Hammamurad Nabeel A. Mawlood College of Agriculture College of Agriculture Salahaddin University Salahaddin University Received: 04/05/2015 Accepted: 02/06/2015 Abstrac The present work includes a details description of three species of Clytra Laicharting from Kurdistan Region – Iraq. The species was collected from some plants during the period of April tile July - 2013. Important body parts such as Labrum, Pronotum and male genitalia were illustrated and drawing. Localities, date of collection and plant hosts were mentioned. Introduction lytrinae is one of very important subfamily of Chrysomelidae contains 1500 species of 62 genera belonging to six tribes in the world, it consists of 38 genera in one tribe, C Clytini in the Palearctic region (Seeno and Wilcox, 1982). The genus Clytra increased to include 56 species, six varieties and 21 aberrations, as shown in the catalogue of Clavareau (1913). Fundamental progress was made in the taxonomy of the genus due to the following works: Lopatin (1962), Daccordi and Petitpierre (1977), Tan (1992). Lopatin (1984) reported the genus Clytra consist of 50 species in old world and 16 species in palearctic region. Kasap (1987) indicated the list of Clytrinae represented seven species in Turkey, Labidostomis Chevrolat, Tituboea Lacordaire, Lachnaia Dejean, Clytra Laicharting, Smaragdina Chevrolet, Part of MSc. thesis for the first author Cheilitoma Dejean and Coptocephala Chevrolet. Lobl and Smetana (2010) recorded 175 species in palearctic region. In Iraq there are not any taxonomic study of the subfamily species except Derwesh (1963) listed five species of Clytridae Clytra nigrocincta Lacordaire, C. novempunctata Olivier, Gynandrophthalm aunipunctata Ol., Labidostomis longimana L. and L. rufa (Waltl). Derwesh (1965) mentioned 11 species of Clytridae includes, Clytra nigrocincta Lacordaire, C. novempunctata Olivier, C. valeriana Menetries, Coptocephala unifasciata Scop., Gynandrophthalm aunipunctata Ol., Labidostomis decipiens Faldreman, L. longimana (Linnaeus), L. propiqua Ol., L. rufa (Waltl), Melitonoma sp., and Tituboeama cropus Ill. Abdul- Rassoul (1976) recorded two species Clytra nigrocincta Iacordaire and Gynandrophthalma unipunctata Olivier. Al-Ali (1977) recorded six species of the family, Clytra nigrocincta Lacordaire, Coptocephala unifasciata (Scop.)., Gynandrophthalma unipunctata Ol., G. viridana Lac., Labidostomis longimana (Linnaeus), and L. propinqua (Fald.). Materials and Methods The specimens were collected from the period of April tile July 2013 from the flowers of some plants in different localities of Kurdistan region - Iraq. The specimens were placed in boiling water for 10-15 minutes to soften their parts. Then the parts were separated and put in 10% KOH which placed in water bath for 10-15 minutes; after that placed in distilled water for 2-3 minutes. The parts are placed in ethyl alcohol 25% and dissected under microscope, then transferred to ethyl alcohol 50%, 75% and 100% respectively for two minutes of each concentrations, then placed in xylol for two minutes, for translucency, finely placed in Canada 31 Vol.27, No.5, 2015 Zanco Journal of Pure and Applied Sciences Vol.27, No.5, 2015 balsam to support slides for subsequent examination under microscope (Aslan and Warchalowski, 2000) .The species were identified by using taxonomic keys of (Hubble, 2010).
