This is a ground spider (family Gnaphosidae) of species Pterotricha lentiginosa (thanks Dr. Maria Chatzaki, a Cretan arachnologist, for the ID), which happens to be the most abundant species of Gnaphosidae on Crete. Its body meassured about 10-15mm and it was found hidding in a pile of rocks. Ground spiders lack a prey-capture web and generally run prey down on the surface.

The tell-tale feature of spiders belonging to subfamily Gnaphosinae are the anterior spinners which are long, cylindrical and separated from each other by the diameter of one of them, as is evident in this photo.

You can also see another photo of the same spider that I have uploaded to Flickr.

Hola Stavros... una agradable presentación de esta especie de araña.
Me gusta el punto de vista captado con buena agudeza y composición.
Personalmente creo que ha fallada la iluminación para mostrar mayores detalles del animal, ya sea por la falta del uso del flash o la inadecuada compensación de exposición (+/- 2) que permite graduar la entrada de luz al sensor de tu Canon... he tenido ese modelo de cámara para uso personal y conozco la calidad de imagen que captura.
Buen intento... espero continuar viendo nuevos trabajos tuyos en el futuro.
Un cordial saludo desde Buenos Aires... Ricardo

Kalimera Stavros,
you had the courage to present the pic with a "dull" spider on a dull background.
But you were right and you did it very well! This is a really interesting spider that we will rarely ever see. Thanks for the detailed commentary.
Cheers, Dietrich
