Geometric Morphometric Analysis

The genus Haematobosca Bezzi, 1907 (Diptera: Muscidae) contains haematophagous flies of veterinary importance. A new fly species of this genus was recognised from northern Thailand based on morphological characters and described as Haematobosca aberrans Pont, Duvallet & Changbunjong, 2020. In the present study, the mitochondrial cytochrome c oxidase I (COI) gene was used to confirm the morphological identification of H. aberrans. In addition, landmark-based geometric morphometrics was used to determine sexual dimorphism. The molecular analysis was conducted with 10 COI sequences. The results showed that all sequences were 100% identical. The sequence was not highly similar to reference sequences from GenBank and did not match any identified species from Barcode of Life Data Systems (BOLD). Phylogenetic analysis clearly differentiated this species from other species within the subfamily Stomoxyinae. For geometric morphometric analysis, a total of 16 wing pictures were analysed using the landmark-based approach. The results showed significant differences in wing shape between males and females, with a cross-validated classification score of 100%. The allometric analysis showed that wing shape has no correlation with size. Therefore, the COI gene is effective in species identification of H. aberrans, and geometric morphometrics is also effective in determining sexual dimorphism.

Geometric Morphometric Analysis

Geometric morphometric analysis recently has expanded to insects of forensic importance, mainly adult flies, as correct and valid species identification is important in forensic entomology. The objective of this research was to investigate morphological variations between two forensically important scuttle flies (Diptera: Phoridae) in Malaysia, i.e. Megaselia scalaris (Loew, 1866) and Megaselia spiracularis Schmitz, 1938, based on wing shape analysis. A total of 16 geometrical landmarks was defined and analysed with geometric morphometric procedures using MorphoJ software. Wing centroid size, which represented wing shape, was statistically different between species and sexes. By using residuals from the allometric effect, canonical variate analysis separated all defined groups in different distinct clusters and further cross validated by both species and sexes. Between species, male M. scalaris had broader wing shape than male M. spiracularis, whilst in the female, M. scalaris had a narrower shape at the tip of the wing. Within M. scalaris group, females had broader wing shape at the base than males, whereas in M. spiracularis, the females had narrower shape at the base of the wing than the males. The geometric morphometric analysis in distinguishing forensically important species could be expanded for further investigation, especially in Phoridae family.

Geometric Morphometric Analysis

The morphological features of an organism are an important source ofinformation for many areas of biological study. Insect wing architectural designis believed to be an excellent system for studying morphological variation becauseof their firm or solidly cleared structures. It has been the center of geometricmorphometric investigation in the past since insect’s wing pattern can providedetails on their evolutionary history and flight performance. Wing shape andsize disparity of fifty-nine individuals of bumblebee was explored to explain andfigure out biological structure variation within similar species. Examination inboth left and right forewings and hind wings was also considered to find out ifphenotypic sexual dimorphism exists. The outline-based geometric morphometrictechnique was employed in this study to measure and evaluate wing shape andsize variation among bumblebees. Results from mean shapes and scatter plotdiagrams analysis revealed that individuals of bumblebee differ less with respect to shape. Overlapping of individuals is visible on both wings in both sexes, which shows absence of dimorphism. Male individuals have larger forewings comparedto females. Slight variation was observed for both sexes in terms of hind wings,which indicates that both individuals exhibit common size characteristic andabsence of dimorphism. The study concludes that size may be considered as abasis for sex determination and that wing size is somewhat a sexual dimorphictrait among bumblebee species. Keywords - Biology, wing morphometry, outline-based geometric morphometric analysis,Philippines

Morphological And Molecular Data

The recent catalogues of the family Dolichopodidae considered Syntormon pallipes (Fabricius, 1794) and S. pseudospicatus Strobl, 1899 as separate species. In this study, we used three approaches to estimate the significance of differences between the two species: molecular analysis (COI and 12S rRNA sequences), analysis of leg colour characters and geometric morphometric analysis of wing shape. The morphological data confirmed the absence of significant differences between S. pallipes and S. pseudospicatus found in the DNA analysis. Significant differences in the wing shape of two species have not been revealed. Hence, according to our data, there is no reason to consider S. pseudospicatus as a distinct species.
