status

 

Genus Stoyanowites Korn View in CoL in Ghaderi et al., 2014

Type species

Paratirolites dieneri Stoyanow, 1910 View in CoL , by original designation

Included species

Stoyanowites aspinosus Korn & Ghaderi in Korn et al., 2016; Paratirolites dieneri Stoyanow, 1910 ; Stoyanowites parallelus Korn & Hairapetian sp. nov.

Diagnosis

Genus of the family Dzhulfitidae with moderately large conch; maximum adult diameters are between 80 and 95 mm. Subadult and adult stages with rectangular and compressed whorl profile. Subadult stage with weak to moderately strong lateral ribs; adult stage with weak ornament. Suture line with an external lobe that is much shorter than the adventive lobe.

Remarks

Stoyanowites is separated from most of the other genera of the family Dzhulfitidae by the short external lobe, which does not reach the depth of the adventive and lateral lobes. Only Dzhulfites is similar in this respect, but this genus is characterised by coarse ventrolateral nodes absent in Stoyanowites .
