Zoogeographic Affinities of Silverfishes (Zygentoma: Lepismatidae) of India
Keywords:Zygentoma, Ctenolepisma, Lepismatidae, Zoogeographic affinities, Indian fauna
The poorly known Indian fauna of Zygentoma of the family Lepismatidae is presently represented by seventeen species. All these species are known to occur from fourteen States and two Union Territories of India. Available data indicates that absence of records of the family Lepismatidae in almost half of the states. Data concerning the species like Acrotelsa collaris, Ctenolepisma (Ctenolepisma) longicaudatum, Lepisma saccharina, Thermobia domestica are referred only to cosmopolitan synanthrops, therefore without any zoogeographic interest. The Lepismatidae, excluding those species, which are distributed from one country to other due to anthropogenic activities have lost all their zoogeographical weight. The genus Lepidospora with two species and Ctenolepisma alticola these are only known to occur from north-western states. However, the genus Ctenolepisma presents along Africa, Palearctic and Oriental Asia, Mediterranean Europe Australia and Central northern South America. Afrolepisma and Xenolepisma show a clear Afro-Indian distribution. The genus Xenolepisma being exclusive from Cape Province of South Africa and from India are discussed.
