  A new species of the genus Spinoctenus Hazzi, Polotow, Brescovit, González-Obando et Simó, 2018 (Araneae: Ctenidae) from Panama A new species Spinoctenus leleji sp. n . is described from Panama based on a male specimen. This is the first record of the genus Spinoctenus from Panama and the second record of this genus outside South America. The new species is most similar to S. tequendama Hazzi, Polotow, Brecovit, González-Obando et Simó, 2018, but differs by the structure of the male palp and the shape of metatarsus IV. Photographs of the habitus and copulatory organs are provided. The type locality of the new species is mapped. Omelko, Мichail M. 2026.

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

Abstract

In the present study, we review the status of the genus Mastigusa Menge, 1854 in Bulgaria. We identified two species from the country, namely M. arietina (Thorell, 1871) and M. macrophthalma (Kulczyński, 1897). This is the first record of M. arietina from Bulgaria. Furthermore, we report a male palpal polymorphism in M. 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.
