Boulenophrys changyangensis sp. nov. Type materials. Holotype. • MT CY 20220806005 (Figs 3, 4), adult male, from Changyang County, Hubei Province, CHINA (30.5732°N, 110.9404°E, ca. 616 m a. s. l.), collected by Jing Liu on 6 August 2022. Paratype. Four male specimens collected from the same place as holotype. • MT CY 20220806002, MT CY 20220806004, and MT CY 20220806006 collected on 6 August 2022 by Shize Li. Diagnosis. Boulenophrys changyangensis sp. nov. is assigned to the genus Boulenophrys based on molecular phylogenetic analyses and the following generic diagnostic characters: snout shield-like; projecting beyond the lower jaw; canthus rostralis distinct; chest glands small and round, closer to the axilla than to midventral line; femoral glands on rear part of thigh; vertical pupils (Fei and Ye 2016; Lyu et al. 2023). Boulenophrys changyangensis sp. nov. could be distinguished from its congeners by a combination of the following morphological characters: body size moderate (SVL 39.4–43.3 mm in males); a small horn-like tubercle at edge of each upper eyelid; vomerine ridges and vomerine teeth absent; tongue not notched behind; head width larger than head length; no large, pale-white circular spots on the shoulders; toes without webbing and lateral fringes; heels overlapped when thighs are positioned at right angles to the body; an internal single subgular vocal sac in males; in breeding males, the nuptial pads with black nuptial spines on the dorsal bases of the first and second fingers. Description of holotype: MT CY 20220806005 (Figs 3, 4). SVL 41.3 mm; other measurements are detailed in Table 3; head width larger than head length (HDW / HDL ratio about 1.12); snout rounded in dorsal view and protruding beyond lower jaw in profile; canthus rostralis distinct; loreal region sloping; dorsal surface of head flat; nostril orientated laterally, closer to snout than eye; internasal distance slightly larger than interorbital distance; eye large, eye diameter 35.1 % of head length; tympanum distinct, upper margin in contact with supratympanic fold and TYP / EYE ratio 0.79; vomerine ridges and vomerine teeth absent; margin of tongue smooth, not notched behind; a single subgular vocal sac present. Forelimbs slender, and the length of lower arm and hand is 48.0 % of SVL; relative finger length I
