The Lycini is a species-rich beetle tribe belonging to the subfamily Lycinae [1]
The Lycini is defined by the presence of the rostrum, flat, serrate to parallel-sided antennomeres 3–10, absent pronotal carinae, weak longitudinal and absent or irregular transverse costae in the elytra, tubular mesothoracic spiracles, the spoon-shaped phallobase, short parameres, a long and slender phallus, large lateral glands in the female sexual duct, short valvifers and the short spermaduct. [1]
Afrotropical, Palaearctic, Oriental, Australian (Sulawesi and Timor only), Nearctic and Neotropical (northern part only) regions. [2] [3]
A 2021 study delimited the following genera based on mito-ribosomal data. [1]
Beetles are insects that form the order Coleoptera, in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently. The largest of all families, the Curculionidae (weevils), with some 83,000 member species, belongs to this order. 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 eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops.
The Lampyridae are a family of insects in the beetle order Coleoptera with more than 2,000 described species. They are soft-bodied beetles that are commonly called fireflies, glowworms, or lightning bugs for their conspicuous use of bioluminescence during twilight to attract mates or prey. Fireflies produce a "cold light", with no infrared or ultraviolet frequencies. This chemically produced light from the lower abdomen may be yellow, green, or pale red, with wavelengths from 510 to 670 nanometers. Some species such as the dimly glowing "blue ghost" of the Eastern U.S. may seem to emit blueish-white light from a distance and in low light conditions, but their glow is bright green when observed up close. Their perceived blue tint may be due to the Purkinje effect.
Elateridae or click beetles are family of beetles. Other names include elaters, snapping beetles, spring beetles or skipjacks. This family was defined by William Elford Leach (1790–1836) in 1815. They are a cosmopolitan beetle family characterized by the unusual click mechanism they possess. There are a few other families of Elateroidea in which a few members have the same mechanism, but most elaterid subfamilies can click. A spine on the prosternum can be snapped into a corresponding notch on the mesosternum, producing a violent "click" that can bounce the beetle into the air. Clicking is mainly used to avoid predation, although it is also useful when the beetle is on its back and needs to right itself. There are about 9300 known species worldwide, and 965 valid species in North America.
The Elateroidea are a large superfamily of beetles. It contains the familiar click beetles, fireflies, and soldier beetles and their relatives.
The Lymexylidae, also known as ship-timber beetles, are a family of wood-boring beetles. Lymexylidae belong to the suborder Polyphaga and are the sole member of the superfamily Lymexyloidea.
The Rhagophthalmidae are a family of beetles within the superfamily Elateroidea. Members of this beetle family have bioluminescent organs on the larvae, and sometimes adults, and are closely related to the Phengodidae, though historically they have been often treated as a subfamily of Lampyridae, or as related to that family. Some recent evidence suggested that they were the sister group to the Phengodidae, and somewhat distantly related to Lampyridae, whose sister taxon was Cantharidae, but more reliable genome-based phylogenetics placed as the sister group to the Lampyridae.
Metriorrynchus is a genus of beetles in the family Lycidae. They occur from Australia north to northern parts of Vietnam, Laos, and Thailand, west to eastern India.
The Lycidae are a family in the beetle order Coleoptera, members of which are commonly called net-winged beetles. These beetles are cosmopolitan, being found in Nearctic, Palearctic, Neotropical, Afrotropical, Oriental, and Australian ecoregions.
Platerodrilus is a genus of beetles of the family Lycidae. They commonly appear in the literature under the name Duliticola, which is an obsolete junior synonym. The females retain a larval form as adults and are about 40–80 mm in length. The females and larvae have a flattened, dark body with large scales over the head, resembling trilobites, hence the informal names trilobite beetle, trilobite larva or Sumatran trilobite larva. In contrast, the males are much smaller, 8–9 mm, resembling other beetles. Species are found in tropical rainforests of India and South-east Asia.
Platerodrilus ruficollis is a species of trilobite beetle found in Malaysia and Singapore, also known by its junior synonym, Duliticola hoiseni.
The Omalisinae are a small subfamily of morphologically derived elaterid beetles. The Omalisinae were long considered an independent family in the deprecated family Cantharoidea, and later a family in the Elateroidea, but molecular phylogenies have demonstrated the morphological similarity of Omalisinae to other soft bodied beetles is a case of parallel evolution (homoplasy) of their soft bodies, rather than an apomorphy. Members of this beetle subfamily have been reported to have bioluminescent organs on the larvae, although no recent publications have confirmed this. Some recent evidence indicated they were the sister group to a clade comprising the families Rhagophthalmidae and Phengodidae, however a more comprehensive phylogenetic analysis based on genome sequences strongly supported the Omalisinae as being contained within the Elateridae.
Plastocerus is a genus of click beetles, the sole member of the subfamily Plastocerinae; while it has historically often been ranked as a family, the genus is now placed firmly within the family Elateridae.
The beetle genus Rhinorhipus contains a single species, Rhinorhipus tamborinensis from Queensland, Australia.
Drilini is a tribe of beetles known commonly as the false firefly beetles, in the family Elateridae.
Platerodrilus paradoxus is a species of trilobite beetle. It is only known from Sarawak.
Cautires is a genus of beetles in the family Lycidae.
Erotinae is a subfamily of net-winged beetles in the family Lycidae. There are about 10 genera and 19 described species in Erotinae.
The Pyrophorini are a New World taxonomic tribe within the Elateridae subfamily Agrypninae. Pyrophorini is a tribe of bioluminescent beetles, and includes such genera as Pyrophorus and Ignelater.
Sinopyrophorus is a genus of bioluminescent hard-bodied clicking beetles in the superfamily Elateroidea, and is the sole member of the recently recognized family Sinopyrophoridae. The genus currently contains a single species, Sinopyrophorus schimmeli, which was described in 2019 from the subtropical evergreen broadleaf forests of western Yunnan, China.
Burmese amber is fossil resin dating to the early Late Cretaceous Cenomanian age recovered from deposits in the Hukawng Valley of northern Myanmar. It is known for being one of the most diverse Cretaceous age amber paleobiotas, containing rich arthropod fossils, along with uncommon vertebrate fossils and even rare marine inclusions. A mostly complete list of all taxa described up until 2018 can be found in Ross 2018; its supplement Ross 2019b covers most of 2019.
