Species of the Genus Pagasa from Central and South America (Heteroptera: Nabidae) © Zoological Institute, St. Petersburg, 2008 Species of the genus Pagasa from Central and South America (Heteroptera: Nabidae) I.M. Kerzhner & F.V. Konstantinov1 Kerzhner, I.M. & Konstantinov, F.V. 2008. Species of the genus Pagasa from Central and South America (Heteroptera: Nabidae). Zoosystematica Rossica, 17(2): 37-52. A key is given to 22 species of Pagasa found in Central and South America. The following new species are described: P. (Lampropagasa) fl avipennis (Bolivia), P. (Pagasa) henryi (Panama, Peru, Brazil), P. (P.) doesburgi (Surinam), P. (P.) brunneipes (N Brazil), P. (P.) brailovskyi (Mexico, Panama), P. (P.) prostemmatoides (Mexico, Salvador), and P. (P.) margaritae (Surinam). Redescriptions are given for some previously known species. I.M.

  • 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.

Biodiversity Data Journal 9: e62011. https://doi.org/10.3897/BDJ.9.e62011 Abstract Background Dokdo, a group of islands near the East Coast of South Korea, comprises 89 small islands. These volcanic islands were created by an eruption that also led to the formation of the Ulleungdo Islands (located in the East Sea), which are approximately 87.525 km away from Dokdo. Dokdo is important for geopolitical reasons; however, because of certain barriers to investigation, such as weather and time constraints, knowledge of its insect fauna is limited compared to that of Ulleungdo. Until 2017, insect fauna on Dokdo included 10 orders, 74 families, 165 species and 23 undetermined species; subsequently, from 2018 to 2019, we discovered 23 previously unrecorded species and three undetermined species via an insect survey.

  • Pinyon Pine Mortality Alters Communities of Ground-Dwelling Arthropods
    Western North American Naturalist 74(2), © 2014, pp. 162–184 PINYON PINE MORTALITY ALTERS COMMUNITIES OF GROUND-DWELLING ARTHROPODS Robert J. Delph1,2,6, Michael J. Clifford2,3, Neil S. Cobb2, Paulette L. Ford4, and Sandra L. Brantley5 ABSTRACT.—We documented the effect of drought-induced mortality of pinyon pine (Pinus edulis Engelm.) on com- munities of ground-dwelling arthropods. Tree mortality alters microhabitats utilized by ground-dwelling arthropods by increasing solar radiation, dead woody debris, and understory vegetation. Our major objectives were to determine (1) whether there were changes in community composition, species richness, and abundance of ground-dwelling arthro- pods associated with pinyon mortality and (2) whether specific habitat characteristics and microhabitats accounted for these changes. We predicted shifts in community composition and increases in arthropod diversity and abundance due to the presumed increased complexity of microhabitats from both standing dead and fallen dead trees. We found signifi- cant differences in arthropod community composition between high and low pinyon mortality environments, despite no differences in arthropod abundance or richness. Overall, 22% (51 taxa) of the arthropod community were identified as being indicators of either high or low mortality. Our study corroborates other research indicating that arthropods are responsive to even moderate disturbance events leading to changes in the environment. These arthropod responses can be explained in part due to the increase in woody debris and reduced canopy cover created by tree mortality. RESUMEN.—Documentamos el efecto de la mortalidad causada por la sequía del pino piñonero (Pinus edulis Engelm.) sobre comunidades de artrópodos subterráneos. Utilizamos tres variantes en el microhábitat de los artrópodos incrementando la radiación solar, desechos de madera muerta y vegetación baja.

