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.
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 Mitjaevia Dworakowska is reviewed with five new species described from China: M. acrodonta, M. bisecta, M. flexuosa, M. quinquedentata and M. tridentata spp. nov.. Detailed morphological descriptions and illustrations of these five new species and a key to all known species (males) from China are provided.
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.
The genus Singapora Mahmood is reviewed with one new species from China, Singapora shiqianensis sp. nov.. Detailed morphological description, illustration of this new species and a key to all known species (males) from China are provided.
The genus Anufrievia Dworakowska is reviewed with two new species from China: A. anchoroides sp. nov., and A. drepanoides sp. nov.. Detailed morphological descriptions and illustrations of these two new species and a key to all known species (males) from China are provided.
