	abstract = {Based on a cladistic analysis, the subfamily Rhinocolinae is redefined to comprise 13 genera and 39 species, of which two genera and eight species remain unnamed. Four new genera and 14 new species are described; one subfamily and one genus are synonymized, and two species are recombined; one lectotype is designated. The subfamily is divided into two groups, one with a Gondwanan distribution comprising four genera in Australia, New Zealand, South America and Africa, and another with Laurasian distribution in the Palaeotropics, the Western Palaerctic and North America comprising nine genera. Twenty-one species develop on host plants in the Rutales, three on Asteraceae, three on Cistaceae and one on Zygophyllaceae. The genus Pistacia (Anacardiaceae) in particular hosts six species whose biology is discussed.},

	abstract = {Abstract. In 2009, the hawthorn psyllid, Cacopsylla melanoneura (F{\"o}rster) (Hemiptera: Psyllidae) was investigated in B{\u a}neasa area within the framework of a pests monitoring program initiated at the Research Development Institute for Plant Protection Bucharest. This psyllid is an important pest for apple orchards in Europe, as it is a vector of the apple proliferation phytoplasma. The overwintered adults colonized the hawthorn and apple as well as the sweet cherry plants in the neighboring of the apple orchards starting with the beginning of March. Egg laying period began in late March (on hawthorn) and early April (on apple). The larvae completed their development on hawthorn and on apple between middle April and June. No eggs or larvae were found on sweet cherry. The adults of the new generation were observed since the beginning of May until June, after that they left the hawthorn and apple plants. Our data indicated that the hawthorn, compared with apple, is mostly preferred as host plant for C. melanoneura, thus the most abundant populations of this insect have been observed on this. Key},
