Post-traumatic phenomena secondary to snakebite envenomation: a psychiatric clinical perspective

  Post-traumatic phenomena secondary to snakebite envenomation: a psychiatric clinical perspective Abstract Snakebite envenomation represents a major global public health concern. Beyond physical outcomes suffered by the patients, studies have documented significant psychiatric and psychological sequelae. Consequently, there is an urgent need to document and intervene the psychiatric/psychological sequelae of snakebite envenomation alongside the clinical assessment. This work presents a narrative review of the psychiatric consequences described in snakebites in several settings. In addition, it addresses the screening/detection actions focused on Post-Traumatic Phenomena from a psychiatric perspective that are useful in general and specialized medicine settings in snakebite envenomation.

Description of a new species of Chaco Tullgren, 1905 (Araneae: Mygalomorphae: Pycnothelidae) from Argentina and the southernmost record of the genus

Abstract

A new species of Chaco Tullgren, 1905 was discovered and is formally described. Chaco aoni sp. nov. from the Santa Cruz River in Santa Cruz Province, Argentina, is the southernmost recorded species of this genus. The new species is diagnosed on the basis of the morphology of the palpal organ and tibial apophysis of males and the shape of the spermathecae of females. A cladistic analysis was carried out based on an already published morphological matrix, which now also includes the new species. This new species is part of a monophyletic group including also Chaco tingua Indicatti, Folly-Ramos, Vargas, Lucas & Brescovit, 2015, C. tecka Goloboff, 1995, C. sanjuanina Goloboff, 1995, C. patagonica Goloboff, 1995 and C. ansilta Ferretti, 2014.
