Presence of a species of the genus Eretmocerus (Hymenoptera: Aphelinidae) on Bemisia tabaci (Hemiptera: Aleyrodidae) in the pepper crop from Tucumán, Argentina». The objective of this work was to identify the microhymenopterous parasitoid of B. tabaco in the pepper crop in Lules, Tucumán, Argentina. Sampling consisted in collect ing leaves with whitefly «pupae» with parasitoidism symptoms which were then taken to the Laboratory of Agricultural Zoology, National University of Tucumán (FAZ – UNT), to obtain the adult parasitoids. Semipermanent microscopic preparations were made. Identification keys and taxonomical descriptions from different authors were used. It was identified to Eretmocerus sp., close to E. silvestrii Gerling. The silvestrii group is cited for the first time in South America and in Argentina on B. tabaci in the pepper crop
UNA ESPECIE NUEVA DE ECHEVERIA (CRASSULACEAE) DEL ESTADO
1997
Se describe Echeveria calderoniae como especie nueva para la ciencia, a partir de plantas procedentes de la región noroccidental del estado de Guanajuato, México. Este nuevo taxon se ubica en la serie Secundae (Baker) Berger, diferenciándose de sus componentes conocidos con antelación en sus hojas lanceoladas con el ápice agudo. ABSTRACT Echeveria calderoniae is described as new, a plant native of the northwest of the state of Guanajuato (México). This species belongs to the section Secundae (Baker) Berger, and differs from its known components in its lanceolate and apically acute leaves.
ABSTRACT: It is unusual to find calcareous sponges – Discocoelia – from Late Oligocene sediments, like those offormations Patiecitos and San Luis, as they were supposed have become extinct by the end of the Cretaceous period. Thesponge was found forming sub-decimetric digitations, having been removed, carried and deposited by tropical storms withinexcavated channels along an extended coastal bay. The size of the submarine excavated channels can be deduced from the bulkof their filling: 8 to 10 m in depth and 100-120 m in width, suggestive of hurricane activity not previously evidenced in theCenozoic of Venezuela. The axis of these sediment-filled channels has a NE-SW orientation, similar to that of the currenttrade winds. The presence of storm-generated channels suggests that the paleo-depth of the upper Patiecitos formationdeposits was between 16 and 26 m, a fact confirmed by the associated bivalve fauna. Another finding of sponges -this timesiliceous- was reported from dredges from Cresta de Aves, at depths between 2079 and 1178 m. They are fossil sponges, someof them incrusted with magnesium oxides. They are thought to be from the Late Cenozoic period, when the ridge subsided toits current depth. Only Early Cretaceous sponges had been previously reported from Venezuela. Key words: Porifera, Pharetronids, Oligocene, Tempestites, Venezuela
NUEVA ESPECIE DE HETEROPHRYNUS (AMBLYPYGI: PHRYNIDAE) DEL CARIBE COLOMBIANO
Resumen: Se describe una especie nueva del género Heterophrynus Pocock, 1894, procedente del departamento Sucre, Colom-bia. Se asemeja a la especie amazónica H. batesii (Butler, 1873), pero se diferencia por la forma de los gonópodos de ambos sexos. Esta es la sexta especie del género descrita de este país sudamericano y la primera registrada para su región Caribe. A new species of Heterophrynus (Amblypygi: Phrynidae) from the Colombian Caribe Abstract: A new species of the genus Heterophrynus Pocock, 1894 is described from Sucre department, Colombia. It closely resembles the Amazonian H. batesii (Butler, 1873), from which it differs by having dissimilar female and male gonopods. This is the sixth species of this genus described from this country and also the first one recorded from the Colombian Caribe.
