is the most speciose genus of the family Pimelodidae, and is amply distributed in the Neotropical region. The species-level taxonomy and phylogenetic relationships within this genus are still poorly resolved, however. These taxonomic problems and the general lack of data have generated major uncertainties with regard to the identification of specimens from different localities.

- A study analyzed Bacillus thuringiensis (Bt) isolates from Maranhão (BtMA) that are toxic to Aedes aegypti larvae, using rep-PCR techniques with various genetic markers to assess genetic diversity.
- The rep-PCR analysis identified 38 genetic variations and revealed eight distinct groups, indicating significant genetic diversity among 30 BtMA isolates.
- Despite the genetic diversity, the study found a low correlation between the collection site and the effectiveness in killing A. aegypti larvae, suggesting that BtMA isolates could be effective alternatives for controlling this mosquito and other harmful pests.
