Question

The opposite sex specimen described along with holotype is called

• A. Paratype
• B. Biotype
• C. Allotype
• D. Syntype

Hint:

Remember the prefix meanings:
Holo- $\rightarrow$ Single unique type.
Allo- $\rightarrow$ Other (opposite sex) type.
Para- $\rightarrow$ Supplementary type series.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Taxonomic descriptions of new species require designating specific physical specimens (type specimens) to act as biological benchmarks, as regulated by the International Code of Zoological Nomenclature (ICZN).

Step 2: Detailed Explanation:
Let us define the type designations used in zoological nomenclature:
Holotype: The single specimen designated by the author in the original publication to serve as the unique standard representing the species.
Paratype: Any specimen of a type series other than the holotype, used by the author to describe the morphological variation of the new species.
Syntype: One of several specimens of equal status used by an author to describe a species when no holotype was originally designated.
Biotype: A group of individuals having the same genotype, which is a biological term, not a nomenclatural type.
Allotype: A designated paratype specimen of the opposite sex to the holotype, described in the original publication to highlight sexual dimorphism.
Because many insect species exhibit high sexual dimorphism (males and females looking very different), designating an allotype is essential for correct species identification.
Therefore, the opposite sex specimen described alongside the holotype is known as the allotype.

Step 3: Final Answer:
The opposite sex specimen described along with the holotype is called the Allotype.
