To determine which of the following is not a real 'tagmata' of the body of a cockroach, we need to understand what tagmata are and the segmentation of a cockroach's body.

### Step-by-Step Solution:

1. **Understanding Tagmata**:
- Tagmata refer to the major body segments of an organism, particularly in arthropods. In the case of a cockroach, the body is divided into distinct sections.

2. **Identifying the Segments of a Cockroach**:
- The body of a cockroach is primarily divided into three main segments:
- **Head**: This segment contains the sensory organs and mouthparts.
- **Thorax**: This segment is responsible for locomotion and has the legs and wings.
- **Abdomen**: This segment contains the digestive and reproductive organs.

3. **Analyzing the Options**:
- The options given include:
- Head
- Neck
- Thorax
- Abdomen
- Among these, the head, thorax, and abdomen are recognized as true tagmata.

4. **Identifying the Incorrect Option**:
- The **neck** serves as a connecting structure between the head and thorax but is not considered a true segment or tagma of the cockroach's body.

5. **Conclusion**:
- Therefore, the option that is not a real tagmata of the body of a cockroach is **Neck**.

### Final Answer:
