Golofa tersander is a sexually dimorphic species with males possessing a long, slender horn arising from the frons, a distinct pronotal tubercle anteriorly, a strongly convex pygidium, and an apically emarginate last sternite. Females, on the other hand, have only a tubercle on the frons, lack a pronotal tubercle, possess a relatively flat pygidium, and the last sternite is entire apically. Both of the specimens described here exhibit all of these external male character states just mentioned.
