Abstract A new species, Encarsiella tamaulipeca Myartseva and Coronado-Blanco sp. nov., from Mexico is described and illustrated. A new combination is proposed, Encarsiella narroi (Gomez & García) from Encarsia. A key to the species of Encarsiella (females) of the New World is given.

Phylogenetic affinities of Monarea Szépligeti, 1904 (Hymenoptera: Braconidae, Doryctinae, with description of a new species from Mexico

The genus Monarea Szépligeti is recorded from Mexico for the first time. A new species, Monarea fridae sp. nov., is described and illustrated from the states of Morelos, Puebla and Jalisco, Mexico. The phylogenetic placement of the genus is investigated based on nuclear (28S) and mitochondrial (COI) DNA sequence data. Based on the relationships recovered, Monarea is transferred to the tribe Holcobraconini, which is also supported by features of the internal ovipositor structure and the venom glands and reservoir. A key to the four currently recognised species of Monarea is provided.

Taxonomic, host and distribution information for these eight species, and a key to females and males are provided. The male of E. andrewi (Myartseva and Coronado-Blanco) is described from Mexico. Aleurodicus dugesii Cockerell is reported as a new host record for E. andrewi.

Parasitoides del Gusano Barrenador de la Nuez, Acrobasis nuxvorella Neunzig1 en La Comarca Lagunera, México

Resumen. Se identificaron los parasitoides y el grado de parasitismo del gusano barrenador de la nuez (GBN), Acrobasis nuxvorella Neunzig, en huertas de nogal pecanero de la Comarca Lagunera (zona que comprende parte de Coahuila y Durango, México). El parasitismo en huevos varió del 0 al 13% y en larvas del 17.2 al 18.5%. Los parasitoides de huevos del GBN pertenecieron al género Trichogramma. Los parasitoides pertenecen a dos órdenes, seis familias, 12 géneros y 12 especies, parasitando larvas, principalmente, y pupas de A. nuxvorella. Orden Hymenoptera: Apanteles epinotiae Viereck y Macrocentrus instabilis Muesebeck (Braconidae), Goniozus ca nephantidis Muesebeck (Bethylidae), Venturia macilenta nitida Wahl y Eiphosoma vitticolle Cresson (Ichneumonidae), Bugacia sp. (Pteromalidae) y Doliopria sp. (Diapriidae). Orden Diptera: Athrycia sp., Archytas sp., Uclecya sp., Jurinia sp.1 y Jurinia sp.2 (Tachinidae). Los parasitoides de larvas y pupas más abundantes fueron A. epinotiae (24.6%), G. ca nephantidis (14.8%), M. instabilis (11.5%), y Archytas sp. (11.5%). Todas las especies y géneros de parasitoides del GBN encontrados constituyen nuevos registros en México, excepto M. instabilis.

Community Structure of Ichneumonidae (Hymenoptera) in a Mangrove Area in the Coastal Zone of Tamaulipas, Mexico.

espanolSe describe la estructura de las comunidades de Ichneumonidae en un area de manglar y 2 localidades cercanas con diferentes tipos de vegetacion. El area de estudio esta ubicada en los limites de las regiones Neartica y Neotropical en sur del estado de Tamaulipas, Mexico. Las muestras se recolectaron con una trampa Malaise en cada sitio durante 1 ano. La riqueza potencial de especies se determino con el modelo de Clench, los indices de diversidad de Simpson y Shannon-Wiener, asi como las posibles diferencias entre las comunidades con el analisis multivariado de Permanova. Los grados relativos de influencia de las variables espaciales, de tiempo y de distribucion biogeografica en las estructuras comunitarias se determinaron mediante analisis de correspondencia multiple. Los datos mostraron que el area de manglar tiene la mayor riqueza potencial de especies y que hubo diferencias significativas entre las 3 comunidades de ichneumonidos. Las estructuras comunitarias dependen de la distribucion biogeografica de las especies y del mes de recolecta, mientras que las estructuras poco dependientes, del tipo de vegetacion. Tres especies obtenidas en este estudio representan nuevos registros para Mexico y 5 para el estado de Tamaulipas. EnglishThe structure of Ichneumonidae communities in a mangrove area and 2 nearby locations with different vegetation types are described. The study area is located within the limits of the Nearctic and Neotropical regions in the southern part of the state of Tamaulipas, Mexico. Samples were collected with a Malaise trap at each site over a one-year period. We estimated the potential species richness with the Clench model, the Simpson and Shannon-Wiener diversity indexes and the possible differences among communities at different sites using Permanova multivariate analysis. The relative degrees of influence of space, time, and biogeographical distribution on the community structures of ichneumonid wasps were determined using multiple correspondence analyses. Our results showed that the mangrove area had the highest potential species richness, and that there were significant differences among the 3 ichneumonid communities. The community structures depend primarily on the biogeographical distribution of species and secondarily on the month of collection, whereas the type of vegetation contributed with lower variation. Three species obtained in this study are new records for Mexico, and 5 for Tamaulipas.

Abstract A list of parasitoids of the genus Coccophagus Westwood that parasitize the soft scale Parasaissetia nigra (Nietner), in the world, is given. Data on the biology of P. nigra in Mexico are presented. A key to species of Coccophagus associated to P. nigra in Mexico, including possible species of parasitoids, was prepared. A new species, Coccophagus minor Myartseva sp. nov., reared from P. nigra on mistletoe, Phoradendron quadrangulare (Kunth) Griseb., growing over leaves and shoots of huisache, Acacia farnesiana (L.) Willd., in Tamaulipas, Mexico, is described.
