Stathmopodidae, in the superfamily Gelechioidea, was first described by Edward Meyrick in 1913. This family has various characteristics, such as feeding on crops, moss, spores of fern, aphids, etc., but there is a lot of difficulty in identification due to morphological similarities between species. Therefore, it is necessary to understand the genitalia structure through dissection, but this process necessarily involves damage to the type specimen. To solve these problems, Micro-CT(Computed Tomography) which allows observation of internal structures without damage, was utilized to create a 3D model of the genitalia. In this study, the genitalia structure of Stathmopoda pedella (Linnaeus, 1761), the type species of Stathmopodidae, was imaged using Micro-CT under a resolution of 4 um conditions, providing a 3D description.

Over 350 species of Stathmopodidae have been reported worldwide, but due to their morphological similarities, there are many difficulties in species identification. To address these issues, various methods including larval, behavioral ecology, molecular techniques, and others have been utilized. In this study, we compared the resistance to pressure based on wing venation, which has not been extensively covered before, to further elucidate the differences between species. Type species, and one species from the genus reported in Korea, this study utilized Fusion 360 to create 3D models and visually represented resistance under the same pressure with colors. Colors derived from simulation results are extracted for trend analysis using PCA (Principal Component Analysis), and differences between groups formed through K-means clustering are analyzed.

One of the taxa of the superfamily Gelechioidea, Stathmopodidae, is widely distributed around the world, with 39 genera and 390 species reported as of 2015. This family shares the common characteristic of carrying their long hind tibia, but depending on the species, they have a variety of wing patterns and colors. Additionally, while there are species classified as pests for causing damage to grains and fruits, there are also species that feed on moss, spore of ferns and aphids. Consequently, they exhibit a diverse range of morphological and ecological characteristics. However, due to the lack of research and similarities between species, there is still much confusion in identification and phylogenetic analysis to date. In this current situation, further research intends to resolve the confusion in the phylogenetic sutdy of Stathmopodidae not only through morphological and molecular analysis but also by incorporation the latest technologies.

The family Stathmopodidae, which belongs to to the superfamily Gelechioidea, has 6 genera and 18 species reported in Korea to date. This family is classified as pests, causing serious damage to grains or fruits, depending on the species. Therefore, precise control is necessary, however, there is a lack of taxonomic and ecological research. We aim to analyze the clade and speciation timing for phylogenetic analysis of Stathmopodidae using ChatGPT, a tool that has recently garnered much attention. ChatGPT, a conversational AI chatbot developed by OpenAI, is accessible to anyone and being able to improve itself through conversations with users. In this study, we utilized the lengths of the generated lineage branches and the molecular clock rate to predict when certain species of the family Stathmopodidae diverged, measured in millions of years. However, further study is required to obtain more accurate figures.

The Gelechioidea is the second most species-rich group of Lepidoptera, but only limited number of mitochondrial genome (mitogenome) sequences is available. Thus, we sequenced the complete mitogenome of a gelechioid Hieromantis kurokoi (Lepidoptera: Stathmopodidae) to use the data for future study for the higher phylogeny of Ditrysia in Lepidoptera. The arrangement of the genome was identical to typical one found in Ditrysia (trnM-trnI-trnQ) (underline for inverted gene). The COI began with CGA, which has been designated as the start codon for majority of lepidopteran species, whereas other protein-coding genes (PCGs) began with the typical ATN codon. The 360-bp long A+T-rich region harbored the conserved sequence blocks Phylogenetic analysis using the 13 PCGs both by Bayesian inference (BI) and Maximum-likelihood (ML) methods indicated that H. kurokoi belonging to the family Stathmopodidae grouped together with within-familial species Atrijuglans hetaohei with the highest nodal support (BI, 1.0; ML, 100%).

The mitochondrial COI gene has proven successful for identifying the lepidopteran species. In addition, this gene has been applied to recognize cryptic species and confirm a polyphagous species as one species. However, it has been also reported misidentification in the COI gene. As a result, some researchers have suggested the use of additional genes in species identification, especially, nuclear genes. In this study, we observed that a nuclear EF1agene is better than the mitochondrial COI gene in recognizing Stathmopoda species. For example, among the all species, 47 individuals of nine species, a large intraspecific pairwise difference were detected, up to 15.0% in universal barcoding regions of the COI gene, 22.0% in other part of the COI gene; however, 2.0% in EF1a. In contrast, Stathmopoda sp2 and S. commoda were separated into several clusters in each different COI regions, and some individuals of S. auriferella and S. commoda, were closer to each other separating from the cluster of the same species. But, we get clear results from the EF1a, Stathmopoda species well clustered and could be distinguished.
