查看更多>>摘要：The adult females of three new scale insect species are described from Fiji: Crystallotesta marika Hodgson & Lagowska (Coccidae: Cardiococcinae); Paracoccus boumaensis Hodgson & Lagowska (Pseudococcidae) and Pseudaulacaspis pyr-rosiae Hodgson & Lagowska (Diaspididae). The genus Crystallotesta had previously only been known from New Zealand. P. pyrrosiae is the third possibly endemic species of Pseudaulacaspis to be described from Fiji. In addition, leery a imperatae Rao (Monophlebidae), Bambusaspis bambusae (Boisduval) and B. robusta (Green) (Asterolecaniidae), Kilifia acuminata (Signoret) and Milviscutulus ciliatus Williams & Watson (Coccidae), and Maconellicoccus hirsutus (Green), Nipaecoccus nipae (Maskell) and Phenacoccus parvus Morrison (Pseudococcidae) are recorded from Fiji for the first time. The adult female of I, imperatae is redescribed. It is considered that M. hirsutus and N. nipae could be potentially very important ecologically and economically. A complete checklist of Coccoidea known from Fiji, along with their known island distributions and host plants, is appended. We also record Pseudaulacaspis coluisuvae Williams & Watson from the Solomon Islands for the first time.

Mimastra oblonga group comprises 7 valid species: M. oblonga (Gyllenhal, 1808) comb, nov.; M. cyanura (Hope, 1831); M. lunata (Kollar & Redtenbacher, 1844); M soreli Baly, 1878; M. latimana AUard, 1889; M. guerryi Laboissiere, 1929 and M. anicka sp. nov. (Thailand and Myanmar); while M. tarsalis group includes only one species—M. tarsalis Medvedev, 2009. The primary types of almost all relevant taxa were examined. Galleruca oblonga Gyllenhal, 1808, listed for many years in the genus Aulacophora, is transferred to Mimastra. Status restored for four species (M lunata, M. soreli, M. latimana and M. guerryi), often listed as synonyms of M. cyanura. Mimastra apicalis Baly, 1886 is a new junior synonym of M lunata {Mimastra apicalis Baly syn. nov.) and M quadrivittata Mader, 1938 is confirmed as a synonym of M. guerryi. Lectotypes are designated for Galleruca oblonga, Mimastra cyanura, M. lunata, M. apicalis and M. soreli. The syntype series of M. soreli consists of a mixture of two species. Its identity is fixed for the species from Sichuan. The second part of the syntype series refersto M. oblonga. Male protarsus, protibia and male and female genitalia of all the species are illustrated and key to the species is given.
查看更多>>摘要：An update to the catalogue of the Cydnidae (Hemiptera) of the Westem Hemisphere (Froeschner 1960) is given. A total of 6 genera and 21 species are listed together with their synonyms. References are given for the original descriptions and the subsequent taxonomic position, the location of types, and the geographic distribution. A comprehensive bibliography is provided. Cydnids, known popularly as "burrower bugs", are usually black or brown, small to medium in size (2 to 20 mm), and live deep in the soil where they are root-feeders (Schaefer, 1988). Some are considered important pests of agricultural crops such as com, potato, onion, sorghum, pastures, with as high as 100% loss in soybean crops having been recorded. Cydnidae show varying degrees of matemal care of eggs and early instars (Filippi-Sukamoto et al., 1995; Kight, 1995, 1996, 1997; Tachikawa et al., 1985).
查看更多>>摘要：One new species of flower bug, Scoloposcelis koreanus Jung & Yamada, sp. nov., that inhabits shiitake mushroom farms, is described from Gangwon-do Province, South Korea. Diagnosis, description and biological notes of the new species are presented, along with a key to the species of Scolopocelis from the Palaearctic Region. Scoloposcelis Fieber, 1864 is a small genus in the tribe Scolopini (Hemiptera: Heteroptera: Anthocoridae). As other flower bugs that prey on small arthropods, their predaceous habits of Scoloposcelis have attracted the attention of researchers who work in forest-ecosystems (Lattin 1999), especially as the predators of bark beetles and other tiny arthropods that occur under or between the barks of conifers or deciduous trees (cf.,Carayon 1954a, 1956; Mura-leedharan & Ananthakrishnan 1974; Pericart 1996; Yamada & Hirowatari 2005). The genus is characterized by the body being elongated, flattened, and parallel-sided, the femur usually spinulate on the ventral surface, and the ura-denia having an ampulla, a unique glandular opening on the male abdominal sternum IV (Carayon 1954b).
