A purplish dwarfgoby with with orange-reddish spots, and a dark brown spot or bar extending from the rear of the eye.
T caesiura has a red body with white spots. T maiandros has a purplish body with orange/red spots. I've sent (poor) photos of T maiandros I've seen in Fiji to Rick Winterbottom who confirmed the identification. The bright violet color of your fish is the key to me

Rowley Shoals and Scott Reef, Western Australia, Ashmore Reef and Cartier Reef, Timor Sea, northern Great Barrier Reef  to Swains Reefs, Queensland; also reefs in the Coral Sea, and Cocos (Keeling) Islands in the eastern Indian Ocean. Elsewhere, the species occurs in the tropical, east-Indo-west-central Pacific.
Inhabits mid to outer barrier reefs, being much more common on outer barrier islands, and also found in caves and crevices.


Dorsal fin VI-VII + I, 8-10; Anal fin I, 7-9; Vertebrae: 26. 
Reduced predorsal scales, usually not crossing the midline (midline naked or partly naked); cycloid scales at sides of nape reaching to above a point between posterior margin of operculum and eyes; no scales on cheeks nor opercles; pectoral base usually fully scaled, posterodorsal 2 scales slightly enlarged; prepelvic covered with small cycloid scales in 5-6 rows; interorbital narrow, with moderate groove; groove absent or very shallow behind eyes (shallow between eyes and absent behind eyes in juveniles); a low distinct ridge at posterior end of interorbital; gill opening extending forward to below posterior margin of pupil; nape crest low from first dorsal origin to above posterior opercular margin, reaching to the shallow median groove; groove extending to just behind eyes; pectoral rays unbranched or with 1-5 rays branched at extreme tips; fifth pelvic ray unbranched, rest of rays with 2 terminal tips; D2 usually I,9; A usually I,8; pelvic fins largely separate, connected only at base; fins widely separate, distance between 2 fins greater than base of single pelvic fin; pelvic scale covering membrane, with fifth ray about one-fourth to one-half length of fourth ray.


The species is named maiandros for Maiandros, the god of the winding Maeander River in Phrygia (currently known as the Büyük Menderes River in Turkey), son of Oceanus and his sister Tethys. The English word 'meander', a winding, crooked, or involved course, is in allusion to the zigzag pattern of grey to blue lines on the body.
