WMegaloptera is an order of insects. It contains the alderflies, dobsonflies and fishflies, and there are about 300 known species.
WAlderflies are megalopteran insects of the family Sialidae. They are closely related to the dobsonflies and fishflies as well as to the prehistoric Euchauliodidae. All living alderflies – about 66 species all together – are part of the subfamily Sialinae, which contains between one and seven extant genera according to different scientists' views.
WThe family Corydalidae contains the megalopterous insects known as dobsonflies and fishflies. Making up about one dozen genera, they occur primarily throughout the Northern Hemisphere, both temperate and tropical, and South America.
WNeoneuromus is a genus of dobsonfly endemic to the Indomalayan realm with 13 species. The larvae breed in montane streams. Adults are large with a forewing of 43 to 68 mm length and the body is yellow to red or brown with black marks on the head and pronotum. The wings are marked in dark patterning in the membrane and along the veins. They are closely related to Nevromus from which they are separated by the attenuation of the 9th sternum with an incised tip.
WNevromus is a genus in the dobsonfly or Corydalidae family of Megalopteran insects. They are found in Asia and are among the few Asian Corydalines that are found on islands including Borneo, Java and Sumatra.
