Explanation:

When it comes to English Grammar, a signal phrase is a type of phrase sentence or clause that often introduces a quotation, paraphrase, or summary. This type of phrase contains a verb together with the name of the person that is being quoted.  

It alerts the reader that something taken from an entirely different source is about to be used.  

Below is an example:

Daniel testified that he was not in the house when his neighbor’s dog died (13).

The author’s name is included and the page number in parenthesis.

So when the author’s name does not appear in the text, you should not use the author’s last names in the citation.
