Abstract

A new monotypic genus, Olibrolitus gen. nov. (type species Olibrolituskatyae sp. nov.), is described from Upper Eocene amber. The new genus Olibrolitus does not resemble any extant group of genera of Phalacridae. Several modern genera have been reported and the genus Neolitochropus was recently described from Eocene amber, but the new genus Olibrolitus is not close to Neolitochropus, and it is so far difficult to suggest a connection with any extant genera. The new genus differs from other genera of the family by the absence of elytral striae and the tarsus morphology (the first metatarsomere is longer than the second, articulated loosely).

摘要

一个新的单型属，Olibrolitus属。十一月 （上种始新世琥珀描述）（Olibrolitus katyae sp。nov。类型种）。新的Olibrolitus属与Ph草属的任何现存组都不相似。一些现代属已报告并属Neolitochropus最近从始新世琥珀描述，但新属Olibrolitus不接近Neolitochropus，这是迄今为止难以提出与任何现存属的连接。该新属与该家族的其他属不同，因为它不存在浮游纹和架形态（第一个some骨比第二个some体长，关节松散）。
