In a cladogram, the more related species join by just one node, for example, Chironax melanocephalus and Otopterus cartilagonodus are very closely related in this cladogram.

The more nodes between two species, the least related they are.

We have the following options:

• Ptenochirus minor, and ,Megaerops niphanae, have ,2 nodes ,between them.

,

• Dyacopterus spadiceus, and ,Otopterus cartilagonodus ,have ,3 nodes, between them.

,

• Haplonycteris fischeri , and ,Ptenochitus jagori , have ,6 nodes, between them

• Cynopterus sphinx, and ,Chironax melanocephalus ,have ,3 nodes, between them

This means the least related pair is Haplonycteris fischeri and Ptenochitus jagori because they have 6 nodes in the middle of them.
