6E7487968254256316B0BC9CFE32A381.taxon	etymology	Etymology: From Latin bulbus, meaning swelling, referring to the shape of the base of the anal point.

The single male was collected in a Malaise trap situated close to a stream and several temporary pools. The area is covered with primary forest and is relatively flat. During the rainy season numerous small pools are formed scattered on the forest floor.
