Abstract

Adults of Bandakia hoffmannae sp.nov., Bandakia mexicana sp.nov., Chappuisides notialis sp.nov., and Neoacarus adocetus sp.nov., all collected in the mountains west of Mexico City, are described. These are the first reports of species of these three essentially holarctic genera from south of the United States border in North America. These discoveries provide new insight concerning the extent of refugial areas for freshwater arthropods in southern North America during the Pleistocene.

Résumé

On trouvera ici la description des adultes de Bandakia hoffmannae sp.nov., Bandakia mexicana sp.nov., Chappuisides notialis sp.nov. et Neoacarus adocetus sp.nov., provenant des montagnes situées à l’ouest de Mexico. C’est la première fois que des espèces de ces trois genres essentiellement holarctiques sont trouvées au sud de la frontière américaine. Ces découvertes permettent d’envisager de nouvelles hypothèses au sujet de l’étendue des refuges qui s’offraient aux arthropodes dulcicoles dans la partie méridionale de l’Amérique du Nord au cours du Pléistocène.
