Sœtherl Keywords : Diptera, Chironomidae, systematics, Metriocnemus van der Wulp, keys, new species, type revisions. The congenerity of Arctomyia Lundstrôm, 1915, with Metriocnemus van der Wulp, 1874, is confirmed. Types of Arc- tomyia sibirica Lundstrôm ; Chironomus picipes Meigen, 1818 : Metriocnemus longipalpus Sinharay et Chaudhuri, 1978 ; and Apometriocnemus beringiensis Cranston et Oliver, 1988 ; are examined. Metriocnemus sibiricus is close to M. longipennis (Holmgren), M. picipes is separate from M. atriclava Kieffer, M. longipalpus is a junior synonym of M. picipes,a.nd M. beringiensis is close to M. fuscipes (Meigen).

Ireland, was chosen for the investigation, and from the ecological data available on the immature stages of Eurycnemus (Murray & Ashe 1981) it was assumed for the purposes of the search that E. crassipes is ectoparasitic on Hydropsyche prepupae/pupae. By driving long, upright branches into the Substrate, the riffle area was divided into three rectangular, box- like sections each about 1 m wide and 10 m long, the total area studied being about 30 Square metres. Work began on the downstream end of each box and every stone likely to support Hydropsyche pupal cases was examined. Any such cases found were removed, opened and discarded if nothing was found. Suspect cases were placed in a tray of river water for further examination, and those which contained or were suspected of containing larvae or pupae of E. crassipes were preserved in 75 % alcohol.

    Proceedings of the XV International Symposium on Chironomidae, pp. 285-293 Edited by Leonard C. Ferrington Jr. (2010) Phytotelmatocladius, A New Genus from Bromeliads in Florida and Brazil (Diptera: Chironomidae: Orthocladiinae) J. H. EPLER 461 Tiger Hammock Road, Crawfordville, Florida 32327, U.S.A. ABSTRACT: Phytotelmatocladius delarosai, new genus, new species, is described from bromeliad phytotelmata in southern Florida and Brazil. The larva had previously been keyed and diagnosed as Metriocnemus sp. B in Epler (1992, 1995) and Orthocladiinae genus H in Epler (2001). The pupa lacks a thoracic horn and pedes spurii A and B, has tergites II-VII and anal lobe mostly covered with shagreen spines, with well developed spinules on the conjunctiva between most tergites and sternites, and has only two macrosetae on each of its truncated anal lobes. The female has bare eyes, scalpellate acrostichals, only one or no seta on the squama, no setae on wing membrane, a long comb of 40+ sensilla chaetica on the mid leg basitarsus and seminal capsules without microtrichia. This new genus shows similarities to Compterosmittia, Limnophyes, Paralimnophyes and Thienemannia. Only female adults and pupae have been collected or reared (excepting larvae which can not be sexed), leading one to assume that this taxon may be parthenogenetic. INTRODUCTION Phytotelmata are the small bodies of water impounded by plants, such as bromeliads or pitcher plants. Phytotelmata often contain a variety of invertebrate and vertebrate life forms, among them Chironomidae (Cranston & Kitching, 1995; Epler and Janetzky, 1999; Frank and Fish, 2008; Picado, 1913 and others). In 1980 I made some collections from arboreal Tillandsia (a bromeliad genus native in Florida) phytotelmata that contained two taxa of orthocladine larvae.

Ltd., 1-11-1, Umehara, Hatsukaichi-shi, Hiroshima 739-0494, Japan Abstract Ecological studies were conducted on marine chironomids in south-western Japan. A total of 20 species was collected. For vertical distribution, only a few species was distributed only at high or middle intertidal zone while many species were distributed only at low zone. For substrate preference, some species were collected only on rocks or in mud while many species were collected only in seaweeds. For geographical distribution, a few species was collected only in the southwestern islands or in the oceanic coast in the Japanese main islands. In contrast, some species were collected in the Seto Inland Sea and the oceanic coast in the main islands, in the oceanic coast in the main islands and the southwestern islands, or in all areas. For seasonal emergence, Dicrotendipes enteromorphae was collected only in summer and autumn, and Semiocladius endocladiae was collected in all seasons. Other species were collected only in autumn and winter, or only in winter and spring. These results suggest that many chironomid species with a variety of lifestyles dwell in intertidal zones and have some important roles in the ecosystems. Key Words: sessile organisms, chironomid, distribution, intertidal zone, seaweed INTRODUCTION Chironomids (Diptera: Chironomidae) are one of the widely distributed insects on the earth (Nihon yusurika kenkyu-kai, 2010).

