Article
Full-text available
Spider brain and central nervous system (CNS) have remained unexplored, due in part to the difficulty of observing these organs, usually only possible through histological preparations. Recently, internal anatomy studies have been supplemented by the inclusion of X‐ ray micro‐CT. Unmineralized tissue such as the body of invertebrates requires a sta...
Article
Full-text available
Natural history collections include rare and significant taxa that might otherwise be unavailable for comparative studies. However, curators must balance the needs of current and long-term research. Methods of data extraction that minimize the impact on specimens are therefore favored. Micro-CT has the potential to expose new character systems base...
Article
Full-text available
Taxonomic literature contains information about virtually ever known species on earth. in many cases, all that is known about a taxon is contained in this kind of literature, particularly for the most diverse and understudied groups. taxonomic publications in the aggregate have documented a vast amount of specimen data. Among other things, these da...
Article
Full-text available
Citing the specimens used to describe new species or augment existing taxa is integral to the scholarship of taxonomic and related biodiversity-oriented publications. These so-called material citations (Darwin Core Term MaterialCitation), linked to the natural history collections in which they are archived, are the mechanism by which readers may re...
Article
Full-text available
The family Symphytognathidae is reported from Thailand for the first time. Three new species: Anapistula choojaiae sp. nov., Crassignatha seeliam sp. nov., and Crassignatha seedam sp. nov. are described and illustrated. Distribution is expanded and additional morphological data are reported for Patu shiluensis Lin & Li, 2009. Specimens were collect...
Article
Full-text available
The family Hahniidae is reported from Thailand for the first time. The genus Hexamatia gen. nov. and two new species, Hexamatia seekhaow gen. et sp. nov. and Hahnia ngai sp. nov., are described and illustrated. DNA sequences are provided for all the species reported here. The phylogenetic position of the novel genus Hexamatia gen. nov. and its rela...
Article
Full-text available
Bilateral asymmetry in the genitalia is a rare but widely dispersed phenomenon in the animal tree of life. In arthropods, occurrences vary greatly from one group to another and there seems to be no common explanation for all the independent origins. In spiders, genital asymmetry appears to be especially rare. Most known species show almost perfectl...
Article
The genus Wulfila O. Pickard-Cambridge 1895 belongs to the family Anyphaenidae Bertkau, 1878, commonly called ghost spiders. Wulfila is endemic to the Americas and currently has 43 valid species; here we describe five new: Wulfila conchamonile spec. nov., W. xilitlensis spec. nov., W. luisi spec. nov., W. unguis spec. nov. and W. phantasma spec. no...

Bilateral asymmetry in the genitalia is a rare but widely dispersed phenomenon in the animal tree of life. In arthropods, occurrences vary greatly from one group to another and there seems to be no common explanation for all the independent origins. In spiders, genital asymmetry appears to be especially rare. Few examples have been studied in detai...
Article
Full-text available
Traditional taxonomic publications have served as a biological data repository accumulating vast amounts of data on species diversity, geographical and temporal distributions, ecological interactions, taxonomic relations, among many other types of information. However, the fragmented nature of taxonomic literature has made this data difficult to ac...
Article
Full-text available
The diversity of araneomorph spiders in an ecoturistic tropical forest remnant of approximately 40ha is described. A 1-ha plot with homogeneous vegetation was established. Six sampling methods covered all microhabitats, except tree canopy. Four expeditions were conducted from August 2011 to June 2012. In a total of 485 samples, 4,118 adult specimen...
Article
Full-text available
Three new species of the spider genus Trachelas L. Koch, 1872 are described and included in the speciosus group based on the following features: embolus as a separate sclerite from the tegulum with no basal coils, legs with a conspicuous fringe of long trichobothria and narrow copulatory ducts coiled irregularly. The new species described are: T. c...

Question
I need to collect and export live and alcohol fixed spider specimens for my research in these countries. Unfortunately I have not been able to find any explicit information on this regard. Does anyone have this information or could point me in the right direction?
Thanks a lot!
