Four species of the genus were recovered from southern (Bushehr province) and southeastern (Southern Khorasan province) Iran. The first species, n. sp. represents a new member to the genus and is characterised by 4.8-5.6 mm long females with anteriorly flattened lip region separated from the rest of the body by depression, amphidial fovea pocket-shaped without lobes, tail conical, dorsally convex, ventrally almost straight with bluntly rounded tip and males in population. By having similar lip region and tail shape, the new species most closely resembles five species , and . It represents the cryptic form of the last species. The second species belongs to , recovered in both southern and southeastern Iran, representing the first record of the species after its original description. As an update to the characteristics of this species, it's all juvenile developmental stages were recovered and described. The criteria to separate L. mirus from two closely related species, and , are discussed. The third species belongs to , a new record in southern Iran. The fourth species, was recovered in high population density in association with date palm trees in Bushehr province. The phylogenetic relationships of the new species and recovered populations of and were reconstructed using two ribosomal markers and the resulted topologies were discussed.
从伊朗南部（布什尔省）和东南部（南呼罗珊省）共采集到四个属的物种。第一个物种，即新种，是该属的一个新成员，其特征为雌性体长 4.8-5.6 毫米，唇部前段扁平，与身体其他部分通过凹陷分开，口针窝呈口袋状，无裂片，尾部圆锥形，背腹面均凸，腹面几乎直，末端钝圆，雄虫在种群中。新种与五个物种，即 、 、 、 和 ，最相似，具有相似的唇部和尾部形状。它代表了最后一个物种的隐种形式。第二个物种属于 ，在伊朗南部和东南部均有采集，是该物种原始描述后的首次记录。作为对该物种特征的更新，我们描述了所有的幼体发育阶段。讨论了将 L. mirus 与两个密切相关的物种 和 区分开来的标准。第三个物种属于 ，在伊朗南部的一个新记录。第四个物种 ，在布什尔省与枣椰树相关联的高种群密度中被采集到。利用两个核糖体标记对新种和 、 两个种的已采集种群的系统发育关系进行了重建，并对所得拓扑结构进行了讨论。
