Scoparia spinosa is a moth in the Crambidae family. It was described by Li, Li and Nuss in 2010. It is found in China (Guangdong, Guizhou, Hainan, Hong Kong, Hunan, Sichuan) and Taiwan.
The length of the forewings is 5–5.5 mm. The forewings are sparsely suffused with blackish brown scales. The antemedian and postmedian lines are white. The hindwings are white to pale brown.
The species name refers to the phallus with many small spinelike cornuti in the male genitalia and is derived from Latin spinosus (meaning spinous).
