Ametastegia is a genus of common sawflies in the family Tenthredinidae. There are about 16 described species in Ametastegia. [1] [2] [3] [4]
These 16 species belong to the genus Ametastegia:
Sawflies are the insects of the suborder Symphyta within the order Hymenoptera, alongside ants, bees, and wasps. The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay their eggs. The name is associated especially with the Tenthredinoidea, by far the largest superfamily in the suborder, with about 7,000 known species; in the entire suborder, there are 8,000 described species in more than 800 genera. Symphyta is paraphyletic, consisting of several basal groups within the order Hymenoptera, each one rooted inside the previous group, ending with the Apocrita which are not sawflies.
The Tenthredinoidea are the dominant superfamily of sawflies within the Symphyta, containing some 8,400 species worldwide, primarily in the family Tenthredinidae. All known larvae are phytophagous, and a number are considered pests.
Tenthredinidae is the largest family of sawflies, with well over 7,500 species worldwide, divided into 430 genera. Larvae are herbivores and typically feed on the foliage of trees and shrubs, with occasional exceptions that are leaf miners, stem borers, or gall makers. The larvae of externally feeding species resemble small caterpillars. As with all hymenopterans, common sawflies undergo complete metamorphosis.
Nematinae is a subfamily of sawflies belonging to the family Tenthredinidae. It contains over 1250 described species in ~40 genera. Members of this subfamily feed on a wide range of plants and employ a wide range of feeding habits, both internally and externally, on their host plants.
Allantinae is a subfamily of sawflies in the family Tenthredinidae, and the largest subfamily of that family, with about 110 genera. The subfamily is considered to consist of five to six tribes, and are medium to large sawflies.
Arge is a genus of sawflies belonging to the family Argidae subfamily Arginae.
Macrophya is a genus of sawfly.
Monostegia is a genus of sawfly. The authority is based on the description by Achille Costa and Oronzio Costa, although earlier work grants this to Fabricius 1798., though the commonest species, M. abdominalis, bears the authority of Fabricius.
Tenthredininae are a subfamily of sawflies within the family Tenthredinidae, the largest sawfly family. It consists of about 50 genera, including the type genus Tenthredo. It also includes most of the larger and more colourful members of the family. Some authorities divide these into tribes. Distribution is Northern Hemisphere and holarctic.
Allantus is a genus of sawflies of the family Tenthredinidae.
Endelomyia is a genus of common sawflies in the family Tenthredinidae. There are at least two described species in Endelomyia.
Eriocampa is a genus of common sawflies in the family Tenthredinidae. There are about ten described species in Eriocampa.
Monsoma is a genus of common sawflies in the family Tenthredinidae. There are at least two described species in Monsoma.
Pachyprotasis is a genus of common sawflies in the family Tenthredinidae. There are at least 40 described species in Pachyprotasis.
Periclista is a genus of common sawflies in the family Tenthredinidae. There are at least 20 described species in Periclista.
Rhogogaster viridis is a species of common sawfly in the family Tenthredinidae.
Stethomostus is a genus of common sawflies in the family Tenthredinidae. There are at least two described species in Stethomostus.
Fenusa is a genus of common sawflies in the family Tenthredinidae. There are about 11 described species in Fenusa.
Tethida is a genus of common sawflies in the family Tenthredinidae. There is one described species in Tethida, T. barda.
Macremphytus is a genus of common sawflies in the family Tenthredinidae. There are at least four described species in Macremphytus.
