Description

Males measure {{convert|26|-|30|mm|abbr=on}} and females {{convert|32|-|34|mm|abbr=on}} in snout–vent length. The snout is short. The tympanum is distinct or indistinct, partly hidden by the swollen, light-coloured supratympanic fold. The skin of upper surfaces and flanks is smooth with tubercles; tubercles usually form dorsolateral rows, with a weak, X-shaped ridge between them, and four–five transverse rows on shanks. There is a small, horn-like tubercle at the edge of the eyelid. Ventral surface is smooth. Colouration above is red brown or olive brown, with the dorsum bearing a dark, reticular marking.^[1]

Males have a single vocal sac. Based on calling males, reproductive season is April–September. Tadpoles are unknown.^[1]

Distribution and habitat

This newly described species is known from three locations on the Luoxiao Mountains: Jingzhushan (the type locality) on the Jinggang Mountains in Jiangxi, and Dayuan and Lishuzhou, both in the Yanling Taoyuandong National Nature Reserve, Hunan. It lives in mountainous swamps surrounded by subtropical moist evergreen broadleaf forests at elevations of {{convert|1200|–|1530|m|abbr=on}} asl.^[1]

Two other Megophrys species occur in the area, but the three species differ in their habitats: Megophrys jinggangensis live in slow-moving streams at {{convert|700|–|850|m|abbr=on}} asl, and Megophrys lini in rushing streams at {{convert|1100|–|1610|m|abbr=on}} asl. The species also differ in the characteristics of the male advertisement calls.^[1]
