Helsdingenia ceylonica, is a species of spider of the genus Helsdingenia . It is found only in Nepal and Sri Lanka. [1]
The order Embioptera, commonly known as webspinners or footspinners, are a small group of mostly tropical and subtropical insects, classified under the subclass Pterygota. The order has also been called Embiodea or Embiidina. More than 400 species in 11 families have been described, the oldest known fossils of the group being from the mid-Jurassic. Species are very similar in appearance, having long, flexible bodies, short legs, and only males having wings.
Cryptothele is a spider genus with eight described species, now placed in the family Zodariidae.

Naria nebrites, common name the false margined cowry, is a species of sea snail, a cowry, a marine gastropod mollusk in the family Cypraeidae, the cowries.
Spiders are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every habitat with the exceptions of air and sea colonization. As of July 2019, at least 48,200 spider species, and 120 families have been recorded by taxonomists. However, there has been dissension within the scientific community as to how all these families should be classified, as evidenced by the over 20 different classifications that have been proposed since 1900.
Tricholophia ceylonica is a species of beetle in the family Cerambycidae, and the only species in the genus Tricholophia. It was described by Stephan von Breuning in 1938.
Prenolepis ceylonica is a species of ant in the subfamily Myrmicinae found in the Philippines, India, Bangladesh, Sri Lanka, and China.
Colobopsis ceylonica is a species of formicine ant. It is found from Sri Lanka.
Pheidole ceylonica is a species of ant in the subfamily Myrmicinae. It is found in Sri Lanka.
Phrynarachne is a genus of crab spiders first described by Tamerlan Thorell in 1869.
Helsdingenia is a genus of dwarf spiders that was first described by Michael I. Saaristo & A. V. Tanasevitch in 2003. The name is a reference to Dr. P. J van Helsdingen.
Phrynarachne ceylonica, the bird dung spider, is a species of spiders of the genus Phrynarachne. It is found in China, Japan, Sri Lanka and Taiwan. The species is known to discharge foul smell, which may help it attract prey and deter predators. Its morphology is similar to bird's dung, and hence its common name. This strategy is used by the spider to catch prey who thinks that it is actually dung, not an animal.
Ceylania ceylonica is a species of beetle in the family Cerambycidae, and the type species of its genus. It was described by Stephan von Breuning in 1979. It is known from Sri Lanka.
Parasosibia ceylonica, is a species of phasmid or stick insect of the genus Parasosibia. It is found in Sri Lanka.
Sipyloidea ceylonica, is a species of phasmid or stick insect of the genus Sipyloidea. It is found in Sri Lanka.
Oxymacaria ceylonica is a moth of the family Geometridae first described by George Hampson in 1902. It is found in Sri Lanka.
Cricula ceylonica, the Sri Lankan cricula silkmoth, is a moth of the family Saturniidae. The species was first described by Karl Jordan in 1909 and it is endemic to Sri Lanka. The debate of this species with much broader range circular species - Cricula trifenestrata is not yet fully understood. However, Rougerie et al., in 2009 considered Cricula ceylonica a valid species, probably endemic to Sri Lanka.
