Question: Do both Alyogyne and Fatsia belong to the taxonomic category of genus?

Context paragraphs:
Fatsia: Fatsia is a small genus of three species of evergreen shrubs native to southern Japan and Taiwan.  They typically have stout, sparsely branched stems bearing spirally-arranged, large leathery, palmately lobed leaves 20–50 cm in width, on a petiole up to 50 cm long, and small creamy-white flowers in dense terminal compound umbels in late autumn or early winter, followed by small black fruit.

Cladorhiza segonzaci: Cladorhiza segonzaci is a species of sponge in the taxonomic category of Demospongiae.  The body of the sponge consists of a spicule and fibers and is water absorbent.

Cladorhiza inversa: Cladorhiza inversa is a species of sponge in the taxonomic category of Demospongiae.  The body of the sponge consists of a spicule and fibers and is water absorbent.

Eogastropoda: Eogastropoda was a previously used taxonomic category of snails or gastropods, a subclass which was erected by Ponder and Lindberg in 1997.  It was one of two great divisions (subclasses) of the class Gastropoda, the snails.  The other subclass of gastropods was the Orthogastropoda.

Gammaridae: Gammaridae is a family of amphipods.  In North America they are included among the folk taxonomic category of "scuds", and otherwise gammarids is usually used as a common name.

Aptera: Aptera is an obsolete taxonomic category, which included the Apterygota along with various other wingless arthropods.

Heterostropha: Heterostropha was a previously used taxonomic category, an order of sea snails, within the superorder Heterobranchia.  In the most current gastropod taxonomy, that of Bouchet & Rocroi, this taxon is no longer in use.

Sigmurethra: Sigmurethra is a taxonomic category of air-breathing land snails and slugs, terrestrial pulmonate gastropod molluscs.  This is an informal group which includes the majority of land snails and slugs.

Alyogyne: Alyogyne is a genus of flowering plants in the family Malvaceae which are endemic to Australia.  Its species were formerly in the genus Hibiscus but were split off starting in 1863 with "H. hakaeifolius".  In 1915 Lewton transferred "H. cuneiformis" and in Fryxell (1968) "H. pinonianus" and "H. huegelii" followed.  A recent revision has created many new species.

Helleborine: Helleborine is the common name for a number of species of orchid.  It does not correspond to any currently used taxonomic category.  Some of the plants called helleborines are classified in the genus "Epipactis", some in genus "Cephalanthera".  A genus "Helleborine" was formerly recognised but has now been absorbed into the Grass pink genus "Calapogon".
