  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.

The postembryonic development of Centruroides ochraceus (Pocock, 1898) from Yucatan, Mexico (Scorpiones: Buthidae), with comments on parthenogenesis

Abstract 

Since general data on the biology of scorpions remain rare, we propose in this note some results on the postembryonic development of the buthid scorpion Centruroides ochraceus (Pocock, 1898), species distributed in the Yucatan peninsula, Mexico. The results were originally observed almost 40 years ago, based on some specimens collected by the senior author. A possible case of parthenogenesis is also suggested for this species.
