  A complex collective emerging behavior characterized by coexisting coherent
and incoherent do- mains is termed as a chimera state. We bring out the
existence of a new type of chimera in a nonlocally coupled ensemble of
identical oscillators driven by a common dynamic environment. The latter
facilitates the onset of phase-flip bifurcation/transitions among the coupled
oscillators of the ensemble, while the nonlocal coupling induces a partial
asynchronization among the out-of-phase synchronized oscillators at this onset.
This leads to the manifestation of coexisting out-of-phase synchronized
coherent domains interspersed by asynchronous incoherent domains elucidating
the existence of a different type of chimera state. In addition to this, a rich
variety of other collective behaviors such as clusters with phase-flip
transition, conventional chimera, solitary state and com- plete synchronized
state which have been reported using different coupling architectures are found
to be induced by the employed couplings for appropriate coupling strengths. The
robustness of the resulting dynamics is demonstrated in ensembles of two
paradigmatic models, namely R\"ossler oscillators and Stuart-Landau
oscillators.
