Saussurea taquetii reported from Jejudo Island is either treated as a synonym of S. japonica or is recognized as a distinct taxon. Saussurea japonica and S. pulchella belong to the sect. Theodorea by having peculiar outer phyllaries with pale purplish scarious apical appendages; they are closely related to each other morphologically and are known to occur widely throughout the Korean Peninsula. To assess the taxonomic status of S. taquetii, we investigated representative populations of S. taquetii from jejudo Island, Korea, and S. japonica from Kyushu in Japan. We conducted a comparative study morphologically using specimens of three species from KH, CNU, and TI. Saussurea taquetii is very similar morphologically and ecologically to S. japonica in Kyushu. Unlike previous floristic treatments, we concluded that the two taxa, S. pulchella and S. taquetii, occur on the Korean Peninsula and on jejudo Island, respectively.

Abstract Freshwater mussels belonging to the genus Nodularia (Family Unionidae) are known to be widely distributed in East Asia. Although phylogenetic and population genetic studies have been performed for these species, there still remain unresolved questions in their taxonomic status and biogeographic distribution pathways. Here, the nucleotide sequences of CO1 and 16S rRNA were newly determined from 86 N. douglasiae and 83 N. breviconcha individuals collected on the Korean Peninsula. Based on these data, we revealed the following results: (1) N. douglasiae can be divided into the three genetic clades of A (only found in Korean Peninsula), B (widely distributed in East Asia), and C (only found in the west of China and Russia), (2) the clade A is not an independent species but a concrete member of N. douglasiae given the lack of genetic differences between the clades A and B, and (3) N. breviconcha is not a subspecies of N. douglasiae but an independent species apart from N. douglasiae. In addition, we suggested the plausible scenarios of biogeographic distribution events and demographic history of Nodularia species.

This study reassesses the taxonomic status of Neotropical blue and purple/rose-colored Cithaerias butterflies, thus complementing a previous study of the rose-colored species. Based on comparative study of wing coloration and genitalia morphology, I revise species definitions and the taxonomic status of: Cithaerias andromeda, C. azurina STAT. REV., C. esmeralda STAT. REV., C. bandusia STAT. REV., C. pyropina, and C. songoana STAT. REV. Photographs of adults and illustrations of male and female genitalia are provided for all species. Of particular importance are the genitalia illustrations of male and female C. azurina, presented here for the first time, as well as finding a putative first female of Ecuadorean subspecies C. pyropina julia.

This article describes the results of a comparative study of some monuments (settlement, dolmen, rock art) and some artifacts (pottery, arrowhead, dagger, bronze mirror, bead, whetstone) of the Bronze and Early Iron Ages of Mongolian steppe and Korean Peninsula. The comparative study sought to clarify the external and internal structures of the monuments, as well as the burial practices. In the case of artifacts, their materials and functions were considered.

A comparative study was done in Spain of canker and withering of branches in almond and peach trees. Similar diseases of these fruit trees, described by several authors and attributed to Fusicoccum amygdali and Phomopsis amygdalina, suggests that these fungi are identical. Spanish isolates produced phialidic conidiogenous cells and occasionally β-conidia typical of the genus Phomopsis. A study of the type specimen of F. amygdali reveals that it also belongs in Phomopsis. Phomopsis amygdali (Del.) Tuset & Portilla comb.nov. is proposed to accommodate the fungus; Phomopsis amygdalina Canonaco is reduced to synonymy with it.
