differentiation of threatened marine invertebrates, is published in the journal Invertebrate Systematics . At present, the diversity of some groups of small starfish is not known with certainty. The morphological analysis of these marine animals does not always allow a clear differentiation and, therefore, researchers have used genetic analysis Ghana WhatsApp Number List techniques to study the different varieties of stars of the genus Asterina. Analysis using various molecular markers allowed the identification of five different species, which were later confirmed by a detailed morphological study. Among them, the scientists detected two species new to science. “As in any group of organisms, for small starfish of the genus Asterina, knowledge of their diversity is essential for their conservation”,

explains the MNCN researcher Violeta López. Taxonomy of ‘Asterina’ In addition to the discovery of the two new species, the work has confirmed the assignment to the genus Asterina of the three previously known star species, morphologically characterized with traditional methods. Through genetic analysis of various samples, scientists have shown that they are Asterina gibbosa, Asterina pancerii and Asterina phylactica. In the case of the last two, they have analyzed the material that served as the basis for their original descriptions, managing to sequence DNA from samples preserved or dried between the 50s and 70s of the last century, from the Museo Civico di Storia Naturale Giacomo Doria (Italy) and the Natural History Museum (UK)

. “All this information has made it possible to clarify the taxonomy of this group of small starfish and to differentiate the different species within the genus Asterina”, points out Iván Acevedo, also a scientist at the MNCN. Knowledge of the species that make up this genus of starfish, some of which are seriously threatened, is essential to guarantee their conservation, as the researchers point out. Violeta López-Márquez, Iván Acevedo, M. Eugenia Manjón-Cabeza, Ricardo García-Jiménez, José Templado and Annie Machordom. Looking for morphological evidence of cryptic species in Asterina Nardo , 1834 (Echinodermata: Asteroidea). The redescription of Asterina pancerii (Gasco, 1870) and the description of two new speciesyear-old Neolithic farmer has been sequenced, making it the oldest sequenced human genome in southern Spain. the Iberian
