Interpretive Summary: Sawflies are part of the plant feeding complex of insects that cause millions of dollars of damage each year to agricultural crops, forests, and ornamental plants. Many sawflies are adventive in the United States - accidentally introduced invasive species. It is important to document the exotic fauna to help prevent further introductions. A genus of five species, four of which are new to science, from the Himalayan region are reviewed. They belong to a group that is known to feed on berry crops, and are similar to a genus known in the United States. The species are keyed, described, and illustrated. This will be especially useful to action agencies such as APHIS to prevent the spread of invasive species by commerce.

Technical Abstract: The genus Indostegia, known only from India, includes five species, I. apicicornis Malaise, I. frontata, n. sp., I foveata, n. sp., I. vatsi, n. sp., and I. ecarinata, n. sp. The male of I. apicicornis Malaise is described for the first time. A key is provided for the species.
