Visual acuity trade-offs and microhabitat driven adaptation of searching behaviour in psyllids (Hemiptera: Psylloidea: Aphalaridae)

Visual acuity trade-offs and microhabitat-driven adaptation of searching behaviour in psyllids (Hemiptera: Psylloidea: Aphalaridae).

Insects have evolved morphological and physiological adaptations in response to selection pressures inherent to their ecology. Consequently, visual performance and acuity often significantly vary between different insect species. Whilst psychophysics has allowed for the accurate determination of visual acuity for some Lepidoptera and Hymenoptera, very little is known about other insect taxa tha...

Rhodochlanis suaedicola sp. nov. (Hemiptera: Sternorrhyncha: Psylloidea: Aphalaridae) associated with Suaeda japonica (Amaranthaceae) from Korea.

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...

Making the most of your host: the Metrosideros-feeding psyllids (Hemiptera, Psylloidea) of the Hawaiian Islands

The Hawaiian psyllids (Psylloidea, Triozidae) feeding on Metrosideros (Myrtaceae) constitute a remarkable radiation of more than 35 species. This monophyletic group has diversified on a single, highly polymorphic host plant species, Metrosideros polymorpha. Eleven Metrosideros-feeding species included in the Insects of Hawaii by Zimmerman are redescribed, and an additional 25 new species are de...

A revision of Chinese pear psyllids (Hemiptera: Psylloidea) associated with Pyrus ussuriensis

The Chinese pear psyllids, Cacopsylla spp., associated with Pyrus ussuriensis are reviewed. Three new species, C. accincta sp. n., C. burckhardti sp. n., and C. cinereosignata sp. n., are described. Cacopsylla liaoli (Yang & Li), C. qiuzili Li, C. maculatili Li and C. chinensis (Yang & Li) are redescribed. A key to the adults of the seven species and a key to nymphs of three species are given.
