Four new species of Aphelinidae (Hymenoptera: Chalcidoidea) from Mexico.

Four new species of Encarsia Förster (Hymenoptera: Aphelinidae) from Mexico are described--E. albata Myartseva sp. n. (State of Nuevo León), E. barracas Myartseva sp. n. (State of Baja California Sur), E. chichenitza Myartseva sp. n. (State of Yucatán) and E. elenae Myartseva sp. n. (State of Tamaulipas). A key to the species of Encarsia in Mexico published in 2012 is modified to include the ne...

Records and descriptions of some Aphelinidae (Hymenoptera: Chalcidoidea) from India

Two new species, Centrodora flemingiae Hayat, sp. nov. and Proaphelinoides assamensis Hayat, sp. nov. (Hymenoptera: Aphelinidae), are described. The latter species is described for an Indian specimen earlier misidentified as P. australis Girault. Also, the following five species are recorded: Coccophagus fumadus Hayat, C. longifasciatus Howard, C. zebratus Howard, Eriaphytis chackoi Subba Rao a...

Analyse en relativité d'échelle du bassin versant du Gardon (Gard, France). Étude de la variation de la dimension fractale en fonction de l'altitude et de l'échelle

Level curves higher than 100 m of the Gardon basin are analysed using scale relativity tools. These curves depend explicitly on scale (box counting method) and altitude. This dependence is solution of a partial derivative equation (in terms of scale and position). Then the descriptions in terms of scale invariance (constant fractal dimension DF ) are generalized to scale covariance (variable DF...
