Hat-tips galore to the Asian tech media for unearthing another taxi app investment - eHi spent $25m this April buying an 8.4% stake in Kuaidi Dache.
The investment was mentioned in eHi's 300-plus-page IPO filing released earlier this month, as reported by Tnooz.
TechNode spotted the mention of eHi's investment and reported on it today.
The filing, which is reported to have been updated, says:

On April 21, 2014, we, through our wholly owned subsidiary, Elite Plus Developments Limited, or Elite Plus, invested US$25 million for subscribing series B preferred shares of Travice Inc., which developed and operates Kuaidi mobile taxi and car calling service provider, representing 8.4% of the then outstanding share capital of Travice Inc.
The Venn diagram of the tech investments gets more complicated by the day. Chinese internet giant Alibaba is a major investor in Kuaidi Dache. Ctrip is the majority investor in eHi, and Priceline has a small but increasing stake in Ctrip.
Over the past week or so, Priceline Inc has been buying up Ctrip shares, as announced to NASDAQ and spotted by TechInAsia. Priceline now owns 7.9% of Ctrip.
