Nabidae of the West Indies (Heteroptera) © Zoological Institute, St. Petersburg, 2007 Nabidae of the West Indies (Heteroptera) I.M. Kerzhner Kerzhner, I.M. 2007. Nabidae of the West Indies (Heteroptera). Zoosystematica Rossica, 16(2): 225-234. Eighteen species of Nabidae are recorded from the West Indies. Alloeorhynchus slateri sp. n. (Jamaica), A. jamaicensis sp. n. (Jamaica), A. maldonadoi sp. n. (Puerto Rico) and Pagasa cobbeni sp. n. (Curaçao) are described. Arachnocoris karukerae Lopez, 1990 is placed in synonymy with A. berytoides (Uhler, 1894). I.M.

Received: 2011.09.17; Accepted: 2011.11.10; Published: 2011.11.24 Abstract The complete sequence of the mitochondrial DNA (mtDNA) of the damsel bug, Al- loeorhynchus bakeri, has been completed and annotated in this study. It represents the first sequenced mitochondrial genome of heteropteran family Nabidae. The circular genome is 15, 851 bp in length with an A+T content of 73.5%, contains the typical 37 genes that are arranged in the same order as that of the putative ancestor of hexapods. Nucleotide composition and codon usage are similar to other known heteropteran mitochondrial genomes.

  • A Comparison of the External Morphology and Functions of Labial Tip Sensilla in Semiaquatic Bugs (Hemiptera: Heteroptera: Gerromorpha)
    Eur. J. Entomol. 111(2): 275–297, 2014 doi: 10.14411/eje.2014.033 ISSN 1210-5759 (print), 1802-8829 (online) A comparison of the external morphology and functions of labial tip sensilla in semiaquatic bugs (Hemiptera: Heteroptera: Gerromorpha) 1 2 JOLANTA BROŻeK and HERBERT ZeTTeL 1 Department of Zoology, Faculty of Biology and environmental Protection, University of Silesia, Bankowa 9, PL 40-007 Katowice, Poland; e-mail: [email protected] 2 Natural History Museum, entomological Department, Burgring 7, 1010 Vienna, Austria; e-mail: [email protected] Key words. 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.

  • Review of the West Indian Arachnocoris Scott, 1881 (Hemiptera: Nabidae), with Descriptions of Two New Species, and a Catalog of the Species1
    Life: The Excitement of Biology 4(1) 32 Review of the West Indian Arachnocoris Scott, 1881 (Hemiptera: Nabidae), with Descriptions of Two New Species, and a Catalog of the Species1 Javier E. Mercado2, Jorge A. Santiago-Blay3, and Michael D. Webb4 Abstract: We review the West Indian species of Arachnocoris, a genus of spider-web dwelling kleptoparasitic nabids. We recognize five species: A. berytoides Uhler from Grenada, A. darlingtoni n. sp. from Hispaniola, A. karukerae Lopez-Moncet from Guadeloupe, A. portoricensis n. sp. from Puerto Rico, and A. trinitatis Bergroth from Trinidad. West Indian Arachnocoris antennal and profemoral color banding patterns are useful diagnostic characters and may have evolved to mimic their spider hosts, which are often island endemic spiders in the family Pholcidae. We provide a simplified and illustrated key to the species based on external characters. A catalog for the 16 recognized species of Arachnocoris is presented. Keywords: Hemiptera, Nabidae, Arachnocoris, new species, Neotropical, West Indies Introduction The Nabidae are a relatively small family in the insect order Hemiptera with approximately 20-30 genera and 400-500 described species (Henry 2009, Faúndez and Carvajal 2014). All described species are terrestrial predators. Some species are considered beneficial to humans as these help control populations of agricultural pests. Several species of Nabis have been reported as biting humans (Faúndez 2015). Within the Nabidae Arachnocoris is one of two genera in the tribe Arachnocorini. The arachnophilic genus5 Arachnocoris Scott is a small and little-known group of specialized kleptoparasitic nabids that spend their life- stages living in a relatively treacherous habitat, namely a spider’s web, particularly non-sticky portions of it (Henry 1999; Mercado-Santiago-Blay 2015; Figure 1, this paper).

