Abstract A description is provided for Epicoccum purpurascens[Epicoccum nigrum]. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: plurivorous. DISEASE: The species usually occurs as a saprophyte or weak parasite although there are a number of reference to its occurance as a specific parasite. It occurs on a wide range of plants and plant material, human and animal tissue and processed foodstuffs. Generally regarded as a saprophyte or weak parasite but it has been listed as causing leaf spot of cassava (48, 2104), twig blight of Asiatic chestnuts (51, 1193) and because of its reddish-brown pigments (Β-carotene, torularhodin and rhodo-xanthin) it has been referred to as causing 'Red Kernel' disease of sweet corn (54, 2217), Red Blotch of rice (13, 538) and Brown Rot of apple. GEOGRAPHICAL DISTRIBUTION: Although new records of its distribution are constantly being published its range is probably world-wide wherever vegetation occurs. The CMI has material from all the major regions of the world and collections too numerous to list here. TRANSMISSION: Spores of the species are amongst the commonest components of the air spore (51, 1193) and have been frequently isolated from seeds of rice (53, 135), millet (53, 3004) and cereals in general.

Abstract A description is provided for Nectria cinnabarina. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Many species including Ribes and Robinia. This species occurs on conifers and on a wide range of broad-leaved trees and shrubs. DISEASE: Coral spot fungus. Evidence supports the view that this species is a facultative parasite of considerable importance on blackcurrants (48, 3063); it occurs as the cause of cankers of Robinia (54, 1020) and may attack many other woody plants (55, 655). GEOGRAPHICAL DISTRIBUTION: It is very common and widespread in Northern Europe and has frequently been reported from temperate parts of the world, USA, Canada, Australia and New Zealand, and also from India and Hong Kong. TRANSMISSION: Because of the slimy nature of the conidia and the fact that they form a hard crust in dry weather, wind is not considered as important as water in their dispersal. Even the ascospores appear to be extruded or discharged only in moist weather (Jorgensen, 1952). Entry is usually through wounds or dead buds (47, 1181; 48, 3063).

Two new species of Opilioacaridae from Mexico are described, Neocarus chactemalensis sp. nov. and N. comalensis sp. nov., and new records for N. texanus Chamberlin & Mulaik and N. veracruzensis Vazquez & Klompen are presented. Relative positions of internal structures of the ovipositor, a highly variable character, are described based on comparisons of invaginated and evaginated ovipositors. A study of records of Opilioacaridae in Mexico shows that the group is distributed across a wide range of ecosystems and elevations, from dry, semi-desert to wet tropical forest, and coastal plains to the altiplano (>2,000m).

Fifteen species are new records for Tunisian insect fauna: Astata apostata Mercet, 1910; A. gallica de Beaumont, 1942; Dryudella pulawskii Schmid–Egger, 2014; Prosopigastra nuda (Nurse, 1903); P. punctatissima africana de Beaumont, 1955; Tachytes niloticus R. Turner, 1918; Liris agilis (F. Smith, 1856); L. cleopatra de Beaumont, 1961; Miscophus papyrus de Andrade, 1954; Solierella andradei de Beaumont, 1957; S. insidiosa de Beaumont, 1964; Palarus parvulus de Beaumont, 1949; Trypoxylon deceptorium Antropov, 1991; Diodontus insidiosus Spooner 1938; and Mimumesa unicolor (Vander Linden, 1829). Except for Ectemnius confinis (Walker, 1871), all the identified species have new provincial records. Geographical distribution in Tunisia and the world is given. Data published through GBIF (Doi: 10.15470/u8hlo0)

The objective of this work is to further update the records of Argentinean Entomophthoralean fungal species and their geographical distribution. Our survey includes five new records of Zoophthora radicans infecting insect hosts belonging to the orders Diptera, Hemiptera, and Lepidoptera from Pampasic and Littoral regions of Argentina. These new records not only increase the host range of Entomophthoralean fungi but also their geographical distribution around the world.

