Males are around 35 to 43 millimetres (1.4 to 1.7 in) long and, typical of the genus, medium to dark brown in color.

The species-specific spines located in front of and behind the eyes on the head are pronounced as follows (see also Acanthotaxy of Heteropterygidae).

Behind each eye, a distinct edge (postocular carina) extends backwards, where it ends in a conical tubercle.

Characteristic is an elongated, strongly tapering ridge medial on the posterior ninth tergite of the abdomen.

Also typical of the species are two laterally compressed and rounded teeth on the distal, outer abdominal ridges of the middle and hind legs.

[1] The species is so far only known from the Thừa Thiên-Huế province in central Vietnam, where it was found in the Bạch Mã National Park and near a station of the Vietnam National Museum of Nature in the Phong Điền district.

1 'Ba Be' Orestes bachmaensis Joachim Bresseel and Jérôme Constant found several males and females of this species in the Bạch Mã National Park on July 15 and 16, 2011.

In 2015 Bresseel and Constant collected similar animals in the Ba Bể National Park.

These animals are representatives of an as yet undescribed sister species of Orestes bachmaensis, as initial genetic studies show.

It was distributed by the Dutch - Belgian working group Phasma and goes back to animals introduced by Joachim Bresseel and Jérôme Constant in 2011 from the Bạch Mã National Park in Vietnam.

In order to ensure the necessary humidity for the animals and their eggs, a layer of always moist soil is suitable as a substrate.
