Abstract

Macroplea japana (Jacoby, 1885) has not been collected in Japan since the 1960s and was thought to be locally extinct. Recently, we collected this species from submerged aquatic plants growing in the nearshore zone of Lake Biwa, Shiga Prefecture, where it had previously been recorded from the stomach contents of pochards in the 1950s. We conducted a molecular phylogenetic analysis to identify the phylogenetic position of the Japanese M. japana within the tribe Haemonini of the Holarctic region, which consists of Macroplea in Eurasia and Neohaemonia in North America. We found that M. japana specimens from Japan and China were genetically close to each other and distantly related to all other known Macroplea species from Asia and Europe, indicating the species identity of the Japanese and Chinese populations and the distinct species status of M. japana.

曾被认为在日本已灭绝的水生叶甲——大斑金龟甲的重新发现
自20世纪60年代以来,日本就没有采集到大斑蝶(Jacoby,1885),人们认为它在当地已经灭绝。最近,我们从滋贺县琵琶湖近海生长的水生植物中收集到了这种物种,在20世纪50年代,人们曾从波恰德人的胃中记录到这种物种。我们进行了分子系统发育分析,以确定日本M.japana在全北极地区Haemonini部落中的系统发育位置,该部落由欧亚大陆的Macropouse和北美的Neohemonia组成。我们发现,来自日本和中国的M.japana标本在基因上彼此接近,而与亚洲和欧洲所有其他已知的大型物种都有远缘,这表明了日本和中国种群的物种身份以及M.japana的独特物种地位。
