Micrathena gracilis

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.

Con gusto, Alejo

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

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

Beautiful!
