It was previously reported as undescribed based on immatures. Cyrtophora citricola is native to the Mediterranean, tropical African and southern Asian regions. It was introduced into Colombia about 1996, where it is rapidly spreading. Species in the genus Cyrtophora are known as 'tentweb weavers' because the horizontal orbs with much three-dimensional supporting structure can encompass the crowns of shrubs and trees (Dr. G.B. Edwards).
