Answer

To solve the question regarding which arthropod belonging to Onychophora possesses nephridia, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for an arthropod that belongs to the class Onychophora and possesses nephridia.

2. **Identify the Options**: The options provided are:
- Limulus
- Peripatus
- Daphnia
- Lepisma

3. **Analyze Each Option**:
- **Limulus**: Known as the king crab, Limulus belongs to the class Merostomata, which is not part of Onychophora. Therefore, it cannot be the correct answer.
- **Peripatus**: This organism is indeed part of the class Onychophora. It is often considered a connecting link between arthropods and annelids. Importantly, Peripatus possesses nephridia, which are excretory structures similar to those found in annelids. Thus, this is a strong candidate for the correct answer.
- **Daphnia**: Daphnia belongs to the class Crustacea within the phylum Arthropoda. It does not belong to Onychophora, so it cannot be the answer.
- **Lepisma**: Commonly known as silverfish, Lepisma belongs to the class Insecta of Arthropoda. It also does not belong to Onychophora, making it an incorrect choice.

4. **Conclusion**: After analyzing all the options, it is clear that the only organism that fits the criteria of being an arthropod belonging to Onychophora and possessing nephridia is **Peripatus**.

### Final Answer:
**Peripatus**
