HUMBOLDT-PAPUTSACHIS, Ciro; VILLARREAL-CARVAJAL, Jeysa Camila  and  FORTUN FERNANDEZ, Evelin Esther. Taxonomic redescription of Tityus (Tityus) proseni Abalos 1954 (Scorpiones: Buthidae) and first record for the departments of Beni and Santa Cruz - Bolivia. J. Selva Andina Res. Soc. [online]. 2025, vol.16, n.2, pp.81-91.  Epub Aug 31, 2025. ISSN 2072-9294.  https://doi.org/10.36610/j.jsars.20252326.

In 1954 Abalos described the species Tityus proseni with specimens found in Cochabamba-Bolivia, however, since then the data of the species have not been updated. New specimens were recently captured from the departments of Beni and Santa Cruz - Bolivia. In order to carry out a detailed redescription and expansion of the distribution data of the species in Bolivia, these were reviewed according to: its external morphology, pigmentation patterns and morphometric data. The data resulting from the analysis provide new characters for the species, not contemplated in the original description, new ranges in morphometric variables previously analyzed, new data on pigmentation patterns. On the other hand, the differential morphological and morphometric data of T. proseni with those of T. argentinus and T. sorataensis are presented, since they are apparently similar species within the country.

Keywords : Bolivia; Tityus proseni; morphometrics; morphology; distribution.
