Abstract
The mid-Cretaceous genus Sanaungulus from northern Myanmar is revised based on a morphology-based phylogeny of the Burmite Cantharinae by both Maximum Parsimony and Maximum Likelihood analyses. The monophyly of Sanaungulus is supported and recovered sister to Burmomiles. The generic diagnosis is redefined based on the synapomorphies, of which the characteristic antennal shape is highlighted. The aedeagus of this genus is illustrated for the first time, which is trilobite, composed of a pair of asymmetric and plate-like lateral lobes and a slender median lobe. Five new species are described under the names of S. emarginaticollis sp. nov., S. multiramus sp. nov., S. laticoxa sp. nov., S. imparitibius sp. nov. and S. ruficollis sp. nov. Two species are removed from this genus, including S. ruicheni and S. strungei due to their different antennal characters, of which the former would be placed in incertae sedis of the Burmite Cantharinae because of the inconsistent phylogenetic analyses and the latter be in an unknown genus described in another forthcoming publication. Now ten species are truly included in this genus, and a key to the species is provided. These results will provide more evidence to clarify the phylogenetic position of the Burmite cantharids in the Cantharidae.
期刊介绍:
Cretaceous Research provides a forum for the rapid publication of research on all aspects of the Cretaceous Period, including its boundaries with the Jurassic and Palaeogene. Authoritative papers reporting detailed investigations of Cretaceous stratigraphy and palaeontology, studies of regional geology, and reviews of recently published books are complemented by short communications of significant new findings.
Papers submitted to Cretaceous Research should place the research in a broad context, with emphasis placed towards our better understanding of the Cretaceous, that are therefore of interest to the diverse, international readership of the journal. Full length papers that focus solely on a local theme or area will not be accepted for publication; authors of short communications are encouraged to discuss how their findings are of relevance to the Cretaceous on a broad scale.
Research Areas include:
• Regional geology
• Stratigraphy and palaeontology
• Palaeobiology
• Palaeobiogeography
• Palaeoceanography
• Palaeoclimatology
• Evolutionary Palaeoecology
• Geochronology
• Global events.
