Diagnostic characters, a redescription of some of the morphological features, photographs and illustrations are provided for the new record species in this investigation. Keywords: Carabidae, Chlaenius, Ground beetles, Iraq, New Record. INTRODUCTION Beetles are considered the most taxonomical various insect groups that contain major components of ecosystems in terms of biomass; species richness and ecological roles (Stack, 2015). One of the most important families of beetles is ground beetles (Carabidae). This family includes 24 subfamilies, 110 tribes, and more than 40,000 species dating back to 1927 genera described worldwide (Larochelle and Lariviere, 2007). Carabidae members play important roles in pollination, predator-prey interaction, granivore, decomposition and nutrient cycling, and soil disturbances (Huffaker and Gutierrez, 1999). Many members are considered generalist predators, meaning they feed on a wide-range of pests including: aphids, beetle larvae, moth larvae and mites; a few specialists feed on snails (Kromp, 1999). The tribe of Chlaeniini is found in all zoogeographical regions of the world (Hegde and Manthen, 2017). Löbl and Smetana (2003) indicated that there are 860 species and 62 subspecies belonging to the genus Chlaenius in the world, and this genus represents 650 species in Afrotropical and Oriental regions. Among them 20 species were recorded in Iraq: BULLETIN OF THE IRAQ NATURAL HISTORY MUSEUM Iraq Natural History Research Center & Museum, University of Baghdad https://jnhm.uobaghdad.edu.iq/index.php/BINHM/Home Online ISSN: 2311-9799 Print ISSN: 1017-8678 https://doi.org/10.26842/binhm.7.2022.17.1.0033 https://orcid.org/0000-0002-7644-4252 mailto:aamal.hussein1004@coagri.uobaghdad.edu.iq https://creativecommons.org/licenses/by/4.0/ https://jnhm.uobaghdad.edu.iq/index.php/BINHM/Home 34 BULLETIN OF THE IRAQ NATURAL HISTORY MUSEUM Revision of the genus Chlaenius Chlaenius spoliatus (Rossi, 1792), C. syriacus Chaudoir, 1876; C. amarae Andrewes, 1920 (Andrews, 1927); C. festivus (Panzer, 1796) (Roubal, 1932); C. iraqkensis Jedlička, 1959 (Jedlička, 1959); C. coeruleus (Steven, 1809) (Sage, 1961).

The current study aimed to revise and update the information of the species that belong to the genus Chlaenius Bonelli, 1810 in Iraq. MATERIALS AND METHODS The specimens were collected from different localities in the middle of Iraq by hand picking from fields under stones and light trap; the specimens were identified using different taxonomic keys such as Ali (1964, 1966), Lindroth (1974), Arnett and Thomas (2001), Park and Park (2013) and Yaiphabi Chanu and Swaminathan (2017). Synonyms are provided according to GBIF Secretariat (2021). The male genitalia and mouthparts were dissected, examined and photographed by an OPTIKA microscope Italy and Samsung A30S mobile camera. RESULTS AND DISCUSSION In this study, there were 21 species identified that belong to the genus of Chlaenius, one of them (C. hamifer Chaudoir, 1856) was given as a new record for first time in Iraq; these species were revised as follow: Subfamily, Callistinae Tribe, Chlaeniini Genus, Chlaenius Bonelli, 1810 Synonyms: Anomoglossus de Chaudoir, 1856 Aulacosomus Grundmann, 1955 Baidochlaenius Basilewsky, 1950 Barymorphus de la Ferté-Sénectère, 1851 Basilewskyellus Grundmann, 1956 Brachylobus de Chaudoir, 1876 Callistometus Grundmann, 1956 Calochlaenius Kuntzen, 1913 Capsochlaenius Basilewsky, 1950 Chaelinus Basilewsky & Grundmann, 1954 Chaelinus Lucnik, 1933 Chinelaus Basilewsky & Grundmann, 1954 Chinelaus Lucnik, 1933 Chlaeniodromus Basilewsky, 1950 35 BULLETIN OF THE IRAQ NATURAL HISTORY MUSEUM Abdullah and Al-Jassany Chlaenionus Kuntzen, 1913 Chlaeniopus Grundmann, 1955 Chlaeniostenodes Basilewsky, 1953 Chlaeniostenus Kuntzen, 1919 Chlaenites Motschoulsky, 1860 Chlaenitidius Jeannel, 1949 Chlaenius Dejean, 1826 Chloenius Brullé, 1832 Compsochlaenius Alluaud, 1916 Cyaneodinodes Jeannel, 1949 Diaphoropsophus de Chaudoir, 1850 Dibolochilus Lacordaire, 1854 Dilobochilus Ferté-Sénectère, 1851 Epomis Dejean, 1826 Eudinodes Basilewsky, 1965 Eurydactylus Ferté-Sénectère, 1851 Glyptoderus de la Ferté-Sénectère, 1851 Goniodinoides Jeannel, 1949 Iberodinodes Basilewsky & Grundmann, 1954 Iberodinodes Wagner, 1932 Ilaenchus Basilewsky & Grundmann, 1954 Ilaenchus Lucnik, 1933 Laenichus Lucnik, 1933 Leptodinodes Jeannel, 1949 Lissauchenius Macleay, 1825 Lissauchenus Desmarest, 1851-22 Merochlaenius Grundman, 1955 Naelichus Lucnik, 1933 Nectochlaenius Antoine, 1961 Ocybatoides Jeannel, 1949 Ocybatus Laferté-Sénectère, 1851 Ocydromus Laferté-Sénectère, 1851 Oochlaenius Alluaud, 1933 Pachychlaenius Grundmann, 1955 Pachydinodes Kuntzen, 1919 Parachlaenites Jeannel, 1949 Paradinodes Apfelbeck, 1904 Paratrachelus Basilewsky, 1950 Pelasmomimus Grundmann, 1955 Pelasmus Motschoulsky, 1850 Platychlaenius Jeannel, 1949 Prochlaeniellus Basilewsky, 1965 Pseudanomoglossus Bell, 1960 Pseudochlaeniellus Jeannel, 1949 36 BULLETIN OF THE IRAQ NATURAL HISTORY MUSEUM Revision of the genus Chlaenius Randallius Bousquet, 2012 Rhizotrachelus Lacordaire, 1854 Rhysotrachelus Boheman, 1848 Rhyzotrachelus Chaudoir, 1876 Sericochlaenius Grundmann, 1955 Spilochlaenius Jeannel, 1949 Stenodinodes Kuntzen, 1919 Syntelestes Gistl, 1857 Terraleus Fairmaire, 1899 Tomochilus Laferté-Sénéctère, 1851 Trachychlaenites Kuntzen, 1919 Umtalius Péringuey, 1926 Wilmernstus Basilewsky, 1965 Subgenus, Amblygenius LaFerte-Senectere, 1851 Chlaenius (Amblygenius) dimidiatus Chaudoir, 1842 Synonym: Chlaenius Palaestinus Reiche & Saulcy, 1855 World distribution: Iraq (Derwesh, 1965); Argentina, Turkey, Egypt, Syria, India, Turkmenistan and Afghanistan (Löbl and Smetana, 2003); Iran and Palestine (GBIF Secretariat, 2021).

