Megaloptera

thumb|Corydalus cornutus - MHNT

Alderflies 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 nine extant genera.

The family Corydalidae contains the megalopterous insects known as dobsonflies and fishflies. Making up about three dozen genera, they occur primarily throughout North America, both temperate and tropical, South America, Australia, New Zealand, Africa (particularly South Africa) and Asia.

Neoneuromus 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 ninth sternum with an incised tip.

Nevromus 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.

Parachauliodes is a genus of fishfly in the family Corydalidae. They are present throughout Eastern Asia, likely originating on the Korean peninsula before dispersing to the Japanese archipelago 15 mya.
