Corydalus is a genus of large flying insects in the Corydalidae family, commonly known as dobsonflies. They are endemic to North, Central and South America and there are about 40 known species. Members of the genus have wing lengths of up to 85 millimetres. They are sexually dimorphic, with the males having large mandibles used to grasp the females during mating while the females have smaller jaws. The larvae are known as hellgrammites and are aquatic predators.[1][2]
Diagnosis
[edit]Adults
[edit]The adults of this genus can be separated from all other Neotropical dobsonflies by having four palpomeres (palpal segments) instead of three, though there are two South American species with only a partial subdivision in the last palpomere. Species in the genus vary much in size and may have a forewing length of 33.5–85.3 mm (1.32–3.36 in). They also show a lot of intraspecific variation in size.[3]
Larvae
[edit]The larvae are similar to larval Platyneuromus, as both have mucle attachment scars on the head and thoracic nota. Once these are confirmed, the Platyneuromus and Corydalus can be separated based on small details found below.[3]
Corydalus: Abdominal setae are erect, dark macrosetae which are either striated, inflated, and seemingly closed at the apex OR elongated and striated OR elongated and completely smooth. Often with short, blunt submental projections that do not go past the anterior margin of the mental plates, but some South American species have similar submental projections as Platyneuromus.[3]
Platyneuromus: Abdominal setae are clear and either tubular and widened with an open apical portion OR thin, smooth and with an inconspicuous apical hole. Always with long and pointed submental projections that go past the anterior margin of the mental plates.[3]
Etymology
[edit]Corydalus is a transliteration from the Greek κορδαλος (korúdalos)[4] meaning a crested lark or the flower, larkspur, apparently related to Greek corys (κορυς) a helmet crest.[5] The name probably refers to the long mandibles of the male which might be considered to resemble the crest of a lark, or perhaps, the decorative crests of a helmet.[2]
