Pseudothryptus
''Pseudothryptus multiseriatus'' is the only species of ''Pseudothryptus'', a genus of minute marsh-loving beetle in the subfamily Limnichinae. Initially described in 1923 as part of the large genus ''Caccothryptus'', it was redescribed in 2004 due to a number of physical differences with other Limnichidae, especially in its genitalia. Taxonomy ''Pseudothryptus multiseriatus'' is the only species in the genus ''Pseudothryptus''; a genus of Limnichinae, a subfamily of the minute marsh-loving beetles (Limnichidae). Within Limnichinae it belongs to the "Mandersia group" of genera, alongside the large genus ''Caccothryptus'' and four other small genera— Euthryptus, Mandersia, Resachus, and Simplocarina. These genera share a number of physical features, such as a non-articulated aedeagus (male reproductive organ) without an articulated internal piece ("spiculum") within the median lobe; this distinguishes the genera from the genus '' Byrrhinus''. The Afrotropical genera '' T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caccothryptus Testudo
''Caccothryptus'' is a genus of minute marsh-loving beetles in the subfamily Limnichinae. The genus was formally established (circumscribed) by the entomologist David Sharp in 1902, with '' C. compactus'' as the type species. In 2014, the entomologists Carles Hernando and Ignacio Ribera published a major revision of the genus, reorganizing it from seven species into twenty species in five species groups, classified mainly by similarities in genital shape. Discoveries in the following years have brought the total number of species up to thirty-four. Due to the relative lack of studies and material on Asian Limnichidae, more species are likely still to be described. Ranging from 2.5 to 5.5 mm in total length, the beetles have ovoid bodies ranging from black to brown in color. Their range extends across Southeast Asia, alongside portions of East Asia and South Asia. They generally live in water-logged dead wood adjacent to small streams.

Limnichidae
Limnichidae, commonly called minute marsh-loving beetles, is a family of beetles belonging to Byrrhoidea. There are at least 30 genera and 350 described species in Limnichidae. They are found worldwide, with the greatest diversity in tropical regions. Most species seem to be associated with water-adjacent habitats, such as riparian and coastal locations, though many species are likely fully terrestrial, with some species being associated with leaf litter and arboreal habitats. Species with known diets feed on moss or algae. The oldest fossils of the family are known from mid-Cretaceous Burmese amber from Myanmar.

Beetles Of Asia
Beetles are insects that form the Taxonomic rank, order Coleoptera (), in the superorder Holometabola. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described arthropods and 25% of all known animal species; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. However, the number of beetle species is challenged by the number of species in Fly, dipterans (flies) and hymenopterans (wasps). Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ...

Byrrhoidea Genera
Byrrhoidea is a superfamily of beetles belonging to Elateriformia that includes several families which are either aquatic or associated with a semi-aquatic habitat. Other than the superfamily Hydrophiloidea, most of the remaining Polyphagan beetles which are aquatic are in this superfamily. Description Adults of many Byrrhoidea have exocone eyes (with expanded corneal lens). The anterior edge of the scutellar shield is often abruptly elevated (except in Psephenidae and Cneoglossidae). A variety of byrrhoids have the first three abdominal ventrites solidly fused together. Larvae of most Limnichidae have one pair of anal hooks on the tenth abdominal segment, while Cneoglossidae and Ptilodactylidae have three or more hooks on each side of this segment. Larvae of Lutrochidae and Elmidae, as well as the limnichid genus ''Hyphalus'', have anal gill tufts. Almost all byrrhoid larvae have anterior abdominal spiracles that are biforous (or bilabiate) in shape. The degree of wing d ...

Phallus
A phallus (: phalli or phalluses) is a penis (especially when erect), an object that resembles a penis, or a mimetic image of an erect penis. In art history, a figure with an erect penis is described as ''ithyphallic''. Any object that symbolically—or, more precisely, iconically—resembles a penis may also be referred to as a phallus; however, such objects are more often referred to as being phallic (as in "phallic symbol"). Such symbols often represent fertility and cultural implications that are associated with the male sexual organ, as well as the male orgasm. Etymology The term is a loanword from Latin ''phallus'', itself borrowed from Greek (''phallos''), which is ultimately a derivation from the Proto-Indo-European root *''bʰel''- "to inflate, swell". Compare with Old Norse (and modern Icelandic) ''boli'', "bull", Old English ''bulluc'', "bullock", Greek , "whale".

Parameres
Parameres ('side parts') are part of the external reproductive organs of male insects and the term was first used by Verhoeff in 1893 for the lateral genital lobes in Coleoptera. The primary phallic lobes which appear in the nymph or larval stages may become a pair of penes in the Ephemeroptera or a simple median penis in the Thysanura. In higher insect orders from Orthoptera to Hymenoptera, each of the primary lobes is divided into two secondary lobes or phallomeres, termed parameres and mesomeres (NB: this use of the term "mesomere" is not to be confused with the same term in segmentation embryology.) In adult insects parameres may elongate and become genital claspers. These claspers may themselves occur in two segments, forming a proximal basimere and a distal telomere A telomere (; ) is a region of repetitive nucleotide sequences associated with specialized proteins at the ends of linear chromosomes (see #Sequences, Sequences). Telomeres are a widespread genetic featu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elytra
An elytron (; ; : elytra, ) is a modified, hardened forewing of beetles (Coleoptera), though a few of the true bugs (Hemiptera) such as the family Schizopteridae are extremely similar; in true bugs, the forewings are called hemelytra (sometimes alternatively spelled as "hemielytra"), and in most species only the basal half is thickened while the apex is membranous, but when they are entirely thickened the condition is referred to as "coleopteroid". An elytron is sometimes also referred to as a shard. Description The elytra primarily serve as protective wing-cases for the hindwings underneath, which are used for flying. To fly, a beetle typically opens the elytra and then extends the hindwings, flying while still holding the elytra open, though many beetles in the families Scarabaeidae and Buprestidae can fly with the elytra closed (e.g., most Cetoniinae; ). In a number of groups, the elytra are reduced to various degrees, (e.g., the beetle families Staphylinidae and Ripipho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Setae
In biology, setae (; seta ; ) are any of a number of different bristle- or hair-like structures on living organisms. Animal setae Protostomes Depending partly on their form and function, protostome setae may be called macrotrichia, chaetae, scales, or informally, hairs. The setal membrane is not cuticularized, so movement is possible. Annelid setae are stiff bristles present on the body. They allow earthworms and their relatives to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground. Setae in oligochaetes (the group including earthworms) are largely composed of chitin. They are classified according to the limb to which they are attached; for instance, notosetae are attached to notopodia; neurosetae to neuropodia. The setae on polychaete worms are referred to as chaeta due to their differing morphology. Crustaceans have mechano- and chemosensory setae. Setae are especially pres ...
