03FB8791FFDA0918FF3EFB1CFE6CFEFD.taxon	diagnosis	Diagnosis (from Petrushevskaya 1981 p. 121): The shell is swollen at the junction of the cephalis and trilobate thorax; the cephalis partly immersed in a trilobate thorax; the eucephalic chamber is hemispherical or spherical; the cephalis belongs to the type II (following Petrushevskaya 1981); the lateral lobes of the cephalis and its postcephalic lobe, fused with the thorax, are often well developed; the lobes are separated by furrows formed by the junction of spines D, L l, and L r with the thoracic wall; those spines partly protrude outside the wall from these grooves as external appendages; the spine A protrudes outside as the Apical horn, which has the width similar to the spines D, L l, and L r; it comes out subapically at the junction of the eucephalic chamber with the lateral lobes; the Axobate (Ax) is short or not developed; the thorax (II segment) is often approximately equal in length to cephalis (I segment) if measured from MB, but thorax (II segment) can be quite long, cylindrical in its distal part, bearing unstable constrictions, dividing it into 2 – 3 sections; the wall is hyaline; the pores are disordered, smaller in the upper part, becoming larger towards the mouth; the mouth is often open, unformed. Note 2: External parts of the spines are often broken off. This was the case with A. Popofsky’s specimen (Petrushevskaya 1981 p. 121).

03FB8791FFDA0918FF3EFB1CFE6CFEFD.taxon	etymology	Etymology: for the external morphology of genus members resembling four balls of sherbet, one lying above the other three, slightly thawed, flowing over one another and forming a veil below; portmanteau from English sherbet (frozen dessert of fruit juice with dairy products) — a word with a multistage history of borrowing: from Arabic ش َ ر ْ ب َ ة [šarba] through Persian تبرش [šarbat], Ottoman Turkish تبرش [şerbet], and, finally, Turkish şerbet — and Ancient Greek τετρα (tetra) — four. Grammatical gender is feminine. Zoobank LSID: urn: lsid: zoobank. org: act: D 590 CF 86 - 92 C 7 - 47 CE-A 7 A 5 - 41 A 7 AE 1 E 1 CE 4	en	Shɨshkin-Skarð, Yegor (2024): Sherbetra nom. n.

03FB8791FFDA0918FF3EFB1CFE6CFEFD.taxon	type_taxon	Type species: Trisulcus triacanthus Popofsky 1913 — original binomen (in accordance with Recommendation 67 B of ICZN); now Sherbetra triacantha (Popofsky 1913) comb. n. Note 3: Petrushevskaya (1975) lumped Trisulcus Popofsky 1913 with Botryopera Haeckel 1887. Nevertheless, this was done partly (three non-type species of Trisulcus). Soon she clearly distinguished Trisulcus and Botryopera in Petrushevskaya & Kozlova (1979 p. 122) and Petrushevskaya (1981), as do Renaudie & Lazarus (2012; 2013), Trubovitz et al. (2022), and other authors.	en	Shɨshkin-Skarð, Yegor (2024): Sherbetra nom. n.
