Non-monophyly of Plakina may explain the wide variability in morphological characters previously observed in this genus [88].
The general morphological characters we observed for M0880/a (Fig. 1D, E) are similar to the original description [ 14] and a previous study [ 19].
Maximum-parsimony, maximum likelihood and Bayesian analyses of molecular data from two nuclear DNA and six cpDNA regions support the monophyly of Petrocosmea and recover five major clades within the genus, which is strongly corroborated by the reconstruction of ancestral states for twelve new morphological characters directly observed from living material.
Nevertheless, this method is important in evolutionary studies, since this method might provide a different concept; the cladistics analysis prioritizes the primitive and derivative features [ 12], while the morphological analysis prioritizes utmost characters observed in a structure.
Some MK morphological characters were also observed in MR-1-silencing cells.
Samples that could not be assigned a species name were normally single specimens at immature stages, so key morphological characters could not be observed (and, for those barcoded, no perfect match was found in the databases either).
Although subtle morphological variations have been observed in B. harrisoni, these findings require a thorough morphological investigation to assess whether there are diagnostic morphological characters and observable physiological adaptations to acid or alkaline pH conditions which are consistent and congruent with the molecular lineages.
Intraspecific variability was observed in morphological characters, isoenzyme studies, mtDNA, ribosomal gene probes, random amplification of polymorphic DNA (RAPD) and microsatellites.
These similarities are not restricted to overall shape, as might be expected to result from natural selection for squeezing into particular skin structures, but have also been observed in morphological characters that are regarded as diagnostic in taxonomy of Demodicidae.
Septate coenocytic mycelium, swollen sporangiophores, and morphological characters similar to Mortierella sp. were observed in our study.
