Hydrosalpingidae
Karl KjerIntroduction
The family contains only a single species Hydrosalpinx sericea described by Barnard (1934). He placed the species only within the “Aequipalpia” in the “neighbourhood of Molannidae- Beraeidae,” but not within a specific family. Fischer (1970) had the genus listed under Helicopsychidae, but noted Scott’s (1967) opinion that it may belong to the Beraeidae. It was not until 1985 that a new family, Hydrosalpingidae, was established for the genus (Scott 1985), which was more fully diagnosed and described some years later (Scott 1993). The species is endemic to the western and southwestern Cape Province of South Africa. Once common in cool acidic mountain streams, the species is now considered rare, possibly due to predation by introduced trout. Larvae feed on algae and detritus. From Holzenthal et al. (2007a).Characteristics
The tubular cases of Hydrosalpynx have a slightly flared anterior end and are made entirely of golden-brown silk. The discarded cases are often occupied by species of Athripsodes (Leptoceridae). Adults are medium-sized, densely hairy, golden brown caddisflies. Males have unusually long and slender maxillary and labial palps. From Holzenthal et al. (2007a).Discussion of Phylogenetic Relationships
The sister taxon relationship between Hydrosalpingidae and Petrothrincidae were strongly supported in Holzenthal et al. (2007b).References
