  Scorpiops walteri sp. n. (Scorpiones: Scorpiopidae) from Myanmar Abstract A new species Scorpiops walteri sp . n . (Scorpiopidae) is described from Myanmar, fully illustrated with color photos showing its morphology and habitus. Scorpiops walteri sp . n . is the only species of the genus with a combination of the following five characters: chelal trichobothrium Eb 3 located in middle of manus between trichobothria Dt and Est ; patella of pedipalp with 11–12 ventral and 19 external trichobothria; fingers of pedipalps strongly undulate in male; pedipalp movable finger with ca. 47 IAD; and chela length to width ratio 2.8 in male.

Description of a new Andean species of widow spider (Araneae, Theridiidae, Latrodectus)

Abstract

We describe a new species of widow spider (Araneae, Theridiidae, Latrodectus) from the Andean region. DNA barcode sequences are provided. The species is documented from museum specimens across Peru and identified from photographs on iNaturalist, extending its inferred distribution into Ecuador, Bolivia, and Chile. We integrate specimen and citizen-science occurrences to generate a species distribution model using WorldClim bioclimatic variables, predicting highest suitability along temperate to high-elevation Andean regions. We discuss the utility and limitations of citizen-science imagery for delimiting and mapping species and summarize available information on clinical aspects of envenomation in Peru associated with the local “lucacha” widow spider.
