Bumba, a replacement name for Maraca Pérez-Miles, 2005 and Bumbalennoni, a new tarantula species from western Amazonia (Araneae, Theraphosidae, Theraphosinae)

We propose the name Bumba as a new name for Maraca, preoccupied by Maraca Hebard, 1926 (Orthoptera). We describe and illustrate Bumbalennoni, a new theraphosid species from Caxiuanã, Pará, Brazil. This species differs from the other species of the genus in the extremely reduced keel on male palpal organ and in the higher number of labial and maxillary cuspules. Females additionally differ in the spermathecal morphology. As a consequence of the name replacement, three new combinations are established.
