Vol.03 (1) 2017 Introduction The species Tabanus nemoralis Meig.1820 belongs to family Tabanidae Latreille 1802, subfamily Tabaninae Loew, 1860. This subfamily comprises about 275 species belong to 72 genera, worldwide distributed, from temperate to subtropical and tropical zones [1], it is known from many parts of the world from Asia including Saudi Arabia, Oman, Jordan, Syria, Kuwait and Turkey[2,3,4] to African including Egypt [5] to Europe including Hungary, Italy, Croatia and United Kingdom [6, 7] to North America including U. S. A. and Mexico [8] and to South America including Brazil, Chile and Colombia [9,10], the Tabaninae are poorly known in the Middle East [11], yet a comprehensive generic description is not available [12]. In Iraq, subfamily Tabaninae was studied by Leclercq (1963) describing 24 horse flies species within four genera and studied by Ahmed (2015) describing species within genera [13,14]. The females of most species feed regularly on nectar, which they need for energy, while blood meals are mainly utilized for Oogenesis by pierce skin and suck blood, while the males have lost their mandibles and feed on nectar and pollen alone [15,16]. The blood – feeding behavior of the females of horse flies make their veterinary and medical important, and includes many species important to human and animal health, either by acting as a disease vector such as surra, anthrax and Loaloa, or by debilitating the host [17, 18]. Members of family Tabanidae are medium – sized to larger specimens, usually densely haired on thorax and abdomen. Predominant specimens with brownish side markings on anterior abdominal segments, or mostly grayish – black to black, sometimes with paler dusted and pubescent posterior margins of abdominal segments [19,20]. Compound eyes in living specimens are mostly greenish with three purple bands, only very rarely unbanded or with one or two bands [20]. Eyes are always pubescent, usually rather long and very densely, or the hairs only indistinctly visible in the female sex. Males with longer and more densely haired eyes, facets on the upper parts of eyes either more or less enlarged or sharply separated from lower part with small facets, or all facets almost equal in size [21]. Ocellar tubercle is always present in both sexes, and vertex sometimes with three small vestigial ocelli. Frons usually narrower, frontal calli well developed; median callus usually liner and connected with a larger circular, square to rectangular shaped lower callus; only exceptionally calli reduced or missing. Wings are clear or slightly clouded especially interiorly, rarely with darker patches on cross veins and bifurcations; exceptionally a very short appendix to vein R4 [2,22]. Materials and Methods Specimens of Tabanus nemoralis were collected from Al-Radwania 2014, west of the capital Baghdad, located at longitude 44.2680355 and latitude 33.1863567; and Al-Yousfia 2014, south of the capital Baghdad and away 25 km from Baghdad, located at longitude 44.251662 and latitude 33.07908 [23]. A total of two localities in the East of Iraq were visited during May, June, July and August 2014. Horse flies were trapped with chemical trap and a regular insect net. Samples collected by the above traps were fixed on thick paper and kept in insect box. Date and place of collection and hosts were recorded. A total of four female specimens were identified based on [20 and 22]. The study was made using a dissecting microscope (Olympus, Japan) and compound microscope (Olympus, Japan), using normal light.
