A new psyllid species, Rhodochlanis suaedicola sp. nov., is described and illustrated from Korea based on adults and fifth instar immatures. Rhodochlanis is reported for the first time from Korea. The new species is associated with Suaeda japonica (Amaranthaceae) growing in saline habitats. Salt marshes in Korea are threatened by sea side developments. It is suggested that these habitats should...

In Cacopsylla myrtilli (W. Wagner, 1947) bisexual populations, all-female populations and populations heavily biased towards females have been described. In the present paper all the available data on the distribution and population sex ratio of C. myrtilli are summarized. New data obtained by the authors are also presented. First records for Russia are described from Siberia and the southern p...

Ctenarytaina bipartita sp.n., associated with Eucalyptus kitsoniana and E. viminalis, is described from the Australian Capital Territory, New South Wales, Tasmania and Victoria. It differs from other described Ctenarytaina species in the paramere which bears a small posterior lobe. Taxonomically relevant morphological details are illustrated and the species is diagnosed from other eucalypt inha...

The small Neotropical genus Mastigimas with five described species is revised.

Another two species are recorded from Brazil and Colombia, respectively, which are not formally described du...

The patterns of sperm formation in sternorrhynchous jumping plant-lice are reviewed. To date information is available for 143 species belonging to 54 genera, 17 subfamilies and seven of the eight psylloid families (only Phacopteronidae is not represented). For the majority of the taxa (116 species, 39 genera, 10 subfamilies and the families Calophyidae, Carsidaridae and Liviidae) the data prese...

Anoeconeossa bundoorensis sp. n. is described from Eucalyptus camaldulensis (Myrtaceae) from southern Victoria in Southeast Australia. It is placed in the A. communis Taylor species-group as the paramere lacks combs of black rods. It differs from other members of the species-group, A. communis and A. bullata Taylor as it lacks an anterobasal expansion on the paramere and from A. unicornuta Tayl...

The association between the ectoparasitic mite, Erythraeus Latreille (Acari: Prostigmata: Parasitengona) and psyllid Russelliana adunca Burckhardt (Hemiptera: Psylloidea) is reported for first time. Larval erythraeid mites are not common on psyllids, therefore this report adds a new host widens distribution of mite in South America.

Cyamophiliopsis is a small genus restricted to the Palaearctic Region and associated with Spiraea spp. (Rosaceae).
