Phylogenetic Relationships of Japanese Auritibicen Species (Hemiptera: Cicadidae: Cryptotympanini) Inferred from Mitochondrial and Nuclear Gene Sequences

We investigated the phylogenetic relationships and divergence times within the genus Auritibicen(Cicadidae: Cicadinae: Cryptotympanini), analyzing five Japanese species (A. japonicus, A. bihamatus,A. kyushyuensis, A. esakii and A. flammatus) and three species from East Asian mainland and Taiwan (A. atrofasciatus, A. intermedius and A. chujoi) using mitochondrial cytochrome oxidase subunit I (COI) and nuclear elongation factor 1-alpha (EF-1a) gene sequences. Although the EF-1a gene tree did not resolve the relationships among these Auritibicen species, the trees based on COI gene and the combined data set showed that Japanese taxa comprised three distinct lineages: the individual species A. flammatus and A. bihamatus, and the A. japonicus group, comprising A. japonicus, A. esakii and A. kyushyuensis from Japan and A. intermedius from Korea. In A. kyushyuensis, which comprises three populations in Kyushu, western Honshu and Shikoku, the specimens from western Honshu and Shikoku were closely related to each other, but not to the specimen from Kyushu; instead, they were sister to the Korean A. intermedius. The incongruence between the gene tree and species tree necessitates further population genetic and morphological studies to confirm the classification and species status of the western Honshu and Shikoku populations of A. kyushyuensis, which were originally described as two independent species. Divergence time estimation suggested that the most recent common ancestor of Auritibicen species studied dated back to the late Pliocene and that the species of the A. japonicus group diverged during the mid Pleistocene. Thus, the Pleistocene climatic fluctuation may have promoted the divergence of the Auritibicen species.

Description of a new genus and species of the tribe Dundubiini (Hemiptera: Cicadidae: Cicadinae) from India, with taxonomic notes on Dundubiini including the description of two new subtribes

ABSTRACT A new cicada genus and species, Zaphsa princeps n. gen., n. sp., is described from India. Four subtribes, Dundubiina Atkinson, 1886, Megapomponiina Lee n. subtr., Orientopsaltriina Lee n. subtr., and Aolina Boulard, 2012, are placed in Dudubiini Atkinson, 1886 of the subfamily Cicadinae Latreille, 1802. The new genus Zaphsa n. gen. is placed in Aolina. Mata Distant, 1906 is transferred to Oncotympanina Ishihara, 1961.

Descriptions of four new species of Semia Matsumura (Hemiptera: Cicadidae: Psithyristriini) from Vietnam, with a key to the species of Semia

This paper provides descriptions of four new species of the genus Semia Matsumura, 1917 from Vietnam: Semia magna sp. nov., Semia spiritus sp. nov., Semia pallida sp. nov., and Semia albusequi sp. nov. A key to the 13 species of Semia is provided.

Erection of a new genus Biura gen. nov., of the subtribe Aolina (Hemiptera: Cicadidae: Cicadinae: Dundubiini)

A new genus, Biura gen. nov., is erected within the subtribe Aolina Boulard, 2012, designating Haphsa bicolora Sanborn, 2009 as the type species. This new genus is distinguished from all other genera in Aolina by the light-colored body lacking prominent markings, non-infuscated wings, very small and short male operculum, thin and long uncal lobes, and distinctly prominent basal lobes of the pygofer.
