Palpal teratology is newly reported and illustrated in males of three species of spiders: Hibana incursa (Chamberlin, 1919) (Anyphaenidae) from Mexico, Chococtenus lasdamas Dupérré, 2015 (Ctenidae) from Ecuador (also being newly recorded from the province of Pichincha and the highest altitude record for the species), and Xerolycosa nemoralis (Westring, 1861) (Lycosidae) from Russia. The first detailed photographs and descriptions of the anomalous palps of males of Epicratinus maozinha Gonçalves et Brescovit, 2024 (Zodariidae) from Brazil and Carrhotus assam Caleb, 2020 (Salticidae) from India are presented. Finally, a synopsis of the other literature on palpal teratology in adult male spiders is given.
