Two new species of Salina MacGillivray (Collembola, Paronellidae) with rectangular mucro from South America

Authorship SCIMAGO INSTITUTIONS RANKINGS

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.
