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

Abstract We propose the name Bumba as a new name for Maraca, preoccupied by Maraca Hebard, 1926 (Orthoptera). We describe and illustrate Bumba lennoni, 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.


Introduction
The genus Maraca Pérez-Miles, 2005 was originally described as a replacement name for Iracema Pérez-Miles, 2000 which was preoccupied by Iracema Triques, 1996in Pisces. Pérez-Miles (2005 was again unaware that the name Maraca was previously used for a Neotropical cockroach (Hebard 1926). To remove this generic homonymy the name Bumba is here proposed for Maraca Pérez-Miles (2005). The type species Bumba cabocla (Pérez-Miles 2000), comb. n. is so far recorded solely for the type locality, Maracá Island, State of Roraima northern Brazilian Amazonia. Bumba horrida (Schmidt 1994), comb. n. was transferred from the genus Paraphysa Simon, 1892 by Bertani and Carla-da-Silva (2003) to Iracema and, by the homonymy, fall into Maraca and now into Bumba. These authors extended the records of Bumba horrida from its type locality in Amazonas Federal Territory, Venezuela to the states of Amazonas and Roraima, Brazil. Recently, Perafán and Pérez-Miles (2014) transferred Euathlus pulcherrimaklaasi (Schmidt, 1991) to Maraca including Ecuador in the distribution of the genus.
Bumba (formerly Maraca) is characterized by the presence of type IV urticating hairs, a retrolateral process on male palpal tibiae, palpal bulb resting in a ventral distal excavation of palpal tibia, male metatatarsus I passing between tibial spurs when flexed, and spiniform setae on prolateral and retrolateral maxillae and coxae I-IV (Pérez-Miles 2000, Bertani and Carla-da-Silva 2003). Besides these characters, the reduced number of cuspules on labium was also indicated as diagnostic for Bumba; the new species fits in all other generic characters but has about 50 cuspules on labium. Consequently, the diagnosis of Bumba is presently modified in this point. We here diagnose, describe and illustrate B. lennoni sp. n., based on male and female specimens from Caxiuanã, Pará, Brazil. Some brief additional natural history comments on B. lennoni sp. n. are given. Three new combinations are established: Bumba cabocla (Pérez-Miles, 2000), Bumba horrida (Schmidt 1994) and Bumba pulcherrimaklaasi (Schmidt, 1991).

Diagnosis.
Bumba differs from other genera of Theraphosinae in the combined presence of type IV urticating hairs, retrolateral process in male palpal tibiae, palpal bulb resting in a ventral distal excavation of palpal tibia, male metatatarsus I passing between tibial spurs when flexed, and spiniform setae on prolateral and retrolateral maxillae and coxae I-IV.
Type species. Bumba cabocla (Pérez-Miles, 2000), comb. n. Etymology. Bumba (feminine) is taken from Brazilian theatrical folk tradition of the popular festival called Boi-bumbá (hit my bull), which takes place annually in North and Northeastern Brazil.

Bumba lennoni
Natural history. All specimens from Estação Científica Ferreira Penna, FLONA Caxiuanã were collected in pit-fall traps used for herpetological surveys or in nocturnal manual searching, in both flooded and dry areas.
