Abstract

Two new species of the genus Pseudachorutes, namely P. hyrcanicus sp. nov. and P. kurdistanicus sp. nov., are described based on materials from different parts of Iran. P. hyrcanicus sp. nov. seem to be especially similar to Pseudachorutes dubius Krausbauer, 1898 and Pseudachorutes vitalii Kaprus Weiner, 2009, two congeners with the same labral formula (4/2,3,4), shape of apical bulb (trilobed) and details of chaetotaxy (unpaired chaeta d1 present and a0 absent on head, a2 chaeta absent on Tht. II and III, m row chaetae present on Abdt. IV, tibiotarsi I-III with 18, 18, 17 chaetae respectively), but are distinguished by the number of chaetae on Tht. I (4+4 in P. dubius, 3+3 in P. vitalii and P. hyrcanicus sp. nov.) and Abdt. IV (11+11 in P. dubius and P. hyrcanicus sp.nov. and 14(15) + 14 in P. vitalii), number of teeth at mandible (two in P. dubius and P. vitalii and four in P. hyrcanicus sp.nov.) and claw (lateral teeth present in P. dubius and P. vitalii and absent in P. hyrcanicus sp.nov.). Pseudachorutes kurdistanicus sp. nov. is related to P. laricis Arbea Jordana,1989 and P. vasylii Kaprus Weiner, 2009 because of the same type of chaetotaxy of head (d1 chaetae present and a0 chaeta absent), Tht. I (3+3 chaetae), Tht. II-III (without a2 chaeta), Abdt. IV (m row chaetae absent), Abdt. V (a2 and p2 chaetae absent) and the absence of lateral teeth on claws. The last three species differ in number of vesicles in PAO (1112 in P. kurdistanicus sp. nov., 46 in P. vasylii and 7-97-9 in P. laricis), shape of apical vesicle on Ant. IV. (trilobed in P. kurdistanicus sp. nov. and simple or slightly bilobed in the other two species), labral formula (4/2,3,4 in a new species, 2/2,3,3,4 in P. laricis and 2/3,3,4 in P. vasylii) and number of chaetae on tibiotarsi I-III (18, 18, 17 in a new species and 19, 19, 18 in the other two species). An identification key of the species of Pseudachorutes recorded so far from Iran is given.

摘要

基于来自伊朗不同地区的材料，描述了两个新的 Pseudachorutes 属物种，即 P. hyrcanicus sp. nov. 和 P. kurdistanicus sp. nov.。P. hyrcanicus sp. nov. 似乎特别类似于 Pseudachorutes dubius Krausbauer, 1898 和 Pseudachorutes vitalii Kaprus Weiner, 2009，这两个近缘种具有相同的唇基公式（4/2,3,4）、顶端球部的形状（三叶状）和毛序细节（头部无单生毛 d1，Tht. II 和 III 无 a2 毛，Abdt. IV 有 m 行毛，胫节 I-III 分别有 18、18、17 根毛），但通过 Tht. I（P. dubius 为 4+4，P. vitalii 和 P. hyrcanicus sp. nov. 为 3+3）和 Abdt. IV（P. dubius 和 P. hyrcanicus sp. nov. 为 11+11，P. vitalii 为 14(15)+14）的毛数、颚齿（P. dubius 和 P. vitalii 为 2 个，P. hyrcanicus sp. nov. 为 4 个）和爪（P. dubius 和 P. vitalii 有侧齿，P. hyrcanicus sp. nov. 没有）来区分。Pseudachorutes kurdistanicus sp. nov. 与 Pseudachorutes laricis Arbea Jordana,1989 和 Pseudachorutes vasylii Kaprus Weiner, 2009 有关，因为它们的头部毛序（d1 毛存在，a0 毛不存在）、Tht. I（3+3 根毛）、Tht. II-III（无 a2 毛）、Abdt. IV（m 行毛不存在）、Abdt. V（a2 和 p2 毛不存在）和爪上没有侧齿相同。后三个物种在 PAO 中的囊泡数（P. kurdistanicus sp. nov. 为 1112，P. vasylii 为 46，P. laricis 为 7-97-9）、Ant. IV 上的顶端囊泡形状（P. kurdistanicus sp. nov. 为三叶状，其他两个物种为简单或稍二叶状）、唇基公式（P. kurdistanicus sp. nov. 为 4/2,3,4，P. laricis 为 2/2,3,3,4，P. vasylii 为 2/3,3,4）和胫节 I-III 的毛数（P. kurdistanicus sp. nov. 为 18,18,17，其他两个物种为 19,19,18）有所不同。给出了迄今为止记录在伊朗的 Pseudachorutes 属物种的鉴定钥匙。