Keywords: Hemiptera, Nabidae, Arachnocoris, new species, Neotropical, West Indies Introduction The Nabidae are a relatively small family in the insect order Hemiptera with approximately 20-30 genera and 400-500 described species (Henry 2009, Faúndez and Carvajal 2014). All described species are terrestrial predators. Some species are considered beneficial to humans as these help control populations of agricultural pests. Several species of Nabis have been reported as biting humans (Faúndez 2015). Within the Nabidae Arachnocoris is one of two genera in the tribe Arachnocorini. The arachnophilic genus5 Arachnocoris Scott is a small and little-known group of specialized kleptoparasitic nabids that spend their life- stages living in a relatively treacherous habitat, namely a spider’s web, particularly non-sticky portions of it (Henry 1999; Mercado-Santiago-Blay 2015; Figure 1, this paper).

  • RECORDS of the HAWAII BIOLOGICAL SURVEY for 1998 Part 1: Articles
    1 RECORDS OF THE HAWAII BIOLOGICAL SURVEY FOR 1998 Part 1: Articles Editors’ Preface We are pleased to present the fifth annual compilation of Records of the Hawaii Biological Survey. The number and diversity of taxa reported in these issues attest to the value of the Records as part of the ongoing effort to inventory the Hawaiian biota. The Hawaii Biological Survey, established by the Hawaii State Legislature in 1992 as a program of the Bishop Museum, is an ongoing natural history inventory of the Hawaiian Archipelago. It was created to locate, identify, and evaluate all native and non- native species of flora and fauna within the state; and by State Law to maintain the refer- ence collections of that flora and fauna for a wide range of uses. In coordination with related activities in other federal, state, and private agencies, the Hawaii Biological Sur- vey gathers, analyzes, and disseminates biological information necessary for the wise stewardship of Hawai‘i’s biological resources Some of the highlights of Records of the Hawaii Biological Survey for 1998 include: • an update of numbers of species in Hawai‘i; • a checklist of the Hymenoptera of Midway Atoll; • a list of the terrestrial isopods from Midway Atoll; • results of an extensive survey of apple snails from watercourses on O‘ahu; • new records of plants, insects, and other invertebrates resulting from field surveys and continued curation of Hawaiian collections at Bishop Museum and else- where An intensive and coordinated effort has been made by the Hawaii Biological Survey to make our products, including many of the databases supporting papers published here, available to the widest user-community possible through our web server.

  • A Faunistic Approach to Assess Potential Side-Effects of Genetically Modified Bt-Corn on Non-Target Arthropods Under Field Conditions
    Biocontrol Science and Technology (March 2004), Vol. 14, No. 2, 129Á/170 A Faunistic Approach to Assess Potential Side-Effects of Genetically Modified Bt-Corn on Non-Target Arthropods Under Field Conditions 1 2 1 1 M. P. CANDOLFI ,K.BROWN, C. GRIMM , B. REBER AND H. SCHMIDLI1 1Syngenta Crop Protection AG, CH-4002 Basel, Switzerland; 2Ecotox Limited, Tavistock, Devon, UK (Received 31 October 2001; accepted 13 May 2003) A faunistic study investigating the potential side-effects of corn (Zea mays) genetically modified to express a truncated Cry1Ab protein derived from Bacillus thuringiensis subsp. kurstaki, on non-target arthropods was carried out under field conditions. The communities of non-target arthropods in the soil, on the leaves and flying in the crop area were monitored throughout the growing season. Water-treated, untransformed corn served as a control, and a spray application of a bacterial Bt insecticide (Delfin WG) and a synthetic insecticide (Karate Xpress) used to control the European corn borer (Ostrinia nubilalis; Lepidoptera: Pyralidae) acted as positive reference treatments. Results were analyzed using a principal response curve. Significantly lower infestations by the lepidopteran target species O. nubilalis were observed in the Bt-corn plots compared to the control. No effects of Bt-corn on the communities of soil dwelling and non-target plant dwelling arthropods were observed. A trend towards a community effect on flying arthropods was observed with lower abundance of adult Lepidoptera, flies in the families Lonchopteridae, Mycetophilidae and Syrphidae, and the hymenopteran parasitoids Ceraphronidae. Effects were weak and restricted to two sampling dates corresponding to anthesis.
