Phloea subquadrata (Hemiptera, Phloeidae) was observed in two natural reserves of the Brazilian Atlantic forest near Linhares (Espirito Santo). This species exhibits maternal care which is also known for the two other species of the family: Phloea corticata and Phloeophana longirostris. They protect the eggs and also the larvae from predation by covering them with their body. Such behavior is known for other species of Hemiptera, but with some variations. The evolutionary significance of phloeid behaviour is discussed with reference to the behaviour of Hemiptera in general.
A new genus and new species of Cantacaderinae (Heteroptera: Tingidae) is described, Caledoderus monteithi. A key to genera is provided. The phylogenetic relationships among the Cantacaderinae, including this new genus and species, are revisited. The results are congruent with previous studies. However, the Ceratocaderini is a sister group of Carldrakeaninae and not Cantacaderini, even if only weakly supported by the analysis. Therefore, the status of Ceratocaderini and Cantacaderini is maintained, whereas Carldrakeanini stat. nov. is reduced to tribal level and they are all included in the Cantacaderinae., Eric Guilbert., and Obsahuje seznam literatury
Three new species of Tingidae (Tinginae: Tingini) belonging to the New Caledonian endemic genus Nobarnus Distant are described: N. albiceps, N. nigriceps and N. pilosus, N. signatus (Distant) and N. typicus. Distant are redescribed and the status of the genus is discussed and enlarged to accommodate the new species. A table of the main characters distinguishing species and a key to species are given.
