Abstract The taxonomic characters of the 34 known species of the genus Trichodrilus Claparède, 1862 are discussed as a basis for a systematic revision of the genus. Some additions to the species descriptions are made subsequent to examination of type collections. Trichodrilus campoyi Rodriguez, 1988, originally described as a subspecies of T. strandi Hrabě, 1936, is emended to specific rank. Trichodrilus icenorum Beddard, 1920 is regarded as a synonym of T. allobrogum Claparède, 1862. The extension of pharyngeal glands is demonstrated to be a fixed or a variable character depending on the species. Presence or absence of posterior lateral blood vessels or pattern of anterior blood vessels are not well documented for a significant proportion of the species and these characters need to be tested for environmentally induced variation. Taxonomic value of structural traits is strengthened against characters related to size. Thus, a key to the species of the genus is provided, emphasising such structural characters.
