Tanacetum is a genus of about 160 species of flowering plants in the aster family, Asteraceae, native to many regions of the Northern Hemisphere.
 They are known commonly as tansies.
 The name tansy can refer specifically to "Tanacetum vulgare", which may be called the common tansy or garden tansy for clarity.
Cassida denticollis is a species of beetle in the leaf beetle family, that can be found in Mongolia, West China (Xinjiang province), and the Western Palaearctic region.
 The species feeds on plants from the Asteraceae family, including "Achillea millefolium", "Artemisia absinthium", "Artemisia campestris" and various plants "Tanacetum" species, including "Tanacetum corymbosum" and Tansy.
At least seven monkey species are native to Central America.
 An eighth species, the Coiba Island howler ("Alouatta coibensis") is often recognized, but some authorities treat it as a subspecies of the mantled howler, ("A. palliata").
 A ninth species, the black-headed spider monkey ("Ateles fusciceps")is also often recognized, but some authorities regard it as a subspecies of Geoffroy's spider monkey ("A. geoffroyi").
 Taxonomically, all Central American monkey species are classified as New World monkeys, and they belong to four families.
 Five species belong to the family Atelidae, which includes the howler monkeys, spider monkeys, woolly monkeys and muriquis. Two species belong to the family Cebidae, the family that includes the capuchin monkeys and squirrel monkeys.
 One species each belongs to the night monkey family, Aotidae, and the tamarin and marmoset family, Callitrichidae.
Eustoma, commonly known as lisianthus or prairie gentian, is a small genus in the gentian family.
 They are native to warm regions of the southern United States, Mexico, Caribbean and northern South America.
 This genus is typically found in grasslands and in areas of disturbed ground.
Tanacetum camphoratum is a species of flowering plant in the aster family known by the common names camphor tansy and dune tansy.
 It is native to the Pacific Coast of North America from British Columbia to California, where it grows in sand dunes and other coastline habitat.
 This species may be known by the synonym "Tanacetum douglasii" and is often included in "Tanacetum bipinnatum".
 It is a rhizomatous perennial herb with a thick, low-lying stem up to 25 centimeters long, branching to form a mass of vegetation.
 It is hairy, glandular, and aromatic, with a camphor scent.
 The leaves are up to 25 centimeters long and thick but featherlike, divided into many narrow leaflets on each side of the main rachis.
 Each leaflet in turn has many segments along each side, and the segments are usually divided into several small, knobby segments with folded or curled edges.
 The inflorescence bears up to 15 flower heads, each about a centimeter wide or slightly wider.
 Each head contains many yellowish disc florets and many pistillate florets around the edges.
 The latter may have minute ray florets.
 The fruit is an achene a few millimeters long which is tipped with a small pappus of toothed scales.
At least six monkey species are native to Panama.
 A seventh species, the Coiba Island howler ("Alouatta coibensis") is often recognized, but some authors treat it as a subspecies of the mantled howler, ("A. palliata").
 An eighth species, the black-headed spider monkey is also often recognized, but some authorities regard it as a subspecies of Geoffroy's spider monkey.
 All Panamanian monkey species are classified taxonomically as New World monkeys, and they belong to four families.
 The Coiba Island howler, mantled howler, black-headed spider monkey and Geoffroy's spider monkey all belong to the family Atelidae.
 The white-headed capuchin and Central American squirrel monkey belong to the family Cebidae.
 the family that includes the capuchin monkeys and squirrel monkeys.
 The Panamanian night monkey belongs to the family Aotidae, and Geoffroy's tamarin belongs to the family Callitrichidae.
Stereopsis is the sole genus of fungi in the family Stereopsidaceae.
 The genus was formerly placed in the family Meruliaceae in the order Polyporales but was found to belong in its own order along with the genus "Clavulicium".
 "Stereopsis" was circumscribed by English mycologist Derek Reid in 1965.
 It contains species that form funnel-shaped basidiocarps as well as the corticioid species "Stereopsis globosa" which was formerly considered a species of "Clavulicium".
 The species "Stereopsis humphreyi" and "Stereopsis vitellina" were found to belong in the Agaricales and Atheliales respectively in a molecular phylogenetics study, and because of this do not belong in "Stereopsis", but they have not yet been transferred to their own genera.
Tansy ("Tanacetum vulgare") is a perennial, herbaceous flowering plant of the aster family, native to temperate Europe and Asia.
 It has been introduced to other parts of the world including North America, and in some areas has become invasive.
 It is also known as common tansy, bitter buttons, cow bitter, or golden buttons.
Eustoma russellianum, is a species of flowering plant in the Gentian family.
 Its previous binomial name was "Eustoma grandiflorum".
 Common names include Texas bluebells, Texas bluebell, bluebell, showy prairie gentian, prairie gentian The Bolero Deep Blue, and Lisianthus.
Toktokkies are a variety of species of beetles that belong to the large Tenebrionidae family, also known as Darkling beetle.
 Toktokkies do not belong to a particular tribe or genus of Tenebrionids, but rather a selection of flightless species with distinct tapping noises.
 The Tenebrionidae family to which these beetles belong is quite large, with almost 3,500 species inhabiting Southern Africa.
 Nearly 200 species of Toktokkies inhabit the country of Namibia and 20 have adapted to the extreme temperatures of the Namib Desert.
 The most common Toktokkies in the Namib Desert are the Fog Basking beetle ("Onymacris unguicularis") and the button beetle or trench-digging beetle ("Lepidochora discoidalis").

Question: Do the genuses Tansy and Eustoma belong to the same family?
Answer: no
