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. The former genus
Sinochauliodes was found to be a
synonym of
Parachauliodes. 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. Male
Parachauliodes produce a gelatinous
spermatophore with spherical bundles of
sperm. 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. 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. == Taxonomy ==
