The taxonomy of the widespread camel spider, Rhagodes eylandti (Walter, 1889), is herein updated and revised by proposing three nominal taxa as its junior synonyms. These are based on data from males of two taxa, Rhagodes melanopygus nigricans Birula, 1905 and R. plumbescens (Walter, 1889), and a female of R. melanochaetus Heymons, 1902. Consequently, both sexes of R. eylandti are re-described and the validity of their morphological diagnostic characters is evaluated. Detailed morphological and morphometrical characters, as well as data on sexual dimorphism and intraspecific variations, are provided. The illustrations of type material are given for the first time. Moreover, a distribution map and ecological notes are presented.

The genus Oplognathus MacLeay, 1819 is revised based on type material of two of the three described species and scattered additional material from several collections around the world. The diagnostic characters of the genus are confirmed, distinguishing it from other Brazilian Areodina mainly by: quadrangular clypeus with trilobate apex in males, rounded in females, extending beyond labrum in both sexes; mandibles with three distinct teeth; maxillae with six teeth; antenna with 10 antennomeres; 10 elytral striae; mesoventral process present; and asymmetrical parameres. The genus and all three species are redescribed, and the female of Oplognathus bahianus Ohaus, 1912 is described for the first time. We consider Oplognathus helmenreichi var. maculicollis Ohaus, 1914 an unavailable infrasubspecific taxon that is conspecific with Oplognathus helmenreichi Ohaus, 1905; its distribution is updated, and the different spelling of the specific epithet is discussed. A neotype is designated for Oplognathus kirbii MacLeay, 1819 since the holotype is currently considered lost. Additionally, an identification key and a distribution map are included.

A study of the holotype of Pinnotheres hemphilli Rathbun, 1918, revealed it is an early post-hard female, not a male, of Fabia Dana, 1851. The morphology of Pinnotheres emiliai Melo, 1971 (based on a male specimen) and Fabia insularis Melo, 1971 (based on a female specimen) confirm earlier hypothesis that they belong to a sexually dimorphic species that should be known as F. emiliai (Melo, 1971). The redescription of the holotype of Fabia felderi Gore, 1986, supports its generic assignment and its relationship with F. emiliai. The implication of sexual dimorphism and intersexes in the taxon-omy of Fabia is discussed.

A New Species

The oribatid mite genus Oribatella includes over 100 named species, none of which shows distinct sexual dimorphism in the octotaxic system of dermal glands. We propose a new species of this genus, Oribatella canadensis sp, nov., collected from dry soil habitats in western Canada, that shows distinct dimorphism in these dermal glands, the first record of this dimorphism in the Oribatelloidea. The posterior pair of glands in males, but not females, is enlarged and associated with a shallow, medial pit-tubercle complex, and is generally similar to convergent dimorphisms in some genera of Mochlozetidae (Oripodoidea), Mycobatidae (Ceratozetoidea) and Galumnidae (Galumnoidea). We describe this species based on adult and nymphal stages, and expand the diagnosis of the genus to accommodate the newly described immatures. We review the expression of sexual dimorphism in brachypyline oribatid mites and discuss its association with periodically dry habitats.

A New Species

A new species Neoribates isabelaensis sp. nov. showing an interesting sexual dimorphism is described from bamboo litter on Luzon Island in the Philippines. This species is unique among other species of Neoribates in the structure of the posterior part of notogaster in males, which has a large round concavity bearing a pair of large sacculi S3. The specific function of this structure is not yet known, but the found sexual dimorphism is presumably involved in pheromonal communication allowing rapid sperm transfer. This is the fourth Neoribates species displaying sexually dimorphic characters. Additionally, Neoribates isabelaensis sp. nov. differs from the morphologically most similar species, Neoribates barbatus Hammer, 1968, by its smaller body size, pointed rostrum, long and setiform bothridial setae and the localization of notogastral setae h1 and h2, which insert close to each other. Further, we discussed all cases of sexual dimorphism in the family Parakalummidae as well as other related groups of Oripodoidea, and the possible function of these modifications.

