Punctulus

Punctulus is a Latin noun meaning “small point, dot, or puncture.” The term is found in classical Latin literature where it describes a minute indentation or hole, such as the tiny marks on a stone or the shallow depressions on a surface. In the context of biology, the word punctulus is commonly used as a species epithet to denote the presence of punctate or dotted markings on an organism’s exoskeleton, wings, or skin. For example, several insect species in the families Coleoptera and Lepidoptera are named with the suffix punctulus to emphasize the distinct punctate patterning that characterises them.

In the history of punctuation, the Latin phrase punctulus is sometimes used to refer to a small pause or a semicolon, literally a small point that marks a division between sentences or clauses. The concept parallels the modern semicolon, which serves to separate related but independent clauses. Early manuscripts of Latin texts occasionally employed the punctuation mark now resembling a semicolon, and the term punctulus was occasionally applied to it.

As a scientific name, the exact taxonomy of “Punctulus” can vary; it has been applied to various genera in different families, often within insects. The use of the term is intended to convey a morphological feature—small, distinct, and minute—that is visually noticeable but not necessarily functionally significant. The name has been retained through botanical and zoological nomenclature for its descriptive precision and ease of identification by naturalists.
