Diagnosis: Distinguished from its congeners by the unique combination of the following characters: 7 pairs of gill pouches; 3-cusp multicusps in anterior and posterior rows; 11-13 unicusps in anterior rows; 9 unicusps in posterior rows; 54 total cusps; 14-15 prebranchial pores; 57-58 trunk pores; 13-14 tail pores; 92 total pores; ventral finfold prominent (Ref. 57440).
鑑別: 與下列特徵的組合它的同類區分了: 7個對鰓囊; 三牙尖的在前面與後面的列中; 在前面的列中 11-13 單犬齒; 在後列中的 9個單犬齒; 54個總尖頭; 14-15個前鰓孔; 57-58個軀幹孔; 13-14個尾部孔; 92個總孔; 腹面鰭褶突出的.(參考文獻 57440)
Adult female holotype had dozens of small eggs, 45 X 14 mm, in the mesentery, which was attached to the body wall. The eggs did not have terminal anchor filaments and hooks (Ref. 57440).
