What is the primary basis upon which researchers might distinguish between wolf snake species in a region like Sulawesi, given overlapping presence?

Answer

Subtle morphological differences and island geological history

When species like *L. aulicus* and *L. capucinus* both inhabit an island such as Sulawesi, differentiation requires looking beyond simple geography. Identification relies on observing subtle morphological differences between the snakes themselves. Furthermore, researchers consider the island's historical geological connection to the Asian mainland, as dispersal histories influence which species became dominant or established on specific islands within archipelagos like the Sunda and Sahul regions.
