In 427 BC Servilius held the consulship together with Lucius Papirius Mugillanus. Nothing is known of the events during their consulship. Servilius would hold the imperium for three years, being elected as consular tribune for three consecutive terms, 419 to 417 BC. Servilius served together with Agrippa Menenius Lanatus, Publius Lucretius Tricipitinus and Spurius Nautius Rutilus in 419 BC. Little is recorded during the year. Servilius second term as consular tribune was together with Marcus Papirius Mugillanus and Lucius Sergius Fidenas. Sergius was defeated in battle by the Aequi and Labicani which lead to the appointment of a dictator. The dictator, a relative of Servilius named Quintus Servilius Priscus Fidenas, appointed Servilius as his magister equitum. They fought and defeated the Aequi and captured Labici. The year also saw the election of two censors, of which one was Servilius former consular colleague, Lucius Papirius Mugillanus. The third and final term, in 417 BC, Servilius served together with two of his former colleagues from 419 BC, Lucretius and Menenius, and a fourth, Spurius Veturius Crassus Cicurinus. Little is known of the events during the year.
This period in the history of the Roman republic suffers from severe lack of sources and fragmentation of the few existing sources. The few sources that survive are generally contradictionary to each other in regards to the identification of the consuls and consular tribunes of the period. Servilius, the consul in 427 BC, is given the cognomen Ahala by Livy, Structus by both Diodorus Siculus and the Chronograph of 354. Servilius the consular tribune of 419, 418 and 417 BC is given the cognomen Axilla by the Fasti Capitolini. Livy provides three different narratives for the consular tribune, he completely omits Servilius in 419, gives him the cognomen Priscus in 418 and the cognomen Structus in 417, identifying the consular tribune of 418 and 417 as two different individuals, and both separate from the consul of 427 BC. The Chronograph, Fasti and Diodorus all agree that the consular tribune of 419 to 417 BC should be identified as one individual, having held the title three terms in a row. Livy, confusingly, also names the tribune of 417 BC Lucius instead of Gaius. The classicist Broughton, following the arguments of two other scholars, Münzer and Mommsen, lists the consuls of 427 BC and the consular tribune of 419 to 417 BC as the same individual, Gaius Servilius Structus Ahala. Servilius colleagues are similarly hard to correctly identify, Both Lucius Papirius Mugillanus and Agrippa Menenius Lanatus could either be elder consuls, having held the consulship in 444 and 439 BC respectively, or younger consuls who held the consulship for the first time. In regard to the college of 417 BC the fourth individual differs between sources. Livy names him as Spurius Rutilius Crassus while Diodorus has him named Spurius Veturius Crassus Cicurinus. Livy has most likely confused the name with that of Spurius Nautius Rutilus, colleague of Servilius in 419 BC and one of the consular tribunes the following year in 416 BC, this in combination with that the Rutilii where plebeian and that no Rutilii would apear within the consular lists for another 250 years, strongly favors Spurius Veturius Crassus Cicurinus as provided by Diodorus.
