The complete mitochondrial genome of Chibiraga houshuaii (Lepidoptera, Limacodidae) and its phylogenetic implications.

Chibiraga is a mall East Asian genus in the family Limacodidae (slug-moths). The latter includes many agricultural pests. Mitochondrial genome analysis is an important tool for studying insect molecular identification and phylogenetics. However, there are very few mitogenome sequences available for Limacodidae species, and none for the genus Chibiraga at all. To explore the mitogenome features of Chibiraga and verify its phylogenetic position, the complete mitogenome of Chibiraga houshuaii was sequenced and annotated. The complete 15,487 bp genome encoded 37 mitochondrial genes, including 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a control region (CR). Most of the PCGs had typical ATN start codons and terminated with TAA or a single T residue. UUA (Leu2), AUU (Ile), UUU (Phe), AUA (Met) and AAU (Asn) were the five most frequently used codons. All tRNAs were folded into cloverleaf secondary structure, except for trnS1, which lacked the DHU arm. Phylogenetic analyses within the superfamily Zygaenoidea were performed based on multiple datasets from mitochondrial genes. The results showed that the families Phaudidae, Limacodidae and Zygaenidae were respectively recovered as monophyly; C. houshuaii was clustered in a clade with nettle type larvae in Limacodidae.

The complete mitochondrial genome of Meleonoma mirabilis (Wang 2003) (Lepidoptera: Autostichidae).

The mitogenome of Meleonoma mirabilis was determined in this study. It was 15,268 bps long and strongly AT biased. It harbored 13 PCGs, 22 tRNAs, 2 rRNAs, and 1 non-coding control region (334 bps). BI phylogenetic analysis based on 13 concatenated PCGs from 24 moth species indicated that M. mirabilis was clustered in the family Autostichidae, which was consistent with the latest phylogenetic study.

The complete mitochondrial genome of Periacma orthiodes Meyrick, 1894 (Lepidoptera: Autostichidae).

The complete mitogenome of Periacma orthiodes Meyrick, 1894 was determined in this study. It was 15,306 bps long and strongly AT biased. It consisted of 13 PCGs, 22 tRNAs, 2 rRNAs and 1 non-coding control region (371 bps). Most PCGs used the typical ATN start codon, except for cox1. Four genes (cox1, cox2, nad4 and nad5) used truncated stop codons (a single T or TA) rather than the commonly used TAA or TAG. All tRNAs, excluding TrnS1, folded into the iconic cloverleaf structure. ML phylogenetic tree built on 13 PCGs from P. orthiodes and another 28 species in Gelechioidea demonstrated that the genus Periacma was a member of the family Autostichidae, which was consistent with the newest phylogenetic study.

The complete mitochondrial genome of Ripeacma umbellata Wang, 2009 (Lepidoptera: Autostichidae).

The mitogenome of Ripeacma umbellata Wang, 2009 was reported in this study. It was 15,486 bps long and strongly AT biased, consisting of 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), 2 ribosomal RNAs (rRNAs), and 1 non-coding control region (351 bp). Most PCGs used the conventional ATN start codon, except for cox1 and cox2. Four genes used single T residue as stop codon rather than the routinely used TAA or TAG. All tRNAs, except for TrnS1, could fold into the cloverleaf secondary structure. Bayesian inference phylogenetic tree built on 13 PCGs from R. umbellata and another 21 species in Gelechioidea demonstrated that genus Ripeacma was a member in Autostichidae, which was consistent with the latest phylogenetic study.

One new species and one newly recorded species of the genus Lasiochira Meyrick, 1931 (Lepidoptera, Oecophoridae) from China.

Lasiochira wuzhishanensis Yin, sp. nov. is described herein from the island province of Hainan, China. It is diagnosed from a similar species, Lasiochira jianfengensis Yin, Wang & Park, 2014. Both species are sympatric in Hainan province, but the latter is also known in northern Vietnam. Lasiochira pallidiptera Yin, Wang & Park, 2014 is recorded for the first time from China. Color images of the adults and genitalia of the above three species are provided. In addition, a checklist and a geographical distribution map of all species of Lasiochira Meyrick are included.

Three new species of Meleonoma Meyrick from Yunnan, China (Lepidoptera, Gelechioidea, Xyloryctidae).

Three new species of Meleonoma Meyrick, 1914 (Gelechioidea, Xyloryctidae) from China, Yunnan Province, Meleonoma plicata sp. nov., M. scalprata sp. nov. and M. taeniata sp. nov., are described and illustrated. A key to Meleonoma species known from China is provided.

Two new species of the genus Meleonoma Meyrick from China (Lepidoptera, Gelechioidea, Xyloryctidae).

Two new species of Meleonoma Meyrick, 1914a (Gelechioidea, Xyloryctidae) from southeastern China are described: Meleonoma foliiformis Yin, sp. nov. from Guangxi Province and M. projecta Yin, sp. nov. from Fujian Province. Adults and male genitalia are described in detail. A list of the Meleonoma species occurring in China is given. The taxonomic position of Meleonoma has been unstable, and under debate. Nonetheless, it is here tentatively placed in the family Xyloryctidae, following the latest molecular phylogenetic study concerning this genus.

Taxonomic study of the genus Meleonoma Meyrick from Thailand (Lepidoptera, Gelechioidea).

Five species of the genus Meleonoma Meyrick are reported from Thailand. Meleonoma triangula Wang, sp. n., Meleonoma dorsolobulata Wang, sp. n., Meleonoma elongata Wang, sp. n., and Meleonoma bilobata Wang, sp. n. are described as new; Meleonoma facialis Li & Wang, 2002 is redescribed and recorded for the first time from Thailand.
