Tisamenus draconina is a species of stick insect in the family Heteropterygidae native to the Philippines. Description The species is elongated and is described as the spiniest of the genus. Females reach a length of , males are long. The triangle on the mesonotum typical of the genus is flat and ends, as in Tisamenus lachesis, with interposterior mesonotal spines. The two front angles of the triangle in compound spines forming a toothed crest, the largest element of which is slightly removed from the actual angles. A pair of median metanotals, that is, middle spines on the metanotum, are present. The side edges of the meso- and metanotum are reinforced with long spines. There are only four spines on each side of the mesonatal margins, while there are usually five in similar species. On each side of the metathorax there is a lateral spine and a very large supraoxal spine, i.e. a spine located above the coxa. In contrast to many other Tisamenus species, Tisamenus draconina lacks median spines on the upper surface of the anterior segments of the abdomen. Instead, there are only flat nodules or tubercles here. A spine is attached to each side of the first four abdominal segments, with the front spines being longer and more pronounced than the rear ones. Distribution While the first description only mentions the Philippines as a distribution area, James Abram Garfield Rehn and his son John William Holman Rehn specify this and state the sub-province of Apayao on Luzon as the locality of the eight specimens they examined. The localities of Taiwan and Borneo seem doubtful. Taxonomy John Obadiah Westwood described the species in 1848 under the basionym Phasma (Pachymorpha) draconinum and depicts a female. As early as 1859 he transferred it to the genus Acanthoderus established by George Robert Gray in 1834. Carl Stål names the species in 1875 as belonging to the genus Tisamenus described by him. However, in the combination of the generic and species names, he only names the newly described Tisamenus serratorius and Acanthoderus deplanatus, also described by Westwood, abbreviated as T. deplanato (today Tisamenus deplanatus) and counts Acanthoderus draconinus Westw. only at the end as belonging to this genus. While William Forsell Kirby followed this assignment in 1904 and named the species for the first time in combination with the genus name, Josef Redtenbacher 1906, Lawrence Bruner 1915 and also Philip Edward Bragg 1995
