### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for a specific type of zooflagellate that is capable of digesting cellulose and is found in wood cockroaches.

2. **Reviewing the Options**:
- **Option 1: Lophomonas**
- Lophomonas blatterum is a symbiont found in the intestines of wood cockroaches. However, it does not play a role in cellulose digestion. Therefore, this option is incorrect.
