Colonial Isoxya manangona n. sp. from Andasibe, Madagascar. (a) A part of a colony with 79 spiders in 41 webs (image shows 23 webs). (b) A detail from another colony where females are in their individual webs (image shows 14 of the 16 webs in the colony) while males hang on line in between webs (image shows 12 males). (c) A detail of another colony showing male leks. These males showed no overt intrasexual aggression that would be typical of solitary spiders. (Insect Systematics and Diversity)
