Abstract AR
تم تشخص أفراد النوعين Pristina longiseta و P.
macrochaeta في عينات من الطحالب الخيطية bryophyte المأخوذة من مناطق المياه الضحلة على جانبي نهر العسافية المرتبط مع شط العرب و هذا هو التسجيل الأول لهذين النوعين في العراق.
وصفت الخصائص المظهرية لهذه الديدان و كان من أهم هذه الخصائص وجود الأهلاب الظهرية التي تتواجد ابتداء من الحلقة الثانية بالنسبة للنوع P.
longiseta و ابتدءا من الحلقة الرابعة بالنسبة للنوع P.
macrochaeta.
و تكون أهلاب الحلقة الثالثة أكبر طولا من بقية الأهلاب بالنسبة للنوع الأول و تسمى بالأهلاب العملاقة giant setae.
يظهر الفص الأمامي المسمى قبل الفم Prostomium بشكل واضح و الذي يمتد مكونا الخطم Proboscis، أما التكاثر فيتم من خلال الانقسام لعرضي أو ما يسمى بالتبرعم Paratomy.
Abstract EN
Individuals of the two species of oligochaetes: Pristina longiseta and P.
macrochaeta were identified from samples of bryophyta from shallow water areas at Al-Assafia creek which is connected to Shatt Al-Arab River.
This is the first report of the two species in Iraq.
The characteristic features of the two species were studied, the first important of these is the presence of dorsal setae, from the second segment in P.
longiseta and from the fourth segment in P.
macrochaeta.
The setae of the third segment in P.
longiseta are longer than the others and called giant setae.
There is a conspicuous Prostomium which extends to form proboscis.
Reproduction is by transverse fission which is called Paratomy.
