Mawlood and ***M. S. Abdul-Rassoul **College of Edujcatio, Diyala University ***Iraq Museum Natural History, Baghdad University ABSTRACT This research includes a detailed morphological description of the Pollenia mesopotamica sp. nov. in Iraq. Locality, host plant and data of collection were given. INTRODUCTION Pollenia Rob.-Desvoidy is one of the important genera of family Calliphoridae which as conceived at present has more than 100 members vairously distribution in Nearctic, Palaearctic, Oriental and Australian (Dear, 1986; Rognes, 1987). Some species are parasites or Predatores in larval stages on earthworms specially Allolobophora Chiorotica (Savigny) and Lumbricus terrestris L. Seguy (1941) Keyed and illustrated various feature of this species. Taxonomic revision of this genus has been carried out by (Rohdendrof, 1935; Seguy, 1941; Schumann, 1986 and Rognes, 1987, 1992, 1998). Pollenia mesopotomica sp. nov.

Legs: dark brown, with slivery pollen, fore tibia with a row of bristles on anterodorsal surface and 1 bristle on posteroventral surface; mid tibia (fig.2a,b) with 4-3 bristles on each posterodorsal and anteroventral surface; hind tibia with 2 bristles on each anterodorsal and anteroventral surface. Abdomen: black, with silvery pollen, hind margin of tergites with 5-3 bristles; ventral surface of abdomen in male (fig.2c) black, with silvery pollen; first srternite small, nearly cup shaped, second sternite e larger, nearly oval shaped, the third and fourth sternites oval shaped, the sternites 2-4 are with moderate densely of long setae and with 12-8 bristles. Fifth sternites are deeply clefted posteriorly and forming to elongated ovaly lammella which is covered with dense, short moderately length of setae and 6-5 long bristles. Male terminalia: Tergite 6 (fig.2c) black, with 4-3 bristles, sternite 6 (fig.2d) globular shaped, its left arm long and connected firmly to fifth sternite, right arm short and failing to reach to same sternites syntergosternite 7+8 (fig.2e) black, dome shaped with moderate densely bristles, its posterior margine emarginated; hypandrium (sternite 9) reddish, its posterior arms slightly bend, and middle surface with chitinous arch; empandrium (tergite 9) nearly square shaped, its apical half with moderate densely long setae, and its basal half with lowest densely setae; paralobs (fig.3a) nearly cylinderical shaped, with densely ,short bristles; anal cerci (fig.3b) with broad base, united toghter basaly forming V-shape and separated near the one third of apical part, its basal surface with densely and long bristles so that reduced gradually toward its apical part phalloapodeme(fig.3c) oval shaped, 0.66-0.59 mm length, broad from the apical and gradually tapering toward the base, its apical surface with two broad chitinous band; pregonite (fig.3d) hook-like with 7- 6 bristles; postgonite (fig.3e) cylinderical shaped, its ventral surface with 7-6 bristles and one bristle on its inner margin; phallus (fig.3f) 0.98-0.87 length, basiphallus rectangle shaped, 0.17-0.12 length, epiphallus slightly bend, 0.25-0.21 mm length, paraphallus sword shaped, its apical triangle shaped and its outer margin near the apical without teeth, paraphallus process sword shaped, the distance between the basiphallus and paraphallus process is narrow 0.11-0.09mm, hypophallus oval shaped, its outer margin of basal half with very fine tooth. Ejaculatory sclerite (fig.3g) nearly cup shaped, 0.30-0.26mm in length. Pollenia mesopotamica sp.nov. is closely related to P. dasypoda Protschinsky but differs from it by the following: Characters: the dorsal surface of thorax with three humeral bristles and posthumeral bristles; basicosta black; node with 5-4 setae; apical half of epandrium surface with two chitinous arch; one fourth of apical part of paraphallus strongly bended, paraphallus 61 N. A. Mawlood & M. S. Abdul-Rassoul process cylindrical of paraphallus strongly bended, paraphallus process cylindrical shaped, its length is shorter than the phallus. Host plant: Peach, Prunus persica.
