DESCRIPTIVE OSTEOLOGY OF Oxynoemacheilus kermanshahensis (B�n�rescu and Nalbant, 1966) (CYPRINIFORMES, NEMACHEILIDAE)

Descriptive osteology of Paracobitis persa Freyhof, Esmaeili, Sayyadzadeh & Geiger, 2014, an endemic species from Kor River basin of Iran

“…In this species, similar to Oxynoemacheilus kiabii (Mafakheri et al 2014), O. bergianus (Jalili and Eagderi 2014), Sasanidus kermanshahensis (Mafakheri et al 2015), Paraschistura nielseni (Azimi et al 2015a) and P. cristata (Azimi et al 2015b) and P. hircanica (Azimi et al 2014), the junction of the lateral ethmoid is at the anterior margin of the orbitosphenoid; whereas according to Prokofiev (2010), the lateral ethmoid of loaches is stationarily jointed to the supraethmoid-ethmoid.…”

“…There is no preethmoid-I in P. persa, O. kiabii (Mafakheri et al 2014), O. bergianus (Jalili and Eagderi 2014), S. kermanshahensis (Mafakheri et al 2015), P. nielseni (Azimi et al 2015a), P. cristata (Azimi et al 2015b) and P. hircanica (Azimi et al 2014) versus presence of the pre-ethmoid-I in the genera of Lefua, Oreonectes, Yunnanilus, Eonemachilus, Micronoemacheilus, Hedinichthys, Orthrias, and Triplophysa (Prokofiev 2010). The lateral ethmoid is oriented horizontally and its middle part is wider in P. persa, whereas in P. hircanica, it is L-shaped having a process oriented anteriorly (Azimi et al 2014); this process is absent in P. iranica (Nikmehr and Eagderi 2016a).…”

“…There is no sesamoid ossification in P. persa, similar to P. hircanica, but in O. kiabii (Mafakheri et al 2014), O. bergianus (Jalili and Eagderi 2014), S. kermanshahensis (Mafakheri et al 2015) and P. cristata (Azimi et al 2015b), a sesamoid ossification is present. However, according to the Prokofiev (2009Prokofiev ( , 2010, the sesamoid ossifications are present in the members of the genus Paracobitis as well as Dzihunia amudarjensis and Oxynoemacheilus angorae.…”

“…However, in O. kiabii (Mafakheri et al 2014), O. bergianus (Jalili and Eagderi 2014), S. kermanshahensis (Mafakheri et al 2015) and P. nielseni (Azimi et al 2015a), it is present.…”

Gyrodactylus angorae (Monogenea: Gyrodactylidae): First Occurrence on the Body of Two Nemachilid Fishes from Iraq

“…Stone loaches or Nemacheilidae are small fishes found in freshwaters of Asia, Europe, and northeast Africa (Coad 2017). Due to their small size and low economic value, nemachilid fishes are poorly known group of freshwater fishes (Kottelat 2012;Mafakheri et al 2015). The Euphrates and Tigris river drainages are the major hotspot of nemachilid loach species (Freyhof et al 2019).…”
