Hemiptera: Gerromorpha: Gerridae) from Tamil Nadu, India, with a Key to the Species
Zootaxa 3186: 64–68 (2012) ISSN 1175-5326 (print edition) www.mapress.com/zootaxa/ Article ZOOTAXA Copyright © 2012 · Magnolia Press ISSN 1175-5334 (online edition) Lathriobates manohardasi sp. nov. (Hemiptera: Gerromorpha: Gerridae) from Tamil Nadu, India, with a key to the species KAILASH CHANDRA1 & E. EYARIN JEHAMALAR2 Zoological Survey of India, New Alipore, Kolkata- 700 053, India. E-mail: [email protected]; [email protected] Abstract Lathriobates manohardasi sp. nov. is described and compared with known congeners. A key to the species of the genus of world is included. Key words: Trepobatinae, Kannyakumari District, Tamil Nadu, India Introduction Gerridae comprises a group of semi-aquatic bugs that spend almost their entire lives skating above the water sur- face of lentic and lotic environments. Approximately 750 species are distributed among 60 genera and 9 subfami- lies of Gerridae (Moreira, 2011). Thirumalai (2002) reported one species each of Calyptobates, Gnomobates, Lathriobates, and Naboandelus of the subfamily Trepobatinae from India. The world fauna of Lathriobates includes four species: L. obscures Miyamoto, L. rufus Polhemus & Polhemus, L. johorensis Polhemus & Polhemus and L. raja Distant. A fifth species Lathriobates manohardasi sp. nov. is described here. The genus Cryptobates Esaki, 1929 (Gerridae: Heteroptera) is a junior homonym of Cryptobates Fairmaire, 1882 of the family Tenebrionidae (Coleoptera), so the name Lathriobates was proposed as a replacement name by Polhemus (2004), with type species Gerris raja Distant, 1910. Material and methods Study area: Kannyakumari is regarded as the southern most district of Tamil Nadu. The district lies between 77° 15` and 77° 36` E longitude and 8° 03` and 8° 35` N latitude. -

(Hemiptera: Gerromorpha: Veliidae) from Tamil Nadu, India: the first species of the genus described from the Indian subcontinent E. EYARIN JEHAMALAR Zoological Survey of India, New Alipore, Kolkata- 700053, India. E-mail: [email protected] Abstract Strongylovelia lillyae sp. nov. is described from Kanyakumari district, Tamil Nadu, India and constitutes the first species of the genus from Indian subcontinent. The new species is closely related to Strongylovelia setosa Zettel & Tran and S. vasarhelyii Zettel & Tran from Vietnam. A distribution map and photographs of S. lillyae sp. nov. are presented here. Key words: Haloveliinae, taxonomy, Kanyakumari district Introduction Members of the limnic genus Strongylovelia Esaki (1924), are very small tear-shaped water striders, ranging in size between 0.89 mm and 1.80 mm, and belonging to the subfamily Haloveliinae of family Veliidae. The subfamily Haloveliinae contains five known genera, of which, three are marine - Halovelia Bergroth (1893), Xenobates Esaki (1927) and Haloveloides Andersen (1992) - and two are freshwater - Strongylovelia Esaki (1924) and Entomovelia Esaki (1930). The members of Strongylovelia are distributed across the Indomalayan (Sri Lanka, India, southern and southwest China, Vietnam, Thailand, Indonesia, Borneo, Malaysia and Philippines) and Australasian (New Britain and New Guinea) regions. Presently, 27 species and 2 subspecies are recognized, including the new species described here (Esaki, 1924, 1926, Lundblad, 1933, Polhemus, 1979, Lansbury, 1993, Lansbury & Zettel, 1997, Zettel, 2003a,b, Chen et al. -

Ph.D. Thesis, in English. – 85 p., Faculty of Science, University of South Bohemia, České Budějovice, Czech Republic. Annotation Ecology of Veliidae and Mesoveliidae (Hemiptera: Heteroptera: Gerromorpha) was studied in selected European species. The research of these non-gerrid semiaquatic bugs was especially focused on voltinism, overwintering with physiological consequences and wing polymorphism with dispersal pattern. Hypotheses based on data from field surveys were tested by laboratory, mesocosm and field experiments. New data on life history traits and their ecophysiological consequences are discussed in seven original research papers (four papers published in peer-reviewed journals, one paper accepted to publication, one submitted paper and one communication in a conference proceedings), creating core of this thesis. Keywords Insects, semiaquatic bugs, life history, overwintering, voltinism, dispersion, wing polymorphism.

Heteroptera, Gerromorpha, labial tip sensilla, pattern, morphology, function, apomorphic characters Abstract. The present study provides new data on the morphology and distribution of the labial tip sensilla of 41 species of 20 gerro- morphan (sub)families (Heteroptera: Gerromorpha) obtained using a scanning electron microscope. There are eleven morphologically distinct types of sensilla on the tip of the labium: four types of basiconic uniporous sensilla, two types of plate sensilla, one type of peg uniporous sensilla, peg-in-pit sensilla, dome-shaped sensilla, placoid multiporous sensilla and elongated placoid multiporous sub- apical sensilla. Based on their external structure, it is likely that these sensilla are thermo-hygrosensitive, chemosensitive and mechano- chemosensitive. There are three different designs of sensilla in the Gerromorpha: the basic design occurs in Mesoveliidae and Hebridae; the intermediate one is typical of Hydrometridae and Hermatobatidae, and the most specialized design in Macroveliidae, Veliidae and Gerridae. No new synapomorphies for Gerromorpha were identified in terms of the labial tip sensilla, multi-peg structures and shape of the labial tip, but eleven new diagnostic characters are recorded for clades currently recognized in this infraorder. -

Synopsis of the Heteroptera or True Bugs of the Galapagos Islands ' 4k. RICHARD C. JROESCHNE,RD SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 407 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Folklife Studies Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review. -

All the available published and unpublished distributional records of two endangered pond skaters, Gerris asper (Fieber, 1860) and Gerris lateralis Schummel, 1832 (Hemiptera: Heteroptera: Gerridae) in the Czech Republic are summarized and mapped. Gerris asper was originally described from Bohemia by Fieber (1860) without any exact locality and we have been unable to confirm its occurrence with any subsequently collected specimen. The distribution of G. asper in the Czech Republic thus seems to be limited to southern and central Moravia, with a single new record from northern Moravia, where it was found syntopically with G. -
