Two parasitoid wasps of the genus Zatypota are described and illustrated, both koinobiont ectoparasitoids of the spider Anelosimus baeza (Theridiidae) and both show the same development time, which was longer when compared with other parasitoids wasps. Expand
Trunk structural traits explain habitat use of a tree-dwelling spider (Selenopidae) in a tropical forest
The results indicate that the selection of host plants by S. cocheleti is not species-specific, but based on the structural characteristics of plants, which may benefit spiders by providing shelter against predators and harsh climatic conditions. Expand
The wasp Flacopimpla varelae Gauld (Ichneumonidae: Pimplinae), parasitoid of the spider Achaearanea tingo Levi (Theridiidae: Theridiinae), with description of the male wasp.

Wasps of the Polysphincta genus-group sensu Gauld Dubois, 2006 are well known to act exclusively as koinobiont ectoparasitoids of spiders, but the host range of these wasps is remarkably narrow and often species-specific. Expand
First record of Epipompilus excelsus (Bradley, 1944) (Hymenoptera, Pompilidae) as a koinobiont ectoparasitoid of Ariadna mollis (Holmberg, 1876) (Araneae, Segestriidae)
It is demonstrated that the Neotropical species of Epipompilus exhibit biological characteristics similar to the Australian species, acting as a koinobiont ectoparasitoid, but displays differences in larval morphology. Expand
First record of egg sac predation on a wall crab spider Selenopidae (Araneae) by the wasp Camera lunavenatrix sp. n. (Ichneumonidae, Cryptinae)
The first record of egg sac predation on the wall crab spider Selenops cocheleti by wasps of the genus Camera with the description of a new species, as well as biological information on the wasp and the spider host. Expand
Conura baturitei sp. nov. (Hymenoptera: Chalcididae): a hyperparasitoid of spiders through Zatypota riverai (Hymenoptera: Ichneumonidae).
Conura, the largest genus of Chalcididae (Hymenoptera: Chalcidoidea), is mostly distributed in the New World where 295 of the 301 described species occur. Chalcididae are in some cases… Expand
Population dynamics and phenology of two congeneric and sympatric lynx spiders Peucetia rubrolineata Keyserling, 1877 and Peucetia flava Keyserling, 1877 (Oxyopidae)
The population dynamics and phenology of two congeneric lynx spider species were examined in southeastern Brazil and the variation in the total abundance of individuals and age structure and their relationship with climatic variables were similar between the two spiders. Expand
Population dynamics and phenology of the wall crab spider Selenops cocheleti Simon, 1880 (Araneae: Selenopidae) in Southeastern Brazil
New insights are provided into the life-history of S. cocheleti and how climatic variables and prey abundance influence the population abundance of the different age classes and adult sexes. Expand

Information is presented about a new interaction between the parasitoid spider wasp Zatypota riverai Gauld, 1991 and the host spider Theridion sp. Expand

The spider genus Macrophyes O. attenuata, the type species, by Pickard-Cambridge (1893) includes five species from the Neotropical region, known until now only by the male, and know by both sexes. Expand
