Se entrega para los coleópteros acuáticos, una reseña acerca de la diversidad y riqueza de familias, géneros y especies de los subórdenes Hydradephaga y Polyphaga, presentes en Chile. Hydradephaga está representado por las familias Dytiscidae, Gyrinidae y Haliplidae. Polyphaga por Hydrophilidae, Hydraenidae, Elmidae y Psephenidae. A excepción de Lancetes, que es el género más diversificado con 14 especies, la mayoría de los taxa de ambos subórdenes son monoespecíficos. En relación a aspectos biogeográficos, Chile no presenta familias endémicas. Sin embargo, se han descrito situaciones de endemismo de algunas especies para el Archipiélago de Juan Fernández (Lancetes backstroni, Anisomeria bistriata), e Isla de Pascua (Bidessus skottsbergi). En el continente... |

The dynamics of Enochrus variegatus (Steinheil) and Enochrus vulgaris (Steinheil) in temporary pools and permanent ponds were studied in an urban park of Buenos Aires, Argentina. Samples were collected from both types of habitats weekly throughout one year, and variables like water surface and vegetation cover were recorded. In permanent ponds, adults of both species were found throughout the study period, while in temporary pools their presence depended on the availability of water. Differences in their reproductive seasons and breeding sites were observed. Enochrus vulgaris was characterized by an opportunistic strategy, and its larvae were detected in both types of habitats, associated mainly with spring and summer temperatures. Conversely, E.... |
