What is "protanilla"

Protanilla is a genus of ants in the subfamily Leptanillinae. Known from the Indomalaya ecozone, the genus contains eight species and at least one formally undescribed species, P. wallacei. The genus was erected by Taylor (1990) for the type species P. rafflesi, described from workers from Peninsular Malaysia. Four species are known from China (P. bicolor, P. concolor, P. gengma and P. tibeta), one from Taiwan (P. lini), one from Sri Lanka (P. schoedli) and one from India (P. wardi).
