A new stick insect of the genus Orthomeria Kirby, 1904 (Phasmatodea, Aschiphasmatidae) is described from the Philippines. Orthomeria (Orthomeria) kangi sp. n. is readily distinguished from all other congeners by the distinctive blood red colouration of the costal region of the hind wings. Major features of the external morphology of adults, eggs, and first-instar nymphs are illustrated. Locomotory attachment pads are of the smooth type with irregular microgrooves on the contact surface. An unusual condition of male terminalia is the absence of tergal thorn pads on segment 10. The male clasping organs are represented by an elongated vomer terminating in a prominent spine, and by incurved cerci featuring a bilobed apex equipped with a sharp blade-like ridge. Intraspecific variation in body colouration and hind wing length occurs in females. The new species lives at 400-650 m elevation in the surroundings of the Sablang and Tuba regions, in the Benguet Province of Luzon island. Host plants include Ficus spp. (Moraceae), and Pipturus spp. and Leucosyke spp. (Urticaceae). Observations on the mating and defensive behaviour are presented. Orthomeria (Orthomeria) catadromus (Westwood, 1859) is recognised as a junior synonym of Orthomeria (Orthomeria) pandora (Westwood, 1859), syn. n. A lectotype is designated for both species. Finally, an updated identification key to the species of the subgenus Orthomeria is provided.
2023年，一种新的直翅目昆虫（Phasmatodea，Aschiphasmatidae）被描述于菲律宾。新物种Orthomeria (Orthomeria) kangi sp. n. 很容易通过后翅前缘脉区域独特的血红色与所有其他同属物种区分开来。文中展示了成虫、卵和一龄若虫的主要外部形态特征。运动附着垫为光滑型，接触表面有不规则的微槽。雄性外生殖器的一个不寻常特征是第10节背板上没有刺垫。雄性抱握器官由一个细长的犁骨组成，末端有一个突出的刺，还有弯曲的尾须，其顶端有双叶，配备有锋利的刀片状脊。雌性个体存在体色和后翅长度的种内变异。新物种生活在吕宋岛本格特省萨布朗和图巴地区周围海拔400 - 650米的地方。寄主植物包括榕属植物（桑科）、艾麻属植物和岛艾麻属植物（荨麻科）。文中还介绍了交配和防御行为的观察结果。Orthomeria (Orthomeria) catadromus (Westwood, 1859) 被认定为Orthomeria (Orthomeria) pandora (Westwood, 1859) 的次异名，新组合。为这两个物种指定了一个选模。最后，提供了Orthomeria亚属物种的最新鉴定检索表。