  • A New Record of a Prostemmatine Danrsel Bug Prostemnaa Cardnetis Dohrn (Nabidae: Prostemmatinae from Pakistan and Its Redescri
    INT. J. BIOL. BIOTECH., 3(2): 253-255, 2006. A NEW RECORD OF A PROSTEMMATINE DAMSEL BUG PROSTEMMA CARDUELIS DOHRN (NABIDAE: PROSTEMMATINAE) FROM PAKISTAN AND ITS REDESCRIPTION WITH REFERENCE TO ITS UNKNOWN MALE GENITALIA Imtiaz Ahmad and Hina Afzal Department of Zoology, University of Karachi, Karachi-75270, Pakistan ABSTRACT A prostemmatine damsel bug Prostemma carduelis Dohrn of the family Nabidae is recorded for the first time from Pakistan and is redescribed with reference to its unknown male genitalia. Key Words: Prostemma carduelis, Nabidae, Redescription, Male genitalia. INTRODUCTION Distant (1904 and 1910) treated the damsel bug’s family Nabidae Costa as a subfamily Nabinae Reuter under Reduviidae Latreille including three divisions (tribes) i.e., Pachynomaria Stål (presently treated as an independent family Pachynomidae Stål) and Prostemmaria Reuter (Prostemmatinae Reuter) and Nabidinaria Stål (presently treated as two independent subfamilies Prostemmatinae Reuter and Nabinae Reuter) within the family Nabidae Stål). Stål (1872) and later Reuter and Poppius (1910) although raised damsel bugs to family status but continued to include Pachynomidae Stål under it. Some of the recent authors such as Carayon (1970) and Kerzhner (1981) excluded the Pachynomidae but included the Medocostidae Stys and Velocipedidae Bergroth under Nabidae. Schuh and Stys (1991) and Schuh and Stater (1995) have used the family name Nabidae in the present concept and Kerzhner (1981) classified the subfamily Prostemmatinae into tribes Prostemmatini including the present old-world genus Prostemma Laporte and Phoriticini Stål including Pantropical Phoriticus Stål and Oriental Rhamphocoris Kirkaldy. The present species was earlier known from Sri Lanka and Myanmar and the record from Sialkot in Punjab, Pakistan is certainly a new one.

In total, four genera (Alloeorhynchus Fieber, 1860, Himacerus Wolff, 1811, Nabis Lat- reille, 1802 and Prostemma Laporte, 1832), 22 species and subspecies are listed from Iran. Three of these species are new for the Iranian fauna: Nabis (Nabicula) fl avomarginatus Scholtz, 1847, Nabis (Nabis) rugosus (Linnaeus, 1758) and Prostemma carduelis Dohrn, 1858. Key words. Heteroptera, Nabidae, catalogue, Iran, Palaearctic Region Introduction Damsel bugs (Heteroptera: Nabidae) have a worldwide distribution and include approxi- mately 400 species in about 20 genera (KERZHNER 1981, 1996; KERZHNER & HENRY 2008). All known species are predators of adults and larvae of various stages and groups of insects, e.g., aphids, leafhoppers and lepidopteran eggs and young caterpillars. They may be commonly found on low herbaceous vegetation, shrubs and grasses (LATTIN 1989). They have not been used as biological control agents but are considered benefi cial in natural biological control. The classifi cation of the Nabidae is conjectural.

Arthropods serve this purpose because they are abundant and diverse in urban areas, and relatively easy to collect. Over seven years, in the Central Arizona Phoenix area, arthropod communities in three urban habitat categories were collected and compared to arthropods in natural desert using pitfall traps and non-parametric analyses.

  • Sexual Dimorphism in Winter Survival Rate Differs Little Between Damselbug Species (Heteroptera: Nabidae)
    Eur. J. Entomol. 106: 37–41, 2009 http://www.eje.cz/scripts/viewabstract.php?abstract=1423 ISSN 1210-5759 (print), 1802-8829 (online) Sexual dimorphism in winter survival rate differs little between damselbug species (Heteroptera: Nabidae) STEFFEN ROTH1 and KLAUS REINHARDT2 1Department of Biology, Ecological and Environmental Change Research Group, University of Bergen, Postbox 7800, N-5020 Bergen, Norway; e-mail: [email protected] 2University of Sheffield, Department of Animal and Plant Sciences, Sheffield S10 2TN, UK; e-mail: [email protected] Key words. Winter survival, overwintering, low temperature experiment, sexual dimorphism, Nabidae, Heteroptera, Nabis rugosus, N. ericetorum. N. pseudoferus Abstract. The winter survival of three closely related univoltine heteropterans that overwinter as adults, Nabis rugosus, N. erice- torum and N. pseudoferus was investigated. After 150 days of low temperature treatment (3–5°C, 16L : 8D, r.h. 70–80%) more males than females died. The mortality rate ranged from 88.8 to 93.8% in males and from 54.2 to 60.7% in females. However, these sexual differences in mortality did not differ significantly across the three species and populations of different geographic origin. It remains a general question whether this considerable evolutionary stability in the sex-specific investment into reproduction and sur- vival phylogenetically conserved or frequently evolves anew to similar levels in separated populations and species. In Nabis rugosus, the relative loss of body mass during overwintering was up to 37.8%. This reflects dramatic somatic costs of adult overwin- tering and indirectly supports the hypothesis that food supply during overwintering is important for some heteropteran predators.
