Acutipetala, gen. nov., a New Genus of Funnel-Web Spiders from Northern Thailand (Araneae, Agelenidae)

Abstract A new funnel-web spider genus, Acutipetala, gen. nov., is erected to accommodate two new agelenid species known to occur in evergreen forests of northern Thailand: Acutipetala octoginta, sp. nov. (type species,♂♀) and A. donglini, sp. nov. (♂). The genus is established on the basis of the distinctive appearance of the genital structures, in which the median apophysis of the male palp is petal-shaped, sharply pointed, and strongly sclerotized, and the truncate embolus is short, originates subapically, and is provided with a hook-shaped apical portion.
