Mecistocephalus Diversisternus
''Mecistocephalus diversisternus'' is a species of soil centipede in the family Mecistocephalidae. This centipede is notable for featuring 57 or 59 pairs of legs rather than the 49 leg pairs usually observed in the genus '' Mecistocephalus''. This centipede is one of only a few species in the genus ''Mecistocephalus'' or in the family Mecistocephalidae with more than 55 leg pairs. This centipede is also one of only a few species in this family to exhibit any variation in leg number among specimens. This species is found from the island of Honshu in Japan to Taiwan. Discovery and taxonomy This species was first described under the name ''Lamnonyx diversisternus'' in 1919 by the Italian zoologist Filippo Silvestri based on a male holotype with 57 pairs of legs, which he collected on the island of Honshu in Japan. The type material is deposited in the Museo Civico di Storia Naturale Giacomo Doria in Genoa, Italy. In 1920, the American biologist Ralph V. Chamberlain placed this sp ...

Filippo Silvestri
Filippo Silvestri (22 June 1873 – 10 June 1949) was an Italian entomologist. He specialised in world Protura, Thysanura, Diplura and Isoptera, but also worked on Hymenoptera, Myriapoda and Italian Diptera. He is also noted for describing and naming the previously unknown order Zoraptera. In 1938 he was nominated to the Pontifical Academy of Sciences, the scientific academy of the Vatican. Silvestri was born in Bevagna. A keen young naturalist, he became assistant to Giovanni Battista Grassi (1854–1925), Director of the Institute of Anatomical Research of the University of Rome. In 1904, Silvestri became Director of the Institute of Entomology and Zoology at the agricultural college in Portici (the Laboratorio di Zoologia Generale e Agraria, now Faculty of Agriculture), a position he held for 45 years. He discovered polyembryony in the 1930s while working on ''Litomatix truncatellus'' Hymenoptera. His collection is in the Museo Civico di Storia Naturale di Genova. Dup ...

Morphology (biology)
Morphology (from Ancient Greek μορφή (morphḗ) "form", and λόγος (lógos) "word, study, research") is the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, color, pattern, size), as well as the form and structure of internal parts like bones and organs, i.e., anatomy. This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of the overall structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Fried ...

Phylogenetics
In biology, phylogenetics () is the study of the evolutionary history of life using observable characteristics of organisms (or genes), which is known as phylogenetic inference. It infers the relationship among organisms based on empirical data and observed heritable traits of DNA sequences, protein amino acid sequences, and morphology. The results are a phylogenetic tree—a diagram depicting the hypothetical relationships among the organisms, reflecting their inferred evolutionary history. The tips of a phylogenetic tree represent the observed entities, which can be living taxa or fossils. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the taxa represented on the tree. An unrooted tree diagram (a network) makes no assumption about directionality of character state transformation, and does not show the origin or "root" of the taxa in question. In addition to their use for inferring phylogenetic pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mecistocephalus Microporus
''Mecistocephalus'' is the largest genus of centipedes in the family Mecistocephalidae, with about 140 species. This genus is among the most diverse and widespread of all the genera in the order Geophilomorpha. The British entomologist George Newport first proposed this genus in 1843 to contain a group of centipedes marked by an unusual elongation of the head. Description Centipedes in this genus range from 2 cm to 10 cm in length. The head, forcipular segment, and their appendages are often elongated, with a head that is obviously longer than wide. A pair of sclerotized teeth (spicula) project from the pleurites on the sides of the head. The coxosternite of the first maxillae is divided down the middle by a longitudinal suture, but the coxosternite of the second maxillae is undivided. The second maxillae reach beyond the first maxillae and are well developed with a simple claw. The forcipular tergum is slightly wider than long and divided down the middle by a longit ...