Abstract A description is provided for Nectria radicicola. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On a very wide range of hosts, Gymnospermae, Monocotyledonae and Dicotyledonae, particularly in temperate regions, especially Fragaria vesca, Narcissus, Vitis vinifera. DISEASE: Root rot, dry brown rot, storage rot or dry rot (37: 3); wilt (32: 261); root plate rot of Narcissus (30: 160); black rot of strawberry (28: 180); black spot of grapes (36: 449). GEOGRAPHICAL DISTRIBUTION: Widespread in Europe. Occurs in N. America, East and South Africa, Australia, New Zealand. TRANSMISSION: By water, rain splash or in soil; infection generally from soil. Contaminated soil is the principal source of infection in nurseries where the fungus is capable of existing for long periods as a saprophyte or as thick-walled chlamydospores (35: 769). Taylor (36: 449) found the fungus only penetrating grapes when the skin was broken.

AbstractEcuador is one of the countries with the highest biodiversity in the world, this can also be seen in the Culicidae family. However, there are a limited number of studies on this group. This work provides a baseline reference for this insect group and information about numerous potential and vector disease species. Species names and records were extracted from the National Mosquito Reference Collection at INSPI-Quito, published literature and web databases. The specimens at the INSPI collection were identified using morphological keys and, in a few cases, using molecular markers in the genus Anopheles. An updated list includes the subfamilies Culicinae and Anophelinae, eight tribes, 22 genera and 200 species. We present 18 species cataloged as new records for Ecuador represented in two subfamilies, 6 tribes and 9 genera. Taxonomic notes, geographical distribution and medical importance data for the species involved are provided. The updated list of Mosquitoes (Diptera: Culicidae) is a guide for researchers and health personnel when studying biodiversity, fauna, insect vectors and strategies to prevent the spread of vector diseases.

Español.  Se dan a conocer nuevas localizaciones y datos corológicos para 98 especies (61 Rhodophyta, 22 Ochrophyta, 15 Chlorophyta) de algas bentónicas marinas recolectadas en el intermareal y submareal de más de 80 localidades de las costas atlánticas y cantábricas de la Península Ibérica. Polysiphonia devoniensis, P. fibrata y Zonaria tournefortii son novedad para Portugal y 5 especies (Bonnemaisonia hamifera, Calosiphonia vermicularis, P. devoniensis, Hincksia intermedia y Derbesia marina stadium Halicystis ovalis) son nuevas citas para Galicia. Paralelamente, se aportan 101 primeras citas provinciales (2 Guipúzcoa, 1 Vizcaya, 8 Cantabria, 5 Asturias, 7 Lugo, 1 A Coruña, 8 Pontevedra, 1 Beira litoral, 15 Estremadura, 20 Alentejo, 25 Algarve y 8 Cádiz) y, además, se dan a conocer 108 segundas citas provinciales. Aunque la flora bentónica marina del Atlántico Peninsular ha sido objeto de numerosos estudios, estos nuevos hallazgos corológicos ponen en evidencia que todavía son necesarios más estudios florísticos en estas costas.English.  In this work, we provide new records and geographical distribution data for 98 seaweeds (61 Rhodophyta, 22 Ochrophyta, 15 Chlorophyta) inhabiting more than 80 sites (intertidal and subtidal) of the Atlantic Iberian Peninsula. Polysiphonia devoniensis, P. fibrata y Zonaria tournefortii are new records for Portugal and 5 species (Bonnemaisonia hamifera, Calosiphonia vermicularis, P. devoniensis, Hincksia intermedia and Derbesia marina stadium Halicystis ovalis) are new records for Galicia. Moreover, 101 new records are reported for the first time in the studied provinces (2 Guipúzcoa, 1 Vizcaya, 8 Cantabria, 5 Asturias, 7 Lugo, 1 A Coruña, 8 Pontevedra, 1 Beira litoral, 15 Estremadura, 20 Alentejo, 25 Algarve y 8 Cádiz) and 108 for the second time. Although the Atlantic marine algae of the Iberian Peninsula are well studied, these new findings show that further floristic studies are necessary to complete our knowledge of the natural heritage of this region.
