The phylogenetic analyses using multiple genes would be helpful in the treatment of systematic position at subgenus/section levels.
Based on these results, the systematic position of the genus Hyalodiscus could be finally clarified, accompanied by the revision of relevant diagnoses and a taxonomic summary.
However, the precise systematic position of Bourreria within Ehretiaceae cannot be resolved on the basis of the morphological data provided here.
Molecular identification of the strain was carried out using 16S rRNA analysis and their systematic position was ascertained as Arthrospira platensis RRGK.
Due to this huge variability, the systematic position of this taxon has been reviewed many times in the last two decades.
The number of endocycles in cells is genetically predetermined and the degree of endopolyploidy is subject to the systematic position of the given species (Barow and Meister 2003; Bainard et al. 2012).
The latest assessment of brain anatomy in tardigrades likewise constrains their systematic position to either sister group of Onychophora + Arthropoda, as in Fig. 2B, or closer to Cycloneuralia (Zantke et al. 2008), as in Fig. 2A.
The systematic position of Fuxianhuiida, an early Cambrian group from China, in the arthropod stem group has received broad consensus (Chen et al. 1995; Hou and Bergström 1997; Budd 2002, 2008; Bergström and Hou 1998, 2005; Waloszek et al. 2005, 2007), despite varying interpretations of head structures.
Studies of the ultrastructure of the sporocarps suggests that Barbeyella occupies a systematic position intermediate between Echinosteliales and the Stemonitales.
However, in a detailed monography on the osteology, systematic position and palaeobiology of Kentrosaurus in 1925, Hennig picked the most complete partial skeleton, today inventorized as MB.R.4800.1 through MB.R.4800.37, as a lectotype (see syntype).
Our numerical analyses could not fully resolve the systematic position of Zhuchengceratops (Figure 9).
