Diversity of stink bugs (Hemiptera: Heteroptera: Pentatomoidea) in the Brazilian Pampa and the Parque Estadual de Itapuã, Rio Grande do Sul.

Biological surveys represent important contributions to the knowledge of species diversity, conservation, taxonomy, and biogeography. Few surveys of stink bugs and allied groups (Pentatomoidea) were produced in Brazil, especially regarding the Brazilian Pampa, an overlooked biome. Here, a list of Pentatomoidea species of the Brazilian Pampa is presented for the first time, composed of seven families and 152 species.

Description of the immature of Podisus graziae Brugnera, Roell & Lemaître, 2021 (Heteroptera: Pentatomidae: Asopinae).

As predaceous insects, the Asopinae have a great economic importance. The knowledge about the development of the species is essential for use in biological control programs. However, only 1% of the Neotropical Asopinae species have the immature stages known.

Taxonomic modifications in Tylospilus Stål (Hemiptera: Pentatomidae: Asopinae): redescription of T. nigrobinotatus (Berg), description of a new species and an updated identification key for the genus.

The systematics of the New World Asopinae genera is still not completely understood, thus hampering their study in many areas of biological science. Tylospilus Stål is one of the less known genera among New World predatory stink bugs, despite its common occurrence and potential as a biological control agent in crops. Here, we make a contribution to the knowledge of Tylospilus; the species Tylospilus nigrobinotatus (Berg, 1879) is redescribed, and based upon the examination of type specimens, T.
