Pylaemenes konchurangensis females have granular tubercles on the posterior, lateral aspect of the fourth tergite of the abdomen.

The almost uniformly brown colored males are about 41 millimetres (1.6 in) long and significantly smaller and slimmer than the females.

[1][2] George Ho Wai-Chun described the species in July 2018 as Pylaemenes konchurangensis based on two females and one male found by Alexei V. Abramov from Russia in September 2011 at an altitude of 1,020 metres (3,350 ft) in Kon Chu Rang Nature Reserve about 40 km north of K’ Bang Town in the Vietnamese Gia Lai province.

The females are deposited at the Manchester Museum and the male at the collection of Hong Kong Entomological Society.

[1][2] As part of the description of six new Orestesspecies from Vietnam, Joachim Bresseel and Jérôme Constant established a new differentiation between the genera Pylaemenes and Orestes in January 2018, which was confirmed in 2021 by genetic analysis.

[3][4] As of 2019/2020, a sexual stock collected by Bresseel and Constant in Kon Plông district is in breeding.

Because the animals in both sexes closely resemble the description of Pylaemenes konchurangensis, Bresseel named them Orestes cf.
