Monotypic Genus
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...

Phasmatodea
The Phasmatodea (also known as Phasmida or Phasmatoptera) are an Order (biology), order of insects whose members are variously known as stick insects, stick bugs, walkingsticks, stick animals, or bug sticks. They are also occasionally referred to as Devil's darning needles, although this name is shared by both Dragonfly, dragonflies and Tipuloidea, crane flies. They can be generally referred to as phasmatodeans, phasmids, or ghost insects, with phasmids in the family Phylliidae called leaf insects, leaf-bugs, walking leaves, or bug leaves. The group's name is derived from the Ancient Greek ', meaning an Apparitional experience, apparition or Ghost, phantom, referring to their resemblance to vegetation while in fact being animals. Their natural camouflage makes them difficult for predators to detect; still, many species have one of several secondary antipredator adaptation, lines of defense in the form of startle displays, spines or toxic secretions.

Phasmatidae
The Phasmatidae are a family (biology), family of the stick insects (order (biology), order Phasmatodea). They belong to the Superfamily (zoology), superfamily Anareolatae of suborder Verophasmatodea. Like many of their relatives, the Phasmatidae are capable of regenerating limbs and commonly reproduce by parthenogenesis. Despite their bizarre, even threatening appearance, they are harmless to humans. The Phasmatidae contain some of the largest insects in existence. An undescribed species of ''Phryganistria'' is the longest living insect known, able to reach a total length of 64 cm (25.2 inch). Subfamilies Following the Phasmid Study Group, nine subfamilies are recognized in the Phasmatidae. Other treatments differ, sometimes recognizing as few as six. The Lonchodinae were historically often placed in the Diapheromeridae, the other family (biology), family of the Anareolatae. The Phasmatinae are often expanded to include the two tribe (biology), tribes here separated as the Cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects Described In 1896
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in ves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
