All new genus-group names included in Gistel's list of Coleoptera from the collection of Count Rudolph von Jenison Walwort, published in 1834, are recorded. For each of these names, the originally included available species are listed and for those with at least one available species included, the type species and current status are provided. The following new synonymies are proposed [valid nam...

The resolution of phylogenetic relationship among animals is still one the most challenging problems in systematic zoology. Insect wing a highly valued morphological character systematics, but few studies have been conducted to quantify shape variations for reconstruction. In this study, with Cantharinae as subject, we GM analyses from hindwings 16 representative genera. Further, UPGMA based on...
