INTRODUCTION

 

There are 44 032 described species of spider in the world, 3905 genera and 110 families.

Based on: (http://research.amnh.org/iz/spiders/catalog/INTRO1.html)

 

Aranea of Ecuador are composed of 43 families, 709 species. The most diverse families so far are the Araneidae (144 species), Oonopidae (89 species), Salticidae (80 species) and the Theridiidae (72 species).

 

The spider fauna of Ecuador is highly underevaluated and we are more than likely to discover a fair number of new species, genus in the years to come.

 

Spiders are easily diagnosed from other arachnids by the presence of a well sclerotized cephalothorax, a separated abdomen, eight legs and the presence of spinnerets at the end of the abdomen.

 

The list is divided by infraorders:

Mygalomorphae and Araneomorphae and is arranged taxonomically .

-Mygalomorphae can be distinguished by their paraxial chelicerae and two pairs of book lungs.

-Araneomorphae have diaxial chelicerae and one pair of book lungs ( if two pairs of book lung then with cribellum).

Aranea de Ecuador se forman de 43 familias, 709 especies. Las familias más diversas hasta ahora son Araneidae (144 especies), Oonopidae (89 especies), Salticidae (80 especies) y Theridiidae (72 species).

 

La fauna de araña de Ecuador es sumamente subvalorada y es más probables que descubra un buen número de nuevas especies, género en los años por venir.

 

Las arañas se diagnostican fácilmente de otros arácnidos por la presencia de un cefalotórax bien esclerotizada, un abdomen separadas, ocho patas y la presencia de hileras al extremo del abdomen.

 

La lista se divide por infraorders:

Mygalomorphae y Araneomorphae y se arregla taxonómicamente.

 

-Mygalomorphae se distinguen por sus quelíceros paraxial y dos pares de pulmones de libro.

-Araneomorphae tienen diaxial quelíceros y un par de pulmones de libro (si dos pares de pulmón de libro entonces con cribellum).
