Narrative:

Upon taxi in after flight segment (sbn-day) I made a left turn into gate at dtw to taxi up to jetway. The ground 'marshaller' with orange wands was already standing there to wave me in. Upon turning onto the yellow line, all my attention was then directed to the marshaller. About 20-30 ft from the gate the aircraft lurched suddenly where upon the marshaller then gave the signal to stop. The aircraft at that point had already made contact with a de-icing truck parked at next gate, damaging the left wing tip. After aircraft was deplaned and debriefing took place on the ground, the ground marshaller did verbally admit that he had not paid attention to the wing walkers on side of aircraft trying to tell him to direct us to stop aircraft. As PIC of this flight, I only followed his standard hand signals as per our airline SOP's as I taxied slowly into the gate with only 1 engine running at the time of occurrence. Supplemental information from acn 203372: after deplaning, the wing walker reported to me that he tried to signal a stop, but the marshaller did not look and did not see his signal.
