Options

A. Lectotype
B. Neotype
C. Syntype
D. Paratype

Answer

To answer the question, "Type specimen selected from the original material in case the holotype is missing, is called:", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Type Specimens**:
- Type specimens are crucial in taxonomy as they serve as a reference for the identification of species. The holotype is the single specimen designated as the representative of a species.

2. **Identify the Role of Holotype**:
- A holotype is a specific specimen that is used to describe a species. It is the primary reference point for that species.

3. **Recognize the Issue of Missing Holotype**:
- In some cases, the holotype may be lost or unavailable. This presents a challenge in taxonomy as the reference for the species is no longer accessible.

4. **Define Lactotype**:
- When the holotype is missing, a lactotype is selected from the original material. A lactotype serves as a substitute to represent the species in the absence of the holotype.

5. **Differentiate Between Lactotype and Other Types**:
- It is important to note that there are other types of specimens, such as syntypes (more than one specimen designated when no holotype is available) and neotypes (a new type specimen designated when all original types are lost).

6. **Conclude with the Correct Answer**:
- Based on the definitions and understanding, the type specimen selected from the original material when the holotype is missing is called a **Lactotype**.

### Final Answer:
The type specimen selected from the original material in case the holotype is missing is called a **Lactotype**.
