Etymology. The specific epithet “ imeri ” is a noun in apposition and refers to the Imeri mountain massif where the species occurs. Generic placement. The new species is assigned to the genus Neblinaphryne based on its phylogenetic relationship as assessed by molecular data (Fig. 3) and its pointed (not T–shaped) terminal phalanges and minuscule septomaxillae, two osteological characters that were identified as diagnostic of the genus by Fouquet et al. (2024). Definition. A minute brachycephaloid frog characterized by: (1) SVL 15.9 ± 1.1 mm in males, 19.8 ± 0.5 mm in females (Table 1); (2) head wider than long, narrower than body; (3) tympanum indistinct, covered by skin and dorsally by a supratympanic fold, columella present (Fig. 6); (4) one prominent tubercle on each eyelid (creamcolored in life) and in the humeral region (white-tipped, Fig. 4); (5) frontoparietal smooth, cranial crests absent; (6) dentigerous process of vomer absent, vomers free of contact with any other bone; (7) subgular vocal sac, vocal slits present in males; (8) fingers fully developed without subarticular tubercles, finger tips not expanded, rounded on Finger I, pointed or mucronate on II and IV, mucronate on Finger III, without discs and circumferential grooves, terminal phalanges pointed; (9) outer metacarpal tubercle flat, drop-shaped, other tubercles on hands and fingers absent; (10) Finger I slightly shorter than Finger II; relative lengths of fingers: I
