A new species of moth-fly, Tonnoira igrapiunensis sp. nov. (Psychodidae, Psychodinae), from the Brazilian Atlantic Rain Forest is described. The new species can be distinguished from other species of the genus by its eye bridge separated by 0.5 facet diameter, R₅ ending slightly posterior to apex of the wing, gonostyli bifurcated with long arm shorter than length of gonocoxites, aedeagus bipartite and asymmetrical, and two asymmetrical parameres. The gonostylus is similar to that of Tonnoira andradei Santos, 2014, but in the latter species the aedeagus has only one shaft and not two as in the new species. Tonnoira bifida Bravo & Chagas, 2004, Tonnoira brisolaii Santos, 2014, and Tonnoira galatiae Santos, 2014 have their distribution expanded.

This contribution is an update catalogue of the type specimens of Insecta deposited in the entomological collection Prof. Johann Becker of the Museum of Zoology of Universidade Estadual de Feira de Santana, Bahia, Brazil. A list of 206 holtypes and 1,430 paratypes of 23 families, 73 genera, and 244 species allocated in 12 orders. Lectotype and paralectotypes of Bitoma palmarum Bondar, 1940 were designated. Diptera present the highest number of types on the collection, with 161 holotypes and 1,324 paratypes.

Arisemus atlanticus Vilarinho, Araújo, Bravo & dos Santos sp. nov. and Arisemus benignoi Vilarinho, Araújo & Bravo sp. nov. are described from the Central Corridor of the Atlantic Forest. Currently, thirty-three species of the genus has been described from the Neotropical Region and only one from Brazil.
