and female specimens collected at eight localities in southern Uzbekistan and western Tajikistan. Relationships between Central Asian and Southeast Asian species are discussed. A summary of relevant morphological characters of all Phyxioschema species is given.

Abstract Since the taxonomic revision of the Ophidiasteridae by H.L. Clark (1921), in which 20 genera were recognized as valid, several new genera and species were included in this family, and the boundaries between some of them became largely arbitrary. This also applies to Narcissia Gray, 1840, whose morphology and taxonomy are still very poorly understood today. The main goals of this research were: review the taxonomy of the genus Narcissia, from morphological studies; redescribe N. trigonaria Sladen, 1889s. str.; characterize N. canariensis (d'Orbigny, 1839) and N. gracilis A.H. Clark, 1916, the two valid species most similar to N. trigonaria; review the validity of N. ahearnae Pawson, 2007 and N. trigonaria var. helenae Mortensen, 1933; review the validity of N. gracilis malpeloensis Downey, 1975. Altogether 370 specimens were analysed. All morphological structures of taxonomic importance have been illustrated, and, for the first time, the internal characters of this group were studied, from electron microscopy and microtomography. A new diagnosis for the genus Narcissia was constructed. Narcissia trigonaria was redescribed from a large specimen, from the type locality (Bahia, Brazil). Narcissia ahearnae is considered a valid species, and N. canariensis and N. trigonaria distinct entities. Narcissia trigonaria var. helenae is placed in the synonymy of N. trigonaria, and N. gracilis malpeloensis into the synonymy of N. gracilis. The dataset obtained in this work is by far the most complete acquired for the genus Narcissia.

The spider genus Ariadna Audouin, 1826 currently comprises 102 of 127 described species of Segestriidae. Its distribution comprises all continents (except Antarctica), but it is mostly found on the tropical and subtropical regions. We present a comprehensive taxonomic revision of Ariadna in the American continent, including 2,519 specimens (i.e., type and non-type) from 30 arachnological collections. We present 31 nominal species, among which eight species are new to the science: Ariadna reginae n. sp. from Central America; Ariadna aurea n. sp., Ariadna caparao n. sp., Ariadna gaucha n. sp., Ariadna ipojuca n. sp., Ariadna lemosi n. sp. and Ariadna ubajara n. sp. from Brazil; and Ariadna lalen n. sp. from Chile. Nine species are proposed as junior synonyms: A. pragmatica Chamberlin, 1924 and A. scholastica Chamberlin, 1924 with A. bicolor (Hentz, 1842), A. gracilis Vellard, 1924 and A. conspersa Mello-Leitão, 1941 with A. obscura (Blackwall, 1858), A. murphyi (Chamberlin, 1920) with A. tarsalis Banks, 1902, A. pusilla (Nicolet, 1849) and A. ashantica Strand, 1916 with A. maxima (Nicolet, 1849), A. dubia Mello-Leitão, 1917 with A. boliviana Simon, 1907, and A. spinifera Mello-Leitão, 1947 with A. mollis (Holmberg, 1876). Ariadna comata O. P.-Cambridge, 1898 is revalidated. Two species became nomina dubia: Ariadna solitaria Simon, 1892 and A. tubicola Simon, 1893. The allotype of A. crassipalpa described by Camargo (1950) and the paratype of A. levii described by Grismado (2008), were identified as A. mollis and A. maxima, respectively and have been considered as misidentifications. The male of A. cephalotes and A. comata, and the female of A. calilegua are described for the first time.

Brachychiton Schott & Endl. has previously been included under Sterculia and its generic status has been uncertain. Characters of the follicles, seed coats and embryo strongly support the retention of Brachychiton as a separate genus. The genus comprises five sections, including one new section, Oxystele Guymer. Characters useful in identification and classification are reassessed and those found to be of most significance are described in detail and illustrated. Chromosome numbers of 2n = 40 for 12 species are recorded for the first time. Keys for the identification of taxa are given. Detailed new descriptions, distribution (including a map based on herbarium specimens), ecology, conservation status and relationship are provided for each taxon, and most taxa are illustrated. Taxa described as new are: B. acuminatus, B. albidus, B. chillagoensis, B. collinus, B. compactus, B. diversifolius subsp. orientalis, B. fitzgeraldianus, B. grandiflorus, B. megaphyllus, B. muellerianus, B. multicaulis, B. obtusilobus, B. populneus subsp. trilobus, B. spectabilis, B. tridentatus and B. xanthophyllus. The following five new combinations are made: B. garrawayae (Bailey) Guymer, B. tuberculatus (W. Fitzg.) Guymer, B. viridiflorus (W. Fitzg.) Guymer, B. viscidulus (W. Fitzg.) Guymer and B. vitifolius (Bailey) Guymer. Naturally occurring hybrids within the genus are frequent between partially sympatric species. Eight hybrids are recorded and described: B. x allochrous, B. x carneus, B. x excellens, B. x hirtellus, B. x incarnatus, B. x roseus, B. x turgidulus and B. x vinicolor.

Parsimony Criterion

Chelodesmidae is one of the most diverse families belonging to the Polydesmida, comprising almost 800 described species distributed in 172 genera, 20 tribes and two subfamilies. Among the tribes within the Neotropical subfamily Chelodesminae, Arthrosolaenomeridini represents a very interesting group occurring in the Central-West region of Brazil. Currently the tribe contains three genera: Arthrosolaenomeris Schubart, 1943, Gangugia Schubart, 1947, and Angelodesmus Schubart, 1962. In this study, we conducted a cladistic analysis including 18 species of Arthrosolaenomeridini and 7 species of other associated Chelodesminae tribes as an outgroup. The matrix is composed of 64 morphological characters from which 39 are herein proposed for the first time. The data were analyzed under the parsimony criterion using TNT 1.5. Based on the results, Arthrosolaenomeridini was recovered as monophyletic with Macrocoxodesmini + Telonychopodini as sister group. Arthrosolaenomeris Schubart, 1943 and Gangugia Schubart, 1947 were recovered as monophyletics. The genus Angelodesmus Schubart, 1962 was recovered as paraphyletic and redefined as monotypic. The tribe is now composed of the genera Arthrosolaenomeris (6 spp.), Gangugia (6 spp.), Angelodesmus (monotypic), Abiliodesmus n. gen. (4 spp.) and Folcloredesmus n. gen. (monotypic). In addition, we conduct a taxonomic revision of the tribe Arthrosolaenomeridini providing detailed redescriptions, drawings, and distribution maps for all species and genera, including the two new genera and the ten new species proposed: Arthrosolaenomeris saci n. sp.; A. curupira n. sp.; A. caipora n. sp.; A. iara n. sp.; Gangugia boitata n. sp.; G. cuca n. sp.; G. boto n. sp.; G. mula n. sp.; Abiliodesmus mapinguari n. sp. and Folcloredesmus thomasi n. sp. Furthermore, we include an identification key to all the genera and species.
