Five species of aquatic oligochaetes new to Iran with an updated checklist

Abstract

Only 14 species of aquatic oligochaetes occurring in inland waters of Iran have been recorded until now. Our investigations based on samples collected in 2003 and 2005 revealed the presence of six species, including five new to the fauna of Iran: Haplotaxis gordioides, Dero dorsalis, Pristina breviseta, Embolocephalus velutinus and Psammoryctides albicola. The provided checklist of Iranian aquatic oligochaetes is still very short (19 species). It is mostly represented by common, cosmopolitan species. However, taking into account the large area of the country, its mountainous terrain and peculiar hydrological network, more species may be discovered in the future.

Oligochaetes (Annelida, Clitellata) in the Anzali International Wetland, north-western Iran

“…In Iran of this genus only D. dorsalis Ferronierè, 1899 has been found earlier. Jabłońska and Pesić (2014) just reported this species in a pond located in the city of Nowshahr, Mazandaran Province.…”

“…Ayati 2003;JICA 2005;Charkhabi and Sakizadeh 2006;Akbarzadeh et al 2008;Jafari 2009;Tahershamsi et al 2009;Mirzajani et al 2010;Pourang et al 2010;Jamshidi-Zanjani and Saeedi 2013), there are no data on the species diversity of the Oligochaeta of the region, except the single record of Tubifex tubifex by Pourang (1996). The aquatic Oligochaeta species of Iran are mentioned only in a few papers: Stephenson (1920), Egglishaw (1980), Aliyev and Ahmadi (2010), Ahmadi et al (2011Ahmadi et al ( , 2012, Ardalan et al (2011), Jabłońska andPesić (2014). Until now 19 species of aquatic oligochaetes occurring in inland waters of Iran have been recorded.…”

The threat of a non-native oligochaete species in Iran's freshwater: Assessment of the diversity and origin of Eiseniella tetraedra (Savigny, 1826) and its response to climate change

“…The beginning of studies on aquatic Oligochaeta back in 1920 ( Stephenson, 1920 ) and after about 100 years the Iranian fauna of aquatic Oligochaeta is inadequately known and limited to just a few studies ( Egglishaw, 1980 ; Ahmadi et al, 2012 ; Javidkar et al, 2020 ). Based on previous studies, 20 Oligochaeta species had been verified in Iran up to 2015 ( Jabłońska and Pešić, 2014 ). Considering the area, mountainous landscapes, geographical features, and specific hydrological characteristics of Iran, it seems that there will be an increase in the number of these species in the future.…”

“…Untill now, 35 species of Oligochaetes have been identified from different regions of Iran ( Ezzatpanah et al, 2010 ; Mirmonsef et al, 2011 ; Jabłońska and Pešić, 2014 ; Nazarhaghighi et al, 2014 ; Sanchooli et al, 2019 ; Latif et al, 2020 ). Some molecular surveys have been conducted to clarify whether these species are native or exotic ( Latif et al, 2018 ; Bozorgi et al, 2019 ).…”

The Silent Threat of a Non-native Oligochaete Species in Iran's freshwater: Assessment of the Diversity and Origin of Eiseniella tetraedra (Savigny, 1826) and its Response to Climate Change

“…;Ahmadi et al 2012; Javidkar et al 2019). Based on previous studies, 20 Oligochaeta species have been veri ed in Iran until 2015(Jabłon´ska and Pesˇic´ 2014). Considering the area, mountainous landscapes, geographical features and speci c hydrological characteristics of Iran, it seems that there will be an increase in the number of these species in the future Latif et al (2009).…”
