Pylaemenes mitratus is a species of stick insects (Phasmatodea) native to Malay Peninsula and Sumatra.

Both sexes have a greatly enlarged and raised vertex structure on the head, which is formed from the rear head spines and the front edges of which converge towards the back and upwards in the shape of an inverted V. The supraantennas form a pair of laterally compressed spines in front, which are more prominent in males.

Characteristic, at least for the females, is a conspicuous white spine on the upper side of the mesofemurs and two more on the metafemurs about a third away from the body.

[2][3] The species occurs throughout Malay Peninsula from Perak and Kelantan in the north to Singapore in the south.

[3][4][5] The distribution of Pylaemenes mitratus on Sulawesi, as mentioned by Redtenbacher in the species description,[2] is doubted by later authors.

It was collected in 1902 by Albert Grubauer in Perak on the Malay Peninsula and later determined to be the lectotype of the species.

The specimens from the museum in Genoa mentioned by Redtenbacher are a male and a female, which were collected in May or June 1894 by Elio Modigliani on Sumatra.

They were recognized in 2018 by Francis Seow-Choen as representatives of an as yet undescribed species and re-described together with a male holotype and other paratypes as Pylaemenes longispinus.

In contrast to most other Datamini, hazel, bramble or other Rosaceae are not suitable as fodder plants in the long term.
