1997年11月至2007年2月间对琵琶湖的采样显示，该湖有18种Candonidae动物群。其中11种是以前未描述的物种，属于Fabaeformiscandona（9种），Pseudocandona（1种）和Cypria（1种），其中10种可能是湖泊特有的。根据下颚须上刚毛的数量，湖中共有12种蚕豆，属于两个亚组，蚕豆组（10种）和尖叶组（2种）。包括本文所述的新的蚕豆属物种在内，琵琶湖是全球已知的该属约62种已知物种中19%的家园。虽然，新的Fabaeformiscandona物种是潜在的地方性，他们没有表现出类似的微进化模式，建议为Tanganyikan Cyprideis种群。
Sampling of Lake Biwa between November 1997 and February 2007 has revealed a diverse Candonidae fauna consisting of 18 species. Eleven are previously undescribed species, belonging to the genera Fabaeformiscandona (nine species), Pseudocandona (one species) and Cypria (one species), and 10 of these are potentially endemic to the lake. In total there are 12 Fabaeformiscandona species in the lake belonging to two sub‐groups based on the number of setae on the mandible palp, the fabaeformis‐group (10 species) and the acuminata‐group (two species). Including the new Fabaeformiscandona species described herein, Lake Biwa is home to 19% of the approximately 62 described living species of this genus known globally. Although, the new Fabaeformiscandona species are potentially endemic, they do not show a microevolutionary pattern similar to that suggested for the Tanganyikan Cyprideis species flock.
