Overriding Directory default page for listing_category taxonomy

Directory comes with a listing_category taxonomy for the directory_listing custom post type. While I was successful overriding the default listing page using a archive-listings.php page, I'm not successful overriding the taxonomy page for the listing_category using the template file taxonomy-listing_category.php. Could you please tell me what I have to do to override the default page for the listing_category taxonomy?
