03C54558BD24FFF01498FF270CE8F954.taxon	discussion	Discussion and remarks. Our molecular results support the specific position for the populations described here as I. hyrcanicus sp. nov. There is no genetic difference between color forms of the new species and intraspecific divergences is 0.3 % (Fig. 1, Table 2). The genetic divergence between I. hyrcanicus sp. nov. and the other species of the genus is ranging from 22.4 % to 29.8 % for COI (Table 2) which is similar to the divergence found among previously described species (ranging from 22.0 % to 33.3 %; Table 2). The genetic divergence between I. hyrcanicus sp. nov. and two other species of Isotomurus is 28.4 and 27.9 for 28 S gene (Table 3). Isotomurus hyrcanicus sp. nov. belongs to the group of species without setae on mucro, with 3,3,1 Trich. on Abd. II, III and IV, and with 3 + 3 laterodistal setae on VT. Main differences between I. hyrcanicus sp. nov. and these species are summarized in Table 1. The new species is closely related to I. palustris which can be separated by the number of setae on Ret. (14 – 37 in I. palustris against 10 – 13 in I. hyrcanicus sp. nov.). Genetic divergence between the new species and I. palustris is 29.8 % for COI gene which is in the range of genetic difference between other Isotomurus species. The new species resembles I. pseudopalustris. They can be separated by different number of basomedian setae on labium (8 – 12 basomedian setae in I. pseudopalustris against 12 – 14 setae in I. hyrcanicus sp. nov.). The new species is close to I. unifasciatus which has modified male setae on Abd. III and IV (absent in I. hyrcanicus sp. nov.). Genetic divergence between the new species and I. unifasciatus is 24.4 % for COI gene. ...... continued on the next page	en	LAFOORAKI, ELHAM YOOSEFI, HAJIZADEH, JALIL, SHAYANMEHR, MASOUMEH (2023): A revision of the genus Isotomurus (Collembola: Isotomidae) in northern Iran using molecular evidence.

03C54558BD21FFFE1498F99C0FF0FE0A.taxon	discussion	Discussion and remarks. Results of the molecular analyses confirm the specific status for population which is described here as a new species. The genetic divergence between I. katule sp. nov. and the other species of the genus is ranging from 12.3 % to 33.1 % (Table 2). The new species is related to Isotomurus species with 3,3,1 Trich. on Abd. II, III and IV, 3 + 3 laterodistal setae on VT, and uniform body color. Main differences between I. katule sp. nov. and these species are summarized in Table 1. The new species is close to I. italicus. Apart from above mentioned characters, their body size is similar (less than 2 mm). But they can be distinguished by different macrosetae on abdomen (long and strongly ciliated in I. katule sp. nov. and short and smooth in I. italicus), different number of setae on Ret. (8 – 10 in I. italicus and 5 – 8 in I. katule sp. nov.), PAO to ocellus ratio (1.4 in I. italicus and 1.0 in I. katule sp. nov.), and modified male setae (present on Abd. IV in I. italicus and absent in I. katule sp. nov.). They differ in ecology: I. italicus is collected often in disturbed habitats like gardens and farmlands which are not very wet (Fjellberg, 2007), while I. katule sp. nov. lives in deep forests along water. The new species is near to I. fucicola by presence of 3 + 3 laterodistal setae on VT, long ciliated Mac. on abdomen, uniform body color, and similar habitats. They can be separated by different number of setae on Ret. (8 – 11 in I. fucicola and 5 – 8 in I. katule sp. nov.), PAO to ocellus ratio (1.5 in I. fucicola and 1 in I. katule sp. nov.), body size (1.7 – 2.5 mm in I. fucicola and 1.18 – 1.48 mm in I. katule sp. nov.), and modified male setae (present on Abd. III and IV in I. fucicola and absent in I. katule sp. nov.). Genetic divergence among them is 28.0 % for COI gene (Table 2). Isotomurus katule sp. nov. is closely related to I. graminis. They can be distinct by body size (more than 2.5 mm in I. graminis and less than 1.5 mm in I. katule sp. nov.), and modified male setae (present on Abd. III and IV in I. graminis and absent in I. katule sp. nov.). They are different ecologically and genetically. I. graminis usually inhabits in humid open grasslands and is rare in forests and along waters, in contrast, I. katule sp. nov. can be found along water in forest. Genetic divergence among them is 29.9 % for COI gene (Table 2). The new species is related to I. cassagnaui. They share body size less than 1.5 mm, PAO to ocellus ratio near 1, 5 setae on Ret., and few basomedian setae (about 5) on labium. Both species are found near water. They differs in modified male setae (present on Abd. III and IV in I. cassagnaui and absent in I. katule sp. nov.), blue spots on lateral sides of Abd. VI (present in I. cassagnaui and absent in I. katule sp. nov.), antennal segment ratio I: II: III: IV (1: 0.6: 0.60: 0.50 in I. cassagnaui and 1: 0.47: 0.40: 0.34 in I. katule sp. nov.), Mac. on abdomen (relatively short and not densely ciliated in I. cassagnaui and long and strongly ciliated in I. katule sp. nov.). The genetic divergence between them is 23.1 % for COI gene which supports that our specimens are a different species. This species is likely mixed up with other species with uniform body color in previous records.	en	LAFOORAKI, ELHAM YOOSEFI, HAJIZADEH, JALIL, SHAYANMEHR, MASOUMEH (2023): A revision of the genus Isotomurus (Collembola: Isotomidae) in northern Iran using molecular evidence.

03C54558BD2DFFFF1498FF6F0FB1FDC2.taxon	discussion	Remarks. The species has been reported from northern parts of Iran by some researchers (Cox 1982, Hosseini et al. 2016). It seems that this species is mixed up with I. hyrcanicus sp. nov. in records of the old authors because of identical color pattern. During our investigation of Isotomidae in southern parts of Caspian Sea (North of Iran), we could not find I. palustris. The specimens of this species were only recorded from a greenhouse in Esfahan province (central Iran). This European species is probably introduced by human via soil transportation.	en	LAFOORAKI, ELHAM YOOSEFI, HAJIZADEH, JALIL, SHAYANMEHR, MASOUMEH (2023): A revision of the genus Isotomurus (Collembola: Isotomidae) in northern Iran using molecular evidence.
