Abstract

<br> Katiannoidea Bretfeld is a widespread superfamily of Symphypleona that holds taxa with a trochanteral organ on leg III. Collophoridae is a monogeneric family of Katiannoidea composed solely of<br> Collophora<br> Richards, and its species are characterized by having 4+4 eyes and a modified capitate bothriotrichum D. The genus has a mostly Holotropical distribution, with species found in the Americas, Africa, and Asia. The overall morphology of<br> Collophora<br> remains poorly understood, as most species descriptions are insufficient by current Symphypleona taxonomic standards. In this study, we describe a new species of<br> Collophora<br> from northeastern Brazil, characterized especially by its purple body, the presence of ciliated chaetae on the fourth antennal segment, a manubrium with 4+4 chaetae, and a dens with eight dorsal chaetae, four of which are modified into spines. We also provide a bibliographic survey with the diagnoses of all<br> Collophora<br> species, an identification key, and a brief discussion on the validity of the families within Katiannoidea, which have never been properly tested using modern phylogenetic methods.<br>
