The identity of the leucosiid crabs, Philyra sagittifera (Alcock, 1896) and P. concinnus Ghani & Tirmizi, 1995, originally described from Pakistan is clarified. Redescription of the lectotype male of Philyra sagittifera (Alcock, 1896) and fresh material of both species collected from the Persian Gulf revealed that these two species show significant morphological differences from the generic characters of Philyra sensu stricto and other allied genera in possessing three broad tuberculated ridges united to form a "broad-arrow" pointing forwards on the carapace, and male G1 with apical process curved, with or without a spatulate tip. Therefore, a new genus Tirmilyra n. gen. is established to accommodate both species.
箭蟹科的 Leucosiid 蟹，Philyra sagittifera (Alcock, 1896) 和 P. concinnus Ghani & Tirmizi, 1995，最初描述于巴基斯坦，其身份已得到澄清。对 Philyra sagittifera (Alcock, 1896) 的模式雄体进行重新描述，并对从波斯湾采集到的这两个物种的新鲜材料进行研究，结果表明，这两个物种在形态上与 Philyra sensu stricto 及其他相关属的属级特征有显著差异，它们的甲壳上有三条宽阔的具结节脊，联合形成一个向前指向的“宽箭头”，雄性第一腹肢 G1 的顶端有弯曲的突起，有或没有匙形末端。因此，建立了一个新属 Tirmilyra n. gen. 来容纳这两个物种。
