- Observation All examined taxa had 2 n = 24 chromosomes.
- Observation Chromosome numbers were first reported for S. tripartitum, S. tenuispinum and S. vaillantii.
- Observation The first genus-level karyotype analysis of L. rantonnei is reported.
- Observation Karyotypes were generally symmetrical, with chromosomes under 4 μm.
