The South American genus Lagideus (Hymenoptera: Pergidae: Syzygoniinae), a supplement. Zootaxa. 3413:1-18. Interpretive Summary: The caterpillar-like pergid sawfly larvae are plant defoliators that can cause great economic and environmental damage to agricultural crops, forests, and ornamentals. A group of species that may feed on economically important ornamental plants was previously revised, but additional specimens have been discovered and examined. This research describes six new sawfly species, describes previously unknown females of two species, presents new distribution data, and provides a key to species and illustrations. This information will be of use to scientists or quarantine officials attempting to identify species that are potential invasive species to the United States. Technical Abstract: Six new species of the Neotropical pergid genus Lagideus are described and illustrated: Lagideus boyaca, L. magdalena, L. schmidti, and L. flavus from Colombia and L. tapanti and L. isidro from Costa Rica. Lagideus romius Smith is newly recorded from Colombia and the female lancet is illustrated. Females are described for the first time for Lagideus longicus Smith from Costa Rica and L. albitarsis Malaise from southeastern Brazil, Uruguay, and Argentina. |
