Guiaphaenops deuvei: A new species of cave-dwelling Ground Beetle from Guangxi Province.

Ground Beetles (Carabidae) are large, usually carnivorous Beetles, abundant across much of the globe. They are able to defend themselves by secreting noxious or caustic chemicals from glands on their abdomens (Bombardier Beetles are Carabids). Members of the genus Guiaphaenops specialist cave-dwellers known only from the limestone caves of Lingyun County in northwestern Guangxi Province, China. They show specialisations to cave life found in many animal groups, including the loss of their eyes and pigment.

In a paper published in the journal ZooKeys on 20 April 2017, Bin Feng of the Forestry Department of Guangxi Zhuang Autonomous Region and the Department of Entomology at South China Agricultural University, Guofu Wei of the Administrative Bureau of Huangjiang World Natural Heritage and Mingyi Tian, also of the Department of Entomology at South China Agricultural University, describe a new species of Guiaphaenops from a limestone cave near Yangli in Lingyun County.

The new species is named Guiaphaenops deuvei, in hnour of French entomologist Thierry Deuve of the National Museum of Natural History in Paris (who first described the genus Guiaphaenops) for his work on the Ground Beetles of China. The species is described from a single male specimen found on the floor of the cave. It is 7 mm in length, and yellowish in colour.

Six new species of Ground Beetles from South Vietnam.

Ground Beetles (Carabidae) are large, usually carnivorous Beetles, abundant across much of the globe. They are able to defend themselves by secreting noxious or caustic chemicals from glands on their abdomens (Bombardier Beetles are Carabids). Larger species are often unable to fly. Ground Beetles have a fossil record dating back to the Triassic; there are around 40 000 described extant species.

In a paper published in the journal ZooKeys on 26 November 2012, Dmitri Fedorenko of the A. N. Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences describes six new species of Carabid Beetles from Vietnam. All the new species are placed in the genus Taridius, which is widespread in South and Southeast Asia.

The first new species is named Taridius ornatus, which means ‘ornate’, though no explanation of any of the species names used in the paper is provided. Taridius ornatus is an elongate, slightly flattened 7.4-8.4 mm brown Beetle with mottled black markings on its dorsal (upper) surface. The species is described from seven male and four female specimens collected on the Dalat Plateau in Lam Dong and Dak Lak Provinces in South Vietnam, at altitudes of between 1400 and 1900 m.

The second new species is named Taridius piceus. It is an 8.5-9.6 mm flattened, elongate, wingless, light brown Beetle with black markings on its dorsal surface. The species is described from four male and four female specimens collected from a single location in the Nui Ba Nature Reserve in Lam Dong Province in South Vietnam, at an altitude of 1700-1900 m on the north slope of Bi Doup Mountain.

The third new species is named Taridius fasciatus. This is an elongate, subconvex, light brown Beetle with a black pattern on its dorsal surface. The species is described from 20 male and 20 female specimens collected in the Bu Gia Map National Park in Binh Phuoc Province at an altitude of 540 m, plus one female collected in Dak Lak Province about 75 km north of Phan Tiet at an altitude of 1100 m and one male specimen collected in the Kiwlomm Pass in Mae Hong Son Province, Thailand, at an altitude of about 1400 m.

Ground Beetles (Carabidae) are large carnivorous Beetles with destictive black or metalic elytra (wing-cases) that are sometimes fused, preventing flying. They have paired glands on their lower abdomens which produce noxious chemicals, used to defend the Beetles against predators (in one group of Carabids, the Bombadier Beetles,these secretions have evolved to react violently, even explosively, to one-another). The group has a fossil record dating back to the Triassic.

A new species of Ground Beetle from Papua New Guinea.

Ground Beetles (Carabidae) are large carnivorous Beetles with destictive black or metalic elytra (wing-cases) that are sometimes fused, preventing flying. They have paired glands on their lower abdomens which produce noxious chemicals, used to defend the Beetles against predators (in one group of Carabids, the Bombadier Beetles,these secretions have evolved to react violently, even explosively, to one-another). The group has a fossil record dating back to the Triassic.

In a paper published in the journal ZooKeys on 29 November 2012, Kipling Will of the Essig Museum of Entomology at the University of California, Berkeley and David Kavanaugh of the Department of Entomology at the California Academy of Sciences describe a new species of Carabid Beetle from the Finisterre Mountain Range on the northeastern coast of Papua New Guinea.

The new species is placed in the genus Lesticus and given the specific name finisterrae, meaning ‘from Finisterre’. The species is described from a single male specimen collected near Teptep on the borders between Madang and Morobe Provinces in a pitfall trap in montane moss forest at an altitude of 3050 m. The area was at the upper limit of the forest’s distribution, being replaced by open grassland slightly higher. The single specimen is a dark brown Beetle, 20 mm in length, with sharply hooked mandibles.

