Sarcoplanini
Sarcoplanini is a tribe of land planarians in the subfamily Geoplaninae. Description The tribe Sarcoplanini includes genera of Geoplaninae that occur west of the Andes. They are characterized by the lack of the typical sensory pits that most land planarians have at the border of the anterior region. Instead of this, they have a series of sensory depressions, which are narrower but wider than sensory pits. Most genera also present a retractor muscle at the anterior region that is anatomically distinct from that found in some genera of the tribe Geoplanini. The copulatory apparatus has an extrabulbar prostatic vesicle and musculoglandular organs. Genera The tribe Sarcoplanini contains five genera: *''Liana A liana is a long- stemmed, woody vine that is rooted in the soil at ground level and uses trees, as well as other means of vertical support, to climb up to the canopy in search of direct sunlight.

Geoplaninae
Geoplaninae is a subfamily of land planarians endemic to the Neotropical region. However, one species, ''Obama nungara'' has been introduced in Europe. Description The subfamily Geoplaninae was initially defined by Ogren and Kawakatsu (1990)Ogren, R. E. and Kawakatsu, M. (1990). ''Index to the species of the family Geoplanidae (Turbellaria, Tricladida, Terricola) Part I: Geoplaninae.'' Bulletin of Fujis Women's College. 29: 79-166. for land planarians which have a broad creeping sole, mouth in the second half of the body, dorsal testes, subepithelial longitudinal musculature well developed and parenchymal longitudinal musculature absent or not well developed. The eyes contour the anterior region in a single row and posteriorly form several rows, which may spread onto the dorsum, and extend to the posterior end of the body. However, most, if not all, of these characteristics are not exclusive and cannot be considered a synapomorphy of the group. Some characteristics have also been ...

Land Planarians
Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms. These flatworms are mainly predators of other invertebrates, which they hunt, attack and capture using physical force and the adhesive and digestive properties of their mucus. They lack water-retaining mechanisms and are therefore very sensitive to humidity variations of their environment. Because of their strict ecological requirements, some species have been proposed as indicators of the conservation state of their habitats. They are generally animals with low vagility (dispersal ability) and with very specific habitat requirements, so they can be also used to accurately determine the distribution of biogeographic realms. Today the fauna of these animals is being studied to select conservation priorities in the Atlantic rainforest in Brazil. At the other extreme, one species in this family, ''Platydemus manokwari'' has become an invasive species in both disturbed and wild habitats in the ...

Geoplanini
Geoplanini is a tribe of land planarians in the subfamily Geoplaninae. Description The tribe Geoplanini includes all genera of Geoplaninae that occur east of the Andes plus the Chilean genus '' Transandiplana''. However, there are no currently known synapomorphies uniting these genera, and this group is supported solely on the basis of molecular analyses. Genera The tribe Geoplanini contains 26 genera: *'' Amaga'' *'' Anophthalmoplana'' *''Barreirana'' *'' Bogga'' *'' Cephaloflexa'' *''Choeradoplana'' *'' Cratera'' *''Difroehlichia'' *''Geobia'' *''Geoplana'' *'' Gigantea'' *''Imbira'' *'' Issoca'' *''Liana'' *''Luteostriata'' *'' Matuxia'' *''Notogynaphallia'' *''Obama'' *'' Paraba'' *''Pasipha'' *'' Piima'' *'' Pseudogeoplana'' *'' Supramontana'' *'' Transandiplana'' *'' Winsoria'' *''Xerapoa ''Xerapoa'' is a genus of land planarians from Brazil.

Reproductive System Of Planarians
The reproductive system of planarians is broadly similar among different families, although the associated structures can vary in complexity. All planarians are hermaphrodites, so their reproductive system has a male and a female part. Both parts communicate with the surface of the body via a single opening called gonopore, which is located on the ventral side of the posterior half of the body. Male part of the reproductive system The male part of the reproductive system in planarians has a set of several testicles, distributed throughout the body in two or more rows. They are usually concentrated in the anterior two thirds of the body, although they can reach close to the posterior end. The testicles are connected to a pair of sperm ducts which run posteriorly towards the gonopore. In some groups, the sperm ducts met in their distal part, forming the ejaculatory duct, which then opens in a cavity called “male atrium”. In others, like land planarians, both open i ...

Liana (planarian)
''Liana'' is a genus of land planarians. It is monotypic In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispec ..., being represented by the single species ''Liana guasa'', which occurs in Chile. Description ''Liana'' was defined as land planarians with a broad and elongated body. The cutaneous musculature is strong dorsally and weak ventrally, where it is partially sunk into the mesenchyma. The sensory border has rare and minute sensory pits restricted to the anterior tip. The copulatory apparatus has a short and blunt penis papilla and the female canal enters the genital antrum ventrally.
