Summary
Detailed examination of Hymenopus coronatus head structures reveals new potential apomorphies for Mantodea and Dictyoptera. Cephalic morphology is crucial for understanding evolutionary adaptations in these insect orders.
Area of Science:
- Entomology
- Comparative Morphology
- Phylogenetics
Background:
- The evolutionary relationships within Dictyoptera, including Mantodea, are not fully resolved.
- Cephalic morphology offers valuable characters for phylogenetic analysis.
Purpose of the Study:
- To conduct a detailed examination of the external and internal head structures of Hymenopus coronatus.
- To compare these findings with existing literature and identify potential apomorphies (derived traits) for Mantodea and Dictyoptera.
Main Methods:
- Detailed morphological examination of Hymenopus coronatus head structures.
- Comparative analysis of observed features against established literature on insect head morphology.
Main Results:
- New potential apomorphies for Mantodea include: crests on anterior tentorial arms, a parietal suture, and specific glossae/paraglossae structures.
- Confirmed apomorphies for Mantodea include: head capsule shape, enlarged compound eyes, frontal shield, tentorial arm lobes, specific sutures, and mentum reduction.
- New potential apomorphies for Dictyoptera include: reduction of Musculus tentoriobuccalis lateralis (M. 49), a "perforate" tentorium, specific lacinial incisivi, and a postmola.
Conclusions:
- Cephalic morphology provides significant insights into the phylogenetic relationships of Mantodea and Dictyoptera.
- Further studies incorporating diverse taxa are essential for resolving evolutionary adaptations within Dictyoptera.

01:54Convergent Evolution
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.
01:23Phylogeny
Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.
02:31Synteny and Evolution
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral chromosome underwent...

01:27Diversity of Protists II
Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
01:12The Hyoid Bone
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...
01:51Lampbrush Chromosomes
In 1882, Flemming observed lampbrush chromosomes (LBC) in salamander eggs. Later in 1892, Rückert observed LBCs in shark egg cells and coined the term "lampbrush chromosomes" because they looked like brushes used to clean kerosene lamps.
LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops resemble the...
