A new hypogean species of Trechus Clairville, Trechus arrecheai sp. nov., is described from the Iberian Peninsula. It was captured by subterranean pitfall traps in a non-calcareous Superficial Subterranean Habitat from the Moncayo Massif (Zaragoza, Spain). Data on the accompanying fauna are provided and the biogeographical implications of this discovery are discussed. A synthesis of the data ab...
The first reliably identified Trechini beetle species from Baltic amber, Trechus balticus sp. n., is described. This new fossil species is most similar to extant species of the Palaearctic Trechus sensu stricto, as well as to the Nearctic Microtrechus Jeannel, 1927. Since the fossil specimen is a female and some important character states cannot be investigated, its true systematic position wit...
Giraffaphaenops yangi n. sp. is described from a limestone cave named Shizikou Dadong, Tianlin County, northwestern Guangxi, China. It is the second species of this genus, which is the most morphologically modified in the tribe Trechini in terms of troglobiomorphy. So far, Giraffaphaenops ranges in a small karstic area in northwestern Guangxi. Of the two known species, G. clarkei Deuve, 2002 wa...
External and internal thoracic structures of two carabid species (Trechini) were examined documented with different techniques. The study has a main focus on the eyeless cave-dwelling specialist Sinaphaenops wangorum, but detailed information is also provided for occurring in cave entrances. phylogenetic background structural features skeletomuscular system was addressed. morphology compared to...
Duvalius (sg. Neoduvalius) gejzadunayi sp. n. from Pećina u Dubokom potoku cave ( Donje Biševo village near Rožaje, Montenegro), the first known representative of this subgenus from the territory of Montenegro is described, illustrated and compared with the related species of the subgenus Neoduvalius Müller, 1913. This new species is characterised by depigmented, medium sized body, totally redu...
Geotrechus sarpedon sp. n., a new species of blind Trechini is described from Arbailles Massif, western Pyrenees, trance. The generic attribution of the new species was challenging as it shares morphological features of both genera Geotrechus Jeannel, 1919 and Aphaenops subgenus Hydraphaenops Jeannel, 1926, confirming their polyphyly, which has been highlighted by previous molecular studies on ...
two new species of the genus duvalius delarouzã©e from south west iran and one new perileptus schaum from south east iran are described. duvalius koeni sp. n. was collected in khuzestan and duvalius mohammadzadehi sp. n. in fars. the species are compared with d. hetschkoi matilei deuve. perileptus jelineki sp. n. was collected in baluchestan and hormozgan, and compared with other perileptus spe...
Balticeler kerneggeri gen. nov. , sp. is described based on six fossil specimens preserved in Eocene Baltic amber and imaged using light microscopy X-ray micro-computed tomography. Based certain characters observed the species it considered a “middle grade” Carabidae, outside of large family Harpalinae (as possesses scrobal seta, lack which synapomorphy that subfamily), but possessing four syna...
Beronaphaenopsgen. n.paphlagonicussp. n., a new remarkable, eyeless species of Trechini is described from Asian Turkey (type locality: cave Eşek Çukuru Mağarası 2, Milli Park Küre Dağlari, Pinarbasi District, Kastamonu Province). This specialized, troglobite species is characterized by a very peculiar combination of features, including several autapotypic features: mentum tooth large, long and ...
