I am really wondering how bayucca could call this one Gracilis...

There are currently approximately 31 species of Micrathena for Central America alone. I love how people typically say M.sagittata or M.gracilis, but what about all the rest??!? This one seems most like Micrathena zilchi, but not recorded south of Honduras/El Salvador, so is quite an expansion of range into Costa Rica.

Cool spider! Hope you can get the correct ID up.

I think it is the other one: Micrathena gracilis, female. Sagittata has usually 2 very prominent spikes.

Alejo si es una M. sagittata
Compárela con esta: http://bugguide.net/node/view/6080
Pero estoy bastante seguro de que si es

Nacho tenes razon y creo que es este dale una ojeada y me das tu opinion... Arrow-shaped Micrathena - Micrathena sagittata

Mil Gracias

Parece una Micrathena sagitta, pero no estoy seguro. Lo que si es seguro es que es de esa familia
