Evidence of Establishment of Bagous Hydrillae (Coleoptera

South Campus Drive, University of Arizona, Tucson, Arizona 85721, USA *Corresponding author: E-mail: [email protected] ABSTRACT The semi-aquatic weevil Bagous hydrillae was released during 1991-1996 at 19 sites in 4 states in attempts to control the aquatic weed hydrilla, Hydrilla verticillata. Fourteen of the sites were in Florida, 2 each in Texas and Georgia and one site in Alabama. Over 320,000 adult weevils were included in these releases. Despite the fact that a few adults were recovered as late as 4.5 yr post-release, presence of permanent, self-perpetuating populations was never confirmed. Then, during 2009 adult B. hydrillae were collected in southern Louisiana, at least 580 km from the nearest release site and 13 yr after attempts to establish this insect had ter- minated. This suggests that earlier recoveries were indicative of successful establishment and that this weevil species has persisted and dispersed widely in the southeastern USA. -

Hydraenidae of Djibouti, with Description of Two New Species (Coleoptera: Hydraenidae)
50 Koleopt. Rdsch. 87 (2017) Koleopterologische Rundschau 87 51–84 Wien, September 2017 Hydraenidae of Djibouti, with description of two new species (Coleoptera: Hydraenidae) M.A. JÄCH & J.A. DELGADO Abstract The family Hydraenidae (Coleoptera) is recorded from Djibouti (East Africa) for the first time. Two new species are described: Limnebius (Bilimneus) josianae, and Ochthebius (s.str.) loulae (O. atriceps group). Three species are recorded from the African Continent for the first time: Hydraena (Hydraen- opsis) arabica BALFOUR-BROWNE, 1951, Limnebius (Bilimneus) arabicus BALFOUR-BROWNE, 1951, and Ochthebius (s.str.) micans BALFOUR-BROWNE, 1951 (O. punctatus group). One species, Hydraena (Hydraenopsis) quadricollis WOLLASTON, 1864, is recorded from Djibouti for the first time. One species of the Ochthebius marinus group, strongly resembling O. chappuisi ORCHYMONT, 1948, described after four females from southern Ethiopia (Omo River) and northern Kenya (Lake Turkana), could not be identified with certainty. Habitus photographs and line drawings of the genitalia of all seven species known from Djibouti (except Limnebius arabicus) are provided. In addition, the male genitalia of two other species of Ochthebius LEACH, 1815 are also illustrated. Keys to the species of the three genera of Hydraenidae from Djibouti are also provided. Key words: Coleoptera, Hydraenidae, Hydraena, Limnebius, Ochthebius, taxonomy, new species, Djibouti, East Africa. Introduction So far, no Hydraenidae have ever been recorded from Djibouti. During an expedition to Djibouti, organized by the Association Djibouti Nature (www.djiboutinature.org), numerous water beetles were collected by the senior author and M. Madl in January/February 2016. During this expe- dition a total of seven species of Hydraenidae, including two new species, has been collected. -

Twenty-seven species are found in the Paleocene, 442 in the Eocene and 94 in the Oligocene. The greatest diversity of Curculionoidea is described from the Eocene of Europe and North America. The richest faunas are known from Eocene localities, Florissant (177 species), Baltic amber (124 species) and Green River formation (75 species). The family Curculionidae dominates in all Paleogene localities. Weevil species associated with herbaceous vegetation are present in most localities since the middle Paleocene. A list of Curculionoidea species and their distribution by location is presented. Keywords: Coleoptera; Curculionoidea; fossil weevil; faunal structure; Paleocene; Eocene; Oligocene 1. Introduction Research into the biodiversity of the past is very important for understanding the development of life on our planet. Insects are one of the Main components of both extinct and recent ecosystems. Coleoptera occupied a special place in the terrestrial animal biotas of the Mesozoic and Cenozoics, as they are characterized by not only great diversity but also by their ecological specialization. -

Measurements of younger larval instars are also given. The biology of the species is discussed in association with larval morphology and feeding habits. Overall larval and pupal morphological characters of the genus Bagous are presented. Confirmation of the larva identification as Bagous claudicans species was conducted by cytochrome oxidase I (COI) sequencing. DNA barcoding was useful for specimen identification of larval stages. The systematic position of the species within the Bagous collignensis-group, based on morphological and molecular results, is also discussed. Keywords: Weevils; Coleoptera; Curculionidae; Bagoini; Bagous; taxonomy; morphology; larva; pupa; biology; COI; DNA barcoding 1. Introduction The globally distributed (except for Central and South America) weevil genus Bagous Germar, 1817 includes about 300 valid species, of which approximately 130 occur in the Palaearctic region, 82 in the Western Palaearctic, and 31 in Central Europe [1–7]. -
