Etymology: Flexor: Name from Latin 'flexus', past participle of 'flectere', to bend, referring to the great flexibility of clingfishes, many of which have the ability to bend the body so that the tail end comes to lie close to the head; incus: Name from Latin 'incus' word for anvil, referring to the anvil-like outline of Raoul Island, the largest island in the Kermadec archipelago and type locality of the new species; noun in apposition.

Short description
Identification keys | Morphology | Morphometrics
This species is distinguished by the following characters: head and anteriormost part of body similar in width; relatively elongate body with a small, double adhesive disc beneath the anteriormost part of the body; an oval-shaped gap between the premaxillae formed by a semicircular indentation along medial edge of premaxilla; premaxilla with a single row of teeth, with 2-3 peg-like, conical teeth anteriorly at, and adjacent to, symphysis and 10-12 strongly laterally compressed, incisiviform teeth with strongly recurved cusp, along the outer margin of bone; lower jaw with a single row of 14-16 small, conical teeth with sharply pointed and slightly recurved tip; posterior tip of the basipterygium expanded and articulating with anteromedial edge of ventral postcleithrum via a shallow concave facet; mandibular part of preoperculo-mandibular lateral line canal absent; lachrymal canal with 2 pores; upper and lower lip simple, uniform in thickness along jaw margin (Ref. 124119).
Known only from the intertidal and subtidal waters of the Kermadec Islands, including Raoul Island and L’Esperance Rock. Most of the specimens collected using ichthyocides were from rock pools and from shallower subtidal areas (down to 9 meters) over rock and coral rubble. A single specimen has been observed and photographed at 28 meters in depth (Ref. 124119).
