Question: Berkheya and Conicosia are examples of which taxonomic category?

Context paragraphs:
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.

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.

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.

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.

Berkheya: Berkheya is a genus of flowering plants in the aster family, Asteraceae, and the subfamily Carduoideae, the thistles.  It is distributed in tropical Africa, especially in southern regions.  Of about 75 species, 71 can be found in South Africa.

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.

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

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".

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.

Conicosia: Conicosia is a genus of succulent plants in the ice plant family native to southern Africa.  They are known commonly as narrow-leafed ice plants.  These are relatively short-lived perennials with underground stems and tentacle-shaped, dull-pointed triangular leaves.  They bear large tubular flowers often exceeding 10 centimeters in width, with up to 250 fringelike petals arranged in a ring around a center with hundreds of stamens.  The fruit is a capsule which opens when it gets wet, slowly releasing the hundreds of tiny seeds as they fall out of its drying flesh.
