Explanation of Names
Moesta is Latin for sad or mournful.
The black speckles all over the forewing are nicely diagnostic. When compared to the similar genus Trichadentecnum you will see that Loensia lacks the arc of 6 spots in the last 1/4 of the wing (one in the base of each cell). The very dark (almost black) spot in the centre of the wing gives it away as moesta.