A new species of cave-dwelling Ground Beetle from Jiangxi Province, southeast China.

Ground Beetles (Carabidae) are large, usually carnivorous Beetles, abundant across much of the globe. They are able to defend themselves by secreting noxious or caustic chemicals from glands on their abdomens (Bombardier Beetles are Carabids). Larger species are often unable to fly. Ground Beetles have a fossil record dating back to the Triassic; there are around 40 000 described extant species.
In a paper published in the journal ZooKeys on 19 February 2014, Jianmei Pang and  Mingyi Tian of the Department of Entomology at the College of Natural Resources and Environment at South China Agricultural University, describe a new species of Ground Beetle from the  Zhushan Dong II limestone cave in Wanzhai County, Jiangxi Province, China.

The new species is placed in the genus Morimotoidius, and given the specific name zhushandong, which derives directly from the name of the cave where it was discovered. Morimotoidius zhushandong is a slender, elongate Ground Beetle reaching 11.5-12.5 mm in length. It apparently lives only bellow ground, but unlike many trogloditic (cave dwelling) species, it retains a dark brown pigmentation and functional eyes.

A new species of Ground Beetle from Mexico.

Ground Beetles (Carabidae) are large, usually carnivorous Beetles, abundant across much of the globe. They are able to defend themselves by secreting noxious or caustic chemicals from glands on their abdomens (Bombardier Beetles are Carabids). Larger species are often unable to fly. Ground Beetles have a fossil record dating back to the Triassic; there are around 40 000 described extant species.

In a paper published in the journal ZooKeys on 4 July 2013, George Ball and Danny Shpeley of the Department of Biological Sciences at the University of Alberta describe a new species of Ground Beetle from Oaxaca State in Mexico, as part of a wider study into Ground Beetles in the Americas.

The new species is placed in the genus Coarazuphium and given the specific name whiteheadi, in honour of Donald Whitehead, deceased, who collected some of the specimens from which the species is described. Coarazuphium whiteheadi is described from two female and one male specimens from cloud forest remnants at high altitudes western Oaxaca. It is a small Ground Beetle, 4.13-4.40 mm in length, yellow-white in colour, with an elongate oval body.

A blind, cave dwelling, Ground Beetle from Anatolian Turkey.

Ground Beetles, Carabidae, are large, usually carnivorous Beetles, abundant across much of the globe. They are able to defend themselves by secreting noxious or caustic chemicals from glands on their abdomens (Bombardier Beetles are Carabids). Larger species are often unable to fly. Ground Beetles have a fossil record dating back to the Triassic; there are around 40 000 described extant species.

In a paper published in the journal ZooKeys on 27 December 2012, Borislav Guéorguiev of the National Museum of Natural History in Sofia, Bulgaria, describes a new species of blind, cave dwelling Ground Beetle from northern Anatolia.

The new species is given the name Beronaphaenops paphlagonicus, where 'Beronaphaenops' means 'Beron's without eyes', in honour of Petar Beron, a Bulgarian biologist noted for his studies of cave-dwelling invertebrates, and 'paphlagonicus' refers to Paphlagonia, an ancient name for the central Black Sea coast of Anatolia.

Two new species of Ground Beetle from the Pyrenees.

Ground Beetles (Carabidae) are large carnivorous Beetles with destictive black or metalic elytra (wing-cases) that are sometimes fused, preventing flying. They have paired glands on their lower abdomens which produce noxious chemicals, used to defend the Beetles against predators (in one group of Carabids, the Bombadier Beetles,these secretions have evolved to react violently, even explosively, to one-another). The group has a fossil record dating back to the Triassic.

In a paper published in the journal ZooKeys on 28 August 2012, Arnaud Faille of the Zoologische Staatssammlung München, Charles Bourdeau of Rebigue in France and Javier Fresneda of the Museu de Ciències Naturals (Zoologia) in Barcelona describe two new species of Carabid Beetles from the Pyranees Mountains, on the border between France and Spain. Both new species are placed in the widespreas Eurasian genus Trechus.

The first new species described is named Trechus bouilloni, named in honour of Michel Bouillon, a caver who discovered Ground Beetle populations in the Pyranees. It is an elongate, round-sided, dark-brown Beetle, roughly 5 mm in length, found living on a scree slope beneath a limstone cliff on the northern slope of the plateau of the Sierra de Andía–Urbasa in the Navarra Region of Spain, on the south side of the Pyranees.

The second new species described is named Trechus bruckoides, which implies a relationship with Trechus brucki, the new Beetle being a cryptic species formerly identified as members of that species, and identified by DNA analysis of museum specimens. Trechus bruckoides is an elongated, round-sided, dark-brown Beetle, similar in appearance to Trechus brucki. The species is known from a single species living in sinkholes on the limestone Esturou Platuae, in the Pyrénées Atlantiques department of France.
