摘要:
The psyllid‐fauna of temperate and subantarctic South America comprises members of three families: Calophyidae, Triozidae and Psyllidae. Three subfamilies of the Psyllidae are revised in this paper: the Aphalarinae are represented by two species in two genera, one of which develops on Aquifoliaceae; the Rhinocolinae are represented by two congeneric species on Anacardiaceae while the Aphalaroidinae contain 38 species in seven genera trophically linked to the Compositae, Euphorbiaceae, Leguminosae, Myzodendraceae, Rhamnaceae, Solanaceae and Zygophyllaceae. The family Psyllidae (= Aphalaridaesyn. nov., =Spondyliaspididaesyn. nov.) and the constituent subfamily Aphalaroidinae (= Arepuninaesyn nov., = Ciriacreminae auct. pp) are redefined. Three genera and 30 species are described as new and two new generic, two new specific synonyms, and five new combinations are proposed. Information on larvae and host plant relationships is also given. Lectotypes are designated for eight species and a type‐species is fixed for one genus. Keys are provided for the identification to spec

摘要:
The peritremes of the British intertidal Gamasina are structurally similar to those described for species occurring in soil and leaf litter, the highly elaborate peritreme plastrons present in species occurring in low oxygen tension environments are not typical of the fauna. It is shown that elaborate peritremes can form effective gas gills if an airfilm is supported by the peritrematic slit; however, if the airfilm is supported by the micropapillae on the floor of the peritreme, then the respiratory efficiency of the gas gilhbecomes comparable with that of elaborate peritreme plastrons. Evidence is presented reinforcing the theory that the plastron is supported by the micropapillae. The absence of elaborate respiratory peritreme plastrons among the intertidal Gamasina suggests that these mites are preadapted to respiration during tidal inundation. Other preadaptations include the distal parabolic shape of the micropapillae, however in the plastron forming species the micropapillae are shorter and basally thicker to prevent bending under pressure Developmental trends within the peritremes, with respect to plastron formation are discussed.