The information contained herein may not be cited or reproduced without permission of the author or the S.U.N.Y. Oneonta Biology Department ABSTRACT The species of Chironomidae inhabiting Otsego Lake, New York, were studied from 1979 through 1982. This report presents the results of a variety of collecting methods used in a diversity of habitats over a considerable temporal period. The principle emphasis was on sound taxonomy and rearing to associate immatures and adults. Over 4,000 individual rearings have provided the basis for description of general morphological stages that occur during the life cycles of these species. Keys to the larvae and pupae of the 4 subfamilies and 10 tribes of Chironomidae collected in Otsego Lake were compiled. Keys are also presented for the immature stages of 12 Tanypodinae and 2 Diamesinae species found in Otsego Lake. Labeled line drawings of the majority of structures and measurements used to identify the immature stages of most species of chironomids were adapted from the literature. Extensive photomicrographs are presented along with larval and pupal characteristics, taxonomic notes, synonymies, recent literature accounts and collection records for 17 species. These include: Chironominae­ Paratendipes albimanus (Meigen) (Chironomini); Ortl10cladiinae ­ Psectrocladius (Psectrocladius) simulans (Johannsen) and I!ydrobaenus johannseni (Sublette); Diamesinae - Protanypus ramosus Saether (Protanypodini) and Potthastia longimana Kieffer (Diamesini); and Tanypodinae - Clinotanypus (Clinotanypus) pinguis (Loew) (Coelotanypodini), Tanypu~ (Tanypus) punctipennis Meigen (Tanypodini), Procladius (Psilotanypus) bellus (Loew); Var.

Key words: Diptera, Chironomidae, Orthocladiinae Introduction Corynoneura Winnertz (1984) is a special genus characterized by small size (less than 3.00mm) and a thick clavus terminating at or before the midpoint of the wing. This genus is world-wide in distribution, but it was frequently overlooked because of their small size. Fu, Sæther & Wang (2009) provided a key to the sufficiently known males in the world, and gave a preliminary estimate of the phylogenetic relationships of the known males. Subsequently, Wiedenbrug et al. revised the genus Corynoneura from Neotropical region (Wiedenbrug & Trivinho-Strixino 2011, Wiedenbrug et al 2012) , Makarchenko & Makarchenko (2010) and Krasheninnikov (2012) described 7 new species from Russia.

E-mail: [email protected] Abstract The chironomid diversity of Central America is virtually underestimated and there is almost no knowledge on the chirono- mid remains accumulated in surface sediments of lakes. Thus, in the present study we provide information on the larval sub-fossil chironomid fauna from surface sediments in Central American lakes for the first time. Samples from 27 lakes analysed from Guatemala, El Salvador and Honduras yielded a total of 1,109 remains of four subfamilies. Fifty genera have been identified, containing at least 85 morphospecies. With 45 taxa, Chironominae were the most specious and also most abundant subfamily. Tanypodinae with 14 taxa dominated in about one third of the sites. Orthocladiinae were pre- sented by 24 taxa, but were recorded in 9 sites, being dominant in only one site.

FLIES of the family CHIRONOMIDA.E may be distinguished from other Nematocerous families of Diptera by the following combination of charac­ ters : Ocelli absent ; antennae hairy (especially in d') ; six to eight veins reaching wing-margin; one or both anal veins not reaching margin; vein M simple; cross-veins R-M and M-CU (latter when present) near middle of wing. The reduced mouthparts and the fact that the costa is not con­ tinued around the entire wing provide simple distinctions from CuLICIDAE, to which family some groups bear a superficial resemblance. The closely­ related CERA.TOPOGONIDA.E (" biting midges ") were formerly included in the CHIRONOMIDA.E (" non-biting midges"), and differ most obviously by the forked vein M ; head rounded behind instead of flattened ; postnotum without a distinct median longitudinal furrow or keel, which is present in most CHIRONOMIDA.E .
