| O. V. Vernygora and A. M. Murray 2021 | Member of the genus Armigatus based on the presence of an incomplete series of heart-shaped predorsal scutes. The species is distinguished from the other members of the genus by having a comparably greater body depth, 46e52% of the stan- dard length, 15e17 dorsal fin rays (16 or more in A. brevissimus and A. namourensis, 11e14 in A. oligodentatus and A. dalmaticus); unor- namented bones of the skull roof (compared to the ornamented skull roof of A. brevissimus and A. namourensis), 27 anal pterygiophores (16 or fewer in A. oligodentatus and A. dalmaticus but 24e27 in A. namourensis and 27 or more in A. brevissimus), 33e35 preural centra (31e32 in A. brevissimus, 36e38 in A. namourensis, 35e37 in A. oligodentatus, but 32e35 in A. dalmaticus), and 7e9 predorsal scutes (17e19 in A. namourensis, 10e11 in A. dalmaticus, but 9 in A. brevissimus and A. oligodentatus). |
