Question: Sanguinaria and Stachyurus, are a genus of which type?

Context paragraphs:
Russula sanguinaria: Russula sanguinaria, commonly known as the bloody brittlegill, is a strikingly coloured mushroom, a member of the "Russula" genus, which has the common name of brittlegills.  It is bright blood-red, inedible, and grows in association with coniferous trees.  It was previously widely known as "Russula sanguinea".

Chelidonium: Chelidonium majus, commonly known as greater celandine or tetterwort,(although tetterwort also refers to "Sanguinaria canadensis"), nipplewort, or swallowwort, is a herbaceous perennial plant, the only species in the genus Chelidonium.  It is native to Europe and western Asia and introduced widely in North America.

Stachyurus: Stachyurus is the only genus in the flowering plant family Stachyuraceae, native to the Himalayas and eastern Asia.  They are deciduous shrubs or small trees with pendent racemes of 4-petalled flowers which appear on the bare branches before the leaves.  The plants have leaves with serrate margins.  Stachyuraceae contains a single genus with eight species.

Styporaphidia: Styporaphidia is a genus of snakefly, belonging to the extinct family Mesoraphidiidae, containing up to two species, the type species Styporaphidia magia and tentatively Styporaphidia?  hispanica.  The genus was named from the Greek "stypos" meaning "stem" or "stump" and "Raphidia", the type genus for, and most often used as, a stem for generic names in the order Raphidioptera.  The species name of "S. magia" is from the Greek word "mageia" meaning "magic" while the species name for "S.?  hispanica" is from the Latin "Hispania" meaning "Spain" in reference to the type locality of the species.

Name-bearing type: Under the "International Code of Zoological Nomenclature" ("Code"), the name-bearing type is the biological type that determines the application of a name.  Each taxon regulated by the "Code" at least potentially has a name-bearing type.  The name-bearing type can be either a type genus (family group), type species (genus group), or one or more type specimens (species group).  For example, the name "Mabuya maculata" (Gray, 1839) has often been used for the Noronha skink (currently "Trachylepis atlantica"), but because the name-bearing type of the former, a lizard preserved in the Muséum national d'histoire naturelle in Paris, does not represent the same species as the Noronha skink, the name "maculata" cannot be used for the latter.

Deinocheiridae: Deinocheiridae is a family of ornithomimosaurian dinosaurs, living in Asia from the Albian until the Maastrichtian.  The family was originally named by Halszka Osmólska and Roniewicz in 1970, including only the type genus "Deinocheirus".  In a 2014 study by Yuong-Nam Lee and colleagues and published in the journal "Nature", it was found that Deinocheiridae was a valid family.  Lee "et al." found that based on a new phylogenetic analysis including the recently discovered complete skeletons of "Deinocheirus", the type genus, as well as "Garudimimus" and "Beishanlong", could be placed as a successive group, with "Beishanlong" as the most primitive and "Deinocheirus" as most derived.  The family Garudimimidae, named in 1981 by Rinchen Barsbold, is now a junior synonym of Deinocheiridae as the latter family includes the type genus of the former.  The group existed from 115 to 66 million years ago, with "Beishanlong" living from 115 to 100 mya, "Garudimimus" living from 100 to 83 mya, and "Deinocheirus" living from 71 to 66 mya.

Sanguinaria: Sanguinaria canadensis (bloodroot) is a perennial, herbaceous flowering plant native to eastern North America.  It is the only species in the genus Sanguinaria, included in the family Papaveraceae, and most closely related to "Eomecon" of eastern Asia.

Dakotasuchus: Dakotasuchus (meaning "Dakota [Sandstone] crocodile") is a genus of goniopholidid mesoeucrocodylian. Its fossils have been recovered from the Cenomanian-age Upper Cretaceous Dakota Sandstone of Kansas.  The type specimen was found in an iron-cemented sandstone concretion near Salina.  This concretion was broken into two large pieces; more of the specimen was probably present originally, but by the time it was found only the torso and short portions of the neck and tail remained.  Twenty pairs of bony scutes ran down the midline of the back.  The vertebrae lacked the procoelous articulation (concave anterior and convex posterior faces) of more derived crocodyliforms.  "Dakotasuchus" had short broad shoulder blades, suggesting it had stout powerful forelimbs and perhaps terrestrial habits.  M. G. Mehl, who described the genus, estimated the length of the type individual when complete to have been 3 - .  The type species is "D. kingi", named for Professor King, a former dean of Kansas Wesleyan University.  Mehl did not classify his new genus to a more inclusive group than Mesosuchia (a paraphyletic group replaced by Mesoeucrocodylia).  Robert Carroll assigned "Dakotasuchus" to Goniopholididae in 1988.

Casuarictin: Casuarictin is an ellagitannin, a type of hydrolysable tannin.  It can be found in "Casuarina" and "Stachyurus" species.

Hintzeia: Hintzeia is a genus of trilobites in the order Phacopida (family Pliomeridae), that existed during the lower Ordovician in what is now the United States.  It was described by Harrington in 1957, and the type species is "Hintzeia aemula" (type specimen: 26434 (AMNH)), which was originally described under the genus "Protopliomerops" by Hintze in 1953.  Harrington also moved two other "Protopliomerops" species, "P. celsaora" and "P. firmimarginis", under "Hintzeia".  The generic name is derived from that of the type species' author.  The type locality was the Fillmore Formation in Utah.
