In egg-laying adult females, the abdomen in the middle is clearly thickened in height and width and thus almost circular in cross-section.

[2][3][4] In contrast to Aretaon species, those of the genus Trachyaretaon lack the clear spines in the front area of the mesonotum.

Unlike the representatives of the genera Brasidas and Obrimus are found in them in the metasternum neither holes nor pits nor noticeable slits.

In addition, representatives live on the Visayas Islands, more precisely on Negros and Panay.

[6] In 2005 Ireneo L. Lit, Jr. and Orlando L. Eusebio described Trachyaretaon carmelae, the largest species of the genus to date.

Already in 2003 animals were found on the neighboring island of Calayan, which were described by Oskar V. Conle and Frank H. Hennemann as Trachyaretaon brueckneri in 2006.

[1][8][10][11] In May 2008 Jeffebeck Arimas collected specimens from the volcanoes Kanlaon and Mandalagan on Negros Island, which were initially known as Trachyaretaon sp.

In 2021 published genetic analysis carried out on the phylogeny of the Heteropterygidae show that this species does not belong to Trachyaretaon.

A short time later, specialists such as Joachim Bresseel assumed that this species was not a member of the genus Trachyaretaon, but rather the Mearnsiana bullosa described in 1939.

They form the basis of a parthenogenetic breeding line which was initially called Trachyaretaon sp.

[7] Also on Luzon, more precisely in the more southern province Nueva Vizcaya near the Imugan Falls, local naturalists found females from a very similar population at two independent locations.

[8] An initially undescribed species was discovered in 2009 by Bresseel also on Luzon in Aurora province near the city of San Luis at the waterfalls of Cunayan and Ditumabo.

The incorrect classification was recognized a little later and so the stock was in circulation for a long time under the name Trachyaretaon sp.

In April 2010, Bresseel, Tim Bollens and Rob Krijns collected an adult female in Marinfata on the road to Infanta in Quezon province on Luzon.

[16] Both breeding lines were identified by Hennemann as representatives of the same species, which he described in 2023 as Trachyaretaon bresseeli.

They willingly feed on various forage plants such as bramble, hazel, firethorn and ivy.
