The activities of erythromycin and clindamycin against 350 Peptostreptococcus strains were studied during a 5-year period (1986 to 1991). In 5.1% of the Peptostreptococcus strains, which presented dissociated resistance (clindamycin MIC, .1 ,ug/ml; erythromycin MIC, >8 Mg/mr), evidence of inducible macrolide-lincosamide resistance was shown. A total of 17.7% of the strains presented a constitutive phenotype; the clindamycin and erythromycin MICs for these strains were greater than 8 Rg/ml.

Se describen dos especies nuevas: Megacraspedus sinevi Vives & Gastón, sp. n. (Gelechiidae) y Sudaniola asselbergsi Vives & Gastón, sp. n. (Pyralidae). Se cita, por primera vez para la fauna de España a Aproaerema ochrofasciella (Toll, 1936), Cochylimorpha erlebachi Huemer & Trematerra, 1997 (Tortricidae) y a Spodoptera frugiperda (Smith, 1797) (Noctuidae). Se describe el macho de Paraswamerdamia kitamurae Gastón & Vives, 2020 (Yponomeutidae) y la hembra de Symmoca mimetica Gozmány, 2008 (Autostichidae). Para la fauna de Sudán, se describe la hembra de Turatia scioneura (Meyrick, 1929) (Autostichidae).
