The monotypic genus Damora (Nymphalidae, Heliconiinae) contains a single species, Damora sagana, which is widely distributed across southern China. Herein, its complete mitogenome was sequenced to further understand lepidopteran mitogenome characteristics, reconstruct the nymphalid family phylogeny, and infer the subdivision of Heliconiinae species. The circular mitogenome was 15,151 bp long, abundant in A and T, and comprised of 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, 2 ribosomal RNA (rRNA) genes, and one control region with a gene arrangement typical of lepidopteran mitogenomes. ATN codons initiated all PCGs, except cytochrome c oxidase subunit 1 (COX1), which was initiated by a CGA sequence as has been observed in other lepidopterans. Three PCGs (COX1, COX2 and ND4) employed a single T termination signal, whereas others had the typical complete termination codon (TAA). All tRNA genes were folded into the typical cloverleaf structure except for tRNA-Ser (AGN). The A+T-rich region included the conserved motif ‘ATAGA’ followed by a 17 bp poly-T stretch, which was also observed in tribe Argynnini mitogenomes. A phylogenetic tree was constructed via multiple methods using the 13 PCGs data of D. sagana and other available mitogenomes of nymphalid species. All three phylogenetic trees yielded the same topology. These results were consistent with those from previous studies of most major nymphalid groups, except those regarding tribe subdivision in certain subfamilies such as Argynnini + (Acraeini + Heliconiini) for Heliconiine. Furthermore, our analyses identified that the genus Cethosia was grouped with the genus Acraea composing the tribe Acraeini with strong support.

Vanessa indica is a small butterfly lacking historical molecular and biological research. Vanessa indica belongs to the family Nymphalidae (Lepidoptera: Papilionoidea), which is the largest group of butterflies and are nearly ubiquitous. However, after more than a century of taxonomic and molecular studies, there is no consensus for family classification, and the phylogenetic relationships within Nymphalidae are controversial. The first objective was to sequence and characterize the complete mitochondrial genome of V. indica. The most important objective was to completely reconstruct the phylogenetic relationships for family members within Nymphalidae. The mitochondrial genomic DNA (mtDNA) of V. indica was extracted and amplified by polymerase chain reaction. The complete mitochondrial sequence was annotated and characterized by analyzing sequences with SeqMan program. The phylogenetic analyses were conducted on thirteen protein coding genes (PCGs) in 95 mtDNA of Nymphalidae downloaded from GenBank for reference using the maximum likelihood method and Bayesian inference to ensure the validity of the results. The complete mitogenome was a circular molecule with 15,191 bp consisting of 13 protein coding genes, two ribosomal RNA genes (16S rRNA and 12S rRNA), 22 transfer RNA (tRNA) genes, and an A + T-rich region (D-loop). The nucleotide composition of the genome was highly biased for A + T content, which accounts for 80.0% of the nucleotides. All the tRNAs have putative secondary structures that are characteristic of mitochondrial tRNAs, except tRNASer(AGN). All the PCGs started with ATN codons, except cytochrome c oxidase subunit 1 (COX1), which was found to start with an unusual CGA codon. Four genes were observed to have unusual codons: COX1 terminated with atypical TT and the other three genes terminated with a single T. The A + T rich region of 327 bp consisted of repetitive sequences, including a ATAGA motif, a 19-bp poly-T stretch, and two microsatellite-like regions (TA)8. The phylogenetic analyses consistently placed Biblidinae as a sister cluster to Heliconiinae and Calinaginae as a sister clade to Satyrinae. Moreover, the phylogenetic tree identified Libytheinae as a monophyletic group within Nymphalidae. The complete mitogenome of V. indica was 15,191 bp with mitochondrial characterizations common for lepidopteran species, which enriched the mitochondria data of Nymphalid species. And the phylogenetic analysis revealed different classifications and relationships than those previously described. Our results are significant because they would be useful in further understanding of the evolutionary biology of Nymphalidae.

The sensilla type, number and distribution in male and female adults of Carabus elysii Thomson, 1856 (Coleoptera: Carabidae) were studied using scanning electron microscopy. The results showed that there are seven categories and 12 types of sensilla in C. elysii adults: three types of S.Ch, three types of S.T, two types of S.B and one each of B.B, S.Co, S.Ca and S.Cam. There is no difference between male and female in the types of sensilla. Apart from the significant difference in the number and distribution of S.B.2, S.Co and S.Ca between male dorsal and ventral surfaces, there are no significant differences between male and female antennae. In general, the number of sensilla in females is larger than that in males. The results provide a basic reference for future ultrastructure, electrophysiological, and comparative behavioral studies of Carabus species.

This study carries out in-depth political feasibility analysis of the prospective health financingreform currently taking place in Taiwan. The National Health Insurance (NHI) Program, whichwas established in Taiwan in 1995, covers virtually all of the island’s citizens. Between the years2001 and 2004, the Taiwanese Government organized a taskforce to carry out the wholesale reformof the NHI program into the so-called ‘Second Generation NHI Program’. This study is part of thecomprehensive review, focusing on the preferences and positions of key policy stakeholders withregard to the financial reform proposals, as well as their network relationships. The approach ofstakeholder analysis was employed to conduct this empirical study. The results reveal that the newfinancing scheme has a certain degree of support from the policy stakeholders participating in thisstudy, and that in particular, the measures concerning equity and sustainability were most welcome. However, controversy remains with regard to the issue of the equitable sharing of contributions. It is clear that there is much strong support for the new scheme amongst the administrativeand legislative elite, although the same level of support is not evident amongst the social eliteaffiliated with employees’ associations and welfare groups.
