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
10:00 bis 15:00 Uhr
Anmeldung für Aussteller Sonntag, 01.10.2017 ausschließlich ab 12:00 Uhr über unsere Website http://www.vogelspinnen-ig.com
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:
Die Vogelspinnen-IG Stuttgart/Ludwigsburg e.V.

Arachnida
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.
