Before detailing our new taxonomy, we consider the background on the state of Placozoa taxonomy. Currently, there are three described genera. Polyplacotoma is monotypic and has so far not been assigned to a higher taxonomic rank such as a family (Osigus et al., 2019). Placozoa is an ancient phylum of extraordinarily unusual animals: miniscule, ameboid creatures that lack most fundamental animal features. Despite high genetic diversity, only recently have the. • A register designed to record all published usages of scientific names for animals which represent nomenclatural acts as governed by the International Code of Zoological Nomenclature. Spermophor running from disto-retrolateral part of tegulum proximally, then into a proximo-prolateral loop before entering the embolus (Figs 1–3, 17–18). Placozoa is an ancient phylum of extraordinarily unusual animals: miniscule, ameboid creatures that lack most fundamental animal features. Despite high genetic diversity, only recently have the second and third species been named. While prior genomic studies sufer from incomplete placozoan taxon sampling, we more than double the count with protein sequences from seven key genomes and produce. Abstract Defining species limits and describing species of ants are important to identify taxa and habitats with elevated diversity in areas of high conservation priority such as the Malagasy region. The Pachycondyla wasmannii-group is revised in the Malagasy region where eight species are recognized, four of which are new: P. masoala sp. n., P. planicornis sp. n., An endemic new species of Andean lizard of the genus Liolaemus from southern Peru (Iguania: Liolaemidae) and its phylogenetic position 1,2,*Juan C.
