Aspidytidae
Aspidytidae is a family of aquatic beetles of the suborder Adephaga, described in 2002 from specimens in South Africa and China. There are only two known species in the family and these were originally described in the genus '' Aspidytes,''Beutel, R.G., Balke, M. & Ribera, I. (2016) 7.7. Aspidytidae Ribera,Beutel, Balke and Vogler, 2002. In: Beutel, R.G. & Leschen, R.A.B. (eds.): ''"Handbook of Zoology, Arthropoda: Insecta. Coleoptera, Beetles.

Walter de Gruyter, Berlin. pp. 141-149. but later the new genus '' Sinaspidytes'' was erected for the species found in China''.'' The family can also be referred to by its trivial name cliff water beetles. Description Cliff water beetles have a streamlined body that is dorsally convex. Their size ranges from 4.8 - 7.0 mm in length. Dorsal side is predominantly black and cuticle is shiny. The head is laterally rounded and shortened w ...

Sinaspidytes Wrasei
''Sinaspidytes'' is a genus of aquatic beetles in Aspidytidae, first recorded in 2003 from specimens in the Shaanxi, Shaanxi province, China. It is monotypic, with the only species being ''Sinaspidytes wrasei''.

Adephaga
The Adephaga (from Greek ἀδηφάγος, ''adephagos'', "gluttonous") are a suborder of beetles, and with more than 40,000 recorded species in 10 families, the second-largest of the four beetle suborders. Members of this suborder are collectively known as adephagans. The largest family is Carabidae (ground beetles) which comprises most of the suborder with over 40,000 species. Adephaga also includes a variety of aquatic beetles, such as predaceous diving beetles and whirligig beetles. Anatomy Adephagans have simple antennae with no pectination or clubs. The galeae of the maxillae usually consist of two segments. Adult adephagans have visible notopleural sutures. The first visible abdominal sternum is completely separated by the hind coxae, which is one of the most easily recognizable traits of adephagans. Five segments are on each foot. Wings The transverse fold of the hind wing is near the wing tip. The median nervure ends at this fold, where it is joined by a ...

Anatomical Terms Of Location
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of ...

Compound Eye
A compound eye is a visual organ found in arthropods such as insects and crustaceans. It may consist of thousands of ommatidia, which are tiny independent photoreception units that consist of a cornea, lens, and photoreceptor cells which distinguish brightness and color. The image perceived by this arthropod eye is a combination of inputs from the numerous ommatidia, which are oriented to point in slightly different directions. Compared with single-aperture eyes, compound eyes have poor image resolution; however, they possess a very large view angle and the ability to detect fast movement and, in some cases, the polarization of light. Because a compound eye is made up of a collection of ommatidia, each with its own lens, light will enter each ommatidium instead of using a single entrance point. The individual light receptors behind each lens are then turned on and off due to a series of changes in the light intensity during movement or when an object in moving, creating a fli ...

Shaanxi Province, China
Shaanxi (alternatively Shensi, see § Name) is a landlocked province of China. Officially part of Northwest China, it borders the province-level divisions of Shanxi (NE, E), Henan (E), Hubei (SE), Chongqing (S), Sichuan (SW), Gansu (W), Ningxia (NW) and Inner Mongolia (N).
