Abstract
Dolabellopsocus Eertmoed, 1973, is the most species-rich genus within the Dolabellopsocidae, comprising 24 species distributed across Central and South America. Recent collections from Central Amazonia, near Manaus, yielded male and female specimens belonging to the Dolabellopsocidae, including Dolabellopsocus similis Mockford, 1991, previously recorded only in Roraima, Brazil, and Colombia. This study presents a new record of D. similis in Amazonas State and it provides an updated diagnosis and redescription of the species, highlighting morphological variations, particularly in wing structure and the clunial comb. A new species, Dolabellopsocus rebecandradeae sp. nov. is described in honor of the gymnast Olympic brazilian athlete Rebeca Rodrigues de Andrade. The findings emphasize the ongoing challenges in addressing Linnaean and Wallacean shortfalls in the study of free-living lice, especially in Brazil, where vast biodiversity and a lack of specialized taxonomists contribute to gaps in species knowledge. Detailed morphological analysis, including illustrations of male genital structures, nymphal stages, and a distribution map, further enhances understanding of these species.
