Pachymerinus
''Pachymerinus'' is a genus of centipedes in the family (biology), family Geophilidae. It was described by Italian entomology, entomologist Filippo Silvestri in 1905. Centipedes in this genus feature elongate heads, elongate Forcipule, forcipules with Denticle (tooth feature), denticles, scattered coxal pores, and few sternal pores, if any; the intermediate part of the Labrum (arthropod mouthpart), labrum is narrow and has no denticles. These centipedes range from about 3 cm to 8 cm in length, have 47 to 81 pairs of legs, and are found in Chile and southeast Australia. The Australian species ''Pachymerinus froggatti'' is notable for its relatively small size, measuring only 28 mm in length. The larger Chilean species ''P. porteri'' measures 46 mm in length but can have as few as 47 leg pairs (47 to 49 in males, 47 to 51 in females), the minimum number recorded in this genus. The Chilean species ''P. pluripes'' measures only 32 mm in length but can have 79 or 81 leg pairs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pachymerinus Froggatti
''Pachymerinus froggatti'' is a species of centipede in the Geophilidae family. It is endemic to Australia, and was first described in 1912 by French myriapodologist Henry Wilfred Brolemann. Description The original description of this species is based on a single male specimen measuring 28 mm in length with 55 pairs of legs. Distribution The species occurs in coastal New South Wales and Queensland. Behaviour The centipedes are solitary terrestrial predators that inhabit plant litter Plant litter (also leaf litter, tree litter, soil litter, litterfall or duff) is dead plant material (such as leaves, bark, needles, twigs, and cladodes) that have fallen to the ground.

Pachymerinus Australis
''Pachymerinus australis'' is a species of centipede in the Geophilidae family. It is endemic to Australia, and was first described in 1920 by American biologist Ralph Vary Chamberlin. Description The original description of this species is based on a specimen measuring 45 mm in length with 71 pairs of legs. Distribution The species occurs in New South Wales.

Geophilidae
The Geophilidae are a polyphyletic, cosmopolitan family of soil centipedes in the superfamily Geophiloidea containing the mostly defunct clades Aphilodontidae, Dignathodontidae, Linotaeniidae, Chilenophilinae, and Macronicophilidae. Species in this family are characterized by mandibles with a single pectinate lamella, slender antennae, sternal pores with variable arrangement, a generally slightly or moderately elongate head, frequently undivided coxosternite with two paramedian sclerotized lines, claws without rows of filament, and female gonopods usually being an undivided lamina. Compared to most other families in the suborder Adesmata, this family features a modest number of leg-bearing segments (no more than 125) and limited variation in this number within each species. Two species in this family include centipedes with only 29 pairs of legs: '' Geophilus persephones'' (29 pairs in the only specimen, a male), and '' G. richardi'' (29 or 31 pairs in the males and 33 pa ...

Centipede Genera
Centipedes (from New Latin , "hundred", and Latin , "foot") are predatory arthropods belonging to the class Chilopoda (Ancient Greek , ''kheilos'', lip, and New Latin suffix , "foot", describing the forcipules) of the subphylum Myriapoda, an arthropod group which includes millipedes and other multi-legged animals. Centipedes are elongated segmented (metameric) creatures with one pair of legs per body segment. All centipedes are venomous and can inflict painful bites, injecting their venom through pincer-like appendages known as forcipules. Despite the name, centipedes can have a varying number of legs, ranging from 30 to 382. Centipedes always have an odd number of pairs of legs; no centipede has exactly 100. Like spiders and scorpions, centipedes are predominantly carnivorous. Their size ranges from a few millimetres in the smaller lithobiomorphs and geophilomorphs to about in the largest scolopendromorphs. Centipedes can be found in a wide variety of environments.

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. Duplica ...
