Diogenes Laertius references numerous sources for Book X. Knowing the context of these excerpts would go a long way in determining whether we could generally apply these characteristics or whether they were addressing a specific instance. Caution should be exercised in some cases of overgeneralizing. In light of this, we should not assume this list of characteristics was extant somewhere else and simply DL copied it wholesale. Therefore, just because two or three characteristics follow each other, we cannot assume they're connected or related in any way, or conversely, assume they are not.
Diogenes Laertius cites the following sources by name for X.117-121 with the Hicks translation included to which the "citation" is attached:
Diogenes of Tarsus
Epitome of the Ethical Maxims of Epicurus
As regards women he will submit to the restrictions imposed by the law
Epilecta (collections of lectures)
love does not come by divine inspiration : so Diogenes in his twelfth book.
Referring probably to his collection entitled Epilecta, although Wikipedia states (without citation) it is referring to his Ethical Maxims.
The wise man will also feel grief, according to Diogenes in the fifth book of his Epilecta.
Epicurus
Problems - Διαπορίαι (can also translated as Questions)
Nor, again, will the wise man marry and rear a family : so Epicurus says in the Problems and in the De Natura.
De Natura - Περὶ φύσεως
Symposium - Συμπόσιον
Nor will he drivel, when drunken : so Epicurus says in the Symposium.
On Ways of Living/On Human Life - Περὶ βίων
Nor will he take part in politics, as is stated in the first book On Life
nor will he turn Cynic (so the second book On Life tells us)
But even when he has lost his sight, he will not withdraw himself from life : this is stated in the same book.
Diogenes of Tarsus is mentioned by name in X.25: "and Diogenes of Tarsus, who compiled the select lectures." According to Wikipedia:
Diogenes of Tarsus (Greek: Διογένης ὁ Ταρσεύς; fl. 2nd century BC) was an Epicurean philosopher, who is described by Strabo as a person clever in composing improvised tragedies. He was the author of several works, which, however, are lost. Among them are:
Select lectures (Greek: Ἐπίλεκτοι σχολαί), which was probably a collection of essays and dissertations.
Epitome of Epicurus’ ethical doctrines (Greek: ἐπιτομὴ τῶν Ἐρικούρου ἠθικῶν ζητημάτων), of which Diogenes Laërtius quotes the 12th book.
On poetical problems (Greek: Περὶ ποιητικῶν ζητμάτων), poetical problems which he endeavoured to solve, and which seem to have had special reference to the Homeric poems.
