Leptinopterus tibialis is a species of beetles belonging to the family Lucanidae.
Leptinopterus tibialis can reach a length of about 14–38 millimetres (0.55–1.50 in) in the males, about 15–18 millimetres (0.59–0.71 in) in the females. Males have well-developed mandibles, with several teeth of various sizes in the interior edges.
This quite rare species occurs in Argentina, Brazil and Paraguay.
The family Scarabaeidae, as currently defined, consists of over 35,000 species of beetles worldwide; they are often called scarabs or scarab beetles. The classification of this family has undergone significant change in recent years. Several groups formerly treated as subfamilies have been elevated to family rank, and some reduced to lower ranks. The subfamilies listed in this article are in accordance with those in Catalog of Life (2023).
Stag beetles are a family of about 1,200 species of beetles in the family Lucanidae, currently classified in four subfamilies. Some species grow to over 12 centimetres, but most to about 5 cm (2 in).
The Lucaninae comprise the largest subfamily of the stag beetles (Lucanidae).
Lucanus cervus, known as the European stag beetle, or the greater stag beetle, is one of the best-known species of stag beetle in Western Europe, and is the eponymous example of the genus. L. cervus is listed as Near Threatened by the IUCN Red List.
Dorcus titanus is a beetle of the family Lucanidae. It was described by Jean Baptiste Boisduval in 1835. Huang and Chen (2013) separated Serognathus from Dorcus by representing morphological characters and DNA analysis.
Lucanus formosanus is a stag beetle which is endemic to Taiwan, and grows to a length of 45–80 millimetres (1.8–3.1 in). Like other species in the Lucanid family, L. formosanus exhibits distinct sexual dimorphism and subsequent external morphological allometry in males. Males of the species develop mandibles of various forms depending on geographic location; i.e. northern, central, and southern morphs.
Odontolabis cuvera, the golden stag beetle, is a beetle of the family Lucanidae, stag beetles.
Chiasognathus grantii is a species of stag beetle found in Argentina and Chile. It is known as Darwin's beetle, Grant's stag beetle, or the Chilean stag beetle.
Hexarthrius parryi, the fighting giant stag beetle, is a species of large stag beetles. It belongs to the genus Hexarthrius of the tribe Lucanini. It is classified under the subfamily Lucaninae of the stag beetle family Lucanidae.
Dorcus taurus is a species of beetle belonging to the family Lucanidae which was described by Johan Christian Fabricius in 1801.
Lucanus laminifer is a species of beetles of the family Lucanidae.
Cyclommatus canaliculatus is a species of beetles belonging to the family Lucanidae.
Odontolabis dalmani is a species of beetles belonging to the family Lucanidae.
Odontolabis gazella is a species of beetle belonging to the family Lucanidae.
Odontolabis lowei is a species of beetles belonging to the family Lucanidae.
Acropyga glaesaria is an extinct species of ant in the subfamily Formicinae known from a group of possibly Miocene fossils found on Hispaniola. A. glaesaria is the first species of the ant genus Acropyga to have been described from fossils found in Dominican amber and is the one of several species of Acropyga found in the West Indies. As with other members of the genus, A. glaesaria was most likely trophobiotic.
Dorcus rectus, the little stag beetle, is a species of beetles in the family Lucanidae. It can be found in China(Liaoning), Korea, Japan, Taiwan and Russia. These beetles have a distinctive red shell that separates them from Dorcus curvidens. Males of this species have been observed to have mandible trimorphism, a characteristic that has only been described in two species of Lucanidae—with the other one being Odontolabis cuvera—"and a small number of other invertebrates" as of 2017. The mandibles are used by males as weapons.
Geodorcus servandus is a large flightless species of stag beetle in the family Lucanidae. It was discovered by P.R. Kettle in December 1960 and this holotype specimen is held in the New Zealand Arthropod Collection. It was first described by Beverley Holloway in 2007. Its type location is Mount Tuhua summit, near Lake Kaniere on the West Coast of New Zealand. The name servandus is a Latin word meaning "[something] to be preserved, conserved, looked after".
Dinonigidius bartolozzii, is a species of stag beetle endemic to Sri Lanka.
Aegus chelifer, is a species of stag beetle found in Indo-Malaya regional countries.
