''Placobdelloides '' is a genus of glossophoniid leeches. Description Species of ''Placobdelloides'' lack a jaw and usually feed with a protrusible proboscis; they are predacious or sanguivorous, or both, on a variety of prey such as shrimps, waterfowl, fish, amphibians, turtles, crocodiles or mammals.

Placobdelloides Siamensis
''Placobdelloides siamensis '' is a species of blood-feeding jawless leech in the family Glossiphoniidae.Oka, A. 1917. Zoological Results of a Tour in the Far East, pt. III. Hirudinea. Memoirs of the Asiatic Society of Bengal, VI, pp. 157-176, pl. VII.Sawyer, R.T. 1986: Leech biology and behaviour. Volume II. Feeding biology, ecology, and systematics. Clarendon Press, Oxford. It is commonly known as the Siam shield leech and is a prevalent ectoparasite on Malayemys turtles but has a range of Geoemydidae hosts. In high numbers it can cause severe anaemia and malnutrition which can lead to the death of its host. Taxonomy The species was first described as ''Hemiclepsis siamensis'' by Oka in 1917 then transferred by Sawyer to his new genus '' Placobdelloides'' in 1986. In 2018, it was redescribed from specimens collected in Thailand. Hosts The type host is the Black Marsh Turtle, '' Siebenrockiella crassicollis''. Other hosts include the Southeast Asian Box Turtle, ''Cuora amboi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...
