Parachauliodes is a genus of fishfly in the family Corydalidae. [1] They are present throughout Eastern Asia, likely originating on the Korean peninsula before dispersing to the Japanese archipelago 15 mya. [2]
Parachauliodes are differentiated from other genera of fishflies by the presence of bi-lobed ectoproct in males and usually having serrated antenna in both sexes. [3] The genus Sinochauliodes was found to be synonymous to a group within Parachauliodes. [2]
Larvae have a pair of respiratory tubes on their dorsal side to enable aerial respiration in poorly oxygenated water. [4] Larvae climb out of the water during the night following rain, and P. continentalis dig a bowl-like pit as a pupal chamber. In some species, males mature faster and leave the water earlier to ensure greater mating success. [5] Male Parachauliodes produce a gelatinous spermatophore with spherical bundles of sperm. [6] The volume of the spermatophore ranges within the genus being large enough to prevent remating by females in P. japonicus white being smaller and decreasing in size more slowly in P. continentalis. [7] Adult Megaloptera have been described as dispelling meconial fluids from their anus as a potential defense mechanism, and Parachauliodes produce a much larger volume than other genera. [8]
Parachauliodes contains the following species: [9]
Aquatic insects or water insects live some portion of their life cycle in the water. They feed in the same ways as other insects. Some diving insects, such as predatory diving beetles, can hunt for food underwater where land-living insects cannot compete.
A spermatophore or sperm ampulla is a capsule or mass containing spermatozoa created by males of various animal species, especially salamanders and arthropods, and transferred in entirety to the female's ovipore during reproduction. Spermatophores may additionally contain nourishment for the female, in which case it is called a nuptial gift, as in the instance of bush crickets. In the case of the toxic moth Utetheisa ornatrix, the spermatophore includes sperm, nutrients, and pyrrolizidine alkaloids which prevent predation because it is poisonous to most organisms. However, in some species such as the Edith's checkerspot butterfly, the "gift" provides little nutrient value. The weight of the spermatophore transferred at mating has little effect on female reproductive output.
Megaloptera is an order of insects. It contains the alderflies, dobsonflies and fishflies, and there are about 300 known species.
Dobsonflies are a subfamily of insects, Corydalinae, part of the Megalopteran family Corydalidae. The larvae are aquatic, living in streams, and the adults are often found along streams as well. The nine genera of dobsonflies are distributed in the Americas, Asia, and South Africa.
Fishflies are members of the subfamily Chauliodinae, belonging to the megalopteran family Corydalidae. They are most easily distinguished from their closest relatives, dobsonflies, by the jaws (mandibles) and antennae. In contrast to the large jaws of dobsonflies, fishfly mandibles are not particularly noticeable or distinctive, and the males have feathery antennae similar to many large moths. Chauliodes pectinicornis, the "summer fishfly", is a well-known species in North America.
The 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.
Sialis lutaria, common name alderfly, is a species of alderfly belonging to the order Megaloptera family Sialidae.
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 between one and seven extant genera according to different scientists' views.
Chauliodes pectinicornis known as Summer fishfly, is a species of fishfly from North America.
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.
Nevromus austroindicus is a species of dobsonfly found in the Western Ghats of India. It is one of two species of the family Corydalidae found in southern India, the other being Neurhermes maculifera. It was formally described in 2012 on the basis of specimens from the Karnataka Western Ghats of Kottigehara with some specimens also obtained from near Sampaje. They are closely related to species found in mainland China.
Nigronia serricornis has many common names including hellgrammites or fishflies or saw-combed fishflies. The genus Nigronia has one other North American member N. fasciatus and South American which lives in much of the same territory and is quite similar in all regards. They are holometabolous insects with an aquatic larval stage. N. serricornis is a common inhabitant of woodland streams in North America and they are often the largest insect predator found in 2nd and 3rd order streams. The larvae are a sit-and -wait ambush predators that feed on a large variety of invertebrates. Studies have shown that N. serricornis has a varying diet throughout the seasons.
Archichauliodes diversus is an insect in the subfamily Chauliodinae - the fishflies, though it is often referred to as the New Zealand dobsonfly, despite not being a true dobsonfly. In its larval form it is commonly known by the name toe-biter, and its Māori name is puene. The species is native to New Zealand. Although there are many other species of fishfly in other parts of the world, Archichauliodes diversus is the only species of fishfly in New Zealand.
Neohermes concolor is a species of fishfly in the family Corydalidae. It is found in North America.
Neohermes filicornis is a species of fishfly in the family Corydalidae. It is found in North America.
Acanthacorydalis fruhstorferi is a species of dobsonfly native to Vietnam and China. It holds the title of largest aquatic insect by wingspan according to the Guinness Book of World Records at 21.6 cm. The title formerly belonged to the Brazilian damselfly Microstigma rotundatum.
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.
Taeniochauliodes is a genus of fishflies in the family Corydalidae.
Protohermes is a genus of dobsonflies in the family Corydalidae. Protohermes is the most specious and widely distributed genus within Megaloptera, but up to 85% of species are restricted to small endemic areas in Asia. This endemism may be a result of an association with high elevation and high slope streams in Northern Vietnam and China.
Neurhermes is a genus of dobsonflies in the family Corydalidae.
