Multiple origin of the Phaenonotum beetles in the Greater Antilles (Coleoptera: Hydrophilidae): phylogeny, biogeography and systematics
<p>The systematics and the phylogenetic position of the Caribbean representatives of <em>Phaenonotum</em> Sharp (Coleoptera: Hydrophilidae) are investigated in order to understand the composition of the Caribbean fauna and its origin. Phylogenetic analysis based on mitochondrial and nuclear genes has revealed the Caribbean species to be situated in three deeply nested clades, inferring multiple colonization of Caribbean islands from the continent. Time-tree analysis and BioGeoBEARS analyses of ancestral ranges estimated the oldest clade, consisting of wingless single-island endemics of Cuba (<em>P. delgadoi</em>), Jamaica (<em>P. ondreji</em> <strong>sp. nov.</strong>) and Hispaniola (<em>P. laterale</em> <strong>sp. nov.</strong>), to have diverged ca. 46.6 Ma from the South American ancestor and subsequently colonizing the Caribbean most likely via the GAARlandia land bridge connecting South America with Greater Antilles. The remaining three Caribbean species, including the Puerto Rican endemic, <em>P. borinquenum</em> <strong>sp. nov.</strong>, are of more recent (Miocene to Pliocene) origin and colonized the Greater Antilles by over-water dispersal. All the Caribbean species are illustrated and diagnosed and three new species are described. The genus <em>Phaenonotum</em>, excluding <em>P. caribense</em> Archangelsky, is confirmed as a monophylum. We demonstrate that species-level taxonomy of <em>Phaenonotum</em> is difficult to solve by morphology alone, and ideally requires the combination of morphology and molecular markers.</p>
Neotropical leaf-litter beetle genus Motonerus (Coleoptera: Hydrophilidae): new species, distribution data and description of third instar larva
<p>Numerous new material of the genus <em>Motonerus </em>Hansen, 1989 (Coleoptera: Hydrophilidae: Sphaeridiinae) was examined over the past decade, resulting in the discovery of several undescribed species as well as new distributional records for most of the previously described species. Three species are here described as new: <em>Motonerus explanatus </em>sp. nov. (Panama), <em>M. inca </em>sp. nov. (Venezuela, Ecuador, Peru, Bolivia) and <em>M. sofiae </em>sp. nov. (Peru). New country records are provided for <em>M. depressus </em>Fikáček & Short (new for Venezuela, Ecuador, Peru and Bolivia), <em>M. hanseni </em>Fikáček & Short (new for Panama) and <em>M. problematicus </em>Fikáček & Short (new for Panama). An updated identification key and distributional maps are provided for all species, along with complete occurrence data in a DarwinCore formatted file. Potential distribution of the genus is modelled using the maximum entropy approach. Wing morphology is examined in detail, which revealed most species are macropterous, with <em>M. andersoni </em>Fikáček & Short being brachypterous, and <em>M. apterus </em>Fikáček & Short, <em>M. oosternoides </em>Fikáček & Short and <em>M. explanatus </em>sp. nov. micropterous. The third instar of the putative larva of <em>M. obscurus </em>Hansen is briefly described based on larvae collected in association with adults.</p>
