**Feedback on Pocotina: A Multigene Phylogeny of Eristaline Flower Flies**

Introduction

The study of Pocotina, a subtribe of eristaline flower flies, has been a subject of interest in the field of entomology. A recent publication by Moran, K.M., et al. (2021) has shed light on the phylogeny of this subtribe, providing valuable insights into the evolutionary relationships among its members. In this article, we will provide feedback on the study, highlighting its strengths and weaknesses, and discussing its implications for the field of entomology.

The Study's Significance

The study by Moran, K.M., et al. (2021) is significant because it provides a comprehensive multigene phylogeny of the eristaline flower flies, with a focus on the subtribe Criorhinina. The authors used a combination of molecular and morphological data to reconstruct the phylogenetic relationships among 34 species of Criorhinina. The study's findings have important implications for our understanding of the evolution and diversification of this subtribe.

Methodology and Results

The authors used a combination of molecular and morphological data to reconstruct the phylogenetic relationships among the species of Criorhinina. They sequenced 12 genes, including the mitochondrial COI and COII genes, as well as several nuclear genes. The authors also examined morphological characters, including the shape and size of the wings, the coloration of the body, and the shape of the antennae.

The results of the study show that the subtribe Criorhinina is divided into two distinct clades, which are supported by both molecular and morphological data. The first clade includes species with a more primitive morphology, while the second clade includes species with a more derived morphology. The authors also found that the species of Criorhinina are not monophyletic, and that several species are nested within the clade of the more derived morphology.

Strengths and Weaknesses

One of the strengths of the study is its comprehensive approach, which combines molecular and morphological data to reconstruct the phylogenetic relationships among the species of Criorhinina. The authors also used a robust phylogenetic method, which takes into account the uncertainty associated with the estimation of phylogenetic relationships.

However, the study has several weaknesses. One of the main limitations is the small sample size, which includes only 34 species of Criorhinina. This may not be representative of the entire subtribe, and may not capture the full range of diversity within Criorhinina. Additionally, the study relies heavily on morphological data, which may not be as informative as molecular data.

Implications and Future Directions

The study by Moran, K.M., et al. (2021) has important implications for our understanding of the evolution and diversification of the subtribe Criorhinina. The findings of the study suggest that the species of Criorhinina are not monophyletic, and that several species are nested within the clade of the more derived morphology. This has important implications for the classification and taxonomy of Criorhinina.

Future studies should aim to increase the sample size and include more species of Criorhinina. Additionally, the use of more advanced phylogenetic methods, such as Bayesian inference, may provide more robust estimates of phylogenetic relationships. The study also highlights the importance of combining molecular and morphological data to reconstruct phylogenetic relationships.

Conclusion

In conclusion, the study by Moran, K.M., et al. (2021) provides valuable insights into the phylogeny of the subtribe Criorhinina. The findings of the study have important implications for our understanding of the evolution and diversification of this subtribe. However, the study has several limitations, including a small sample size and the reliance on morphological data. Future studies should aim to increase the sample size and include more species of Criorhinina, as well as use more advanced phylogenetic methods.
