Single-Cell DNA barcoding using sequences from the small subunit rRNA and internal transcribed spacer region identifies new species of Trichonympha and Trichomitopsis from the hindgut of the termite Zootermopsis angusticollis.

ABSTRACT: To aid in their digestion of wood, lower termites are known to harbour a diverse community of prokaryotes as well as parabasalid and oxymonad protist symbionts. One of the best-studied lower termite gut communities is that of Zootermopsis angusticollis which has been known for almost 100 years to possess 3 species of Trichonympha (T. campanula, T. collaris, and T. sphaerica), 1 species of Trichomitopsis (T. termopsidis), as well as smaller flagellates. We have re-assessed this community by sequencing the small subunit (SSU) rRNA gene and the internal transcribed spacer (ITS) region from a large number of single Trichonympha and Trichomitopsis cells for which morphology was also documented. Based on phylogenetic clustering and sequence divergence, we identify 3 new species: Trichonympha pos
