摘要:

A population ofElectrogenafrom central Apennine (Italy), previously attributed toE. later‐alis(Curtis) proved to be a new species after electrophoretic analysis. Imagines of the new species, namedE. lunarissp. n. differ fromE. lateralisonly by body and wing colouration. Larvae can be identified by numerical methods. Electrophoresis indicated three loci (Aldh, Gdh, Mpi) that are diagnostic between the syntopic populations ofE. lunarisandE. lateralisand the allele frequencies of three other loci (Est‐2, Mdh‐1, Pgm) were statistically different between the two species.

摘要:

Simothraulopsis surinamensisDemoulin, 1966, a synonym ofSimothraulopsis demerara(Traver, 1947) new synonym, is redescribed from associated adults and nymphs from French Guiana and Surinam, with additional records from northern Brazil and Venezuela. The type speciesof SimothraulopsisbecomesS. demeraranew combination. We confirm that the presumed nymph ofHomothraulusdescribed by Traver (1960) is correctly associated with imagines.

摘要:

Arctopsyche mesogonasp.n.,A. vietnamensissp.n. andA. cervinatasp.n. are newly described from the Fan Si Pan Mountain Range of North Vietnam. These species belong to thecompasita—group, which is a Palaearctic faunal element in an area which is conventionally regarded as part of the Oriental Region. Phylogenetic relationships of the species are examined.

摘要:

The morphology and chaetotaxy of the three larval instars of the genusCalobiusWollaston, 1854 are described and illustrated following the setal pattern ofCalobius quadricollisMulsant, 1844. The study revealed several characters on the cephalic capsule, head appendages, and the thoracic and abdominal segments that can be used to restoreCalobiusas a valid genus. A table showing twenty different features between the larvae of the genusCalobiusand the genusOchthebiusLeach, 1815 is provided.
