Arhynchobdellida
Arhynchobdellida, the proboscisless leeches, are a monophyletic order of leeches. They are defined by the lack of the protrusible proboscis that defines their sister taxon, the Rhynchobdellida.Uttam, Suneha, and Seema Langer.Distribution and Identification key for species of freshwater leech genus Erpobdella Blainville, 1818 (Hirudinida: Arhynchobdellida: Erpobdelliformes: Erpobdellidae)."/ref> Arhynchobdellida is a diverse order, comprimising both aquatic and terrestrial, besides sanguivorous and predatory, leeches. The order is divided into two suborders, Erpobdelliformes and Hirudiniformes (sometimes also called the Pharyngobdelliformes and Gnathobdelliformes, respectively). Taxonomy Historically, the Arhynchobdellida were split into two orders, the Gnathobdellida and the Pharyngobdellida. The Gnathobdellida were jawed and carnivorous of parasitic while the Pharyngobdellida were jawless and carnivorous. Current taxonomy accepts the order Arhynchobdellida and divides into t ...

Leech
Leeches are segmented parasitic or predatory worms that comprise the subclass Hirudinea within the phylum Annelida. They are closely related to the oligochaetes, which include the earthworm, and like them have soft, muscular segmented bodies that can lengthen and contract. Both groups are hermaphrodites and have a clitellum, but leeches typically differ from the oligochaetes in having suckers at both ends and in having ring markings that do not correspond with their internal segmentation. The body is muscular and relatively solid, and the coelom, the spacious body cavity found in other annelids, is reduced to small channels. The majority of leeches live in freshwater habitats, while some species can be found in terrestrial or marine environments. The best-known species, such as the medicinal leech, ''Hirudo medicinalis'', are hematophagous, attaching themselves to a host with a sucker and feeding on blood, having first secreted the peptide hirudin to prevent the blood from c ...

Erpobdellidae
Erpobdellidae is a family of leeches. It is one of the four families belonging to the suborder Erpobdelliformes of the proboscisless leeches order, Arhynchobdellida. Their members have abandoned the blood feeding habits of their ancestors and are instead predators of aquatic invertebrates. The family previously contained seven genera, but Siddall (2002) synonymized five genera (''Croatobranchus'', ''Dina'', ''Mooreobdella'', ''Trocheta'' and ''Nephelopsis'') into the genus '' Erpobdella'' based on morphogenetic analysis, with the remaining genus ''Motobdella'' possibly a sister group and thus retained. This decision was not accepted by scientific community. The family currently contains 3 genera ''Erpobdella'', ''Dina'' and ''Motobdella''. The genus '' Mimobdella'' was also sometimes included within Erpobdellidae or Gastrostomobdellidae Gastrostomobdellidae is a family of annelids belonging to the order Arhynchobdellida.

Mimobdella Buettikoferi
The Kinabalu giant red leech (''Mimobdella buettikoferi'') is a large bright orange-red coloured leech that is endemic to Mount Kinabalu, Borneo. It can grow to a length of over . Etymology The holotype was collected by Johann Büttikofer, and the specific name ''buettikoferi'' is derived from his surname. Ecology The Kinabalu leech is not hematophagic and feeds only on worms such as the Kinabalu giant earthworm, ''Pheretima darnleiensis''. It lives in the damp leaf litter and soil that often accumulates in fissures. It can be found in Kinabalu Park at an elevation of where the trail runs over a rocky outcrop near to the Mempening and Paka Cave shelters. It is usually seen during or after heavy downpours. Phillipps, A. & F. Liew 2000. ''Globetrotter Visitor's Guide – Kinabalu Park''. New Holland Publishers (UK) Ltd. Taxonomy Kinabalu giant red leech is currently classified under the genus ''Mimobdella'' of the family Salifidae. However Nakano (2011) has questioned its incl ...

Americobdella
''Americobdella'' is a genus of carnivorous leeches from southern Chile, comprising only the species ''Americobdella valdiviana''. Taxonomy Philippi, who originally classified ''A. valdiviana'' as an erpobdellid leech, noted that ''Americobdella valdiviana'' was similar to '' Trocheta'' (now synonymized with ''Erpobdella'') "in both appearance and habit". It is phylogenically between two major groups of leeches, the Rhynchobdellida and the Arhynchobdellida. Recent work has suggested ''A. valdiviana'' is more closely related to the Erpobdelliformes than the Hirudiniformes. Description ''Americobdella valdiviana'' is a predator and has only rudimentary jaws. Because of these features, it was originally classified as an erpobdellid leech. ''A. valdiviana'' is grey-coloured on the dorsal side with a yellowish ventral side. Whether eyes are present in this species is a matter of debate. While Philippi originally described ''Americobdella valdiviana'' as having no eyes, other author ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') 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 the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Suborder
Order ( la, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
