Pygospila hyalotypa is a moth in the family Crambidae. It was described by Turner in 1908.[1] It is found in Papua New Guinea[2] and Australia, where it has been recorded from Queensland.[3]
The wingspan is about 46 mm. The forewings fuscous-grey, with a purple lustre. The spots are translucent and free from scales. There is a dot below the cell near the base, and another in the cell towards the base, as well as a quadrangular spot in cell, and another oval spot on the dorsal side of it below the cell. A quadrangular spot is found beneath the costa, it is bisected by vein 6. There is a smaller spot obliquely below this, bisected by vein 4. The hindwings have a sinuate termen. The colour is as the forewings, but there is one translucent spot only. It is located towards the base on dorsal side of the cell and is elongate-ovoid and narrower towards base.[4]
