Diganta.. you must trust Martin... he is expert on Arthropods. http://en.wikipedia.org/wiki/Mantispidae

This does look like the correct ID for your mantis lacewing http://bugguide.net/node/view/538261/bgpage

Nice mantis lacewing. Here's a similar one I found that seems very similar even over a long distance. http://www.projectnoah.org/spottings/8190334

Really cool and different!

I don't know what species you have there, but would agree that it is a mantidfly of some sort from the Family Mantispidae.

Some sort of fly that mimics mantids

Something from Mars?!! Different.
