ABSTRACT Two new species of Salina, S. maculiflora sp. nov. from Brazil and S. colombiana sp. nov. from Colombia are described and illustrated. The complete dorsal chaetotaxy, including the specialized chaetae (S-chaeta), is studied in these new species. Comparisons based on the chaetotaxy of the basomedian field, abdomen II, and mucro shape are made between species from groups beta, celebensis, and borneensis. This is the first record of Salina with rectangular mucro (beta group) in South America and a key to the seven Nearctic and Neotropical species is provided.

Seira caerucinerea sp. nov. , a new species of springtail from the Cerrado domain, state of Tocantins, Brazil, is described and illustrated. The new species is mainly characterized by bluish-gray coloration and dorsal chaetotaxy presenting macrochaeta S7 on head, three macrochaetae (a6, m6 and p6) on margin of metathorax and 4+4 macrochaetae (a1, m2, m3 and m4i) on abdomen I. Characteristics of maxillary and labial papillae, chaetotaxy of subcoxae, collophore, ventral region of head, ventral and lateral region of abdomen IV and V, which are usually omitted in species descriptions within the genus, are also provided. This is the first species of Seira described from the Cerrado domain, as well as the first record of the genus from the state of Tocantins.
