Re-examination of the holotype of Dermacentor atrosignatus Neumann, 1906 (Acari: Ixodidae) stored in the Natural History Museum (London, UK) revealed that this taxon is identical with D. auratus Supino, 1897 and should be treated as a junior synonym of the latter species. A correct name for the distinct species previously identified as D. atrosignatus Neumann, 1906 sensu Wassef & Hoogstraal, 1984 should be D. tricuspis (Schulze, 1933) n. comb., n. stat. Adults of D. tricuspis are redescribed here. Re-examination of extensive holdings of Oriental Dermacentor Koch, 1844 ticks stored in the United States National Tick Collection revealed that a morphologically distinct new species of this genus, namely D. falsosteini D. Apanaskevich, M. Apanaskevich & Nooma n. sp. should be recognized. Adults of D. tricuspis and D. falsosteini n. sp. can be distinguished from other species of Oriental Dermacentor and each other by the colour pattern of the conscutum and scutum, the pattern of punctations on the pseudoscutum and scutum, the shape of female genital structures and spurs on coxa I. Dermacentor tricuspis is recorded from Indonesia, Malaysia, the Philippines and Thailand where the adults were mostly collected from various species of wild pigs (Artiodactyla: Suidae) and vegetation; few adults were available from other mammals (Artiodactyla: Bovidae; Carnivora: Canidae, Felidae, Ursidae; Pholidota: Manidae), as well as humans and reptiles (Squamata: Elapidae, Varanidae). One male was reared from a nymph collected on a rodent (Rodentia: Muridae). Dermacentor falsosteini n. sp. is found in Indonesia, Malaysia and Thailand where the adults were collected from bearded pig, Sus barbatus Müller, wild boar, S. scrofa Linnaeus, unidentified wild pig, Sus sp. (Artiodactyla: Suidae), Malayan tapir, Tapirus indicus Desmarest (Perissodactyla: Tapiridae), human and vegetation.
重新检查保存在英国自然历史博物馆（Natural History Museum，London，UK）的 Dermacentor atrosignatus Neumann，1906（蜱螨目：硬蜱科）的模式标本，结果表明该分类单元与 D. auratus Supino，1897 完全相同，应被视为后者的同物异名。先前被鉴定为 Dermacentor atrosignatus Neumann，1906（Wassef & Hoogstraal，1984）的独特物种的正确名称应为 Dermacentor tricuspis（Schulze，1933）n. comb.，n. stat.。本文重新描述了 D. tricuspis 的成虫。重新检查保存在美国国家蜱虫收藏中的大量东方硬蜱 Dermacentor Koch，1844 标本，发现该属的一个形态独特的新物种 Dermacentor falsosteini D. Apanaskevich，M. Apanaskevich & Nooma n. sp. 应该被识别。D. tricuspis 和 D. falsosteini n. sp. 的成虫可以通过盾片和背板的颜色模式、假盾片和背板上的点纹模式、雌性生殖器结构的形状和股节 I 上的刺来与其他东方硬蜱物种和彼此区分开来。Dermacentor tricuspis 分布于印度尼西亚、马来西亚、菲律宾和泰国，其成虫主要从各种野猪（偶蹄目：猪科）和植被中采集；从其他哺乳动物（偶蹄目：牛科；食肉目：犬科、猫科、熊科；鳞甲目：树懒科）、人类和爬行动物（有鳞目：眼镜蛇科、巨蜥科）中采集到的成虫较少。一只雄虫是从采集自啮齿动物（啮齿目：鼠科）的若虫中饲养的。Dermacentor falsosteini n. sp. 分布于印度尼西亚、马来西亚和泰国，其成虫采集自须猪，Sus barbatus Müller，野猪，S. scrofa Linnaeus，未鉴定的野猪，Sus sp.（偶蹄目：猪科），马来貘，Tapirus indicus Desmarest（奇蹄目：貘科），人类和植被。
