Dispersal is a central process to almost all species on earth, as it connects spatially structured populations and thereby increases population persistence. Dispersal is subject to (rapid) evolution and local patch extinctions are an important selective force in this context. In contrast to the randomly distributed local extinctions considered in most theoretical studies, habitat fragmentation ...

Neocunaxoides promatae sp. nov., Bonzia flechtmanni sp. nov. and Dactyloscirus multiscutus sp. nov. are described from soil and leaf litter in Atlantic rainforest and Atlantic Araucaria forest in natural environments in São Francisco de Paula municipality, Rio Grande do Sul State, Brazil.

Koch (Acari: Tetranychidae) is a major pest mite infesting vegetables and horticultural ornamental agronomic crops in Egypt. In biological control strategies, natural enemies were applied to maintain TSSM population below the level where damage occurs for an extended period of time besides utilizing acaricides critical situation as quick practice avoid deleterious damage. This study evaluated p...

Three new species of eriophyoid mites from Xinjiang Uygur Autonomous Region, China, are described and illustrated. They are Paracolomerusgonglius sp. n. and Phyllocoptrutabeggerianae sp. n. collected on Rosabeggeriana Schrenk ex Fisch. & C. A. Mey.

Three new species of chigger mites, Eutrombicula cubensis sp. n. and E. anguliscuta sp. n. from lizards and bats, and E. leiocephali sp. n. from lizards, are described. One species, E. lipovskyana (Wolfenbarger, 1953), is recorded for the first time in Cuba. Data on distribution of E. alfreddugesi (Oudemans, 1910) in Cuba are reported.

Two new species of the goblin spider genus Antoonops are described, bringing the total number of species to six. Antoonops kamieli sp. nov. is described from two males and one female collected in Bouaké, Ivory Coast. The species can be easily distinguished from congeners by its large eyes. In addition, the males are characterized by a distinct depression on the ventral abdomen. Antoonops sarae ...
