A New Darwin Wasp (Hymenoptera: Ichneumonidae) and New Records of Behavioral Manipulation of the Host Spider Leucauge volupis (Araneae: Tetragnathidae).

Some ichneumonid wasps of the Polysphincta group of genera (Hymenoptera: Ichneumonidae: Pimplinae) induce behavioral modifications in their host spiders during a specific moment of their development, resulting in the construction of webs that differ in several aspects from those constructed by unparasitized individuals. In this study, we describe the parasitoid wasp Hymenoepimecis pinheirensis sp. n.
