Two new jumping spider species of the Habronattus clypeatus group (Araneae, Salticidae, Harmochirina)

Abstract. Two species of the Habronattus clypeatus species group are described, Habronattus arcalorus sp. n. from Texas and Colorado, and Habronattus gilaensis sp. n. from New Mexico. Habronattus arcalorus males have extravagant ornamentation: a green first leg with an unusually dense lateral fringe of orange and white hairs, and a large grey triangular patella on the third leg with blue-white scales nearby. Habronattus gilaensis males are considerably more muted, lacking ornamentation on the third leg’s patella and tibia. Photographs of living specimens are given, as well as notes on habitat.