Head and pronotum in dorsal view with strong reddish coppery lustre, Elytra green is covered with thick brown hair and erect, with two yellowish bends. Antennae, mandibles, palpi, labrum, and legs yellowish brown. Head elongated, and convex, dorsal side with punctures, eyes prominent (Pl. 2.A). Clypeus with one normal setae on each side, three basal segments of antenna glabrous and remainder with fine hairs (Pl.2.B); palpi cylindrical shaped. Thorax is wider and longer than the head, pronotum green with strong reddish coppery reflection, slightly convex and with numerous deeply punctures that present denser at the base, also it contains broad and long fovea, the median line is pale, basal angle rounded. Legs: yellowish brown, tarsomeres normal. Hind trochanter elongates and extended, about half the length of the leg, claws are simple. Elytra: length 8.2 mm and width 3.0 mm, reaching to the tip of abdomen with regular intervals, the surface of elytra with small punctuate at the interval, striae with strongly and deeply punctuate, apices of elytra with distinct yellowish comma-like shaped fasciae or spot at interval 3 to 8, that present at apical 1/3 part of elytra (Pl.3.A) and reaching at the apex. Abdomen with six visible sternites, last abdominal segment rounded third segment with thick hair at middle and rest with two setae (Pl.3.B). Female genitalia: Appendage of the 8 th and 9 th abdominal segments (Pl.4) basal gonocoxite 1 flat, broad and glabrous, gonocoxite 2 small and convex with a pointed tip and with three fringes setae, two of them on the outside and the other on the inside. Eight latero-tergite like triangle shaped, membranous and outer margin with row of hairs. Male: descriptions of males are similar to females; with exception: three basal tarsomeres of protarsi much dilated, fifth tarsomeres with rows of ventral setae (Pl.1.B). Male genitalia (Aedeagus): Median lobe with sickle shape, apex twisted and very hooked on dorsal view, left paramere narrowed and right paramere rounded and wide (Pl.5). Diagnostic characters: head and pronotum greenish color in dorsal, yellowish bend at apex of elytra and spot located at interval 3 to 8. This species is determined from the closely species by many features: it differ from C. tetragonoderus Chaudoir, 1876 by having spot connected to apex of elytra; on the other hand, this species differs from C. virgulifer Chaudoir, 1876 and C. pictus Chaudoir, 1856, by the body size, its length is under 13 mm, dorsal color with strong green or greenish glossy color. 42 BULLETIN OF THE IRAQ NATURAL HISTORY MUSEUM Revision of the genus Chlaenius Plate (1): Dorsal view of C. hamifer; (A) Female, (B) Male.

CONCLUSIONS According to the database, references and checklists that related to this group, the genus Chlaenius is one of the most widespread genera in Iraq. Therefore, it is necessary to complete the investigation of its species in the different regions of Iraq, especially the desert areas in the western and southwestern Iraq to update the database of Carabidae. So we expect to add more species to the Iraqi fauna; from the other hand, it is expected that we find that the recorded numbers do not match those actually present in the field, which is may be due to various reasons, including misidentification and others related to the environmental changes, especially in the recent years, which is characterized by the climate of Iraq with a relative rise in temperature and lack of rain. Chlaenius hamifer Chaudoir, 1856 is worldwide distribution, but it was not recorded in the north and south of Iraq. In the previous studies, we find that Ramzi ( 2014) recorded two species in the northern regions that included: C. festivus (Panzer, 1796) and Ch. (Pseudochlaeniellus) lucasii Peyron, 1858, while Al-Ibadi (2021) recorded 3 species: C. festivus (Panzer, 1796), Ch. velutinus (Duftschmid, 1812) and Ch. nigricornis (Fabricius, 1787) and neither of them recorded the species Ch. hamifer Chaudoir, 1856. CONFLICT OF INTEREST STATMENT The results of the present study are part of the requirements of Ph.D. in Insects, Department of Plant Protection, College of Agriculture Engineering Sciences-University of Baghdad for the first author.
