Trachyaretaon negrosanon is a stick insect species from the family Heteropterygidae native to Negros.

[1] In habit the species corresponds to typical representatives of the Obrimini, but shows very characteristic features in both sexes.

The secondary ovipositor is formed dorsally from the supraanal plate (epiproct), which is laterally straight and about 1.8 times longer than the anal segment.

An often yellow-brown, rarely greenish longitudinal line runs over the meso- and metanotum and, more indistinctly, over the first six abdominal segments.

The upper quarter and operculum are dark gray to black and densely covered with short bristles.

The specific name is dedicated to the cultural group of the Negrosano, which stands for Negrenses in Cebuano language.

A female collected by Arimas from Mount Kanlaon is deposited as holotype in the Museum of Natural Sciences in Brussels.

Eggs from specimens collected by Arimas in May 2008 in Negros Occidental Province were incubated by Bruno Kneubühler in Switzerland.

[2] Trachyaretaon negrosanon is easy to feed in the terrarium with the leaves of bramble, hazel, rhododendrons, ivy or beech.

To enable egg laying, the bottom of the terrarium should be covered a few centimeters high with a slightly moist substrate of soil.