A new species of the genus Lemaireia Nässig & Holloway, 1988 (Lepidoptera: Saturniidae: Saturniinae: Saturniini), L. daparo sp. n., is described from evergreen broad-leaf forests in Panzhihua (Sichuan), Qujing (Yunnan) and Dali (Yunnan) of China. The new species resembles L. luteopeplus aureopeplus Nässig & Holloway, 1988 and L. hainana Nässig & Wang, 2006 from China, but can be easily separated from them by the male genitalia. In addition, the genus Lemaireia is reported here for the first time from Sichuan Province, and now its distribution range reached the northeastern extreme point. The habitus, diagnostic characters and distribution map of the three species of the genus Lemaireia from China are provided. A list of all Lemaireia species presently known worldwide is also given.

The chelodesmid genus Atlantodesmus Hoffman, 2000 is revised and considered a senior synonym of Iemanja Hoffman, 2000. Currently the genus contains five species, all of them are herein redescribed: Atlantodesmus eimeri (Attems, 1898), Atlantodesmus itapurensis (Schubart, 1943), Atlantodesmus pickeli (Schubart, 1946), Atlantodesmus pintoi (Schubart, 1946), and the transferred species from Iemanja, Atlantodesmus teresa (Hoffman, 2000), new combination. The female of Atlantodesmus teresa is described for the first time. Examination of the type material of Leptodesmus buecherli Schubart, 1955 revealed that this species is a junior synonym of A. itapurensis. A key to males and a distribution map of all species are included.

Ecologic Studies

Background and aims: Juncus is the largest and most diverse genus of Juncaceae, distributed mainly in the temperate zones of both hemispheres. The Southern Cone flora contains ca. 38 Juncus species (44 taxa including 12 infraspecific categories). Sixteen of those species belong to the section Ozophyllum. As a part of our ecologic studies in wetlands of Patagonia (Argentina) we collected specimens of Juncus that did not match any of the species currently known to the Southern Cone. The aim of this contribution is to report for the first time the presence of Juncus articulatus subsp. articulatus for the Southern Cone flora.  M&M: Classical methods in taxonomy were employed. Living and herbarium material, original descriptions, and type material of Juncus articulatus subsp. articulatus were studied. Collected materials were deposited in the herbarium ARC of the Universidad Nacional del Comahue. Results: Juncus articulatus subsp. articulatus is here described. A distribution map, photos, and a key to the Southern Cone species of Juncus belonging to the section Ozophyllum are provided. Also, some ecological and distributional features are discussed.  Conclusions: The naturalization of Juncus articulatus subsp. articulatus is reported here for the first time in the Southern Cone. From now on, Juncus contributes 39 species to the Southern Cone flora, and 17 to Juncus section Ozophyllum.

Lectotypes are designated for Zyras exasperatus Schubert, 1908, Z. drescheri Cameron, 1939, Z. gratellus Cameron, 1939, Myrmedonia perforata Champion, 1921, and Hygroptera castanea Motschulsky, 1861. Remarkable cases of colour polymorphism and of sexual dimorphism are discussed. A key to the Zyras sensu strictu species of the Himalaya, India, and Sri Lanka, a key to the species recorded from Thailand, and an updated catalogue of the Zyras sensu strictu species of the Palaearctic and Oriental regions are provided. Additional records of numerous named and several unnamed species are reported. The revised distributions of 37 species are mapped. The subgenus is currently represented in the Palaearctic and Oriental regions by a total of 124 described species. The countries with the greatest diversity are China (46 named species), Malaysia (20), India (20), Indonesia (18), Thailand (13), and Nepal (12). The subgenus is reported from Sulawesi for the first time (five named and two unnamed species). Based on a revision of type material, eleven species are not included in, or excluded from, Zyras sensu strictu, and Zyras unicolor Cameron, 1939 is tentatively moved to Drusilla Leach, 1819.
