Abstract:

The cosmopolitan subfamily Acidocerinae (Coleoptera: Hydrophilidae) is one of the largest and most taxonomically challenging lineages of water scavenger beetles. Recent phylogenetic studies have substantially advanced our understanding of acidocerine relationships but also illuminated the twin challenges of poorly delineated generic concepts and a classification broadly incompatible with the phylogeny. Here, these two challenges are addressed by providing a comprehensive synthesis and taxonomic tools for the Acidocerinae, including (1) a brief history and the current state of acidocerine class

Abstract:

The water scavenger beetle genus Tobochares Short & García, 2007 currently contains ten species, including one known but formally undescribed taxon. Although Tobochares was revised in 2017, ongoing fieldwork as well as an expanded concept of the genus has led to the recognition of numerous additional species. Here a combination of morphological and molecular data is presented to review this newly found Tobochares diversity. Fifteen new species are described from South America, bringing the total number of known species to 25: Tobochares akoerio sp. nov. (Suriname), T. arawak sp. nov. (Guya

Abstract:

Omniops gen. n. (Coleoptera: Hydrophilidae: Hydrophilini: Acidocerina) is described for two new species from Papua New Guinea: Omniops fasciatus sp. n. and O. hanseni sp. n. This genus is distinguished from other genera of Hydrophilidae by having the eyes divided into dorsal and ventral portions by an extension of the frons, and by having a row of dense long setae on the labrum. The tribal placement of the new genus and that of Quadriops Hansen are discussed. High resolution digital images are given for each holotype (online versions in color).

Larvae were obtained by laboratory rearing and field collecting; field collected larvae were identified by morphological comparison with those reared in the laboratory. Larval morphology of C. abnormalis corresponds with that of C. nitescens (Fauvel, 1883) except for the serrate ma

Abstract This study summarizes available data on karyotypes of water scavenger beetles (Coleoptera: Hydrophiloidea: Hydrophilidae), based on newly acquired data of 23 genera and 64 species. We combine these data with previously published data, which we review. In total, karyotypes are available for 33 genera and 95 species, covering all subfamilies and tribes. Available data indicate that most groups of the Hydrophilidae are diploid and sexually reproducing, with XY (♂) and XX (♀) sex chromosomes; the Y chromosome is always minute and does not recombine with X during meiosis. Exceptions are kn

Abstract:

Original set of pictures obtained under MicroCT technology and used to reconstruct three-dimensional models of hydrophilid beetles embedded in Baltic amber. Abstract Water scavenger beetles (Coleoptera: Hydrophilidae) are a broadly distributed group with high extant diversity. However, reliable records from Baltic amber (Eocene) are scarce and limited to two undescribed species previously reported in the literature. Here we study these two specimens plus four additional ones. All specimens were sub-optimal in terms of preservation and visibility of their morphology using traditional light
