Summary:
A reddish-brown clingfish with seven yellowish stripes: a stripe from the snout tip to the dorsal-fin origin, two stripes along the side, a narrow yellowish stripe on abdomen on either side of ventral midline, and small pale dots between the stripes along the back and sides, and a yellowish u-shaped line from each side of the pelvic disc to the ventral tip of the lower jaw.
In Australia, the Pacific Doubleline Clingfish has previously been known as Lepadichthys caritus, a junior synonym of L. lineatus, which is an Indian Ocean species: Red Sea, Arabian Sea, Seychelles and Sri Lanka.

Colour |
Body reddish-brown (or bright red), with seven yellowish stripes: one along the dorsal midline from snout tip to dorsal-fin origin; two stripes on each side - upper stripe from the middle of upper jaw through top of eye and above pectoral fin base to caudal fin base; lower stripe from rear of lower jaw running below pupil and middle of gill opening to caudal-fin base; abdomen with a narrow yellowish stripe on either side of ventral midline. |

Etymology |
The specific name is from the Latin geminus (= twin, double) in reference to the two yellow stripes under the abdomen, and the close morphological similarity of the new species to L. lineatus, with which it has previously been identified. |
