Eponymy: Leonard R ‘Len’ Thomas was an Australian scientist who was Honorary Associate of the Australian Museum. He helped to plan, and accompanied, the Museum’s (1962) Swain Reefs Expedition, during which paratypes of the triplefin were collected. (Ref. 128868), visit book page.

Dorsale stekels (totaal) : 18 - 19; Dorsale zachte stralen (totaal) : 9 - 11; Anale stekels: 2; Anale zachte stralen: 20 - 22. Scales from head posteriorly to behind the eye but none on cheek; lobate supraorbital tentacle; body coloration white; yellow or orange on scale edges; 6 uneven, oblique, dark brown bands bifurcating ventrally; uneven brown bar below eye with white posterior border; females with thin, oblique, red and white bands on second and third dorsal fins; dull orange in males. Dorsal rays IV + XIV-XV + 9-11 (typically XV + 10); pectoral rays usually 15; lateral line discontinuous, 12-15 + 24-27; mandibular pores 3 + 2 + 3 (Ref. 54980).
Body shape (shape guide): elongated.
Adults are found in coral reefs and intertidal pools (Ref. 13227). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
