Abstract

Based on a specimen from the Upper Eocene Baltic amber (Kaliningrad Region, Russia), Aneurops daugpilensis sp. nov. is described. The new species is similar to the extant A. convergens (Sharp, 1900) and A. championi Sharp, 1900 distributed in North and Central America, but differs in the larger punctation of pronotum, and shorter and sparser setation of the median plaque on ventrite 1. Aneurops daugpilensis sp. nov. is distinguished from Europs insterburgensis Alekseev, 2014 by having a median plaque on ventrite 1, a larger body size, and distinctly sparser punctation of the forebody.

摘要

基于一块来自上始新世波罗的海琥珀（俄罗斯加里宁格勒地区）的标本，描述了新物种多格皮尔无脉叩甲（Aneurops daugpilensis sp. nov.）。该新物种与分布于北美洲和中美洲的现存物种汇聚无脉叩甲（A. convergens，夏普，1900年）及钱氏无脉叩甲（A. championi夏普，1900年）相似，但前胸背板的刻点较大，第1腹板上的中斑毛较短且稀疏，与之不同。多格皮尔无脉叩甲（Aneurops daugpilensis sp. nov.）与2014年的因斯特堡欧洲叩甲（Europs insterburgensis Alekseev）的区别在于，其第1腹板上有中斑、体型较大且前体刻点明显较稀疏。
