In this paper, a revision of tracks referred to as Chelichnus tazelwürmi is reported. The performed analysis, consisting of a holistic approach by means of a mainly morphological analysis, and a secondarily functional one, led to the proposal of a new ichnogenus, named as Contiichnus tazelwurmi. The three dimensional morphology of the tracks allows for the inference of a complex cycle of locomotion by the trackmakers. The tracks were formed in the main phases (i.e. touch-down, weight-bearing and kick-off) by different axes of body load and transference, indicating that the whole fore autopod was involved in the cycle of locomotion and actively contacted the substrate, while for the hind autopod the functional prevalence was markedly centro-medial. Some track features suggest a therapsid-grade synapsid as potential trackmaker. However, the reconstructed autopodial structure does not correlate with known autopods from the Late Permian body fossil record. These observations stress the importance of tetrapod ichnology studies in improving knowledge in the field of vertebrate palaeontology. http://www.zoobank.org/urn:lsid:zoobank.org:pub:B4EB4D42-1A3B-48EC-B83F-6942F741AF30 http://www.zoobank.org/urn:lsid:zoobank.org:pub:B4EB4D42-1A3B-48EC-B83F-6942F741AF30 相似文献

Hedychrum zenobia sp. n. is described from Syria and Iraq, and H. linsenmaieri sp. n. from Pakistan. They belong to the H. cirtanum species group hereby established, which includes some of the largest Palaearctic Hedychrum species, characterised by a modified metascutellum projecting over the propodeum, a deep mid-tibial groove in the male and an apicomedial tooth on the third metasomal sternum in the female. Hedychrum cirtanum var. minusculum du Buysson, 1898 is transferred to the genus Hedychridium Abeille de Perrin, 1878 and elevated to species rank as Hedychridium minusculum (du Buysson, 1898) stat. n.http://www.zoobank.org/urn:lsid:zoobank.org:pub:DE7B4BF7-3E4B-4664-8F3A-1FD480F72A41 相似文献

Metaphycus parthenolecanii Japoshvili sp. n. (Hymenoptera, Chalcidoidea, Encyrtidae), a parasitoid of the European fruit lecanium Parthenolecanium corni (Bouché, 1844) (Hemiptera, Coccoidea, Coccidae) in Iran, is described and illustrated. http://www.zoobank.org/urn:lsid:zoobank.org:pub:3B846DA1-7E97-442B-B4AF-B5C727A72521 相似文献

Pomatoschistus anatoliae sp. n. is described from estuary of Göksu River on the Mediterranean coast of the Anatolia. It is distinguished from its congeners by the suborbital papilla pattern, meristic, and ecological features. DNA barcoding based on COI sequences revealed that there is a high nucleotide sequence divergence to the nearest neighbour. Kimura’s two parameter distances between P. anatoliae sp. n. and other species of Pomatoschistus and Knipowitchia have found to be at least 5.1%. http://www.zoobank.org/urn:lsid:zoobank.org:pub:4592CF50-07B5-4C25-892F-5D009057675B 相似文献
