Epiphytic Bromeliads

A survey of the camerobiid mites living on epiphytic bromeliads and the forest floor of a Mexican tropical dry forest was carried out. We found three new species of the genus Neophyllobius, which are described in this paper; the first two, namely N. cibyci sp. nov. and N. tepoztlanensis sp. nov., were both found inhabiting bromeliads (Tillandsia spp.) and living on two tree species (Quercus obtusata and Sapium macrocarpum); the third, N. tescalicola sp. nov., was found in soil and litter under Q. obtusata. These three new species can be differentiated from other species in the genus by a combination of morphological characters in adult females, mainly those setae on femora and genua I. The idiosoma and leg setal ontogeny of a camerobiid mite is presented for the first time in this paper, illustrating chaetotaxic notations and their relative positions in N. cibyci sp. nov. larva, protonymph and adults (female and male), and establishing setal homologies among instars. Setal homology with other species in the cohort Raphignathina is briefly discussed. Additionally, a compilation and an identification key to all known species of camerobiid mites in Mexico is provided.

AbstractIn recent years, no less than five new species of early turtles have been described worldwide. Among them are three new turtles from Middle Jurassic deposits that partially fill a previous temporal and morphological gap in our knowledge of the early evolution of these shelled amniotes: Heckerochelys romani, Condorchelys antiqua and Eileanchelys waldmani. For the first time, the phylogenetic position of these three new species is tested in the context of the two presently competing cladistic models of turtle evolution. The addition of these taxa to each matrix does not favour or alter any of the two opposed hypotheses. However, it is demonstrated here that, by documenting yet unknown stages in the evolution of several morphological structures, these three species give stronger support to the model of an extended phylogenetic stem for turtles. These new lines of evidence include the structure of the vomer, the position of the aditus canalis stapedio-temporalis and of the posterior opening of the canalis cavernosus, and the morphology of the processus interfenestralis of the opisthotic.Recent discoveries also reinvigorate the debate about the palaeoecology of early turtles. Whereas simple morphological characters (e.g., shell fontanelle, ligamentous bridge, flattened carapace) can be misleading, forelimb proportions and shell bone histology have led to the conclusion that most stem turtles (i.e., Proganochelys quenstedti, Palaeochersis talampayensis, Proterochersis robusta, Kayentachelys aprix and meiolaniids) were terrestrial forms. At least two out of the five recently described early turtles have been convincingly interpreted as having aquatic habits: Odontochelys semitestacea and Eileanchelys waldmani. More investigation is needed, but this will undoubtedly trigger further debate on the primitive ecology of turtles and on the origin of aquatic habits in testudines (i.e., the crown-group), respectively.

The Mediterranean specimens of the genus Microporella collected from shallow water habitats during several surveys and cruises undertaken mostly off the Italian coast are revised. As a result of the disentanglement of the M. ciliata complex and the examination of new material, three new species, M. bicollarissp. nov., M. ichnusaesp. nov., and M. pachyspinasp. nov., are described from submarine caves or associated with seagrasses and algae. An additional species Microporella sp. A, distinct by its finely reticulate ascopore, is described but left in open nomenclature owing to the limitations of a single infertile fragment. After examination of all available material, based on their identical zooidal morphology, the genus Diporula is regarded as junior synonym of Microporella and the combination Microporella verrucosa is resurrected as first suggested by Neviani in 1896. Fenestrulina joannae is also reassigned to Microporella. The availability of a large number of colonies of the above-mentioned and other species already well known from the area (i.e., M. appendiculata, M. ciliata, and M. modesta), allowed the assessment of their high intraspecific variability as well as the observation, for the first time, of some morphological characters including ancestrulae, early astogeny, and kenozooids. Finally, M. modesta, in spite of M. ciliata as defined by the neotype selected by Kukliński & Taylor in 2008, appears to be the commonest species in the basin.

The genus Australiseiulus Muma contains the most holotrichous members of the mite family Phytoseiidae, and is the only known endemic phytoseiid genus in Australia. The revised and redefined genus contains five species in 2 species-groups, differentiated by the position of podonotal setae z6 and the number of teeth on the movable cheliceral digit. The australicus-group contains A. australicus (Womersley) and A. angophorae (Schicha); the goondi-group contains A. goondi, sp. nov., A. dewi, sp. nov. and A. poplar, sp. nov. Both species-groups are defined, all species are diagnosed, a key to adult females and detailed descriptions of the three new species and A. australicus are provided. In addition, immatures of A. australicus and A. goondi are described for the first time.

In this paper we revise the species of Sicarius (Araneae: Sicariidae) from the Brazilian Caatinga, the largest tropical dry forest nucleus in the world. We redescribe, designate a neotype and provide new records for Sicarius tropicus (Mello- Leitão, 1936), the only species previously known from the region, and describe three new species: S. cariri n. sp., S. diadorim n. sp. and S. ornatus n. sp. We report high intraspecific variation in the genitalic morphology of these species, especially in females. We also provide anecdotal observations on natural history and behavior of these species, including diet, mating behavior and clutch size. We include an identification key for Brazilian Caatinga species of Sicarius.

The genus Myopias Roger, 1861 is distributed in the Australian, Oceanian, Oriental and southern Sino-Japanese realms. Currently 40 valid species and three subspecies have been described, but none have ever been recorded for Thailand. Here we review the species of Thailand, recognizing seven in total. Four are new records of previously described species: Myopias bidens (Emery, 1900), M. crawleyi (Donisthorpe, 1941), M. maligna punctigera (Emery, 1900), and M. mandibularis (Crawley, 1924). Three new species are described: Myopias minima sp. nov. from southern Thailand, M. sakaeratensis sp. nov. from eastern Thailand and M. sonthichaiae sp. nov. from northern and western Thailand. The queen caste of M. mandibularis is described here for the first time and additional descriptions of other species are provided. All these species were found to nest in rotten wood on the forest floor.

Four species of Mycena possessing a colored lamellar are reported. Of these, Mycena entolomoides is described as new and is distinguished by an incarnate color of the whole lamellae, and M. citrinomarginata, M. purpureofusca, and M. strobilinoidea are recorded for the first time in China. A complete description, drawings and photographs of the morphological characters of M. entolomoides sp. nov. are accompanied by comparisons with closely related taxa. The three species newly recorded in China are considered in agreement with those species in Europe and North America. Phylogenetic analysis based on ITS sequences showed that M. entolomoides sp. nov. forms a monophyletic clade, well supported by maximum likelihood and Bayesian inference.

On the contrary, it is generally accepted that crown-group turtles are ancestrally aquatic. Among the five recently described stem-group turtles, Odontochelys semitestacea and Eileanchelys waldmani have been convincingly interpreted as having aquatic habits, which suggests that basal turtles were ecologically diverse. More investigation is needed, but this will undoubtedly trigger further debate on the primitive ecology of turtles and on the origin of aquatic habits in Testudines (i.e., the crown-group), respectively.
