Pygoda Ramosa
''Pygoda ramosa'' is a species of stink bug in the family Pentatomidae. It was first described in 2018 and is found in the canal area in Panamá. ''Pygoda ramosa'' measures between 19—21mm in length and green above. It is characterized by a pronotum and Scutellum (insect anatomy), scutellum with dark brown punctuation (sparser than in P. polyta or P. irrorata). The Corium (entomology), corium has sparse small yellow stains and yellow veins and is extremely branched (which gives the species its scientific name).

Pentatomidae
Pentatomidae is a family of insects belonging to the order Hemiptera, generally called shield bugs or stink bugs. Pentatomidae is the largest family in the superfamily Pentatomoidea, and contains around 900 genera and over 4700 species.Robert G. Foottit, Peter H. Adler ''Insect Biodiversity: Science and Society'', John Wiley and Sons, 2009, As hemipterans, the pentatomids have piercing sucking mouthparts, and most are phytophagous, including several species which are severe pests on agricultural crops. However, some species, particularly in the subfamily Asopinae, are predatory and may be considered beneficial. Etymology The name "Pentatomidae" is from the Greek ''pente'' meaning "five" and ''tomos'' meaning "section", and refers to the five segments of their antennae. Pentatomids are generally called "shield bugs" in British English, or "stink bugs" in American English. However, the term shield bugs is also applied broadly to include several related families (e.g. Acant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pronotum
The prothorax is the foremost of the three segments in the thorax of an insect, and bears the first pair of legs. Its principal sclerites (exoskeletal plates) are the pronotum ( dorsal), the prosternum ( ventral), and the propleuron ( lateral) on each side. The prothorax never bears wings in extant insects (except in some cases of atavism), though some fossil groups possessed wing-like projections. All adult insects possess legs on the prothorax, though in a few groups (e.g., the butterfly family Nymphalidae) the forelegs are greatly reduced. In many groups of insects, the pronotum is reduced in size, but in a few it is hypertrophied, such as in all beetles (Coleoptera). In most treehoppers (family Membracidae, order Hemiptera), the pronotum is expanded into often fantastic shapes that enhance their camouflage or mimicry. Similarly, in the Tetrigidae, the pronotum is extended backward to cover the flight wings, supplanting the function of the tegmina. See also * Glossary o ...

Scutellum (insect Anatomy)
The scutellum is the posterior portion of either the mesonotum or the metanotum of an insect thorax; however, it is used almost exclusively in the former context, as the metanotum is rather reduced in most insect groups. In the Hemiptera, and some Coleoptera, the scutellum is a small triangular plate behind the pronotum The prothorax is the foremost of the three segments in the thorax of an insect, and bears the first pair of legs. Its principal sclerites (exoskeletal plates) are the pronotum ( dorsal), the prosternum ( ventral), and the propleuron ( lateral) o ... and between the forewing bases. In Diptera and Hymenoptera the scutellum is nearly always distinct, but much smaller than (and immediately posterior to) the mesoscutum.

Corium (entomology)
The corium is the thickened, leathery, basal portion of an insect forewing or hemelytron in the order Hemiptera. Specifically the inner cell of the basal portion is the corium. Hemelytra The forewings of the winged aquatic bugs are modified into hemelytra (singular, hemelytron), in which the basal part is thickened and leathery and the apical part is membranous. The thickened region is divided into a corium and clavus. The membranous region has veins and the venation is of taxonomic importance. However, in many families, the distinction between the leathery and membranous regions of the hemelytron is not pronounced, and the wing tends to be more fully sclerotized (e.g., Pleidae) or more fully membranous (e.g., winged Gerridae The Gerridae are a family of insects in the order Hemiptera, commonly known as water striders, water skeeters, water scooters, water bugs, pond skaters, water skippers, or water skimmers.

Insects Described In 2018
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
