Table 2. Mean p in Recognizing novel cyanobacterial diversity in marine benthic mats, with the description of Sirenicapillariaceae fam. nov., two new genera, Sirenicapillaria gen. nov. and Tigrinifilum gen. nov., and seven new species

Table 2. Mean p -distance (percentage of genetic similarity) between and within (last column) established cyanobacterial families, based on 16S rRNA gene sequences. Values are based on an alignment of 91 taxa and 7 established cyanobacterial families including the novel family Sirenicapillariaceae with eight genera: Affixifilum, Capilliphycus, Lyngbya, Limnospira, Limnoraphis, Neolyngbya, Sirenicapillaria and Tigrinifilum. Taxonomic family classifications were based on Guiry & Guiry (2021) and Hauer & Komárek (2021). 1234567Within1Sirenicapillariaceae97.202Oscillatoriaceae sensu stricto92.6298.353Laspinemataceae94.3993.6598.414Microcoleaceae94.5193.9894.7798.685Desertifilaceae93.1391.8391.6992.1195.256Vermifilaceae93.9692.4392.8294.6791.6398.017Spirulinaceae92.9791.5892.8193.0592.3391.8794.668Coleofasciculaceae94.5493.5693.6494.5493.6393.6193.8799.80
