RESUMEN
The butterfly genus of Teinopalpus, endemic to Asia, embodies a distinct species of mountain-dwelling butterflies with specific habitat requirements. These species are rare in the wild and hold high conservation and research value. Similar to other protected species, the genetic analysis of the rare Teinopalpus aureus poses challenges due to the complexity of sampling. In this study, we successfully extracted DNA and amplified mitochondrial genomic DNA from various noninvasive sources such as larval feces, larval exuviae, larval head capsules, pupal exuviaes, and filamentous gland secretions, all integral parts of butterfly metamorphosis. This was conducted as part of a research initiative focused on the artificial conservation of T. aureus population in Jinggang Shan Nature Reserve. Our findings illustrated the successful extraction of DNA from multiple noninvasive sources, achieved through modified DNA extraction methodologies. Although the DNA concentration obtained from noninvasive samples was lower than that from muscle tissues of newly dead larvae during rearing, all samples met the requirements for PCR amplification and sequencing, yielding complete circular sequences. These sequences are pivotal for both interspecific and intraspecific genetic relationship analysis. Our methods can be extended to other insects, especially scarce species.

A new species of the genus Phengaris Doherty, 1891 (s. str.), namely Phengaris chloe sp. nov., has been discovered in Wuyi Mountain National Park, E. China. This species is markedly different from the other members in the genus Phengaris Doherty, 1891 (s. str.) and can be identified by the following characteristics: Forewing without markings in the distal of space CuA1 and CuA2, the marginal marking of underside wings weaker than other species in this genus and the distinct short protuberance at distal of valve. Photographs of adults and male genitalia are provided. A key to the Phengaris (s. str.) species based on wing pattern and male genitalia morphology is presented.
