    Hallo zusammen!

    An dieser Stelle möchte ich auch auf unsere kommende 50. Internationale Vogelspinnenbörse in Marbach am

    Neckar hinweisen.

    Samstag, 28.10.2017

    “Stadthalle” Marbach am Neckar

    Schillerhöhe 12

    71672 Marbach am Neckar

    Zu unserem 50-Börsen-Jubiläum haben wir wieder ein T-shirt anfertigen lassen und außerdem gibt es dieses

    Mal wieder einen sehr hochkarätigen Vortrag.

    Im Anschluss an die Börse ca. um 15.00 Uhr wird Jorge I. Mendoza Marroquín einen Vortrag über die

    Diversität der Mexikanischen Vogelspinnen halten.

    Wie immer ist der Vortrag für alle Besucher und Aussteller der VS-Börse kostenfrei.

    Es freut sich über euer Kommen:

    MEXICAN TARANTULAS DIVERSITY.

    Mexico has the second highest number of formally described tarantula species worldwide, with 16 genera and 90 species (World Spider Catalog 2017). Despite this, Mexican theraphosid spiders have been poorly studied and it is common to find undescribed species and novel genera (Vol 1999, 2000, 2001; Locht et al. 2005; Locht, 2008; Locht & Medina 2008; Mendoza 2012a, 2012b, 2014a, 2014b, Mendoza et al. 2016; Schmidt 2012; Estrada-Alvarez 2014; Ortiz & Francke 2014; Pérez-Miles & Locht 2003).

    It is common to find in the scientific collections a large number of specimens of tarantulas that are wrong defined or without collection data, which makes it very difficult to establish their taxonomic status. In addition, the taxonomy of this group is extremely complicated which has led to continuous changes and disagreements among the specialists of the group (Schiapelli & Gerschman de Pikelinn 1979; Raven 1985; Smith 1994). However, in recent decades, phylogenetic studies have been published that are helping to clarify the systematics and make the classification of this family more natural (Pérez-Miles et al. 1996, Bertani 2001; Pérez-Miles & Locht 2003, Guadanucci 2013, West & Nunn 2013). This gradual increase in the number of genera and species described shows that a large number of tarantula taxa are expected to be discovered (Pérez-Miles 2000). In the case of Mexican tarantulas there are very few studies done so it is common to find genus and species unknown to science. It is necessary to carry out studies within scientific collections and collection trips to know the diversity of Mexican tarantulas. This is precisely what is being carried out in the National Arachnids Collection (Colección Nacional de Arácnidos) of the Biology Institute of the UNAM, where systematic research projects, using morphological and genetic characters, are being carried out by genus to know their internal relationships, as well as descriptions of new species.

    In Mexico, tarantulas can be found in arid zones, forests, grasslands, jungles and even deep in caves. Some of the latest and more important theraphosid revisions made at the National Collection of Arachids are the revisions of the genus Hemirrhagus, Bonnetina, Crassicrus and Brachypelma. Other remarkable works done are the description of the genus Cotztetlana Mendoza 2012 (Mexican fat legs tarantulas) and the recently described Magnacarina Mendoza, Locht, Kaderka, Medina & Pérez-Miles 2016. During 2009, I collect an arboreal tarantula from Veracruz, which fits with the diagnosis of Psalmopoeus but differs from all known species. This finding confirms the presence of this arboreal genus in Mexico and North America and suggests that it is a new species. The species was the first truly arboreal tarantula to be formally described for México, named as Psalmopoeus victori Mendoza 2014. Actually, we are working with undescribed species of Psalmopoeus, Hemirrhagus, Cotztetlana, Magnacarina, Cardiopelma, Schizopelma and Brachypelma, also with other undescribed genus. In addition, I am implementing strategies for conservation and legal reproduction of Mexican tarantulas.
