| Record 1 |
| Geographical area of study |
Aguapeu - Mongagua-Sap Paulo River, Brazil |
| Source of chromosomes |
Not reported |
| Number of specimens with sex |
05 |
| Diploid chromosome number |
52 |
| Karyotype formula |
32m+18sm+2st |
| Fundamental arm number |
Not reported |
| Chromosome length |
Not reported |
| Sex chromosome |
Not reported |
| Chromosome staining/banding/FISH |
The C-banding technique revealed centromeric marks in all chromosomes. NORs were localised on first chromosome pair, as revealed by silver staining and hybridization with 18S rDNA probes. The 5S rDNA probes revealed signals on two pairs |
