What is "acutipetala"

Acutipetala is a genus of funnel web spiders native to evergreen forests of northern Thailand that includes two species, A. donglini and A. octoginta. They are medium sized spiders, and can be distinguished by the distinctive appearance of several genital structures, including the embolus and the median apophysis of the male pedipalp. Spiders of this genus are to long. The eyes are in two rows, both of which are strongly curved forward. The name is a combination of the Latin "acutus", which means "sharp", and the Greek "petalon", which means "leaf" in reference to the sharp, petal shape of the medial apophysis of the male pedipalp.
