This case nicely demonstrates a short chain of proglottids and egg (expressed from the proglottids) of Bertiella - a tapeworm of non-human primates that only rarely infects humans. You can read more about this fascinating parasite at the CDC DPDx website.
The proglottids are very short and wide, thus giving this small segment of proglottids the appearance of 'bow tie' pasta as several of my readers pointed out! (arrows point to some of the individual proglottids)
