Acutipetala, gen. nov., a new genus of funnel-web spiders from northern Thailand (Araneae, Agelenidae).

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,male symbolfemale symbol) and A. donglini, sp. nov. (male symbol). 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.
