4-397: Orthorrhapha is a circumscriptional name which historically was used in entomology for an infraorder of Brachycera , one of the two suborders into which the order Diptera , the flies, are divided. As the group was paraphyletic , it has not been used in classifications in the last decade, and is effectively obsolete. However, many catalogs, checklists, and older works still contain
8-547: The diagnostic feature of the particular set of members included. Such names are not ruled by any nomenclature code and are mainly for taxa above the rank of family ( e.g. order or class ), but can be used for taxa of any rank or unranked taxa. Non-typified names other than those of genus or species rank constitute the majority of generally accepted names of taxa higher than superfamily . The standard nomenclature codes regulate names of taxa up to family rank ( i.e. superfamily). There are no generally accepted rules for
12-746: The name. The taxa that used to be in the Orthorrhapha now comprise all of the infraorders in Brachycera excluding the Muscomorpha (= "Cyclorrhapha"). The recent revision of the taxonomy of the order Diptera by Pape et al. revived the name Orthorrhapha. This article related to members of the fly suborder Brachycera is a stub . You can help Misplaced Pages by expanding it . Circumscriptional name In biological classification , circumscriptional names ( Latin : nomina circumscribentia ) are taxon names that are defined by their circumscription ; i.e.
16-460: The naming of higher taxa (orders, classes, phyla, etc. ). Under the approach of circumscription-based (circumscriptional) nomenclatures, a circumscriptional name is associated with a certain circumscription of a taxon without regard of its rank or position. In contrast to circumscriptional nomenclature, some authors advocate introducing a mandatory standardized typified nomenclature of higher taxa. They suggest all names of higher taxa to be derived in
