          Abstract

          The genus Quadriops Hansen, 1999 is revised and redescribed. The genus is found to contain six species, including two that are here described as new: Quadriops clusia sp. n. (Brazil, Guyana, Suriname) and Q. acroreius sp. n. (Suriname, French Guiana). Two species are found to be junior subjective synonyms of Q. depressus Hansen, 1999: Q. amazonensis García, 2000, syn. n. and Q. politus Hansen, 1999, syn. n. The male of Q. similaris Hansen, 1999 is described for the first time. New records are provided for Q. dentatus Hansen, 1999, Q. reticulatus Hansen, 1999, and Q. similaris . All species are described and illustrated in detail. Most species are confirmed as having a terrestrial way of life, with several species being found in rotten fruits, sap flows, and dead wood. Furthermore, we discuss ecological trends of the species given their collecting information.

          Resumen

          El género Quadriops Hansen, 1999 es revisado y redescrito. El género contiene seis especies, incluyendo dos que se describen aquí como nuevas: Quadriops clusia sp. n. (Brasil, Guyana, Surinam) y Q. acroreius sp. n. (Surinam, Guyana Francesa). Dos especies se sinonimizan con Q. depressus Hansen, 1999: Q. amazonensis García, 2000, syn. n. y Q. politus Hansen, 1999, syn. n. El macho de Q. similaris Hansen, 1999 se describe por primera vez. Se proveen nuevos registros para Q. dentatus Hansen, 1999, Q. reticulatus Hansen, 1999, y Q. similaris . Todas las especies son descritas e ilustradas en detalle. La mayoría de las especies presentan un modo de vida terrestre, con varias especies encontradas en frutos podridos, flujos de savia y madera muerta. Además, se discuten tendencias ecológicas de las especies dada su información de colecta.

            Australian Beetles Volume 1

            This three-volume series represents a comprehensive treatment of the beetles of Australia, a relatively under-studied fauna that includes many unusual and unique lineages found nowhere else on Earth. Volume 1 contains keys to all 117 beetle families found in Australia, and includes over 1100 illustrations of adults, larvae and anatomical structures. This volume is based in part on Lawrence & Britton’s out-of-print Australian Beetles, but is fully updated and expanded. The biology and morphology for all major beetle lineages is described and illustrated, along with anatomical terms which clarify the characters and terminology used in the keys; few other resources for beetle identification include such a detailed morphological background. A chapter on the fossil record is also included, and family sections provide full descriptions of adults and larvae, including the world distribution of each family. The revised identification keys (currently recognised as one of the most valuable keys worldwide) will aid quarantine agents, biologists and students in identifying members of the most species-rich order of animals.
