We describe a new horned toad species of the genus Megophrys from Yingjiang County of Yunnan Province, China. The new species, Megophrys feii sp. nov., can be distinguished from its congeners by a combination of the following characters: (1) body slender and small (SVL 24.3-25.1 mm in four males, 28.2-28.9 mm in two females); (2) head length about equal to head width (HDL/HDW 0.97-0.99); (3) tympanum circular and distinct; (4) maxillary teeth present; (5) vomerine ridges and vomerine teeth absent; (6) tongue round, slightly notched posteriorly; (7) tibia long (TIB/SVL 0.48-0.52 in four males, 0.54-0.55 in two females), shanks overlapping when thighs are held at right angles to the body; (8) dorsal skin distinctly granular and densely covered with small tubercles; (9) lower flanks and lateral sides of belly scattered with small but prominent, white, tubercles; (10) webbing between toes rudimentary; (11) lateral fringes on toes moderate to wide; (12) breeding males without nuptial pads and spines on fingers; (13) protruding projection posterior to cloaca present in both sexes; (14) groin and ventral thigh coloration in life not contrasting with surrounding regions; (15) the presence of an indistinct and small horn-like tubercle at the edge of the eyelid; and (16) an advertisement call with a dominant frequency of 4.74-4.91 kHz (at 18 ˚C). To date, the new species has only been found at its type locality in stream areas in montane evergreen broadleaf forests between 700-1200 m elevation.
我们描述了一种来自中国云南省盈江县的新角蟾属物种。新物种费氏角蟾(Megophrys feii sp. nov.)可通过以下特征组合与同属其他物种区分开来:(1)身体细长且小(4只雄性的体长为24.3 - 25.1毫米,2只雌性的体长为28.2 - 28.9毫米);(2)头长约等于头宽(头长/头宽为0.97 - 0.99);(3)鼓膜圆形且明显;(4)有上颌齿;(5)无犁骨嵴和犁骨齿;(6)舌圆形,后端略有缺刻;(7)胫骨长(4只雄性的胫长/体长为0.48 - 0.52,2只雌性的为0.54 - 0.55),当大腿与身体呈直角时小腿相互重叠;(8)背部皮肤明显呈颗粒状,密布小瘤;(9)腹部两侧和下侧散布着小而突出的白色瘤;(10)趾间蹼不发达;(11)趾侧缘膜中等至宽;(12)繁殖期雄性手指上无婚垫和刺;(13)两性泄殖腔后方均有突出的突起;(14)生活时腹股沟和大腿腹面颜色与周围区域无明显差异;(15)眼睑边缘有一个不明显的小角状瘤;(16)鸣声主频为4.74 - 4.91千赫兹(18℃时)。迄今为止,该新物种仅在其模式产地海拔700 - 1200米的山地常绿阔叶林溪流区域被发现。
