The status of Heteromurini Absolon & Ksenemann is analyzed and a new diagnosis is proposed to the tribe. New chaetotaxic characteres were added to distinguish Dicranocentrus Schött and Pseudodicranocentrus Mari Mutt. Alloscopus Börner, Heteromurtrella Mari Mutt and Verhoeffiella Absolon, originally proposed as subgenera of Heteromurus Wankel, are reviewed and a new diagnosis and generic status are proposed. The presence of the postantennal organ becomes the main characteristic to distinguish Alloscopus (present) and Heteromurtrella (absent). Alloscopus yosiius Mari Mutt, anteriorly synonymized with Alloscopus tenuicornis Börner, is revalidated. The absence of S0 macrochaeta on head of Heteromurus is reported now as a characteristic also shared with Heteromurtrella. Heteromurtrella zairensis Tshelnokov comb. nov. is transferred from Heteromurus by the presence of macrochaetae on abdomen I. Heteromurtrella anae sp. nov. from Brazilian Amazon is described and illustrated, including detailed dorsal chaetotaxy. This is the first record of Heteromurtrella in Brazil. Heteromurus now has 17, Alloscopus 10 and Heteromurtrella 20 valid species worldwide. An identification key and diagnosis for the six genera of Heteromurini and species of Alloscopus and Heteromurtrella are provided.

The survey of Seira Lubbock, 1870 (Collembola, Entomobryidae, Seirinae) from Iberian Peninsula and Canary Islands, including three new species

Troglobius albertonoi sp. nov. (Collembola: Paronellidae: Cyphoderinae) from the Brazilian Amazon is described and illustrated. The shape of the mucro and unguis resemble those of T. ferroicus Zeppelini, Silva & Palacios-Vargas, recently described from Brazil, but the chaetotaxy is distinct. This is the 4th species of the genus and the 3rd from Brazil. Variation within the genus Troglobius of the dorsal chaetotaxy and the geographic distribution are discussed, and an identification key to the species is provided. Troglobius albertonoi sp. nov. is the only known epigeous species of the genus. Resumo Troglobius albertonoi sp. nov. (Collembola: Paronellidae: Cyphoderinae) da Amazônia Brasileira é descrita e ilustrada. A forma do mucro e unguis da nova espécie assemelham-se com T. ferroicus Zeppelini, Silva & Palacios-Vargas, recentemente descrita do Brasil, embora o padrão quetotáxico das espécies sejam claramente distintos. Esta é a quarta espécie descrita do gênero e a terceira proveniente do Brasil. Informações comparativas sobre a quetotaxia dorsal e distribuição do gênero são discutidas e uma chave de identificação para as espécies é fornecida. Troglobius albertonoi sp. nov. corresponde à primeira espécie epigeica do gênero reportada na literatura.
