Vertical and time distribution of
Pseudoscorpiones (Arthropoda: Arachnida) in a floodplain forest in the Brazilian Pantanal.
The groups of captured individuals were classified in the following taxonomic levels: Diplopoda (class); Acari (Subclass); Araneae, Blattodea, Coleoptera, Collembola, Diptera, Hemiptera, Hymenoptera, Isoptera, Orthoptera,
Pseudoscorpiones, Scorpiones, Solifugae (order); Formicidae (family) and the larvae of Coleoptera, Diptera and Lepidoptera (morphospecies).
mexicana, son escasos, sin embargo, en un trabajo reportan artropodos clasificados en tres clases y 13 ordenes: 1): clase Arachnida: Araneae,
Pseudoscorpiones y Acari, de este ultimo orden estuvieron representados cinco grupos principales de acaros (Ixodida, Mesostigmata, Prostigmata, Astigmatina y Oribatida); 2) clase Insecta: Psocoptera, Collembola, Dyctyoptera, Hemiptera, Thysanopetra, Coleoptera, Lepidoptera, Diptera, Siphonaptera e Hymenoptera; y 3) clase Diplopoda (Villegas-Guzman et al., 1998).
In Coleoptera, Lepidoptera, Diptera (Insecta) and
Pseudoscorpiones (Arachnida), Wolbachia induce male killing of infected females' male progeny.
Order
Pseudoscorpiones represents 3.3% of all known arachnid species (Harvey, 2002; Harvey, 2007).
Crustacea dominate as predators (Cheng 1976), while a range of centipedes (Class Chilopoda), symphylids (Class Symphyla), pauropods (Class Pauropoda), millipedes (Class Diplopoda), scorpions (Order Scorpiones), microwhip scorpions (Order Palpigradi), pseudoscorpions (Order
Pseudoscorpiones), mites and ticks (Order Acari) and spiders (Order Araneae) have also been recorded as living in the intertidal region worldwide (Roth & Brown 1976).
Other prey items, such as lepidopterans, hymenopterans,
pseudoscorpiones, and chilopods, were found in much lower percentages (Table 3).

Visual surveys captured an additional 11 species and were responsible for the capture of all arachnids from class Araneae and
Pseudoscorpiones. Entomobryidae was the most prevalent family captured in the baited ramp-pitfall traps comprising 46% of the total captures followed by Phoridae which accounted for another 30% of the specimens.
