1. Soil temperatures affect the anatomical and morphological character of root systems. 2. Four larval instars have been described based on their morphological characters . 3. These ridges are also important morphological characters useful for identifying species. 4. Clarke lists the following morphological characters that distinguish the two species. 5. Recent phylogenetic analyses using combined molecular and morphological characters supports the previous phylogeny. 6. Morphological characters can be found to support either hypothesis.7. It also differs in lateral photophore count, as well as in morphological characters . 8. Unfortunately, the material so far described from Sirius Passet is sparse in morphological characters . 9. There are however no known morphological characters that would clearly distinguish it from the others. 10. Other authors still divide the genus into subgenera using morphological characters to make identification easier.
