To explore the characteristics of mitogenomes and discuss the phylogenetic relationships and molecular evolution of the six tribes within Typhlocybinae, 11 complete mitogenomes are newly sequenced and comparatively analyzed. In all of these complete mitogenomes, the number and order of the genes are highly conserved in overall organization. The PCGs initiate with ATN/TTG/GTG and terminate with TAA/TAG/T. Almost all tRNAs are folded into the typical clover-leaf secondary structure. The control region is always variable in length and in numbers of multiple tandem repeat units. The atp8 and nad2 exhibits the highest evolution rate among all the PCGs. Phylogenetic analyses based on whole mitogenome sequences, with three different datasets, using both maximum likelihood and Bayesian methods, indicate the monophyly of Typhlocybinae and its inner tribes, respectively, except for Typhlocybini and Zyginellini that are paraphyletic. Finally, we confirm that Erythroneurini is a subtribe of Dikraneurini.
General characteristics of Anufrievia Dworakowska and a key to the species from China and Thailand are provided. Twenty-one new species, Anufrievia adaucta, A. arcuata, A. curva, A. expensa, A. falcata, A. forcipiformis, A. fusina, A. jinghongensis, A. liubanus, A. parisakazu, A. plana, A. qinlingensis, A. quadrata, A. sphenoides, A. subapicifixa, A. subdentata, A. sufflata, A. symmetrica, A. triangulata, A. triprocessa and A. wolongensis are described. Four species are newly recorded from China: A. akazu (Matsumura), A. badjawae Dworakowska, A. bauhinicola Dworakowska & Viraktamath and A. zelta Dworakowska. A. badjawae is also a new record to Thailand.
Five new species and two new records of Erythroneurini are reported from China. The five new species, Dentaneura biangulata, Motaga rokfaoides, Seriana paraequata, Shibinga graciliprocessa and S. grossiprocessa spp. nov. are described and illustrated. Two new records from China, Alnetoidia pavo Dworakowska, 1994 and Empoascanara angkhangica, Hongsaprug, 1983, are also illustrated.
The genus Salka Dworakowska is reviewed with seven new species described from China: S. aequilonga, S. delphiura, S. dipteriga, S. lamellipenia, S. limboserrata, S. longipenia and S. taopenna spp. nov. Detailed morphological descriptions and illustrations of these seven new species and a key to all known species (males) from China are provided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
