Pseudopsyra is a genus of Phaneropterinae katydid (Orthoptera: Tettigoniidae), currently comprising of four species - two species each from southern China and Peninsular Malaysia (Hebard, 1922; Liu & Kang, 2006; Tan & Kamaruddin, 2013, 2014). The revision of Pseudopsyra by Liu & Kang (2006) provided a redescription of the genus, a new diagnosis and a key to known species. Subsequently, more surveys were conducted in Peninsular Malaysia and yield another species, representing the lowest latitudinal limits of this genus thus far (Tan & Kamaruddin, 2013). Continued surveys between the upper and lower latitudinal limits of the genus yield a new species: Pseudopsyra taksini sp. nov. from the Sakaerat Biosphere Reserve, Thailand. The orthopteran diversity at Sakaerat Biosphere Reserve remains understudied with numerous new species described recently, including other genus of Phaneropterinae (Tan & Artchawakom, 2014; Tan et al., 2015). With emphasis of using sexual parts for evidence of reproductive isolation in species delimitation, the discovery of a new species of Pseudopsyra also represents the first record of the genus from Thailand. It is not surprising that more undescribed species of Pseudopsyra can be found across the Indo-China region.
拟伪叶螽属是伪叶螽亚科螽斯（直翅目：螽斯科）的一个属，目前包括四个物种——中国南方和马来西亚半岛各有两个物种（赫巴德，1922年；刘&康，2006年；谭&卡玛鲁丁，2013年、2014年）。刘&康（2006年）对拟伪叶螽属进行的修订提供了该属的重新描述、新的诊断以及已知物种检索表。随后，在马来西亚半岛进行了更多调查，并发现了另一个物种，这代表了该属迄今为止的最低纬度界限（谭&卡玛鲁丁，2013年）。在该属的纬度上限和下限之间持续进行的调查产生了一个新物种：来自泰国沙格叻生物保护区的塔氏拟伪叶螽（Pseudopsyra taksini sp. nov.）。沙格叻生物保护区的直翅目多样性仍未得到充分研究，最近描述了许多新物种，包括伪叶螽亚科的其他属（谭&阿查瓦科姆，2014年；谭等人，2015年）。由于在物种界定中强调使用性器官作为生殖隔离的证据，拟伪叶螽新物种的发现也代表了该属在泰国的首次记录。在印度支那地区发现更多未描述的拟伪叶螽物种也就不足为奇了。
