The starry dwarf frog is an expert hider. Plunging into leaf litter at the slightest disturbance, it has successfully evaded attention for millions of years — until now. The thumbnail-sized species, now named Astrobatrachus kurichiyana, was discovered in India's Western Ghats. It's the sole member of an ancient lineage, a long branch on the frog tree of life that researchers have classified as a new subfamily, Astrobatrachinae.
