MÖLLER ANDERSEN, N.: The Limnogonus and Neogerris of the Old World with character analysis and a reclassification of the Gerrinae (Hemiptera: Gerridae). 1975. 96 pp. SEK 56.

The taxonomic affinities of the two genera are discussed on the basis of a character analysis of selected species of the Gerridae (incl. morphology of the pterothorax, the pre-tarsus, the metasternal scent apparatus, the male genitalia, the gynatrial complex of the female reproductive organs, the ultrastructure of the cuticula, the trichobothria and the metasternal scent ostiole). A number of new characters of taxonomic importance are described. The generic and subgeneric classification of Gerrinae is revised and presented in a checklist and a key.
All species from the Old world are redescribed and -- where possible -- fixed by their types or other authoritative evidence. Keys to species and subspecies are given. Bionomics and distribution are discussed.
