2. **Poaceae**: This is also an order, specifically referring to the grass family.
3. **Insecta**: This is a class that includes insects, which is a higher taxonomic rank than an order.
4. **Diptera**: This is an order that includes true flies.

Now, let's break down the steps to determine which option does not belong to the same rank:

### Step 1: Identify the taxonomic ranks of each option
- **Primata**: Order
- **Poaceae**: Order
- **Insecta**: Class
- **Diptera**: Order

### Step 2: Compare the ranks
