Explanation

To solve the question "A taxonomic group comprised of members of similar kingdoms is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understand Taxonomy**: Taxonomy is the science of classification of living organisms. It involves organizing species into hierarchical categories based on shared characteristics.

2. **Identify Taxonomic Ranks**: The main taxonomic ranks include domain, kingdom, phylum, class, order, family, genus, and species. Each rank represents a level of organization.

3. **Focus on the Question**: The question specifically asks for a taxonomic group that includes members of similar kingdoms. This indicates we need to look for a higher taxonomic rank that encompasses multiple kingdoms.

4. **Recognize the Highest Rank**: The highest taxonomic rank that includes similar kingdoms is the "domain." Domains are the broadest category in the biological classification system.

5. **Recall the Classification by Carl Woese**: In 1990, scientist Carl Woese proposed a system that divided life into three domains: Bacteria, Archaea, and Eukarya. Each of these domains contains various kingdoms.

6. **Conclude the Answer**: Therefore, the answer to the question is "domain," as it is the taxonomic group that comprises members of similar kingdoms.

### Final Answer:
A taxonomic group comprised of members of similar kingdoms is called a **domain**.
