“…2I-L, 12A-D). The male palp is slightly similar to that of T. caaguara Rodrigues & Ott 2005b, T. esmeraldas Dupérré & Tapia 2017, T. circuloargenteum Wunderlich 1976, and T. taiwanica Zhang, Zhu & Tso 2006 in lacking a conductor projection but distinguished by the presence of two parallel embolic apophyses. The female genitalia of the new species is slightly similar to that of T. chiripa Rodrigues & Ott 2005a and T. taiwanica in lacking sclerotized processes, and the edge of the genital plate posteriorly curved, distinguished by angular lateral corners of genital plate, with the genitalia longer than the width (distance between posterior edge of genital plate and anterior edge of spermathecae is longer than the width of genital plate) in the new species (Figs.…”

“…This suggested that the ability to internalize into cells of micelles could be the source of hepatic lesions, as QCT‐M can enter deep into cells and exert the interference with its functions. Additionally to this blood stagnation, cytoplasmic vacuolization that occurred might be linked to either a reduction in liver glycogen or venom accumulation in the hepatocytes (or a combination of these two phenomena) 63 . As a result from these, QCT and QCT‐M at higher doses (400 and 450 μg/L) experienced vacuolization that may alter liver function.…”

Quercetin has been studied extensively with drug delivery systems due to the drug's needs to improve in solubility, but usually the systems are complicated, evading the practical aspects and potential applications. This problem is expected to be solved using the simplistic micelles, in combination with the materials mPEG and cholesterol to gain advantages from the nano‐size, while increasing its overall stability and drug releasing. In this study PEGylated‐cholesterol micelles were prepared by co‐solvent method in 4 different drug‐polymer ratios, which were then characterized by physical–chemical, in vitro analyses and emphasized on the in vivo cytotoxicity test by H&E staining histological assay on Danio rerio model. The results show promising features of nano‐micelles as a passive drug delivery system in size, CMC value, and prolonged drug releasing profile. Compared to free QCT, the micelles‐loaded system exhibited significantly higher toxicity in vitro, which were also demonstrated in in vivo models, where the drug‐loaded micellar systems posed mild tissue changes, while blank micelles and free quercetin were almost harmless to the animals. The results had concluded that effective delivering of micellar system does not require advanced material‐composition, rather a throughout understanding of the interactions of nano‐properties and the materials with bio‐systems.

“…Mysmenidae, Theridiosomatidae and Symphytognathidae generic rank identification were relatively easy thanks to contributions to the taxonomy of these families (Coddington 1986;Gertsch 1960Gertsch , 1971Lopardo & Hormiga 2015;Forster & Platnick 1977); however, their knowledge in Neotropical regions have presented slow progress where only species descriptions for specific areas are available (Brescovit et al 2004;Dupérré & Tapia 2017;Rheims & Brescovit 2003;Rodrigues & Ott 2005a, 2005b. For Theridiosomatidae, both Epilineutes Coddington, 1986 species and one Theridiosoma O. Pickard-Cambridge are probably new taxa.…”

Spider community inventories have relatively well-established standardized collecting protocols. Such protocols set rules for the orderly acquisition of samples to estimate community parameters and to establish comparisons between areas. These methods have been tested worldwide, providing useful data for inventory planning and optimal sampling allocation efforts. The taxonomic counterpart of biodiversity inventories has received considerably less attention. Species lists and their relative abundances are the only link between the community parameters resulting from a biotic inventory and the biology of the species that live there. However, this connection is lost or speculative at best for species only partially identified (e. g., to genus but not to species). This link is particularly important for diverse tropical regions were many taxa are undescribed or little known such as spiders. One approach to this problem has been the development of biodiversity inventory websites that document the morphology of the species with digital images organized as standard views. Their main contributions are the dissemination of phenotypic data for species difficult to identify or new with the assignment of species codes, allowing species comparisons between areas regardless of their taxonomic status. The present paper describes a protocol to produce these websites almost automatically. This protocol was successfully applied to 237 species from a tropical primary forest in Mexico. The time and infrastructure required for the documentation of these species are discussed. Taxonomic information in terms of identification challenges, possible new species, and potential nomenclatural issues is described. In addition, the conventional community parameters (e. g., inventory completeness, species richness estimations, sampling intensity) are also calculated and compared through time and between methods. An optimized version for sampling allocation effort per season is presented and compared with protocols optimized for other tropical forests.
