Thymiatris microloga is a moth in the Xyloryctidae family. It was described by Diakonoff in 1966. It is found on Java. The wingspan is 37-41 mm.

There is sometimes an inwardly-oblique series of short darker streaks along the veins, this series runs from the costa before the apex to the dorsum well before the tornus. A series of rather large pale ochreous spots is found on the ends of veins 3 to 9, becoming smalle
