11-450: Acarophenacidae is a family of mites in the order Trombidiformes that are egg parasitoids and ectoparasites of beetles or thrips . It contains eight genera and around 40 species. Acarophenacidae are <200 μm in length and elongate to oval in shape. Distinguishing features are the gnathosoma (mouthparts) partially/completely fused into the propodosoma, indistinct palps and the first leg pair being thickest. Acarophenacidae have
22-554: A lack of widespread consensus within the scientific community for extended periods. The continual publication of new data and diverse opinions plays a crucial role in facilitating adjustments and ultimately reaching a consensus over time. The naming of families is codified by various international bodies using the following suffixes: The taxonomic term familia was first used by French botanist Pierre Magnol in his Prodromus historiae generalis plantarum, in quo familiae plantarum per tabulas disponuntur (1689) where he called
33-516: A reduced life cycle , in which the larvae complete their development within their mother; the entire life cycle can take only 4–5 days. Some Acarophenacidae have been suggested as biological control agents as they reduce populations of their hosts. These include Acarophenax mahunkai for the lesser mealworm ( Alphitobius diaperinus ), and Acarophenax lacunatus for red flour beetle ( Tribolium castaneum ) and lined flat bark beetle ( Cryptolestes ferrugineus ).

Family (biology) Family ( Latin : familia , pl. : familiae ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy . It is classified between order and genus . A family may be divided into subfamilies , which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to
55-491: The Genera Plantarum of George Bentham and Joseph Dalton Hooker this word ordo was used for what now is given the rank of family. Families serve as valuable units for evolutionary, paleontological, and genetic studies due to their relatively greater stability compared to lower taxonomic levels like genera and species. Ordo naturalis In botany, the phrase ordo naturalis , 'natural order',
66-526: The Prodromus of de Candolle and the Genera Plantarum of Bentham & Hooker, the word ordo did indicate taxa that are now given the rank of family. Contemporary French works used the word famille for these same taxa. In the first international Rules of botanical nomenclature of 1906 the word family ( familia ) was assigned to this rank, while the term order ( ordo )
77-542: The family Juglandaceae , but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family— or whether a described family should be acknowledged— is established and decided upon by active taxonomists . There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to
88-540: The family as a rank intermediate between order and genus was introduced by Pierre André Latreille in his Précis des caractères génériques des insectes, disposés dans un ordre naturel (1796). He used families (some of them were not named) in some but not in all his orders of "insects" (which then included all arthropods ). In nineteenth-century works such as the Prodromus of Augustin Pyramus de Candolle and
99-575: The seventy-six groups of plants he recognised in his tables families ( familiae ). The concept of rank at that time was not yet settled, and in the preface to the Prodromus Magnol spoke of uniting his families into larger genera , which is far from how the term is used today. In his work Philosophia Botanica published in 1751, Carl Linnaeus employed the term familia to categorize significant plant groups such as trees , herbs , ferns , palms , and so on. Notably, he restricted
110-549: The use of this term solely within the book's morphological section, where he delved into discussions regarding the vegetative and generative aspects of plants. Subsequently, in French botanical publications, from Michel Adanson 's Familles naturelles des plantes (1763) and until the end of the 19th century, the word famille was used as a French equivalent of the Latin ordo (or ordo naturalis ). In zoology ,
121-666: Was once used for what today is a family . Its origins lie with Carl Linnaeus who used the phrase when he referred to natural groups of plants in his lesser-known work, particularly Philosophia Botanica . In his more famous works the Systema Naturae and the Species Plantarum , plants were arranged according to his artificial "Sexual system", and Linnaeus used the word ordo for an artificial unit. In those works, only genera and species (sometimes varieties) were "real" taxa . In nineteenth-century works such as
