We have two of them: A review of the genus Mastigusa (Araneae: Cybaeidae) in Bulgaria

In the present study, we review the status of the genus Mastigusa Menge, 1854 in Bulgaria. We identified two species from the country, namely Mastigusa arietina (thorell, 1871) and M. macrophthalma (kulczyński, 1897). this is the first record of Mastigusa arietina from Bulgaria. Furthermore, we report a male palpal polymorphism in Mastigusa arietina in the populations around the Black Sea. We also provide molecular support for our conclusions, combining newly generated DNA sequences with information available in genBank.
