  • Spiders of the Hawaiian Islands: Catalog and Bibliography1
    Pacific Insects 6 (4) : 665-687 December 30, 1964 SPIDERS OF THE HAWAIIAN ISLANDS: CATALOG AND BIBLIOGRAPHY1 By Theodore W. Suman BISHOP MUSEUM, HONOLULU, HAWAII Abstract: This paper contains a systematic list of species, and the literature references, of the spiders occurring in the Hawaiian Islands. The species total 149 of which 17 are record­ ed here for the first time. This paper lists the records and literature of the spiders in the Hawaiian Islands. The islands included are Kure, Midway, Laysan, French Frigate Shoal, Kauai, Oahu, Molokai, Lanai, Maui and Hawaii. The only major work dealing with the spiders in the Hawaiian Is. was published 60 years ago in " Fauna Hawaiiensis " by Simon (1900 & 1904). All of the endemic spiders known today, except Pseudanapis aloha Forster, are described in that work which also in­ cludes a listing of several introduced species. The spider collection available to Simon re­ presented only a small part of the entire Hawaiian fauna. In all probability, the endemic species are only partly known. Since the appearance of Simon's work, there have been many new records and lists of introduced spiders. The known Hawaiian spider fauna now totals 149 species and 4 subspecies belonging to 21 families and 66 genera. Of this total, 82 species (5596) are believed to be endemic and belong to 10 families and 27 genera including 7 endemic genera. The introduced spe­ cies total 65 (44^). Two unidentified species placed in indigenous genera comprise the remaining \%. Seventeen species are recorded here for the first time. In the catalog section of this paper, families, genera and species are listed alphabetical­ ly for convenience.

Cortaga, Maria Luz J. Sison, Joseph P. Lagman, Edward Cedrick J. Fernandez and Hayde F. Galvez Institute of Plant Breeding, College of Agriculture and Food Science, University of the Philippines Los Baños, College, Laguna, Philippines 4031 Corresponding author: [email protected] (Received: October 3, 2018; Accepted: May 19, 2019) ABSTRACT The devastation of millions of coconut palms caused by outbreak infestation of the invasive Coconut Scale Insect (CSI) Aspidiotus rigidus Reyne, has posed a serious threat to the industry in the Philippines. The life history of A. rigidus on coconut and mangosteen was comparatively studied to understand the effects of host-plant species on its development, to investigate potential host-suitability factors that contributed to its outbreak infestation, and to gather baseline information on the development and characteristics of this pest. The study was conducted at the Institute of Plant Breeding, College of Agriculture and Food Science, University of the Philippines Los Baños. Insect size (body and scale) was not significantly different on both hosts during egg, crawler, white cap, pre-second and second instar stages, as well as during male pre-pupal, pupal and adult stages. The female third instars and adults, however, were bigger on mangosteen than on coconut. At the end of second instar, sexual differentiation was very visible wherein parthenogenic females further undergone two developmental stages: third instar and adults that feed permanently on the leaves. Males undergone three stages: pre- pupa, pupa and winged adults.

  • Mollusca, Neogastropoda) from the Mozambique Channel and New Caledonia
    Bull. Mus. natn. Hist, nat., Paris, 4e ser., 3, 1981, section A, n° 4 : 985-1009. On a collection of buccinacean and mitracean Gastropods (Mollusca, Neogastropoda) from the Mozambique Channel and New Caledonia by W. 0. CERNOHORSKY Abstract. — The present paper deals with a collection of 59 species of buccinacean and mitra- cean gastropods belonging to 4 families from moderately shallow to deep water around the Mozam- bique Channel area, north of Madagascar. A total of 27 % of the species recovered are new geogra- phical range extensions. The New Caledonian material consists of 21 species belonging to 5 fami- lies, and was dredged, with one exception, in moderately deep water. A total of 38 % of the New Caledonian species represent new geographical records, and one of these is a new species : Voluto- mitra (Waimatea) vaubani n. sp. The new name Vexillum (Costellaria) duplex is proposed for the homonymous Mitra simphcissima Schepman, 1911, and its var. glabra Schepman, 1911. Résumé. — L'auteur étudie une collection de 59 espèces appartenant à 4 familles de Gasté- ropodes Buccinacea et Mitracea dragués dans le nord du canal du Mozambique, à des profondeurs diverses. L'étude montre une extension de l'aire de répartition connue pour 27 % des espèces. Le matériel néo-calédonien comprend 21 espèces appartenant à 5 familles et a été dragué, à une exception près, en eau relativement peu profonde. L'aire de répartition connue se trouve étendue pour 38 % des espèces, dont une est nouvelle : Volulomilra (Waimatea) vaubani n. sp.

  • Predator Defense Mechanisms in Shallow Water Sea Cucumbers (Holothuroidea)
    PREDATOR DEFENSE MECHANISMS IN SHALLOW WATER SEA CUCUMBERS (HOLOTHUROIDEA) JESSICA A. CASTILLO Environmental Science Policy and Management, University of California, Berkeley, California 94720 USA Abstract. The various predator defense mechanisms possessed by shallow water sea cucumbers were surveyed in twelve different species and morphs. While many defense mechanisms such as the presence of Cuverian tubules, toxic secretions, and unpalatability have been identified in holothurians, I hypothesized that the possession of these traits as well as the degree to which they are utilized varies from species to species. The observed defense mechanisms were compared against a previously-derived phylogeny of the sea cucumbers of Moorea. Furthermore, I hypothesized that while the presence of such structures is most likely a result of the species’ placement on a phylogenetic tree, the degree to which they utilize such structures and their physical behavior are influenced by their individual ecologies. The presence of a red liquid secretion was restricted to individuals of the genus Holothuria (Linnaeus 1767) however not all members of the genus exhibited this trait. With the exception of H. leucospilota, which possessed both Cuverian tubules and a red secretion, Cuverian tubules were observed in members of the genus Bohadschia (Ostergren 1896). In accordance with the hypothesis, both the phylogenetics and individual ecology appear to influence predator defense mechanisms. However, even closely related species of similar ecology may differ considerably. Key words: holothurians; defense; toxicity; Cuverian tubules; Moorea, French Polynesia INTRODUCTION (Sakthivel et. Al, 1994). Approximately 20 species in two families and five genera, Sea cucumbers belong to the phylum including Holothuria, Bohadschia, and Thenelota, Echinodermata and the class Holothuroidea.
