Brasidas is a genus of stick insects that is native to the Philippines and is named after the Spartan general Brasidas[1] The representatives of this genus correspond in the habitus typical representatives of the Obrimini and are similar in appearance to Obrimus species.

In egg-laying adult females, the abdomen in the middle is clearly thickened in height and width.

[3][4] The distribution area of the genus extends to the islands Samar, Luzon, Mindanao, Leyte, Siargao and Rapu-Rapu.

[4] As early as 2004, Oliver Zompro mentioned the need to carry out studies at the species level in order to clarify the status of the genus Euobrimus and Brasidas.

[9] This assumption was confirmed by Sarah Bank et al. research published in 2021 based on genetic analysis to clarify the phylogeny of the Heteropterygidae.

The first species to be introduced in 2002 was Brasidas samarensis, which is listed by the Phasmid Study Group under PSG number 235, but is apparently no longer in breeding.

The breeding stock that is most widespread in terrariums must be correctly called Brasidas lacerta 'Mt.

[7][11][10][12] Additional specimens were later imported (around 2010) from the neighboring province where this breeding line was found, more precisely from the vicinity of Nabunturan.

The same applies to specimens collected in October 2012 by Francis Seow-Choen and Ian Abercrombie near Valencia in the province of Bukidnon.

[13] In October 2011, Thierry Heitzmann, who lives in the Philippines, collected four pairs of another species on the island of Rapu-Rapu.

In 2012, the Swiss Philipp Heller managed to hatch some specimens from these, successfully raise them and pass them on.

[6][7] Even before the summer of 2011, Heitzmann also collected on Luzon in the province of Sorsogon on Mount Pulog animals that are now also classified as Brasidas cavernosus.

[6][7][15][16] While the first-mentioned strain received the PSG number 362 from the Phasmid Study Group and was called Brasidas sp.
