Checked: verified by a taxonomic editorEtymology The etymology is not clear, but the name Thetisella seems to be composed by the postposition of the Latin suffix -ella, feminine form of -ellus and normally added to a noun to form a diminuitive of that noun, to Thetis, a variant transcription of Tethys, who in the Greek mythology was an aquatic sea godness, the daughter of Uranus and Gaia. The name seems to make reference to the small size of the species included in the genus, which were described based on larval forms.  [details]

Checked: verified by a taxonomic editorDiagnosis "The genus may be characterized thus:—a row of tubercles or feet on both sides in a single row, upon which are implanted a tuft of strong setae. Two(?) pairs of hooks or feet on the ventral surface near the anterior extremity, on the two first thoracic segments(?) A row of short spines disposed in a stellate-formed group along each side of the dorsal surface at a distance from the tubercles or feet. Dorsal surface rough externally." (Baird, 1868: 247-248).  [details]
