چکیده

اعضای جنس زیرزمینی 1849Schiödte,  Niphargus در آب‌های زیرزمینی و یا آب‌های مرتبط با محیط‌های زیرزمینی نظیر چشمه‌ها زندگی می‌کنند. اعضای این گروه یکی از غنی‌ترین جنس‌های دوجورپایان آب شیرین از نظر تعداد گونه (بیش از 300 گونه و زیر گونه) در جهان هستند که در غرب پاله آرکتیک پراکنش دارند. ایران به ­عنوان محدوده شرقی جنس Niphargus مشخص می‌شود و تاکنون 17 گونه از این جنس در ایران یافت شده است که به‌جز گونه N. valachicus، سایر گونه‌ها بومی ایران می‌باشند. در این مطالعه، تنوع و پراکنش اعضای این جنس در ایران و صفات تشخیصی مهم هر گونه بررسی و ثبت جدیدی از گونه N. hosseiniei در اطراف روستای بیلوار شهر کرمانشاه گزارش می‌شود. نقشه توزیع جغرافیایی گونه‌ها با نرم ­افزار Arc GIs  ترسیم گردید. اکثر گونه‌های این جنس از ایران در 5 سال گذشته معرفی شده‌اند و انتظار می‌رود در آینده‌ای نزدیک گونه‌های بیش­تری به فون زیرزمینی ایران اضافه گردد.

چکیده [English]

The members of the subterranean genus Niphargus Schiödte, 1849 live in subterranean waters or waters related to subterranean environments, such as springs. This group is one of the most species-rich genera (more than 300 species and subspecies) among freshwater amphipods in the world, distributed in the Western Palearctic. Iran has been recognized as the easternmost border of the genus Niphargus. Until now, there have been 17 species recorded from Iran; of these only one species was found outside Iran (N. valachicus), all other species are endemic to the country. In this study, the diversity and distribution of the Iranian niphargids are surveyed and contributions are made to diagnostic characters for each species and one new record of N. hosseiniei in Bilvar village in Kermanshah Province is reported. The distribution map of species localities were created using Arc GIs. Noteworthy, most of the Iranian species were described during the past five years and additional species descriptions can be expected to the subterranean fauna of Iran in a near future.
