  New locality records and future habitat suitability of Sassanidotus gracilis (Birula, 1900) (Scorpiones: Buthidae) in the Iran–Afghanistan–Pakistan arid belt Abstract This study reports new locality records from Iran and a climate-based habitat suitability assessment for Sassanidotus gracilis (Birula, 1900) (Scorpiones: Buthidae) in the Iran–Afghanistan–Pakistan arid belt. We document new specimens from Sistan and Baluchestan Province, Iran, with an updated distribution map and illustrations, and we model the species' potential distribution across south-eastern Iran and adjacent parts of Afghanistan and Pakistan. Habitat suitability was associated mainly with precipitation seasonality, precipitation of the wettest month, precipitation of the driest month, and slope. In an arid setting these rainfall variables are unlikely to indicate a need for moist habitat; they more plausibly track seasonal productivity and the terrain features that provide shelter. Present-day suitable areas...

First catalog of Salticidae (Arachnidae, Araneae) from French Guiana, with the description of one new species

A work of bibliographic synthesis and identification of collected material made possible to complete the knowledge concerning one of the best studied spider families of the neotropical region from a systematic point of view, namely the Salticidae Blackwall, 1841. This catalog lists the presence of 122 species as well as 68 morphospecies, belonging to 36 genera, making a total of 190 potential species. After argument based on the observation of type species or individuals, exchanges with data producers or even verification of data in the bibliography, the following species, 19 in number, are deleted from the list of Salticidae of French Guyana: Amycus ectipus (Simon, 1900), Amycus pertyi Simon, 1900, Anasaitis canosa (Walckenaer, 1837), Chira simoni (Galiano, 1961), Chirothecia crassipes (Taczanowski, 1878), Colonus germaini (Simon, 1900), Corythalia tropica (Mello-Leitão, 1939), Hypaeus miles Simon, 1900, Lyssomanes amazonicus G. W. Peckham, E. G. Peckham & Wheeler, 1889, Lyssomanes elegans (Cambridge, 1900), Lyssomanes parallelus (Peckham & Wheeler, 1889), Matinta fasciata (Mello-Leitão, 1940), Noegus bidens (Simon, 1900), Noegus petrusewiczi Caporiacco, 1947, Psecas bubo (Taczanowski, 1871), Sarinda atrata (Taczanowski, 1871), Scopocira melanops (Taczanowski, 1871), Rudra wagae (Taczanowski, 1871) and Viciria chabanaudi Fage, 1923. The mention of a species in Vedel et al. (2013), not recognized by the World Spider Catalog (2023), is also deleted: Salticus fulvatus (Fabricius, 1896). The following new synonymy is established: Amycus flavolineatus C. L. Koch, 1846 is a junior synonym of Colonus sylvanus (Hentz, 1846), n. syn. Amycus amrishi Makhan, 2006 and Neonella heliophanina (Taczanowski, 1871) are considered as nomina dubia. Pseudopartona ornata Caporiacco, 1954, type species of the genus Pseudopartona Caporiacco, 1954 , belongs to the genus Sassacus Sassacus G. W. Peckham & E. G. Peckham, 1895, which results in Pseudopartona being synonymised with Sassacus, and the following new combination Sassacus ornatus (Caporiacco, 1954) n. comb. Finally, 25 species are newly cited, including one newly described species: Eustiromastix agatheae Courtial & Picard n. sp. (male).
